ObjectiveTo explore the risk factors for death within 7 days after admission in trauma patients undergoing surgery under general anesthesia, and provide evidence for predicting the outcomes of those patients and guidance for clinical practices.MethodsThe basic information and perioperative data of trauma patients who underwent surgery under general anesthesia between January 1st 2019 and December 31st 2020 were collected from the Hospital Information System and the Anesthesia Information Management System. Patients who died within 7 days after admission were assigned into the case group and the others were assigned into the control group, and then propensity-score matching method was used based on age, sex, and injury types. Univariate analyses and multivariate binary logistic regression analysis were used to identify the risk factors for death within 7 days after admission in these patients.ResultsThere were 2 532 patients who met the inclusion criteria, of whom 96 patients with missing follow-up information were excluded, and 2 436 patients remained for the study. After propensity-score matching, there were 19 patients in the case group and 95 patients in the control group. The result of multivariate logistic regression analysis showed that the coma state at admission [odds ratio (OR)=9.961, 95% confidence interval (CI) (1.352, 73.363), P=0.024], perioperative body temperature<36℃ [OR=23.052, 95%CI (1.523, 348.897), P=0.024], intraoperative mean arterial pressure<60 mm Hg (1 mm Hg=0.133 kPa) [OR=12.158, 95%CI (1.764, 83.813), P=0.011], serum calcium concentraion<2.0 mmol/L [OR=33.853, 95%CI (2.530, 452.963), P=0.008], and prothrombin time [OR=1.048, 95%CI (1.002, 1.096), P=0.042] increased the risk of death within 7 days after admission.ConclusionThe coma state, coagulopathy, perioperative hypothermia, intraoperative hypotension, and hypocalcemia are 5 independent risk factors for death in trauma patients after surgery under general anesthesia.
ObjectivesTo systematically review the efficacy of lidocaine injected prior to tracheal extubation in preventing hemodynamic responses to tracheal extubation in general anesthesia.MethodsPubMed, Ovid, Web of Science, EMbase, The Cochrane Library, CBM, CNKI, VIP and WanFang Data databases were electronically searched to collect randomized controlled trials (RCTs) on the efficacy of lidocaine administrated prior to extubation in preventing hemodynamic responses to tracheal extubation in patients undergoing general anesthesia from inception to October, 2018. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 and Stata 13.0 software.ResultsA total of 10 RCTs involving 525 patients were included. The results of meta-analysis showed that: compared with control group, lidocaine could reduce mean arterial pressure in 5 min after extubation (MD=–5.10, 95%CI –9.41 to –0.79, P=0.02), weaken the increase in systolic blood pressure caused by extubation from the moment before extubation to 5 minutes after extubation (before extubation: MD=–7.22, 95%CI –10.34 to –4.11, P<0.000 01; at extubation: MD=–14.02, 95%CI –19.42 to –8.62, P<0.000 01; 1 minutes after extubation: MD=–15.82, 95%CI –22.20 to –9.45, P<0.000 01; 3 minutes after extubation: MD=–12.55, 95%CI –20.36 to –4.74, P=0.002; and 5 minutes after extubation: MD=–12.05, 95%CI –20.35 to –3.74, P=0.004), and weakened extubation-induced increase in diastolic blood pressure at extubation (MD=–9.71, 95%CI –16.57 to –2.86, P=0.005). In addition, lidocaine inhibited heart rate in all time points except the moment of before and at 10 minutes after extubation.ConclusionsCurrent evidence shows that lidocaine can inhibit the increase in blood pressure and heart rate caused by extubation at certain times. Due to limited quality and quantity of the included studies, more high-quality studies are needed to verify above conclusions.
