Effects of combined spinal-epidural anesthesia on anxiety,labor analgesia and motor blocks in women during natural delivery

BACKGROUND The background of this study was analgesia in natural delivery.The combined spinal-epidural anesthesia has obvious analgesic effect on the parturients in natural labor,and combined spinal-epidural anesthesia has been widely used in anesthesia for various diseases.AIM To study the effects of combined spinal-epidural anesthesia on anxiety,labor analgesia,and motor blocks in parturients during natural delivery.METHODS A total of 120 women who gave birth at Changning District Maternal and Child Health Hospital between December 2021 to December 2022 were included;a random number table approach was employed to divide the women into a control group and a joint group,with each group consisting of 60 women.The control group was given epidural anesthesia,while the joint group was given combined spinal-epidural anesthesia.The visual analog scale(VAS)was used to evaluate the degree of maternal pain.Comparisons were made between the two groups’conditions of childbirth and the duration of labor.Apgar scores were used to evaluate the status of the newborns at birth;Self-rating Anxiety Scale(SAS)and General Self-Efficacy Scale(GSES)scores,umbilical artery blood gas analysis indices and stress indices were compared between the two groups;and the frequencies of motor block and postpartum complications were analyzed.RESULTS In comparison to the control group,in the joint group,the VAS scores for the first,second,and third stages of labor were lower(P<0.05).The rates of conversion to cesarean section and postpartum blood loss in the joint group were lower than those in the control group(P<0.05).No significant differences were observed in the Apgar score,the duration of the first stage of labor,or the total duration of labor between the two groups(P>0.05).The second and third stages of labor in the joint group were shorter than those in the control group(P<0.05).When compared to the control group,the postpartum SAS score of the joint group was lower,while the GSES score was greater(P<0.05).Between the control group and the joint group,the differences observed in pH,arterial carbon dioxide partial pressure,arterial oxygen partial pressure,or arterial hydrogen ion concentration were not significant(P>0.05).Nitric oxide,cortisol,and adrenaline levels were lower in the joint group than in the control group(P<0.05).There were no substantial differences in Bromage grade or rate of complications between the two groups(P>0.05).CONCLUSION For parturients during natural delivery,combined spinal-epidural anesthesia can reduce anxiety,provide labor analgesia,shorten labor time,and reduce postoperative stress levels but did not result in a motor block.

Efficacy of low-dose fentanyl and ropivacaine combined spinal-epidural anesthesia for labor analgesia

Objective: To study the efficacy of low-dose fentanyl and ropivacaine combined spinal-epidural anesthesia for labor analgesia. Methods: Puerperae who underwent vaginal delivery under combined spinal-epidural anesthesia for labor analgesia in Lincheng People's Hospital between June 2014 and March 2017 were selected and randomly divided into three groups, group A received 15 μg small-dose fentanyl and ropivacaine combined spinal-epidural anesthesia for labor analgesia, group B received 25 μg large-dose fentanyl and ropivacaine combined spinal-epidural anesthesia for labor analgesia, and group C received ropivacaine epidural anesthesia alone for labor analgesia. During delivery, the serum in the second stage of labor was collected to determine the contents of pain transmitters, inflammatory cytokines and stress response indexes. Results: During delivery, serum SP, 5-HT, DA, NE, DYN, TNF-α, IL-1β, IL-6, IL-10, PGE2, Cor, C-P, MDA and AOPP contents of group A and group B were lower than those of group C and serum SP, 5-HT, DA, NE, DYN, TNF-α, IL-1β, IL-6, IL-10, PGE2, Cor, C-P, MDA and AOPP contents of group A were not significantly different from those of group B. Conclusion: 15 μg small-dose fentanyl and ropivacaine combined spinal-epidural anesthesia for labor analgesia is with exact efficacy and good safety.

Effects of Combined Spinal Epidural Anaesthesia and Spinal Anaesthesia on Peri-Operative Pulmonary Status in Geriatric Patients in Lower Extremity Surgery

Background: Lower extremity surgeries performed in elderly people usually have high prevalence of peri-operative medical problems related to anaesthesia. The overall objective of peri-operative care of geriatric population is to fast recovery from anaesthesia and avoid functional decline. Objective: To compare the peri-operative pulmonary status of combined spinal epidural anaesthesia (CSEA) and spinal anaesthesia (SA) in geriatric patients underwent lower extremity surgeries. Methods: This prospective comparative study was conducted at Department of Anaesthesia, Analgesia and Intensive Care Medicine, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from July 2016 to June 2018. A total of 70 geriatric cases that underwent lower extremity surgeries were included in this study. Cases were randomly allocated into two groups;35 in Group A (CSEA) and 35 in Group B (SAB). The different outcome variables between the groups like-duration of anaesthesia, respiratory rates (RR), oxygen saturation (SpO2), end tidal CO2 (EtCO2), peak expiratory flow rate (PEFR), breath holding test (BHT), peri-operative side effects of anaesthesia and post-operative visual analogue score (VAS) were analyzed and compared by statistical tests. Results: The mean age, weight, BMI of Group A and Group B patients were not significantly different (p > 0.05). No significant differences were observed in duration of surgery, gender and ASA grade between the groups (p > 0.05). Mean duration of anaesthesia, mean time to achieve target level of sensory block and mean time to achieve complete motor block were significantly higher in Group A (p < 0.001). Mean RR, SpO2, EtCO2, PEFR and BHT of both groups were not significantly different (p > 0.05). Peri-operative side effects of anaesthesia and post-operative VAS were significantly less in group A patients (p < 0.05). Conclusion: Combined spinal epidural anaesthesia is effective and safe;produces stable peri-operative pulmonary status with prolonging analgesia and fewer side effects as compared to spinal anaesthesia in geriatric patients.

Cardiopulmonary,Biochemical and Haematological Effects of the Tiletamine/Zolazepam-Xylazine-Tramadol Combination to Provide Anaesthesia in Miniature Pigs

The objective of this study was to investigate the suitability of tiletamine/zolazepam-xylazine-tramadol combination for miniature pigs. Fourteen Chinese experimental miniature pigs subjected to this study received 3.5 mg tiletamine/zolazepam kg-1 bw, 1.32 mg xylazine kg-1 bw and 1.8 mg tramadol kg-1 bw intramuscularly, as a mixture of the drugs. Cardiopulmonary, biochemical and haematological parameters were recorded before drug administration and after anaesthesia. The combination of the compounds resulted in anaesthesia lasting about 87 min and a satisfactory immobilization for handling. Cardiopulmonary parameters were changed after administration, but there were within biologically acceptable limits. Biochemical and haematological values decreased after drug administration, however, they returned to the baseline at 24 h. At the doses described, tiletamine/zolazepam-xylazine-tramadol combination produced good immobilization in miniature pigs with minimal changes over time in cardiopulmonary, biochemical and haematological parameters.

目的探讨球后麻醉、球周麻醉、结膜下浸润麻醉3种麻醉方式联合表面麻醉在眼球摘除及眼胎植入术中运用的效果。方法 106例眼球不能保留、需作眼内容物剜除(眼球摘除)及眼胎植入术的患者,随机分为A组和B组:A组53例采用球后麻醉、球周麻醉、结膜下浸润麻醉联合表面麻醉;B组53例采用单纯球后麻醉。结果1)A组53例平均麻醉起效时间为181.21s;B组53例平均麻醉起效时间为467.32s,两组间比较差异有统计学意义(P<0.05);2)A组术中和术后有8例出现疼痛症状,B组术中和术后有22例出现疼痛症状,两组间比较差异有统计学意义(P<0.05);3)A组平均镇痛持续时间200.68min;B组平均镇痛持续时间145.34min,两组间比较差异有统计学意义(P<0.05)。结论与单纯球后麻醉相比,球后麻醉、球周麻醉、结膜下浸润麻醉联合表面麻醉在眼球摘除及眼胎植入术中具有起效快、镇痛效果好、镇痛时间长的优点。

曲马多静脉自控给药与腰硬联合阻滞用于分娩镇痛的比较

目的探讨曲马多实施静脉分娩镇痛的临床可行性和安全性。方法选择2011年3月~2012年6月北京妇产医院住院分娩的产妇75例,产妇均为单胎,足月妊娠。随机分成PCIA(曲马多静脉镇痛)组、PCEA(椎管内镇痛)组和对照组,每组25例。PCIA以及PCEA组产妇出现规律宫缩、宫口>3 cm时PCIA组静脉给予1.5 mg/kg曲马多注射液缓慢滴注,连接电子泵,患者自控镇痛(PCA)剂量2 m L,锁定时间10 min;PCEA组行L2~3间隙腰硬联合穿刺,鞘内注射3 mg罗哌卡因,硬膜外置管连接电子泵,PCA剂量5 m L,锁定时间10 min。对照组产妇不给予任何镇痛干预。观察三组产妇生命体征、镇痛效果、产程变化以及不良反应发生情况。结果 PCEA组的产妇在镇痛后5、15 min时血压与镇痛前相比下降明显,差异有统计学意义(P<0.05)。PCIA组仅在15 min时,血压有轻度下降,但差异无统计学意义(P>0.05)。三组产妇实施镇痛前视觉模拟评分(VAS)比较差异无统计学意义,镇痛后PCEA组VAS评分明显低于PCIA组和对照组(P<0.05),对照组VAS评分高于PCIA组(P<0.05)。PCEA组产妇第二产程相对于其他两组均有所延长(P<0.05);PCEA组和对照组新生儿出生1 min后Apgar评分高于PCIA组,差异均有统计学意义(P<0.05)。三组新生儿体重比较差异无统计学意义(P>0.05)。对照组剖宫产例数明显高于分娩镇痛组,三组比较差异有统计学意义(P<0.05);PCIA组催产素使用例数低于PCEA组和对照组(P<0.05);PCIA组产妇不良反应主要有出汗、恶心、呕吐,PCEA组产妇不良反应主要有皮肤瘙痒和尿潴留,三组产妇不良反应发生情况比较,差异无统计学意义(P>0.05)。结论椎管内分娩镇痛可安全、有效地用于分娩镇痛,应作为临床主要应用的方法。曲马多可以安全、有效应用于临床分娩镇痛,可作为椎管内分娩镇痛的有益的补充方法。
