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.
ObjectiveTo investigate the effect of etomidate and propofol on inflammatory cytokines and cortisol for patients with lung adenocarcinoma.
MethodSixty patients scheduled for lung cancer surgery under general anesthesia were studied. All patients were randomly divided into an etomidate total intravenous anesthesia group (group E, 30 patients, 16 males and 14 females at age of 58.0±5.0 years) and a propofol total intravenous anesthesia group (group P, 30 patients, 17 males and 13 females at age of 55.0±5.0 years), with 30 patients in each group.
ResultsThe concentration of IL-6 in serum of patients in the two groups at time points T1, T2 and T3 was significantly higher than those at time point T0 (P < 0.01). The concentration of IL-10 and TNF-α in serum of patients at time points T1 and T2 was significantly higher than those at time point T0 (P < 0.01). And the difference of the concentration of TNF-α in serum of patients at time points T0 and T3 was not statistically significant (P > 0.05). The level of Cor of patients in the group E at time point T0 was slightly higher than those at time point T1, but lower than that at time points T2 and T3. There was no statistical difference in the concentration of IL-6 and TNF-α in serum of patients between the two groups. The level of IL-10 of patients in the group E at time points T2 and T3 was lower than those in the group P (P < 0.05), but no significant difference was observed at the other time points. The concentration of Cor in the patients in the group E at time point T1 was lower than that in the group P (P < 0.01), but no significant difference was observed either at the other time points.
ConclusionThe effect of etomidate used for maintenance of general anesthesia on the inflammatory factors is essentially similar to that of propofol.
ObjectiveTo summarize the management of anesthesia during robotic off-pump coronary artery bypass grafting (CABG) with the da Vinci surgical system in minimal thoractomy.
MethodsFrom May 2011 to December 2014, 24 patients (20 males and 4 females) at the average age of 62.1±12.8 years underwent robotic off-pump CABG with the da Vinci surgical system in our hospital. All the patients underwent the continuous invasive blood pressure monitoring, endotracheal intubation with the double-lumen tube after induction of general anesthesia, fiber bronchoscope positioning, intraoperative application of one-lung ventilation, placing the Swan-Ganz floating catheter, and monitoring the echocar-diography (TEE) and blood gas analysis and indexes of hemodynamics.
ResultsAll the patients were stable during the anesthesia induction period. There was no severe hypoxemia and hypercapnia. The surgery was successful and there was no thoracotomy. All the patients left off breathing machine postoperatively.The duration of mechanical ventilation was 5.3±2.8 hours. All patients were moved out from ICU in 18 hours.There was no thoracotomy for hemostasis after surgery. All the patients were discharged on the fourth or fifth day postoperatively. There was no death relevant to surgery or perioperative complications. There was no recurrence of cardiovascular events on the 30th day,3 months and 6 months postoperative follow-up.
ConclusionThis anesthesia method is safe and effective. It is a rapid recovery way with the fewer complications, less suffering of the patients, reliable anesthesia management and high satisfaction of the patients'.
Same-day surgery mode is an efficient medical mode, and the key point of its management is multidisciplinary collaboration optimization of the process and integration of enhanced recovery after surgery concept. This paper introduces the establishment of multidisciplinary collaboration system, clinical pathway maintenance, patient visit procedure optimization, preoperative and postoperative care and follow-up management of same-day surgery mode for children with strabismus correction under general anesthesia at West China Tianfu Hospital of Sichuan University, aiming to promote the further improvement of the pediatric same-day surgery process and provide a reference for the promotion of the pediatric same-day surgery mode.
Objective To systematically review the impacts of general anesthesia using sevoflurane versus propofol on the incidence of emergence agitation in pediatric patients. Methods Such databases as PubMed, EMbase, Web of Science, The Cochrane Library (Issue 4, 2012), CNKI, CBM, WanFang Data and VIP were electronically searched from inception to December 2012, for comprehensively collecting randomized controlled trials (RCTs) on the impacts of general anesthesia using sevoflurane versus propofol on the incidence of emergence agitation in pediatric patients. References of included studies were also retrieved. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of included studies. Then, meta-analysis was performed using RevMan 5.1 software. Results A total of 9 RCTs involving 692 children were included, of which, six were pooled in the meta-analysis. The results of meta-analysis showed that: a) after anesthesia induction using sevoflurane, intravenous propofol maintenance was associated with a lower incidence of emergence agitation compared with sevoflurane maintenance (RR=0.57, 95%CI 0.39 to 0.84, P=0.004); and b) patients anesthetized with total intravenous propofol had a lower incidence of emergence agitation compared with total inhalation of sevoflurane (RR=0.16, 95%CI 0.06 to 0.39, Plt;0.000 1). Conclusion The incidence of emergence agitation after general anesthesia using sevoflurane is higher than that using propofol. Due to the limited quantity and quality, the application of sevoflurane should be chosen based on full consideration into patients’ conditions in clinic.
Objective To explore anesthetic quality of epidural anesthesia with general anesthesia applied for surgery of rectal cancer. Methods One hundred and seventy-eight patients who were diagnosed as rectal cancer and received operation in the Central Hospital of Bazhong City from June 2010 to June 2012 were included retrospectively. These patients were divided into two groups according to the type of anesthesia， and the patients who received general anesthesia only were defined as group A， the patients who received epidural anesthesia with general anesthesia were defined as group B. The anesthetic quality and anesthetic adverse reaction were observed in two groups. Results The differences of baseline characteristics in two groups were not significant （P＞0.05）. The difference of anesthetic quality in two groups was not significant （P＞0.05）. In terms of anesthetic adverse reaction， the incidence rate of hypertension， hypotension，tachycardia， or postoperative nausea and vomiting of the group B was significantly lower than those of the group A （P＜0.05）. The incidence rate of bradycardia， premature ventricular contractions， or time of gastrointestinal function recovery had no significant differences （P＞0.05）. There was no nerve dysfunction of lower limb in two groups. Conclusion Epidural anesthesia with general anesthesia applied for surgery of rectal cancer as compared with general anesthesia only not only has the same anesthetic quality， but also has obvious advantages in decreasing anesthetic adverse reaction.
Day surgery has been applied in practice since more than 30 years ago in western world, which could obviously reduce the length of hospital stay, accelerate the recovery of patients, and achieve desirable economic and social benefits. Despite of the common development of day surgery in various diseases, the application of day surgery in breast general anesthesia surgery is limited. No related management standard has been established. By summarizing the experience of breast cancer day-surgery, Xijing Hospital of Air Force Medical University has established a comprehensive management standard, including preoperation, intraoperation, and postoperation management. Meanwhile, the nursing, resource allocation, follow-up, and stuff management are all enrolled into the management standard, aiming to improve the development of day surgery in general anesthesia breast cancer operation.
Objective To assess the influence of dexmedetomidine on the recovery of pediatric patients after sevoflurane anesthesia. Methods Such databases as PubMed (1966 to March 2012), The Cochrane Library (Issue 1, 2012), EBSCO (ASP) (1984 to March 2012), Journals@Ovid Full Text (1993 to March 2012), CBM (1978 to March 2012), CNKI (1979 to March 2012), VIP (1989 to March 2012), and WanFang Data (1998 to March 2012) were searched to collect randomized controlled trials (RCTs) about the influence of dexmedetomidine on the recovery of pediatric patients after sevoflurane anesthesia, and the references of the included studies were also retrieved. Two researchers extracted the data and evaluated the methodological quality of the included studies independently. Then the RevMan 5.2 software was used for meta-analysis. Results A total of 16 RCTs involving 1 217 patients were included. The results of meta-analysis showed that, compared with the placebo, dexmedetomidine could reduce the occurrence of emergence agitation (OR=0.18, 95%CI 0.13 to 0.25, Plt;0.000 01) and increase the occurrence of postoperative lethargy (OR=0.14, 95%CI 0.03 to 0.68, P=0.01), but there were no differences in the occurrence of side effects including bronchospasm, bucking, breathholding, and oxygen desaturation. Dexmedetomidine could also reduce mean arterial blood pressure (MAP) and heart rate (HR) of pediatric patients during the recovery period after sevoflurane anesthesia, but it increased emergence time (MD=2.14, 95%CI 0.95 to 3.33, P=0.000 4), extubation time (MD=1.26, 95%CI 0.51 to 2.00, P=0.000 9) and the time of staying in PACU (MD=4.72, 95%CI 2.07 to 7.38, P=0.000 5). Conclusions For pediatric patients recovering from sevoflurane-based general anesthesia, dexmedetomidine can reduce the occurrence of emergence agitation, and is helpful to maintain the hemodynamic balance. But it prolongs emergence time, extubation time (or the time of using the laryngeal mask) and the time of staying in PACU, and increases the occurrence of postoperative lethargy.
ObjectiveTo evaluate if intravenous lidocaine can reduce the stress response induced by fiberoptic bronchoscopy in patients under general anesthesia.
MethodsSixty patients undergoing fiberoptic bronchoscopy under unconsciousness between November 2013 and July 2014 were randomly divided into two groups: lidocaine group (n=30) and control group (n=30). Patients in the lidocaine group received an intravenous injection of lidocaine for 1 mg/kg during induction and then continuous intravenous infusion of 2% lidocaine with a dose of 3 mg/(kg·h). The same volume of saline was given to patients of the control group in the same way. Laryngeal mask airway was placed after anesthesia induction. Variables of heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure, and pulse oxygen saturation were observed and recorded at five time points: before induction, immediately after induction, immediately after laryngeal mask airway placement, fiberoptic bronchoscopy across tracheal carina and before leaving examination room. Complications including cough reflex, toxicity reaction of local anesthetics, and injection pain were also observed.
ResultsThe examination was successfully completed in all patients. Blood pressure and heart rate increased in all patients when fiberoptic bronchoscopy got across tracheal carina. There were no statistically significant differences in the two groups (P>0.05). Patients in the two groups had no statistic difference in tinnitus and numbness of tongue (P>0.05). Compared with the control group, patients in the lidocaine group had lower incidence of injection pain (P<0.05).
ConclusionIntravenous lidocaine cannot suppress stress response induced by fiberoptic bronchoscopy effectively.
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.
