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'.
Objective To investigate change of bispectral index(BIS) and hemodynamic index during induction and orotracheal intubation of sevoflurane anesthesia. Methods This study was a prospective before-after study in the same patients. A total of 30 ASA physical status I and II adult patients without airway abnormalities were enrolled to receive inhalation induction of anesthesia with 8% sevoflurane. Mean arterial pressure(MAP),heart rate(HR) and BIS were recorded before anesthesia(T1),when patients loss of consciousness(T2), before intubation (T3),at 1 min(T4) and 3 min(T5) after intubation. Results BIS at T1-T5 were 96.8±1.7,70.4±8.8,39.2±8.4,43.6±12.9 and 41.6±9.3 respectively, the measurements at T2-T5 were all markedly lower than at T1(Plt;0.05). HR at T3-T5 were all markedly higher than at T1(Plt;0.05). MAP at T2 and T3 were markedly lower than at T1, but at T4 was higher than at T1(Plt;0.05), and recovered to the level at T1 at T5(Pgt;0.05).BIS,HR and MAP at T4 were all significantly higher than T3(Plt;0.05). Conclusion Anesthesia induction with sevoflurane and small dose of succinylchoiline we used can provide adequate depth of general anesthesia,but can not prevent cardiovascular adverse reactions to intubation.
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 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.
Objective To systematically evaluate the effects of magnesium sulfate on postoperative pain and complications after general anesthesia. Methods A literature search was conducted in following databases as The Cochrane Library, EMbase, PubMed, EBSCO, Springer, Ovid, CNKI and CBM from the date of establishment to September 2011 to identify randomized controlled trials (RCTs) about intravenous infusion of magnesium sulfate during general anesthesia. All included RCTs were assessed and the data were extracted according to the standard of Cochrane systematic review. The homogenous studies were pooled using RevMan 5.1 software. Results A total of 11 RCTs involving 905 patients were included. The results of meta-analyses showed that compared with the control group, intravenous infusion of magnesium sulfate during general anesthesia significantly reduced the visual analog scale (VAS) scores at the time-points of 2, 4, 6, 8, 16, and 24 hours, respectively, after surgery, the postoperative 24 hours morphine requirements, and the incidents of postoperative nausea and vomiting (RR=0.61, 95%CI 0.40 to 0.91, P=0.02) and chilling (RR=0.29, 95%CI 0.14 to 0.59, P=0.000 7). Although the incidents of bradycardia (RR=1.93, 95%CI 1.05 to 3.53, P=0.03) increased, there were no adverse events or significant differences in the incidents of hypotension and serum concentration changes of magnesium. Conclusion Intravenous infusion of magnesium sulfate during general anesthesia may obviously decrease the pain intensity, and the incidents of nausea and vomiting and chilling after surgery, without increasing cardiovascular adverse events and risk of hypermagnesemia. The results still need to be confirmed by more high-quality and large-sample RCTs.
ObjectiveTo systematically review the protection effect of epidural anesthesia combined with general anesthesia versus general anesthesia alone in patients underwent cardiac surgery, so as to provide evidence for reducing complications of cardiac surgery. MethodsDatabases including PubMed, EMbase, The Cochrane Library (Issue 2, 2015), WanFang Data, CBM, and CNKI were searched to collect randomized controlled trials (RCTs) about epidural anesthesia combined with general anesthesia versus general anesthesia alone for patients underwent cardiac surgery from inception to February 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by RevMan 5.3 software. ResultsA total of 35 RCTs involving 3 311 patients were included. The results of meta-analysis showed that, compared with the general anesthesia group, the combination anesthesia group had lower incidence of supraventricular tachycardias (RR=0.63, 95%CI 0.48 to 0.83, P=0.001) and shorter ICU stay time (SMD=-0.57, 95%CI -1.02 to-0.12, P=0.01), but there were no significant differences in the incidences of respiratory complications, myocardial infarction, stroke and mortality between the two groups (all P values >0.05). ConclusionCurrent evidence shows that the combination of epidural anesthesia and general anesthesia has better protection effect than general anesthesia alone in cardiac surgery, but the influence on long-term prognosis still needs to be assessed. Due to the limited quality of included studies, the above conclusion still needs to be verified by more high quality studies．
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 determine the efficiency and safety of dexmedetomidine in general anesthesia. Methods Trials were located through electronic searches of the PubMed, EBSCO, OVID, Springer, Foreign Journals Integration System, CNKI, CMBdisk (from the date of establishment of the databases to April 2008). Bibliographies of the retrieved articles were also checked. Result A total of 25 trials involving 1 241 patients were included. The Meta-analysis showed: dexmedetomidine reduced peri-operative heart rate and blood pressure, reduced the occurrence of postoperative nausea and vomitting [RR=0.57, 95%CI (0.38, 0.84)], postoperative agitation [RR=0.29, 95%CI (0.17, 0.51)], shivering [RR=0.45, 95%CI (0.29, 0.68)], increase the occurrence of bradycardia [RR=2.16, 95%CI (1.58, 2.95)], hypotension [RR=2.97, 95%CI (1.42, 6.18)]. Dexmedetomidine reduced administration of thiopental, isoflurane and fentanyl, while there was no difference in muscle relaxant. Dexmedetomidine showed no difference in emergency time compared with the control group. As a result of low incidence of adverse reaction, dexmedetomidine showed superior in discharge time [WMD15.17, 95%CI (3.87, 26.46)]. Conclusions The limited current evidence shows that dexmedetomidine is better in maintaining the hemodynamic balance; reducing occurrence of nausea, vomiting, agitation and shivering; and reducing doses of anesthetics. In emergency time, dexmedetomidine shows no difference except discharge time.
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.
