Methods: Eighty patients who underwent thoracoscopic surgery in a tertiary hospital were selected as the study subjects and randomly divided into two groups, with 40 patients in each group. The control group received routine postoperative treatment with intravenous pain pump, while the experimental group received Parecoxib in addition to the standard postoperative pain pump treatment. Visual Analog Scale (VAS) pain scores were used to evaluate postoperative pain relief in both groups, along with adverse reactions, postoperative complications, and patient satisfaction with pain relief. Results: Patients who received Parecoxib injection in addition to the routine use of intravenous pain pump had VAS pain scores lower than 3 points at 6 h, 12 h, 24 h, and 36 h postoperatively compared to those in the control group. The incidence of postoperative lung collapse, pleural effusion, and pulmonary infections was also significantly lower in the experimental group. The differences between the two groups were statistically significant (P Conclusion: Early combined use of Parecoxib injection in the early postoperative period after thoracoscopic surgery has shown good clinical efficacy. It can reduce the level of pain in patients, promote effective coughing and expectoration, facilitate early mobilization of patients, improve patient compliance, reduce complications, shorten hospital stay, and expedite patient recovery. Therefore, it is worth promoting the widespread clinical application of Parecoxib injection in this setting.展开更多

Methods: Enrolled 60 nurses who took the IV infusion therapy training program in our hospital from January 2022 to December 2023 for research. 30 nurses who were trained in traditional teaching models from January to December 2022 were selected as the control group, and 30 nurses who were trained with simulation-based teaching models with methods including simulated patients, internet, online meetings which can be replayed and scenario simulation, etc. from January to December 2023 were selected as the experimental group. Evaluated the learning outcomes based on the Competency Inventory for Nursing Students (CINS), Problem-Solving Inventory (PSI), comprehensive learning ability, scientific research ability, and proficiency in the theoretical knowledge and practical skills of IV infusion therapy. Nursing quality, the incidence of IV infusion therapy complications and nurse satisfaction with different teaching models were also measured. Results: The scientific research ability, PSI scores, CINS scores, and comprehensive learning ability of the experimental group were better than those of the control group (P 0.05), and their assessment results of practical skills, nursing quality of IV infusion therapy during training, and satisfaction with teaching models were all better than those of the control group with statistical significance (P < 0.05). The incidence of IV infusion therapy complications in the experimental group was lower than that in the control group, indicating statistical significance (P < 0.05). Conclusions: Teaching models based on patient simulators combined with Internet Plus scenario simulation enable nursing students to learn more directly and practice at any time and in any place, and can improve their proficiency in IV infusion theoretical knowledge and skills (e.g. PICC catheterization), core competencies, problem-solving ability, comprehensive learning ability, scientific research ability and the ability to deal with complicated cases. Also, it helps provide high-quality nursing education, improve the nursing quality of IV therapy, reduce the incidence of related complications, and ensure the safety of patients with IV therapy.展开更多

However, the optimal timing and means of anticoagulation therapy remain unclear. OBJECTIVE: To observe the effects and safety of heparin treatment within 24 hours after intravenous thrombolysis for acute cerebral infarction. DESIGN: Observation experiment. SETTING: Department of Neurology, the 306 Hospital of Chinese PLA. PARTICIPANTS: Fifteen acute cerebral infarction patients complicated by moderate and severe neurologic function deficits within 6 hours after attack admitted to Department of Neurology, the 306 Hospital of Chinese PLA between January 2005 and December 2006 were recruited in this study. The involved patients, 11 male and 4 female, were aged 46- 79 years. They all met the diagnosis criteria for various cerebrovascular diseases formulated by the 4th National Conference for Cerebrovascular Disease (1995) and confirmed as cerebral infarction by skull CT or MRI imageology. Informed consents were obtained from the patients or their relatives. METHODS: On admission, patients received thrombolysis with urokinase. Immediately after thrombolysis, skull CT was rechecked. Intracranial hemorrhage signs were not found by skull CT. Hemorrhage was also not found in skin, mucous membrane and internal organs. Six hours later, low-dose low-intensity heparin 4 - 8 IU/kg per hour was intravenously administrated for anticoagulation for 7 - 10 days successively. MAIN OUTCOME MEASURES: Neurologic function was evaluated before, immediately 6 hours and 14 days after thrombolysis by scoring standard of clinical neurologic function deficit degree for stroke patients (1995). Activities of daily living of patients with stroke were evaluated 90 days after thrombolysis by modified Rankin Scale. RESULTS: Fifteen involved patients participated in the final analysis. ① Comparison of clinical neurologic function deficit degree of patients at different time: Neurologic function deficit score at the end of thrombolysis was significantly lower than that before thrombolysis (t =3.45, P 〈 0.01). Neurologic function deficit score 6 hours after thrombolysis was higher than that at the end of thrombolysis, and neurologic deficits were increased, but no significant difference was found (P 〉 0.05). Neurologic function deficit score 14 days after thrombolysis was significantly lower than that before thrombolysis (t =4.769, P 〈 0.01). ②Therapeutic effect and modified Rankin scale results: 14 days after thrombolysis, 4 patients were basically cured, 7 significantly improved, 2 improved and 2 worsened. The total improvement rate of neurologic function deficit was 86.7%. Ninety days after thrombolysis, according to modified Rankin Scale, score was 0 to 2 in 12 patients (80%), 3 to 4 in 2 patients (13.3%) and 6 in 1 patient (6.7%). Complications of intracranial hemorrhage were not found in patients within 14 days after thrombolysis. CONCLUSION: Low-dose and low-intensity heparin applied within 24 hours after intravenous thrombolysis has good safety and efficacy in the treatment of acute cerebral infarction.展开更多

Methods: A total of 176 patients with acute cerebral infarction who were treated in our hospital between September 2015 and February 2017 were reviewed and divided into the routine group (n=100 cases, receiving routine intravenous thrombolysis therapy) and the mild hypothermia group (n=76, receiving mild hypothermia + intravenous thrombolysis therapy), and the treatment lasted for 1 week. The differences in serum levels of nerve injury indexes, inflammatory mediators and neurotransmitters were compared between the two groups before treatment and after 1 week of treatment. Results: Before treatment, there was no statistically significant difference in serum levels of nerve injury indexes, inflammatory mediators and neurotransmitters between the two groups. After 1 week of treatment, serum nerve injury indexes H-FABP, NT-proBNP, NSE and S100B levels of mild hypothermia group were lower than those of routine group;inflammatory mediators sICAM-1, IL-8, IL-13 and IL-18 levels were lower than those of routine group;neurotransmitter Glu level was lower than that of routine group whereas GABA level was higher than that of routine group. Conclusion: mild hypothermia + intravenous thrombolysis therapy can effectively reduce the nerve injury and systemic inflammatory response, and optimize the neurotransmitter distribution in patients with acute cerebral infarction.展开更多

Methods: 92 patients with intracranial macrovascular infarction who received treatment in our hospital between February 2016 and January 2018 were selected as the research subjects and divided into the control group (n=46) and the study group (n=46) by random number table method. Control group received stent embolectomy alone, and study group received intravenous thrombolysis bridge stent combined with aspiration embolectomy. The differences in serum levels of inflammatory mediators, chemokines and nerve function-related indexes were compared between the two groups before treatment and 24h after embolectomy. Results: Before treatment, the differences in serum levels of inflammatory mediators, chemokines and nerve function-related indexes were not significant between the two groups. 24h after embolectomy, serum inflammatory mediators sICAM-1, hs-CRP and TNF-α levels of study group were lower than those of control group;serum chemokines CXCL16, Fractalkine and MCP-1 contents were lower than those of control group;serum nerve function-related indexes IGF-1, BDNF and CNTF levels were higher than those of control group whereas NSE level was lower than that of control group. Conclusion:Intravenous thrombolysis bridge stent combined with aspiration embolectomy can effectively reduce the systemic inflammatory response and optimize the nerve function in patients with intracranial macrovascular infarction.展开更多

Methods: A total of 886 patients who underwent painless endoscopic gastric polyp resection in the Department of Gastroenterology, the First Affiliated Hospital of Yangtze University, from January 2020 to December 2021, were selected as the study subjects. According to the random number table method, they were divided into an experimental group and a control group, with 443 cases in each group. Patients in the control group were subjected to routine fasting and water restriction for 8 hours before surgery, and routine fasting for 24 hours after surgery. Short-term intravenous nutrition support was provided through fluid supplementation, and finger blood glucose levels were monitored at 1 hour, 4 hours, and 8 hours after completion of intravenous infusion, or when symptoms such as palpitations and cold sweats occurred. The experimental group received oral administration of 5% glucose solution (500 ml) 2 hours before surgery based on the procedures of the control group. The incidence of preoperative discomfort (hunger, thirst, and fatigue), residual gastric fluid volume, and postoperative hypoglycemia were compared between the two groups. Results: The incidence of postoperative blood glucose Conclusion: Based on the study population, oral glucose combined with short-term intravenous nutrition can effectively prevent the incidence of hypoglycemia in patients undergoing painless endoscopic gastric polyp resection. However, due to the limitations of a single-center study and a small number of cases, its feasibility needs to be further validated with more data from multi-center and large-sample cases.展开更多

Methods: 860 patients who underwent endoscopic colorectal polypectomy for colorectal polyps in the Department of Gastroenterology of the First Affiliated Hospital of Yangtze University from January 2020 to December 2021 were selected for the study. The patients were divided into experimental and control groups according to the random number table method, with 430 patients in each group. In the control group, 3 L of polyethylene glycol electrolyte dispersion was used for preoperative intestinal preparation and postoperative fasting was performed routinely for 24 h. Short-term intravenous nutrition support was provided by rehydration, and finger blood glucose was monitored at 1, 4, and 8 h after intravenous infusion or when there were symptoms such as panic and cold sweat;in the experimental group, oral glucose intervention was implemented on the basis of the control group. The incidence of postoperative hypoglycemia, quality of bowel preparation, and tolerance of patients during bowel preparation were compared between the 2 groups.

文摘Objective:Discussion and analysis of the effect of the early application of Tirofiban on acute ischemic stroke(AIS)after intravenous thrombolysis with urokinase.Method:The subjects of this study are 40 patients with AIS admitted at the Yibin Fourth People’s Hospital,of which were computer-randomized into a control group(20 cases,with regular urokinase intravenous thrombolysis therapy)and a research group(20 cases,combined with early Tirofiban treatment)from January 2018 to December 2022.The intervention outcomes between these two groups were compared and analyzed.Result:The blood platelet-related parameters before treatment had no statistical difference between the two groups(P>0.05),but the research group was higher than that of the control group after treatment(P<0.05).The Barthel index before treatment in both groups had no statistical difference(P>0.05),but the research group was higher than that of the control group after treatment(P<0.05).Conclusion:Early Tirofiban treatment for patients with AIS after intravenous thrombolysis with urokinase could effectively regulate the blood platelet-related parameters,hence improving treatment benefits and living capacity for patients,with definite clinical benefits.
文摘BACKGROUND Left ventricular thrombus is a rare condition,for which appropriate treatments are not extensively studied.Although it can be treated by thrombectomy,such surgery can be difficult and risky,and not every patient can tolerate the surgery.CASE SUMMARY We report a case of a middle-aged man receiving veno-arterial extracorporeal membrane oxygenation(VA-ECMO)for acute myocardial infarction who developed left ventricular thrombus despite systemic anticoagulation.After systemic thrombolysis with urokinase,the left ventricular thrombus disappeared,ECMO was successfully withdrawn 9 days later,and the patient recovered and was discharged from hospital.CONCLUSION Systemic thrombolysis is a treatment option for left ventricular thrombus in addition to anticoagulation and thrombectomy.
文摘Objective: To explore the clinical effectiveness of combined use of intravenous pain pump with Parecoxib injection in alleviating pain in patients during the early postoperative period after thoracoscopic surgery. Methods: Eighty patients who underwent thoracoscopic surgery in a tertiary hospital were selected as the study subjects and randomly divided into two groups, with 40 patients in each group. The control group received routine postoperative treatment with intravenous pain pump, while the experimental group received Parecoxib in addition to the standard postoperative pain pump treatment. Visual Analog Scale (VAS) pain scores were used to evaluate postoperative pain relief in both groups, along with adverse reactions, postoperative complications, and patient satisfaction with pain relief. Results: Patients who received Parecoxib injection in addition to the routine use of intravenous pain pump had VAS pain scores lower than 3 points at 6 h, 12 h, 24 h, and 36 h postoperatively compared to those in the control group. The incidence of postoperative lung collapse, pleural effusion, and pulmonary infections was also significantly lower in the experimental group. The differences between the two groups were statistically significant (P Conclusion: Early combined use of Parecoxib injection in the early postoperative period after thoracoscopic surgery has shown good clinical efficacy. It can reduce the level of pain in patients, promote effective coughing and expectoration, facilitate early mobilization of patients, improve patient compliance, reduce complications, shorten hospital stay, and expedite patient recovery. Therefore, it is worth promoting the widespread clinical application of Parecoxib injection in this setting.
文摘Objective: To explore the effectiveness of applying patient simulators combined with Internet Plus scenario simulation teaching models on intravenous (IV) infusion nursing education, and to provide scientific evidence for the implementation of advanced teaching models in future nursing education. Methods: Enrolled 60 nurses who took the IV infusion therapy training program in our hospital from January 2022 to December 2023 for research. 30 nurses who were trained in traditional teaching models from January to December 2022 were selected as the control group, and 30 nurses who were trained with simulation-based teaching models with methods including simulated patients, internet, online meetings which can be replayed and scenario simulation, etc. from January to December 2023 were selected as the experimental group. Evaluated the learning outcomes based on the Competency Inventory for Nursing Students (CINS), Problem-Solving Inventory (PSI), comprehensive learning ability, scientific research ability, and proficiency in the theoretical knowledge and practical skills of IV infusion therapy. Nursing quality, the incidence of IV infusion therapy complications and nurse satisfaction with different teaching models were also measured. Results: The scientific research ability, PSI scores, CINS scores, and comprehensive learning ability of the experimental group were better than those of the control group (P 0.05), and their assessment results of practical skills, nursing quality of IV infusion therapy during training, and satisfaction with teaching models were all better than those of the control group with statistical significance (P < 0.05). The incidence of IV infusion therapy complications in the experimental group was lower than that in the control group, indicating statistical significance (P < 0.05). Conclusions: Teaching models based on patient simulators combined with Internet Plus scenario simulation enable nursing students to learn more directly and practice at any time and in any place, and can improve their proficiency in IV infusion theoretical knowledge and skills (e.g. PICC catheterization), core competencies, problem-solving ability, comprehensive learning ability, scientific research ability and the ability to deal with complicated cases. Also, it helps provide high-quality nursing education, improve the nursing quality of IV therapy, reduce the incidence of related complications, and ensure the safety of patients with IV therapy.

文摘BACKGROUND: Studies have demonstrated that immediate anticoagulation after thrombolysis can improve the prognosis of patients with acute cerebral infarction. However, the optimal timing and means of anticoagulation therapy remain unclear. OBJECTIVE: To observe the effects and safety of heparin treatment within 24 hours after intravenous thrombolysis for acute cerebral infarction. DESIGN: Observation experiment. SETTING: Department of Neurology, the 306 Hospital of Chinese PLA. PARTICIPANTS: Fifteen acute cerebral infarction patients complicated by moderate and severe neurologic function deficits within 6 hours after attack admitted to Department of Neurology, the 306 Hospital of Chinese PLA between January 2005 and December 2006 were recruited in this study. The involved patients, 11 male and 4 female, were aged 46- 79 years. They all met the diagnosis criteria for various cerebrovascular diseases formulated by the 4th National Conference for Cerebrovascular Disease (1995) and confirmed as cerebral infarction by skull CT or MRI imageology. Informed consents were obtained from the patients or their relatives. METHODS: On admission, patients received thrombolysis with urokinase. Immediately after thrombolysis, skull CT was rechecked. Intracranial hemorrhage signs were not found by skull CT. Hemorrhage was also not found in skin, mucous membrane and internal organs. Six hours later, low-dose low-intensity heparin 4 - 8 IU/kg per hour was intravenously administrated for anticoagulation for 7 - 10 days successively. MAIN OUTCOME MEASURES: Neurologic function was evaluated before, immediately 6 hours and 14 days after thrombolysis by scoring standard of clinical neurologic function deficit degree for stroke patients (1995). Activities of daily living of patients with stroke were evaluated 90 days after thrombolysis by modified Rankin Scale. RESULTS: Fifteen involved patients participated in the final analysis. ① Comparison of clinical neurologic function deficit degree of patients at different time: Neurologic function deficit score at the end of thrombolysis was significantly lower than that before thrombolysis (t =3.45, P 〈 0.01). Neurologic function deficit score 6 hours after thrombolysis was higher than that at the end of thrombolysis, and neurologic deficits were increased, but no significant difference was found (P 〉 0.05). Neurologic function deficit score 14 days after thrombolysis was significantly lower than that before thrombolysis (t =4.769, P 〈 0.01). ②Therapeutic effect and modified Rankin scale results: 14 days after thrombolysis, 4 patients were basically cured, 7 significantly improved, 2 improved and 2 worsened. The total improvement rate of neurologic function deficit was 86.7%. Ninety days after thrombolysis, according to modified Rankin Scale, score was 0 to 2 in 12 patients (80%), 3 to 4 in 2 patients (13.3%) and 6 in 1 patient (6.7%). Complications of intracranial hemorrhage were not found in patients within 14 days after thrombolysis. CONCLUSION: Low-dose and low-intensity heparin applied within 24 hours after intravenous thrombolysis has good safety and efficacy in the treatment of acute cerebral infarction.

文摘BACKGROUND The inferior vena cava filter is utilized worldwide to intercept thrombi and to reduce the risk of fatal pulmonary embolism(PE).However,filter-related thrombosis is a complication of filter implantation.Endovascular methods such as AngioJet rheolytic thrombectomy(ART)and catheter-directed thrombolysis(CDT)can treat filter-related caval thrombosis,but the clinical outcomes of both treatment modalities have not been determined.AIM To compare the treatment outcomes of AngioJet rheolytic thrombectomy vs catheter-directed thrombolysis in patients with filter-related caval thrombosis.METHODS In this single-center retrospective study,65 patients(34 males and 31 females;mean age:59.0±13.43 years)with intrafilter and inferior vena cava thrombosis were enrolled between January 2021 and August 2022.These patients were assigned to either the AngioJet group(n=44)or the CDT group(n=21).Clinical data and imaging information were collected.Evaluation measures included thrombus clearance rate,periprocedural complications,urokinase dosage,incidence of PE,limb circumference difference,length of stay,and filter removal rate.RESULTS Technical success rates were 100%in the AngioJet and CDT groups.In the AngioJet group,grade II and grade III thrombus clearance was achieved in 26(59.09%)and 14(31.82%)patients,respectively.In the CDT group,grade II and grade III thrombus clearance was accomplished in 11(52.38%)patients and 8(38.10%)patients,respectively(P>0.05).The peridiameter difference of the thigh was significantly reduced in patients from both groups after treatment(P<0.05).The median dosage of urokinase was 0.08(0.02,0.25)million U in the AngioJet group and 1.50(1.17,1.83)million U in the CDT group(P<0.05).Minor bleeding was shown in 4(19.05%)patients in the CDT group,and when it was compared with that in the AngioJet group,the difference was statistically significant(P<0.05).No major bleeding occurred.Seven(15.91%)patients in the AngioJet group had hemoglobinuria and 1(4.76%)patient in the CDT group had bacteremia.There were 8(18.18%)patients with PE in the AngioJet group and 4(19.05%)patients in the CDT group before the intervention(P>0.05).Computed tomography angiopulmonography(CTA)showed that PE was resolved after the intervention.New PE occurred in 4(9.09%)patients in the AngioJet group and in 2(9.52%)patients in the CDT group after theintervention(P>0.05).These cases of PE were asymptomatic.The mean length of stay was longer in the CDT group(11.67±5.34 d)than in the AngioJet group(10.64±3.52 d)(P<0.05).The filter was successfully retrieved in the first phase in 10(47.62%)patients in the CDT group and in 15(34.09%)patients in the AngioJet group(P>0.05).Cumulative removal was accomplished in 17(80.95%)out of 21 patients in the CDT group and in 42(95.45%)out of 44 patients in the ART group(P>0.05).The median indwelling time for patients with successful retrieval was 16(13139)d in the CDT group and 59(12231)d in the ART group(P>0.05).CONCLUSION Compared with catheter-directed thrombolysis,AngioJet rheolytic thrombectomy can achieve similar thrombus clearance effects,improve the filter retrieval rate,reduce the urokinase dosage and lower the risk of bleeding events in patients with filter-related caval thrombosis.
文摘Objective: To explore the efficacy of mild hypothermia + intravenous thrombolysis in promoting the neural functional recovery in patients with acute cerebral infarction. Methods: A total of 176 patients with acute cerebral infarction who were treated in our hospital between September 2015 and February 2017 were reviewed and divided into the routine group (n=100 cases, receiving routine intravenous thrombolysis therapy) and the mild hypothermia group (n=76, receiving mild hypothermia + intravenous thrombolysis therapy), and the treatment lasted for 1 week. The differences in serum levels of nerve injury indexes, inflammatory mediators and neurotransmitters were compared between the two groups before treatment and after 1 week of treatment. Results: Before treatment, there was no statistically significant difference in serum levels of nerve injury indexes, inflammatory mediators and neurotransmitters between the two groups. After 1 week of treatment, serum nerve injury indexes H-FABP, NT-proBNP, NSE and S100B levels of mild hypothermia group were lower than those of routine group;inflammatory mediators sICAM-1, IL-8, IL-13 and IL-18 levels were lower than those of routine group;neurotransmitter Glu level was lower than that of routine group whereas GABA level was higher than that of routine group. Conclusion: mild hypothermia + intravenous thrombolysis therapy can effectively reduce the nerve injury and systemic inflammatory response, and optimize the neurotransmitter distribution in patients with acute cerebral infarction.
文摘BACKGROUND Total shoulder arthroplasty(TSA)results in a large amount of perioperative blood loss due to severe trauma.AIM To investigate the safety and efficacy of intravenous tranexamic acid(TXA)in TSA.METHODS We searched the PubMed,Cochrane Library,Embase and Web of Science databases for randomized controlled trials(RCTs)on the use of TXA in TSA.And all the results were checked and assessed by Reference Citation Analysis(https://www.referencecitationanalysis.com/).A meta-analysis was performed with Review Manager 5.3 to calculate the odds ratio(OR)or weighted mean difference(WMD)of related outcome indicators.RESULTS A total of 5 RCTs with level 1 evidence were included.There were 369 cases,with 186 in the TXA group and 183 in the placebo group.The meta-analysis showed that TXA can significantly reduce total blood loss during the perioperative period[WMD=-249.56,95%confidence interval(CI):-347.6 to-151.52,P<0.0001],and the incidence of adverse reactions was low(OR=0.36,95%CI:0.16-0.83,P=0.02).Compared with the placebo group,the TXA group had significantly less total haemoglobin loss(WMD=-34.39,95%CI:-50.56 to-18.22),less haemoglobin fluctuation before and after the operation(WMD=-0.6,95%CI:-0.93 to-0.27)and less 24-h drain output(WMD=-136.87,95%CI:-165.87 to-106.49).There were no significant differences in the operation time(P=0.11)or hospital length of stay(P=0.30)between the two groups.CONCLUSION The application of intravenous TXA in the perioperative period of TSA can significantly reduce the total volume of perioperative blood loss and reduce the incidence of adverse reactions,so TXA is worthy of widespread clinical use.

文摘In oncolytic virus(OV)therapy,a critical component of tumor immunotherapy,viruses selectively infect,replicate within,and eventually destroy tumor cells.Simultaneously,this therapy activates immune responses and mobilizes immune cells,thereby eliminating residual or distant cancer cells.However,because of OVs’high immunogenicity and immune clearance during circulation,their clinical applications are currently limited to intratumoral injections,and their use is severely restricted.In recent years,numerous studies have used nanomaterials to modify OVs to decrease virulence and increase safety for intravenous injection.The most commonly used nanomaterials for modifying OVs are liposomes,polymers,and albumin,because of their biosafety,practicability,and effectiveness.The aim of this review is to summarize progress in the use of these nanomaterials in preclinical experiments to modify OVs and to discuss the challenges encountered from basic research to clinical application.

文摘BACKGROUND Implanted intravenous infusion port(TIAP)is mainly used for patients who need central venous infusion and poor peripheral vascular conditions.With the advantages of easy to carry,long maintenance cycle,few complications and excellent quality of life,it has been widely used in the fields of malignant tumor chemotherapy,parenteral nutrition support and repeated blood collection.Implanted intravenous infusion port(IVAP)dislocation can have significant complications if not recognised and reinstated immediately.CASE SUMMARY A 24-year-old man was treated with adjuvant chemotherapy for osteosarcoma.Severe displacement of IVAP catheter was found by chest X-ray examination.The IVAP cannot be used normally.Therefore,we conducted an emergency procedure to reset the catheter through double pigtail catheters,the operation was successful and the infusion port was restored.CONCLUSION When IVAP catheter displacement cannot be reset by conventional techniques,two pigtail catheters can be successfully used instead.
文摘Aim:This study aims to evaluate demands for general and pharmacological knowledge and training related to intravenous(IV)therapy among pediatric nurses.Materials and Methods:This multicentric cross‑sectional study involved 12,707 pediatric nurses from 100 hospitals in China.A questionnaire was used to assess information about IV drug administration training received,and the demands for pharmacology‑related knowledge,and corresponding methods of acquisition.A generalized linear model using Logit link function was employed to assess relationships between factors and multivariate analysis was conducted.Results:More than 99%of participants showed their training demands for IV therapy training.Pediatric nurses’demands and methods for acquiring IV therapy knowledge and the knowledge related to IV therapy pharmacology have significant differences in social demographic factors,previous knowledge,whether they have received training or not,and other factors(all P<0.05).Received a needlestick injury in the past month(P=0.007)and knowledge acquired through in‑hospital or out‑of‑hospital training(P=0.039)were factors that reduced the demands for methods to acquire further pharmacology‑related knowledge of IV therapy.Working in internal medicine(P=0.025)and not having experienced a needlestick injury in the past year(P=0.007)reduced the demands for IV therapy knowledge.Attended hospital(P=0.007)or departmental meetings(P=0.009),being pediatric primary nurses(P=0.044),and studied special IV guidelines(P=0.006)reduced the desire for methods to acquire IV therapy knowledge.Conclusion:There was a high demand for greater general and pharmacological knowledge related to IV therapy among pediatric nurses.Resources should be coordinated to provide ongoing training to nurses to improve the quality of IV care.
文摘Objective: To explore the application effect of oral glucose combined with short-term intravenous nutrition in preventing postoperative hypoglycemia after painless endoscopic gastric polyp resection, and to provide guidance for better management of patients undergoing such procedures. Methods: A total of 886 patients who underwent painless endoscopic gastric polyp resection in the Department of Gastroenterology, the First Affiliated Hospital of Yangtze University, from January 2020 to December 2021, were selected as the study subjects. According to the random number table method, they were divided into an experimental group and a control group, with 443 cases in each group. Patients in the control group were subjected to routine fasting and water restriction for 8 hours before surgery, and routine fasting for 24 hours after surgery. Short-term intravenous nutrition support was provided through fluid supplementation, and finger blood glucose levels were monitored at 1 hour, 4 hours, and 8 hours after completion of intravenous infusion, or when symptoms such as palpitations and cold sweats occurred. The experimental group received oral administration of 5% glucose solution (500 ml) 2 hours before surgery based on the procedures of the control group. The incidence of preoperative discomfort (hunger, thirst, and fatigue), residual gastric fluid volume, and postoperative hypoglycemia were compared between the two groups. Results: The incidence of postoperative blood glucose Conclusion: Based on the study population, oral glucose combined with short-term intravenous nutrition can effectively prevent the incidence of hypoglycemia in patients undergoing painless endoscopic gastric polyp resection. However, due to the limitations of a single-center study and a small number of cases, its feasibility needs to be further validated with more data from multi-center and large-sample cases.
文摘Objective: To investigate the effect of oral glucose combined with short-term intravenous nutrition on the prevention of hypoglycemia after endoscopic colorectal polypectomy and to provide guidance for better management of such patients. Methods: 860 patients who underwent endoscopic colorectal polypectomy for colorectal polyps in the Department of Gastroenterology of the First Affiliated Hospital of Yangtze University from January 2020 to December 2021 were selected for the study. The patients were divided into experimental and control groups according to the random number table method, with 430 patients in each group. In the control group, 3 L of polyethylene glycol electrolyte dispersion was used for preoperative intestinal preparation and postoperative fasting was performed routinely for 24 h. Short-term intravenous nutrition support was provided by rehydration, and finger blood glucose was monitored at 1, 4, and 8 h after intravenous infusion or when there were symptoms such as panic and cold sweat;in the experimental group, oral glucose intervention was implemented on the basis of the control group. The incidence of postoperative hypoglycemia, quality of bowel preparation, and tolerance of patients during bowel preparation were compared between the 2 groups. Results: The incidence of postoperative blood glucose Conclusion: Based on the present study population, oral glucose combined with short-term intravenous nutrition can effectively prevent the incidence of hypoglycemia in patients after endoscopic colorectal polypectomy;however, this was limited to a single-center study and the number of cases was small.
