Group Ⅰ received preoperational anesthetic spary with 20 mL of 0.75% ropivacaine. Group Ⅱ was given the anesthetic ata same dosage after the operation. Group Ⅲ received preoperational anesthetic spary with 20 mL of 0.5% bupivacaine. Group Ⅳ received preoperational anesthetic spary with 20 mL saline. The LC was completed under general anesthesia.After the operation,visual analog scale (VAS)was recorded at 1,2,3 and 4 hours to evaluate the degree of postoperative pain.Meanwhile,the number of the patients who received anesthetics after the surgery,as well as the incidence rates shoulder or back pain and nausea or vomiting were recorded. Results: Postoperative VAS of the group Ⅱ was significantly lower than that of the other three groups, while the VAS of group Ⅲ was significantly lower than that in group Ⅰ(both Plt;0.05).Compared to groups Ⅰ, Ⅱ and Ⅲ,more patients in the group Ⅳ needed anesthetics after the operation (Plt;0.05).No significant diference was noticed in the incidence rates of shoulder or back pain and nausea or vomiting among the four groups (Pgt;0.05).Conclusions: Intraperitoneal local anesthetic can significantly reduce postoperative pain after LC. It is more effective to give local anesthetic at the end of the procedure than using it before operation. The effect of ropivacaine is better than bupivacaine.

  • Sevoflurane EC50 Values for the Removal of the Laryngeal Mask Airway in Children with Teracainum Gel

    摘要:目的:定量测定50 %小儿在喉罩表面涂抹丁卡因胶浆的情况下平稳拔除喉罩时呼气末七氟烷浓度。方法:25例择期行四肢及体表手术的患儿,高流量吸入七氟烷诱导并以七氟烷和氧化亚氮维持麻醉,不使用肌肉松弛剂及静脉麻醉药物,手术结束后停止吸入氧化亚氮,并维持设定的七氟烷浓度10min后拔除喉罩。根据Dixon序贯法确定喉罩拔除时的七氟烷浓度,每0.1 Vol%七氟烷为1个增减单位。患儿未出现咳嗽、牙关紧闭、体动、屏气及喉痉挛则认为拔除喉罩平稳。结果:50 %小儿平稳拔除喉罩时呼气末七氟烷浓度(EC50)为1.22 Vol%(95 %的置信区间分别为0.99 Vol%~1.49 Vol%)。结论:在喉罩表面涂抹丁卡因胶浆的情况下,3~8岁患儿喉罩满意拔除时呼气末七氟烷EC50值为1.22 Vol%。Abstract: Objective: To determine the concentration of sevoflurane where 50%( EC50 ) of the attempts to remove the laryngeal mask airway (LMA ) with the Teracainum Gel would be successful in children. Methods: Twentyfive nonpremedicated children, aged 38 years old, ASA physical status I, scheduled for extremities or peripherical surgery were enrolled in this study. General anesthesia was induced with sevoflurane and maintained with sevoflurane and nitrous oxide in oxygen. After the surgery, the target concentration was maintained for at least 10 min, and then the LMA was removed.  Each target concentration was predetermined by the Dixon’s upanddown method (with 0.1 Vol% as a step size), starting at 1.20 Vol% concentration of sevoflurane. A removal accomplished without coughing, teeth clenching, gross purposeful movement, breath holding or laryngospasm, during or within 1 min after removal was considered to be successful. Results:The concentration of sevoflurane to achieve successful LMA removal in 50% of children was 1.22 Vol% (95%CL, 0.99 Vol%1.49 Vol%). Conclusion: The EC50 value of sevoflurane for LMA smooth extubation in children aged 38 years old with teracainum gel was 1.22 Vol%.

  • Research status of lung transplantation and standardized management during transplantation period

    Lung transplantation is the only treatment for patients with end-stage lung diseases. And this field is also a research hotspot in the international field at presen. Relevant researches not only promote the progress and development of lung transplantation, but also improve the life quality of patients after transplantation. With the development of lung transplantation technology, the guidelines for identifying candidates are constantly being revised, and the source of donor lungs has always been an urgent problem for all transplantation centers. The standardized management during transplantation period involves anesthesia induction, intraoperative fluid management, airway management, management of important operative steps and postoperative pain management. Extracorporeal life support (ECLS) includes cardiopulmonary bypass (CPB) and extracorporeal membrane oxygenation (ECMO). With the progress and development of ECLS technology, the advantages of ECMO as a bridge for lung transplantation, intraoperative and postoperative circulatory support are becoming more and more prominent, enabling recipient patients to successfully pass the period of lung transplantation. Although lung transplantation in basic science and clinical researches has got a lot of progress, to improve the survival rate after transplantation, we must overcome many challenges including how to successfully perform lung transplantation, expand lung donor library, induce tolerance, and prevent complications after transplantation, primary graft dysfunction (PGD), cell and antibody mediated rejection and infection.

  • Association of anesthetics with postoperative delirium in patients undergoing cardiac surgery

    ObjectiveTo determine whether there was a clinical relevant association between anesthetic regimen (propofol or inhalational anesthetics) and the occurrence of postoperative delirium (POD) in patients undergoing cardiac surgery.MethodsThis retrospective study was conducted on patients with elective cardiac surgery under cardiopulmonary bypass (CPB) at West China Hospital of Sichuan University between October 2018 and March 2019. The patients were divided into a propofol group or an inhalational anesthetics group according to anesthetic regimen (including CPB). The primary outcome was the occurrence of POD during first 3 days after surgery. Logistic regression analysis was used to determine the relationship between anesthetic regimen and the occurrence of POD.ResultsA total of 197 patients who met the inclusion criteria were included, with an average age of 53 years, and 51.8% (102/197) were females. POD occurred in 21.3% (42/197) patients. The incidence of POD was 21.4% in the propofol group and 21.2% in the inhalational anesthetics group; there was no significant difference between the two groups (RR=1.01, 95%CI 0.51-2.00, P=0.970). Logistic regression analysis did not find that anesthetic regimen was a risk factor for delirium after cardiac surgery after adjusting risk factors (OR=1.05, 95%CI 0.48-2.32, P=0.900).ConclusionAnesthetic regimen (propofol or inhalational anesthetics) is not associated with an increased risk for POD in adult patients undergoing elective cardiac surgery under CPB.

  • Clinical advances on prevention of postoperative delirium during peri-anesthetic period

    Postoperative delirium (POD) is a serious postoperative complication, which is significantly correlated with poor prognosis such as prolonged hospital stay and increased rate of readmission. POD is the result of multiple factors, and intervention targeting at its risk factors can significantly reduce the incidence of POD. At present, POD prevention tends to be multidisciplinary and cluster-oriented, aiming at forming a process-oriented, whole-perioperative assessment and intervention path. However, at present, there are few studies on POD peri-anesthetic period intervention, and there are many controversies. All guidelines and expert consensus are also blank in this part, and further studies are needed to fill the gaps. This paper discusses the current prevention strategies for POD during peri-anesthetic period, guiding future studies and further improving the intervention strategies for POD during peri- anesthetic period, so as to reduce the occurrence of POD.

  • Association between anesthesia regimen and postoperative infection in patients undergoing cardiac surgery: A retrospective cohort study

    Objective To evaluate the association between anesthesia regimen (volatile or intravenous anesthetics) and postoperative infection in adult cardiac patients undergoing cardiac surgery. MethodsThe clinical data of 496 elective adults undergoing cardiac surgery under cardiopulmonary bypass from June 2019 to June 2020 in West China Hospital of Sichuan University were retrospectively analyzed, including 251 females and 245 males with an average age of 54.1±11.4 years. American Society of Anesthesiologists grade was Ⅰ-Ⅲ. There were 243 patients in a volatile group with sevoflurane or desflurane, and 253 patients in an intravenous anesthesia group with propofol. The primary outcome was the incidence of infection within 30 days after cardiac surgery, including pulmonary infection, surgical site infection, sepsis, and urinary tract infection. The secondary outcomes were duration of mechanical ventilation, incidence of reintubation, ICU stay, postoperative length of hospital stay and total hospitalization cost. Results A total of 155 (31.3%) patients developed postoperative infection within 30 days, with an incidence of 32.9% in the volatile group and 29.6% in the intravenous anesthesia group. There was no statistical difference in the incidence of infection (RR=1.111, 95%CI 0.855 to 1.442, P=0.431) or the secondary outcomes (P>0.05) between the two groups. Conclusion The anesthesia regimen (volatile or intravenous anesthetics) has no association with the risk of occurrence of postoperative infection in adult patients undergoing elective cardiac surgery with cardiopulmonary bypass.
