METHODS: The clinical records of all premature infants with or without ROP and with or without treatment between 2007 and 2017 were retrospectively reviewed. Basic demographic data, serial changes in ROP incidence, treatment and outcomes, and the refractive states were analyzed. Correlations among myopia and astigmatism progression, birth weight, gestational age, and treatment methods were also analyzed.RESULTS: A total of 562 screened premature infants(all Chinese, 1124 eyes), were recruited with a 378:184 maleto-female ratio. Birth weight did not directly influence ROP incidence. The overall ROP incidence was 16.55%(93/562 cases). The incidences in boys and girls were 16.14%(33/378 cases) and 17.39%(32/184 cases), respectively, and this difference was not significant. However, all infants with serious ROP(stage IV and V) were male. Myopia combined with astigmatism was common in premature infants with and without ROP(30.99%, 172/555 cases), and myopic refraction(including myopia and myopia combined with astigmatism) was more common in premature infants with ROP(48.84%, 42/86 cases). In the >8.00 diopter group, there were significantly more ROP infants than without ROP. Myopic refraction(including myopia and myopia combined with astigmatism) was most common in infants with ROP after treatment(63.63%, 7/11 cases). CONCLUSION: The refractive state is different between premature infants and mature infants. Those treated for ROP had a higher chance of developing myopia, astigmatism, and higher diopter.展开更多

Results showed that corpus callosum length as well as thickness of the genu and splenium increased with gesta- tional age and birth weight, while other measures did not. These three factors on the standard mid-sagittal plane are therefore likely to be suitable for real-time evaluation of corpus callosum de- velopment in premature infants using cranial ultrasound. Further analysis revealed that thickness of the body and splenium and the anteroposterior diameter of the genu were greater in male infants than in female infants, suggesting that there are sex differences in corpus callosum size during the neonatal period. A second set of measurements were taken from 40 premature infants whose ges- tational age was 34 weeks or less. Corpus callosum measurements were corrected to a gestational age of 40 weeks, and infants were grouped for analysis depending on the outcome of a neonatal behavioral neurological assessment. Compared with infants with a normal neurological assessment, corpus callosum length and genu and splenium thicknesses were less in those with abnormalities, indicating that corpus callosum growth in premature infants is associated with neurobehavioral development during the early extrauterine stage.展开更多

Method: We used the Amiel-Tison neurologic examination, the Bayley Scale of Infant Behavior, and electroencephalography (EEG) recordings at 42 weeks of conceptional age, and after 6 months of treatment EI-K (n = 14) and compared these results with those of a group of infants without early intervention (nEI) (n = 11). Results: We found better performance of infants in EI-K than nEI group after 6 months of treatment in neurologic and behavioral examination measurements, but found no differences in EEG comparisons. Conclusion: Our data suggest significant benefit of the use of EI-K program over n-EI in the neurologic and neurobe-havior examinations of premature infants after 6 months of age.展开更多

There is an increasing evidence for improved outcomes regarding the resuscitation and stabilisation of extremely preterm infants but there is a lack of evidence in the periviable(gestational age 23-25 wk) preterm subgroup. Presence of an experienced team during the delivery of extremely preterm infant to improve outcome is reviewed. Adaptation from foetal to neonatal cardiorespiratory haemodynamics is dependent on establishing an optimal functional residual capacity in the extremely preterm infants, thus enabling adequate gas exchange. There is sufficient evidence for a gentle approach to stabilisation of these fragile infants in the delivery room. Evidence for antenatal steroids especially in the periviable infants, delayed cord clamping, strategies to establish optimal functional residual capacity, importance of temperature control and oxygenation in delivery room in extremely premature infants is reviewed in this article.展开更多

All preterm infants received supplements of vitamin E (20 IU) and iron (20 mg) each day. Our results showed that postnatal decline of hemoglobin (Hb) and hematocrit (Hct) were lessened in the treatment groups, particularly in the group 2 and the differences were very significant (P<0. 0001 for all). Treated infants had significantly higher reticulocyte counts (Ret) (P<0. 000] for all), but there was no significant difference between the two treatment groups (P>0. 05). Serum iron dropped significantly in the treatment groups as compared with control group (P<0. 01 for all), but no dose-dependent relationship was observed in treated infants (P>0. 05). After treatment, serum levels of erythropoietin was higher in group 2 than those in group 1 and control group (P<0. 0001, P<0. 01 and P<0. 05, respectively). There was no significant difference between group 1 and control group (P>0. 05). No side effects related to rhEpo therapy were observed. Our study suggested that rhEpo therapy stimulates endogenous erythro-poiesis and enhances Ret, Hct and level of Hb in a dose-dependent manner in premature infants. The therapy is more efficient when given in higher dosages.展开更多

Methods A randomized controlled trial for the prevention of neonatal intraventricularhemorrhage (IVH) was carried out in 57 Chinese premature infants with gestation of 34 weeks. These prematureinfants were randomly assigned to prevented (23 cases) or control (34 cases) groups. Results No statisticallysignificant differences in general data between the two groups were found. It was noticed that the average Apgarscore in prevented group was lower than that in the control group. The average age at the time of the loading dosesof phenobarbital was 8.9± 8.3 (0.5~25)h (outborn babies usually delay to receive phenobarbital), and the averageduration of the maintenance dose was 5d. The mean value of serum phenobarbital level obtained on day 4 was 20.9±5.2mg/L. The results demonstrated that the incidence of IVH and severe IVH decreased significantly inprevented group (74% vs 97%, P<0.05 and 13% vs 62%, P<0.01 respectively). NO severe IVH and hydrocephaluswere develOPed in the infants with IVH grade Ⅱ in the prevented group. While 7 infants with grade Ⅱ developedgrade Ⅲ during very short period, and 2 infants had to shunt for hydrocephalus in the control group. Infants onphenobarbital had not observed any side - effects. The duration of clinical symptoms was markedly shortened in theprevented group. Conclusion The study supports the use of phenobarbital for the prevention of IVH and severeIVH in Chinese premature infants. It is suggested that phenobarbital prophylaxis should be routinely carried outin all preterm infants with gestational age 34 weeks within 6h alter birth.展开更多

Approximately 9.6% of infants are premature and they can be at risk for hospitalization. This study has done for evaluation of awareness and knowledge of parents about problems of premature infants in Neonatal Intensive Care Unit (NICU). This was a descriptive study with 160 parents whose premature infants were admitted to NICU (Tehran-Iran, 2009-2011). Data were collected by a questionnaire for evaluation of awareness and knowledge of parents about problems of prematurity, and then analyzed by using descriptive analytic statistical methods and SPSS software. Based on the results, there was a significant relation between age and the total score of questionnaire (P = 0.022, R = 0.18). Mothers had higher awareness and knowledge than fathers (P < 0.05). The most awareness in parents was about doing of hygienic principle when they entered to NICU and about the importance of regularly and continuous attendance in ward. Awareness and knowledge of parents about problems of their premature infant were related to their age and being a mother or father. Parents had little knowledge about some NICU principles and premature infant’s needs and care.展开更多

Several management rules of taking care of preterm infants have been developed but have not been put into action. The geo-graphical inaccessibility to specialized hospitals and the weakness of the reception capacity of the care centers hinder the management of the complications associated with preterm birth. Purpose: The present study is designed to present some epidemiological data of preterm births within the Provincial Hospital Center of Missour during 2012 and to discuss the various problems emerging in the management of treatment and care. Materials and Methods: Retrospective study of preterm births in the maternity ward in the Hospital of Missour during 2012. Results: 37 preterm births among 1121 (3.3%) have been analyzed (51.3% severe premature infants, 45.9% late preterm infants and 2.7% extremely premature infants). 64.2% are originally from difficult areas to reach during winter. All mothers have received upon arrival at the maternity a corticosteroid and calcium antagonists (Adalate*) and an antibiotic treatment to those with a positive infectious anamnesis found in half of the women. We have recorded 3 twin pregnancies and 2 gravidic toxemias. Only 21 babies have been given back to their mothers (namely 56.7%). 5 premature infants (namely 13%) have been referred to the university hospital center of Fez (2 respiratory distress, a malformation and 2 severe premature births) given that there is an absence of a specialized care unit at the hospital, knowing that no baby has received neither surfactant nor caffeine at birth. 14 premature babies (namely 37.8%) have been transferred to the pediatric unit with a total death rate of 16.2% (6 premature) mainly related to neonatal infection and to suffering of the hyaline membranes disease. Conclusion: We emphasize the interest of prevention programs which demand an early diagnosis of preterm birth threats and monitoring high-risk pregnancies, improving the medical care given to low-weight premature by creating “Kangaroo” units at a regional level and the targeting of measures for rural and under-covered areas.展开更多

Methods: Randomized controlled trials (RCTs) or quasi-RTCs regarding the effect of TCM in low birth weight premature infants were retrieved in electronic databases such as the Cochrane Library, PubMed, EMbase, Web of Science, CBM (Chinese Biomedicine Database), CNKI (China National Knowledge Infrastructure), VIP (Chinese Scientific Journals Database) and Wanfang Database. Then, we adopted RevMan 5.3 software to perform a meta-analysis. Results: A total of 11 articles were included, including 1282 preterm infants. The result showed that compared with the routine care model, TCM can effectively increase the weight when premature infants discharged one week [MD=225.57, 95%CI (171.78, 279.37), P<0.001], increase the weight after discharged one month [MD=0.89, 95%CI (0.72, 1.06), P<0.001], increase the weight after discharged three months [MD=670.44, 95%CI (527.65, 813.23), P<0.001], promote the height of newborns [MD=4.54, 95%CI (2.42, 6.65), P<0.001], reduce readmission rate [RR=0.38, 95%CI (0.25, 0.58), P<0.001], alleviate adverse skin reactions [RR=0.33, 95%CI (0.22, 0.50), P<0.001], increase nursing satisfaction of the families [RR=1.21, 95%CI (1.13, 1.31), P<0.001]. Conclusion: TCM can effectively promote the growth and development of the low birth weight premature infants, reduce the hospital readmission rate, alleviate adverse skin reactions of premature infants and improve the nursing satisfaction of the families. However, due to the limitation of the region and quality of the included studies, which the accuracy of the result still be treated with more caution. Further high-quality studies are needed to verify the conclusion.展开更多

文摘AIM:To quantitatively assess the changes in mean vascular tortuosity(mVT)and mean vascular width(mVW)around the optic disc and their correlation with gestational age(GA)and birth weight(BW)in premature infants without retinopathy of prematurity(ROP).METHODS:A single-center retrospective study included a total of 133(133 eyes)premature infants[mean corrected gestational age(CGA)43.6wk]without ROP as the premature group and 130(130 eyes)CGA-matched fullterm infants as the control group.The peripapillary mVT and mVW were quantitatively measured using computerassisted techniques.RESULTS:Premature infants had significantly higher mVT(P=0.0032)and lower mVW(P=0.0086)by 2.68(10^(4) cm^(-3))and 1.85μm,respectively.Subgroup analysis with GA showed significant differences(P=0.0244)in mVT between the early preterm and middle to late preterm groups,but the differences between mVW were not significant(P=0.6652).The results of the multiple linear regression model showed a significant negative correlation between GA and BW with mVT after adjusting sex and CGA(P=0.0211 and P=0.0006,respectively).For each day increase in GA at birth,mVT decreased by 0.1281(10^(4) cm^(-3))and for each 1 g increase in BW,mVT decreased by 0.006(10^(4) cm^(-3)).However,GA(P=0.9402)and BW(P=0.7275)were not significantly correlated with mVW.CONCLUSION:Preterm birth significantly affects the peripapillary vascular parameters that indicate higher mVT and narrower mVW in premature infants without ROP.Alterations in these parameters may provide new insights into the pathogenesis of ocular vascular disease.

文摘BACKGROUND The common cause of sodium nitrite poisoning has shifted from previous accidental intoxication by exposure or ingestion of contaminated water and food to recent alarming intentional intoxication as an employed method of suicide/exit.The subsequent formation of methemoglobin(MetHb)restricts oxygen transport and utilization in the body,resulting in functional hypoxia at the tissue level.In clinical practice,a mismatch of cyanotic appearance and oxygen partial pressure usually contributes to the identification of methemoglobinemia.Prompt recognition of characteristic mismatch and accurate diagnosis of sodium nitrite poisoning are prerequisites for the implementation of standardized systemic interventions.CASE SUMMARY A pregnant woman was admitted to the Department of Critical Care Medicine at the First Affiliated Hospital of Harbin Medical University due to consciousness disorders and drowsiness 2 h before admission.Subsequently,she developed vomiting and cyanotic skin.The woman underwent orotracheal intubation,invasive mechanical ventilation(IMV),and correction of internal environment disturbance in the ICU.Her premature infant was born with a higher-than-normal MetHb level of 3.3%,and received detoxification with methylene blue and vitamin C,supplemental vitamin K1,an infusion of fresh frozen plasma,as well as respiratory support via orotracheal intubation and IMV.On day 3 after admission,the puerpera regained consciousness,evacuated the IMV,and resumed enteral nutrition.She was then transferred to the maternity ward 24 h later.On day 7 after admission,the woman recovered and was discharged without any sequelae.CONCLUSION MetHb can cross through the placental barrier.Level of MetHb both reflects severity of the sodium nitrite poisoning and serves as feedback on therapeutic effectiveness.
文摘In the past 40 years,advances in neonatal intensive care unit(NICU)technology have enabled premature infants with lower birth weight and younger gestational age to survive.But with it comes an increase in the incidence of long-term respiratory dysfunction,mainly in the form of bronchopulmonary dysplasia(BPD).Preventing lung injury is crucial for preventing BPD and improving the long-term prognosis of premature infants.Therefore,how to avoid ventilator-associated lung injury has become a focus of clinical and scientific research in premature infants in recent years.This article will elaborate on the susceptibility and pathophysiology of premature infant lung injury,ventilation strategies for preventing lung injury,and new advances in neonatal respiratory support.

文摘BACKGROUND There have been few reports on level 3 difficult removal of peripherally inserted central catheter(PICC)in neonates.Here,we reported a case of an extremely preterm infant who underwent level 3 difficult removal of a PICC.CASE SUMMARY Female baby A,weighing 1070 g at 27^(+1) wk of gestational age,was diagnosed with extremely preterm infant and neonatal respiratory distress syndrome.She underwent PICC insertion twice.The first PICC insertion went well;the second PICC was inserted in the right lower extremity,however,phlebitis occurred on the second day after the placement.On the third day of catheterization,phlebitis was aggravated,while the right leg circumference increased by 2.5 cm.On the fourth day of catheterization,more red swelling was found in the popliteal part,covering an area of about 1.5 cm×4 cm,which was diagnosed as phlebitis level 3;thus,we decided to remove the PICC.During tube removal,the catheter rebounded and could not be pulled out(several conventional methods were performed).Finally,we successfully removed the PICC using a new approach termed“AFGP”.On the 36th day of admission,the baby fully recovered and was discharged.CONCLUSION The“AFGP”bundle approach was effective for an extremely preterm infant,who underwent level 3 difficult removal of a PICC.

文摘Background There is a paucity of studies conducted in China on the outcomes of all live-birth extremely premature infants(EPIs)and there is no unifed recommendation on the active treatment of the minimum gestational age in the feld of perinatal medicine in China.We aimed to investigate the current treatment situation of EPIs and to provide evidence for formulating reasonable treatment recommendations.Methods We established a real-world ambispective cohort study of all live births in delivery rooms with gestational age(GA)between 24+0 and 27+6 weeks from 2010 to 2019.Results Of the 1163 EPIs included in our study,241(20.7%)survived,while 849(73.0%)died in the delivery room and 73(6.3%)died in the neonatal intensive care unit.Among all included EPIs,862(74.1%)died from withholding or withdrawal of care.Regardless of stratifcation according to GA or birth weight,the proportion of total mortality attributable to withdrawal of care is high.For infants with the GA of 24 weeks,active treatment did not extend their survival time(P=0.224).The survival time without severe morbidity of the active treatment was signifcantly longer than that of withdrawing care for infants older than 25 weeks(P<0.001).Over time,the survival rate improved,and the withdrawal of care caused by socioeconomic factors and primary nonintervention were reduced signifcantly(P<0.001).Conclusions The mortality rate of EPIs is still high.Withdrawal of care is common for EPIs with smaller GA,especially in the delivery room.It is necessary to use a multi-center,large sample of real-world data to fnd the survival limit of active treatment based on our treatment capabilities.
文摘Objectives Growth retardation is a risk for premature infants.In addition to demographic and perinatal factors,preterm infants’physical growth may be affected by neonatal intensive care unit(NICU)stress,maternal postpartum depression,and mother-infant interaction.This study aimed to investigate the trajectories of physical growth in 4 months corrected age among preterm infants discharged from the NICU and the impactors on these trajectories.Methods A prospective study was conducted among 318 preterm infants from September 2019 to April 2021 in Shanghai,China.Latent growth modeling was applied to identify the weight,length,and head circumference growth trajectories in 4 months corrected age and explore the effects of demographic and medical characteristics,infant stress during NICU stay,maternal postpartum depression,and mother-infant interaction on each trajectory.Results Unconditional latent growth models showed curve trajectories with increasingly slower growth in weight,length,and head circumference until 4 months of corrected age.Conditional latent growth models showed that a longer length of stay in the NICU and more skin punctures were negatively associated with weight at 40 weeks corrected gestational age(β=−0.43 and−0.19,respectively,P<0.05).The maternal postpartum depression between 40 weeks corrected gestational age and 1 month corrected postnatal age was associated with a lower growth rate of length(β=−0.17,P=0.040),while between 2 and 3 months corrected postnatal age,there were lower growth rates of weight and head circumference(β=−0.15 and−0.19,respectively,P<0.05).The mother-infant interaction scores between 40 weeks corrected gestational age and 1 month corrected postnatal age negatively predicted the growth rate of weight(β=−0.19,P=0.020).Conclusion The physical growth trajectories of preterm infants discharged from the NICU were influenced by infant stress during the NICU stay,maternal postpartum depression and mother-infant interaction.

文摘AIM: To report the visual outcomes and refractive status in premature infants with and without retinopathy of prematurity(ROP) who were or not treated. METHODS: The clinical records of all premature infants with or without ROP and with or without treatment between 2007 and 2017 were retrospectively reviewed. Basic demographic data, serial changes in ROP incidence, treatment and outcomes, and the refractive states were analyzed. Correlations among myopia and astigmatism progression, birth weight, gestational age, and treatment methods were also analyzed.RESULTS: A total of 562 screened premature infants(all Chinese, 1124 eyes), were recruited with a 378:184 maleto-female ratio. Birth weight did not directly influence ROP incidence. The overall ROP incidence was 16.55%(93/562 cases). The incidences in boys and girls were 16.14%(33/378 cases) and 17.39%(32/184 cases), respectively, and this difference was not significant. However, all infants with serious ROP(stage IV and V) were male. Myopia combined with astigmatism was common in premature infants with and without ROP(30.99%, 172/555 cases), and myopic refraction(including myopia and myopia combined with astigmatism) was more common in premature infants with ROP(48.84%, 42/86 cases). In the >8.00 diopter group, there were significantly more ROP infants than without ROP. Myopic refraction(including myopia and myopia combined with astigmatism) was most common in infants with ROP after treatment(63.63%, 7/11 cases). CONCLUSION: The refractive state is different between premature infants and mature infants. Those treated for ROP had a higher chance of developing myopia, astigmatism, and higher diopter.

文摘Length and thickness of 152 corpus callosa Using ultrasonic diagnostic equipment with a were measured in neonates within 24 hours ot b^rtn. neonatal brain-specific probe, corpus callosum length and thickness of the genu, body, and splenium were measured on the standard mid-sagittal plane, and the anteroposterior diameter of the genu was measured in the coronal plane. Results showed that corpus callosum length as well as thickness of the genu and splenium increased with gesta- tional age and birth weight, while other measures did not. These three factors on the standard mid-sagittal plane are therefore likely to be suitable for real-time evaluation of corpus callosum de- velopment in premature infants using cranial ultrasound. Further analysis revealed that thickness of the body and splenium and the anteroposterior diameter of the genu were greater in male infants than in female infants, suggesting that there are sex differences in corpus callosum size during the neonatal period. A second set of measurements were taken from 40 premature infants whose ges- tational age was 34 weeks or less. Corpus callosum measurements were corrected to a gestational age of 40 weeks, and infants were grouped for analysis depending on the outcome of a neonatal behavioral neurological assessment. Compared with infants with a normal neurological assessment, corpus callosum length and genu and splenium thicknesses were less in those with abnormalities, indicating that corpus callosum growth in premature infants is associated with neurobehavioral development during the early extrauterine stage.
文摘Objective: Measure the effects of Early Intervention ad modum Katona (EI-K) in high-risk premature infants by means of clinical, neurobehavioral, and neurophysiologic tests. Method: We used the Amiel-Tison neurologic examination, the Bayley Scale of Infant Behavior, and electroencephalography (EEG) recordings at 42 weeks of conceptional age, and after 6 months of treatment EI-K (n = 14) and compared these results with those of a group of infants without early intervention (nEI) (n = 11). Results: We found better performance of infants in EI-K than nEI group after 6 months of treatment in neurologic and behavioral examination measurements, but found no differences in EEG comparisons. Conclusion: Our data suggest significant benefit of the use of EI-K program over n-EI in the neurologic and neurobe-havior examinations of premature infants after 6 months of age.
文摘Despite significant advances in perinatal medicine, the management of extremely preterm infants in the delivery room remains a challenge. There is an increasing evidence for improved outcomes regarding the resuscitation and stabilisation of extremely preterm infants but there is a lack of evidence in the periviable(gestational age 23-25 wk) preterm subgroup. Presence of an experienced team during the delivery of extremely preterm infant to improve outcome is reviewed. Adaptation from foetal to neonatal cardiorespiratory haemodynamics is dependent on establishing an optimal functional residual capacity in the extremely preterm infants, thus enabling adequate gas exchange. There is sufficient evidence for a gentle approach to stabilisation of these fragile infants in the delivery room. Evidence for antenatal steroids especially in the periviable infants, delayed cord clamping, strategies to establish optimal functional residual capacity, importance of temperature control and oxygenation in delivery room in extremely premature infants is reviewed in this article.
文摘To assess the efficacy and the optimum dose of recombinant human erythropoietin (rhEpo) on the anemia of premature, 45 preterm infants with a gestational age of less than 35 weeks and birth weight of less 1 800 g were randomly assigned to treatment group 1 (n = 15, receiving subcutaneous rhEpo 150 U/kg·time), treatment group 2 (n = 15, receiving 250 U/kg·time), three times a week for 6 weeks, and control group (n = 15, no treatment was given). All preterm infants received supplements of vitamin E (20 IU) and iron (20 mg) each day. Our results showed that postnatal decline of hemoglobin (Hb) and hematocrit (Hct) were lessened in the treatment groups, particularly in the group 2 and the differences were very significant (P<0. 0001 for all). Treated infants had significantly higher reticulocyte counts (Ret) (P<0. 000] for all), but there was no significant difference between the two treatment groups (P>0. 05). Serum iron dropped significantly in the treatment groups as compared with control group (P<0. 01 for all), but no dose-dependent relationship was observed in treated infants (P>0. 05). After treatment, serum levels of erythropoietin was higher in group 2 than those in group 1 and control group (P<0. 0001, P<0. 01 and P<0. 05, respectively). There was no significant difference between group 1 and control group (P>0. 05). No side effects related to rhEpo therapy were observed. Our study suggested that rhEpo therapy stimulates endogenous erythro-poiesis and enhances Ret, Hct and level of Hb in a dose-dependent manner in premature infants. The therapy is more efficient when given in higher dosages.

文摘Objectivs To evaluate the effect of phenobarbital in preventing intraventricular hemorrhage inpremature infants. Methods A randomized controlled trial for the prevention of neonatal intraventricularhemorrhage (IVH) was carried out in 57 Chinese premature infants with gestation of 34 weeks. These prematureinfants were randomly assigned to prevented (23 cases) or control (34 cases) groups. Results No statisticallysignificant differences in general data between the two groups were found. It was noticed that the average Apgarscore in prevented group was lower than that in the control group. The average age at the time of the loading dosesof phenobarbital was 8.9± 8.3 (0.5~25)h (outborn babies usually delay to receive phenobarbital), and the averageduration of the maintenance dose was 5d. The mean value of serum phenobarbital level obtained on day 4 was 20.9±5.2mg/L. The results demonstrated that the incidence of IVH and severe IVH decreased significantly inprevented group (74% vs 97%, P<0.05 and 13% vs 62%, P<0.01 respectively). NO severe IVH and hydrocephaluswere develOPed in the infants with IVH grade Ⅱ in the prevented group. While 7 infants with grade Ⅱ developedgrade Ⅲ during very short period, and 2 infants had to shunt for hydrocephalus in the control group. Infants onphenobarbital had not observed any side - effects. The duration of clinical symptoms was markedly shortened in theprevented group. Conclusion The study supports the use of phenobarbital for the prevention of IVH and severeIVH in Chinese premature infants. It is suggested that phenobarbital prophylaxis should be routinely carried outin all preterm infants with gestational age 34 weeks within 6h alter birth.

文摘Purpose: Pain assessment is a key component of good pain management in hospitalized infants.This study aimed to translate and adapt a version of pain measurement in infants,the Premature Infant Pain Profile Revised (PIPP-R) into Indonesian.Method: The adaptation process of the measuring instrument used a modified Brislin method which included forward translation,back translation 1,group discussion 1,back translation 2,group discussion 2,and pilot testing on neonatal nurses: feasibility test,inter-rater reliability using intraclass correlation (ICC),and internal consistency using Cronbach's α coefficient.Results: The PIPP-R version in English has been translated into Indonesian.In general,nurses assessed this measuring instrument as feasible.The inter-rater reliability showed a high agreement (ICC =0.968,P=0.001) and this measuring instrument had good internal consistency (Cronbach's α=0.856).Conclusion: The Indonesian version of PIPP-R is easy to use and shows good psychometric properties.The use of this measuring instrument will help nurses and researchers obtain accurate infant pain intensity measurement values.
文摘Premature infant is an infant who was born before the end of 37th weeks of pregnancy. Approximately 9.6% of infants are premature and they can be at risk for hospitalization. This study has done for evaluation of awareness and knowledge of parents about problems of premature infants in Neonatal Intensive Care Unit (NICU). This was a descriptive study with 160 parents whose premature infants were admitted to NICU (Tehran-Iran, 2009-2011). Data were collected by a questionnaire for evaluation of awareness and knowledge of parents about problems of prematurity, and then analyzed by using descriptive analytic statistical methods and SPSS software. Based on the results, there was a significant relation between age and the total score of questionnaire (P = 0.022, R = 0.18). Mothers had higher awareness and knowledge than fathers (P < 0.05). The most awareness in parents was about doing of hygienic principle when they entered to NICU and about the importance of regularly and continuous attendance in ward. Awareness and knowledge of parents about problems of their premature infant were related to their age and being a mother or father. Parents had little knowledge about some NICU principles and premature infant’s needs and care.
文摘Cytomegalovirus (CMV) infection is the most important cause of mental retardation and sensorineural hearing loss. Antiviral treatment with valganciclovir, a relatively new but potential toxic oral drug, is recommended to prevent further hearing deterioration. In this retrospective cohort study we evaluated the relation between the dose of valganciclovir and the reduction of CMV viral load, as well as the toxicity. All neonates with gestational
文摘Objective:To investigate predictors of caring behaviors of mothers of premature infants based on the health belief model.Methods:This cross-sectional study was conducted by using the structural equation modeling on 168 mothers of premature infants,who were selected by convenience sampling method from October 2017 to February 2018 in Iran.Data were collected by using a standard scale.Validity and reliability of all data collection tools were approved.Data were analyzed by using SPSS V.16 and Mplus6 software.Results:The structural equation modeling of the initial health belief model did not have a good fit,but the fitness of model 2 obtaining from the modified initial model was confirmed by changes in locations of constructs.None of constructs of model 2 had a significant positive association with the caring behavior of mothers of premature infants and only 2.8%of variance of caring behaviors in mothers could be predicted by the sum of variables of demographic characteristics and the modified health belief model constructs.Conclusions:Given that the findings do not approve the use of the health belief model in predicting determinants of caring behavior of mothers of premature infants,it is suggested to apply this model to investigate the effect of educational intervention based on the health belief model on the caring behavior of mothers.
文摘Background: Preterm birth is common in Morocco and it’s around 8%. Several management rules of taking care of preterm infants have been developed but have not been put into action. The geo-graphical inaccessibility to specialized hospitals and the weakness of the reception capacity of the care centers hinder the management of the complications associated with preterm birth. Purpose: The present study is designed to present some epidemiological data of preterm births within the Provincial Hospital Center of Missour during 2012 and to discuss the various problems emerging in the management of treatment and care. Materials and Methods: Retrospective study of preterm births in the maternity ward in the Hospital of Missour during 2012. Results: 37 preterm births among 1121 (3.3%) have been analyzed (51.3% severe premature infants, 45.9% late preterm infants and 2.7% extremely premature infants). 64.2% are originally from difficult areas to reach during winter. All mothers have received upon arrival at the maternity a corticosteroid and calcium antagonists (Adalate*) and an antibiotic treatment to those with a positive infectious anamnesis found in half of the women. We have recorded 3 twin pregnancies and 2 gravidic toxemias. Only 21 babies have been given back to their mothers (namely 56.7%). 5 premature infants (namely 13%) have been referred to the university hospital center of Fez (2 respiratory distress, a malformation and 2 severe premature births) given that there is an absence of a specialized care unit at the hospital, knowing that no baby has received neither surfactant nor caffeine at birth. 14 premature babies (namely 37.8%) have been transferred to the pediatric unit with a total death rate of 16.2% (6 premature) mainly related to neonatal infection and to suffering of the hyaline membranes disease. Conclusion: We emphasize the interest of prevention programs which demand an early diagnosis of preterm birth threats and monitoring high-risk pregnancies, improving the medical care given to low-weight premature by creating “Kangaroo” units at a regional level and the targeting of measures for rural and under-covered areas.

文摘[Objectives]To explore the efficacy of Danshen Injection combined with phosphocreatine disodium in treating frequent premature contractions during pregnancy and its effect on maternal and infant outcomes.[Methods]A total of 200 pregnant women with normal pregnancy and frequent premature contractions who were treated in the outpatient department of internal medicine in Women and Children's Hospital of Hubei Province and Xinzhou District People's Hospital of Wuhan Central Hospital during September 2015 and October 2018 were selected and randomly divided into the control group and observation group,100 cases for each group.The observation group was treated with Danshen Injection combined with phosphocreatine disodium,and the control group was treated with phosphocreatine disodium alone.The course of treatment in both groups was one week.During the treatment,the changes of heart rate,heart rhythm,electrocardiogram and 24-h dynamic electrocardiogram(DCG)of both groups were observed.[Results]After treatment,the clinical efficacy of the observation group was better than that of the control group,and the difference was statistically significant(P<0.01).There were no adverse drug reactions in both groups.However,in the control group,non-sustained ventricular tachycardia(NSVT)was found in 24-h dynamic electrocardiogram(DCG)of 2 pregnant women with premature ventricular contraction.The pregnancy process was smooth,with full-term natural delivery and no fetal malformation.There was no significant difference in gestational age and neonatal weight between the two groups(P>0.05).However,there was a statistically significant difference in Apgar score between the two groups(P<0.05).During the 6-month postpartum follow-up,the mother and child were unharmed,and examination of repeated electrocardiograms showed that the conditions were normal.[Conclusions]Danshen Injection combined with phosphocreatine disodium has better efficacy in the treatment of frequent premature contractions during pregnancy and the maternal and infant outcomes than the treatment with phosphocreatine disodium alone,and it has good safety and can prevent premature contractions from progressing to tachyarrhythmias.
文摘Objective: To systematically review the effect of Transitional Care model (TCM) on the growth and development of premature infants. Methods: Randomized controlled trials (RCTs) or quasi-RTCs regarding the effect of TCM in low birth weight premature infants were retrieved in electronic databases such as the Cochrane Library, PubMed, EMbase, Web of Science, CBM (Chinese Biomedicine Database), CNKI (China National Knowledge Infrastructure), VIP (Chinese Scientific Journals Database) and Wanfang Database. Then, we adopted RevMan 5.3 software to perform a meta-analysis. Results: A total of 11 articles were included, including 1282 preterm infants. The result showed that compared with the routine care model, TCM can effectively increase the weight when premature infants discharged one week [MD=225.57, 95%CI (171.78, 279.37), P<0.001], increase the weight after discharged one month [MD=0.89, 95%CI (0.72, 1.06), P<0.001], increase the weight after discharged three months [MD=670.44, 95%CI (527.65, 813.23), P<0.001], promote the height of newborns [MD=4.54, 95%CI (2.42, 6.65), P<0.001], reduce readmission rate [RR=0.38, 95%CI (0.25, 0.58), P<0.001], alleviate adverse skin reactions [RR=0.33, 95%CI (0.22, 0.50), P<0.001], increase nursing satisfaction of the families [RR=1.21, 95%CI (1.13, 1.31), P<0.001]. Conclusion: TCM can effectively promote the growth and development of the low birth weight premature infants, reduce the hospital readmission rate, alleviate adverse skin reactions of premature infants and improve the nursing satisfaction of the families. However, due to the limitation of the region and quality of the included studies, which the accuracy of the result still be treated with more caution. Further high-quality studies are needed to verify the conclusion.
