目的:观察依托咪酯持续输注用于麻醉诱导和维持对肾上腺皮质功能的抑制程度以及评价是否会造成严重不良后果。方法:择期行普外手术患者60例,随机分成依托咪酯组(E组)和异丙酚组(P组)。两组患者常规麻醉诱导后,E组和P组分别采用瑞芬太尼0.1～0.4 μg/kg·min,复合依托咪酯或异丙酚维持,据BIS值调整依托咪酯或异丙酚的输注速率。分别测定麻醉前,手术结束时,术后24 h,术后48 h患者血清皮质醇浓度,记录各组的血压,心率,睁眼时间,拔管时间和术后不良反应。结果:与麻醉前比较,E组和P组患者在手术结束时皮质醇浓度均降低,但E组降低更明显(Plt;0.05),48 h后恢复正常甚至高于麻醉前水平;与诱导前相比,异丙酚组患者诱导后平均动脉压(MAP)明显低于诱导前,而依托咪酯组无明显变化;E组的拔管时间比P组长(Plt;0.05),而睁眼时间无明显差异(Pgt;0.05).结论:1依托咪酯和异丙酚均能抑制患者肾上腺皮质功能,且依托咪酯组更为明显,在术后48 h基本恢复正常,甚至高于术前水平。2依托咪酯在麻醉诱导和维持中比异丙酚具有血流动力学稳定性。3依托咪酯持续输注用于全身麻醉维持并不造成围术期严重不良后果。
Objective To evaluate the effect of intraoperative fluid infusion volume on postoperative pulmonary complications (PPCs) in patients after minimally invasive endoscopic esophageal carcinoma resection. Methods From June 2019 to August 2021, 486 patients undergoing elective minimally invasive endoscopic esophagectomy for esophageal cancer were retrospectively screened from the electronic medical record information management system and anesthesia surgery clinical information system of West China Hospital of Sichuan University. There were 381 males and 105 females, with a median age of 64.0 years. Taking the incidence of pulmonary complications within 7 days after operation as the primary outcome, the correlation between intraoperative fluid infusion volume and the occurrence of PPCs within 7 days was clearly analyzed by regression analysis. ResultsThe incidence of pulmonary complications within 7 days after surgery was 33.5% (163/486). Regression analysis showed that intraoperative fluid infusion volume was correlated with the occurrence of PPCs [adjusted OR=1.089, 95%CI (1.012, 1.172), P=0.023], especially pulmonary infection [adjusted OR=1.093, 95%CI (1.014, 1.178), P=0.020], and pleural effusion [adjusted OR=1.147, 95%CI (1.007, 1.306), P=0.039]. Pulmonary infection was significantly less in the low intraoperative fluid infusion group [<6.49 mL/(kg·h), n=115] compared with the high intraoperative fluid infusion group [≥6.49 mL/(kg·h), n=371] (18.3% vs. 34.5%, P=0.023). Intraoperative fluid infusion volume was positively associated with death within 30 days after surgery [adjusted OR=1.442, 95%CI (1.056, 1.968), P=0.021]. Conclusion Among patients undergoing elective minimally invasive endoscopic esophageal cancer resection, intraoperative fluid infusion volume is related with the occurrence of PPCs within 7 days after the surgery, especially pulmonary infection and pleural effusion, and may affect death within 30 days after the surgery.

ObjectiveTo systematically review the efficacy and safety of extended or continuous intravenous infusion (EI/CI) versus short-term intravenous infusion (STI) of imipenem/meropenem in adult patients with severe lung infection. MethodsWe electronically searched databases including PubMed, EMbase, The Cochrane Library (Issue 6, 2015) and CBM from inception to June, 2015, to collect random controlled trials (RCTs) about EI/CI versus STI of imipenem/meropenem for severe infection. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.2 software. ResultsA total of 6 RCTs involving 442 patients were included. The results of meta-analysis showed that, compared with the STI group, the EI/CI could significantly improve the microbiological success rate (RR=1.16, 95%CI 1.02 to 1.32, P=0.02) without increasing adverse drug reaction (RR=0.99, 95%CI 0.65 to 1.52, P=0.97). There were no significant differences in clinical effective rate (RR=1.12, 95%CI 0.97 to 1.28, P=0.13), survival rate (RR=1.03, 95%CI 0.92 to 1.16, P=0.62) and hospital stays (MD=-0.43, 95%CI-1.29 to 0.42, P=0.32) between the two groups. Conclusions There is no significant difference in clinical effect between EI/CI and STI for severe lung infection. While, the infections caused by gram-negative bacteria with high MIC could benefit more from EI/CI. Due to the limited quantity and quality of the included studies, the above conclusion still need to be further verified by more high quality studies.
ObjectiveTo investigate the effect of pulsed colloid infusion combined with continuous blood purification (CBP) for treatment of severe capillary leak syndrome (CLS). MethodsAccording to random principle,61 patients were divided into a control group(n=21),a CBP1 group(n=18) and a CBP2 group(n=22). All patients of three groups received routine treatment according to international guidelines 2008 for management of severe sepsis. The patients in the control group also received pulsed infusion colloid combined lasix. The patients in the CBP1 and CBP2 groups also received continuous veno-venous hemofiltration(CVVH) for 72 hours. The patients in the CBP1 group received concentrated colloid infusion combined lasix,and the patients in the CBP2 group received concentrated colloid infusion combined removing fluid. Blood gas analysis and Impedance Cardiography was performed before and 24,48 and 72 hours after therapy. The angiopoietin-2(Ang-2) was measured. Also the length of ICU stay,duration of mechanical ventilation,and death rate of patients in 28 days were observed. ResultsCompared with the control group and the CBP1 group,the length of ICU stay(days) and duration of mechanical ventilation (days) in the CBP2 group were significantly shorter(P<0.05),and the death rate in 28 days was lower(P<0.05). The patients in the CBP2 group showed more reduction in the APACHEⅡ score compared with the CBP1 group after therapy(P<0.05). The oxygenation index in the CBP2 group respectively increased at 24,48 and 72 hours after therapy(P<0.05). Compared with the control group and the CBP1 group,the oxygenation index in the CBP2 group respectively increased at the same time(P<0.05). The thoracic fluid content (TFC) in the CBP2 group respectively decreased at 24,48 and 72 hours(P<0.05) after therapy,and decreased compared with the control group and the CBP1 group at the same time(P<0.05). The serum levels of Ang-2 in the CBP2 group respectively decreased at 24,48 and 72 hours after therapy(P<0.05),and decreased compared with the control group and the CBP1 group at the same time(P<0.05). ConclusionPulsed colloid infusion combined with continuous blood purification can reduce the severity of capillary leak and improves the outcome of patients with severe sepsis.

ObjectiveTo understand the adverse effects of perioperative red blood cells (RBC) transfusion on patients after pancreaticoduodenectomy (PD) so as to provide ideas for reducing postoperative complications and improving prognosis. MethodThe relevant literatures at home and abroad in recent years about studies of perioperative RBC transfusion on postoperative complications (focusing on pancreatic fistula and infection) and prognosis of patients with PD were reviewed. ResultsThe rates of postoperative complications and perioperative RBC transfusion after PD were still higher. The perioperative RBC transfusion might increase the rate of postoperative complications, promote early tumor recurrence, and shorten the disease-free survival and overall survival. At present, with the progress of technology, the perioperative RBC transfusion rate was decreasing. At the same time, with the accelerated development of new blood transfusion technologies such as freeze-drying and refrigeration, the decline rate was still expected to be increased. ConclusionsPerioperative RBC transfusion in PD might have adverse effects on postoperative complications and prognosis. Although further research is still needed to explore its necessary connection, this adverse effect needs to be paid enough attention in clinical practice. Early identification of risk factors, strict transfusion indications and minimizing amount or concentration of RBC transfusion might help to avoid or reduce RBC transfusion and minimize its adverse effects.
