Objectives To investigate the association of anesthesia recovery time and bispectral index (BIS) monitoring after gastrointestinal surgeries under general anesthesia. Methods A total of 404 cases of selective gastrointestinal surgeries under general anesthesia with BIS monitoring in West China Hospital of Sichuan University from January 2016 to June 2016 were retrieved from anesthesia medical record system as BIS monitoring exposure cohort (group BIS). In addition, 404 cases of selective gastrointestinal surgeries without BIS monitoring were matched as none BIS monitoring exposure cohort (group non-BIS). The primary outcome was the anesthesia recovery time, including the time from the end of surgery to endotracheal extubation (t1) and exiting the operation room (t2). A sub-group analysis was conducted based on patients’ age, length of operation time (t0) and type of surgery(open surgeries vs laparoscopic surgeries). Results The gender, age, body weight and ASA categories between two groups had no significant differences (P>0.05). The length of operation time also had no significant differences between two groups (P>0.05). The extubation time (10.1±4.4vs. 16.4±6.8) and OR exiting time (21.7±12.3 vs. 27.4±14.6) in group BIS were shorter than those in group non-BIS (P<0.05). This difference was markedly significant among elderly patients (age>60) or patients undergoing long operations (operation time>5hours). Among each group, the recovery time had no significant difference between open surgeries and laparoscopic surgeries. Conclusions There is an association between BIS monitoring and shorter anesthesia recovery time in gastrointestinal surgery, including the time of endotracheal extubation and exiting the operation room. BIS monitoring enhances anesthesia recovery among elderly patients and patients undergoing long-lasting operations in particular. There is no significant difference in anesthesia recovery time between open surgeries and laparoscopic surgeries.
Objective To research anesthetic management, pathophysiologic variation of adult-to-adult living donor liver transplantation (A-ALDLT) and to probe how to improve anesthetic quality of A-ALDLT. Methods The clinical data of 47 donors from Sep. 2005 to Jan. 2007 in West China Hospital were reviewed. Intraoperative vital signs, anesthetic management, perioperative serum levels of HGB， Alb， ALT， AST, TBIL， APTT， PT were measured， and complications were assessed. Results The physical condition of all donors were good before operations and were all in grade Ⅰaccording to ASA. Under general anesthesia of intravenous and inhalation, electrocardiogram, O2 saturation, blood pressure and body temperature were continuously monitored. A radial arterial catheter and a central venous catheter were placed. Blood lavement was utilized intraoperatively in all patients. All donors maintained stable life signs intraoperatively. The average intraoperative blood losses was （603.13±317.00） ml, and donors were transfused with autologous blood 〔(381.25±171.15) ml〕, with only 4 donors required homologous blood transfusion. HR and mean arterial blood pressure (MAP) showed no significantly variations intraoperatively (Pgt;0.05). Compared with controlled central venous pressure (CVP) before and right after hepatectomy, CVP increased significantly (P＜0.05) when intubation and abdomen-closing were carried. After hepatectomy and on the first day after operation, HGB and Alb decreased significantly (P＜0.05); ALT, AST and TBIL increased significantly (P＜0.05). Right after hepatectomy, PT increased instantly and significantly (P＜0.05); On the first day after operation, APTT began to increase significantly (P＜0.05). All donors came around completely and were extubated in the liver transplantation intensive care unit on the first day after operation. There were 3 cases (6.38%) of postoperative complication, which were biliary leakage, portal vein thrombosis and serious pleural effusion. Those 3 donors were cured after treatment. Conclusion Inhalation and intravenous general anesthesia of propofol, remifen-tanil and isoflurane can maintain stable life signs and reduce liver injury. Steady anesthesia, sufficient oxygenation and effective blood protection measures, for example, by decreasing CVP to prevent bleeding and by reclaiming autologous blood to avoid transfusing homologous blood, are keys for the safety of the donor and the prevention of complications.
Objective To investigate the effect of perioperative body temperature on the survival of skin flap grafting. Methods From July 2005 to November 2006, 50 cases of Ⅰ-Ⅱ grade patients undergoing elective skin flap grafting were randomly divided 2 groups. Pharyngeal temperature (PT) and skin temperature(ST) were monitored and recorded every 15 minutes. Operativetime, anesthetic time, time from the end of operation to extubation, the volume of blood transfusion, the volume of fluid transfusion and the flap survival 7 days after operation were recorded. In the experimental group, the body temperature was maintained in normal range with water market and forced air heater. In the control group， the body temperature was only monitored without any treatment. Results There were no significant differences in operating room temperature, operative time, anesthetic time, the volume of blood transfusion and fluid transfusion between 2 groups(Pgt;0.05). After induction, PT decreased gradually inboth groups during the first 45 minutes, compared with the time point of intubation(Plt;0.05),but there were no significant differences between the 2 groups(Pgt;0.05); and ST rose in both groups during the first45 minutes, compared with the time point of intubation (Plt;0.05). After 45 minutes of induction, in the experimental group, PT was in the normal range(36℃), and ST didn’t change compared with that of the timepoint of induction(Pgt;0.05). In the control group, both PT and ST decreasedgradually and timedependently compared with the time point of intubation (Plt;0.05). In the experimental group, PT and ST at each time point were higher than those in the control group (Plt;0.05). All the skin flap grafts survived in the experimental group, and skin flap grafts necrosed in 2 cases in the control group.Conclusion Keeping normal body temperature can improve the survival ofskin flap grafting. Therefore, the body temperature should be monitored and maintained in a normal range.
ObjectiveTo evaluate the difference between the tracheal intubation connected to conventional ventilation (TI-CV) and rigid bronchoscopy connected to high frequency ventilation (RB-HFV) under general anesthesia on patients with transbronchial cryobiopsy (TBCB).MethodA prospective, randomized, controlled trial was conducted in interstitial lung disease patients with TBCB from August 2018 to February 2019 in the First Affiliated Hospital of Guangzhou Medical University. According to the different methods of intubation, the patients were divided to a TI-CV group and a RB-HFV group randomly. The operating duration, extubation duration, total anesthesia time, heart rate, blood pressure and arterial blood gas analysis were collected and analyzed.ResultsSixty-five patients were enrolled. There were 33 patients with an average age of (48.0±15.0) years in TI-CV group and 32 patients with an average age of (48.8±10.8) years in RB-HFV group. The basic line of body mass index, pulmonary function (FEV1, FVC and DLCO), arterial blood gas (pH, PaO2 and PaCO2) and heart rate (HR), mean arterial pressure (MAP) had no significant differences between two groups. At the first 5 minutes of operation, the pH was (7.34±0.06) and (7.26±0.06), and the PaCO2 was (48.82±9.53) and (62.76±9.80) mm Hg in TI-CV group and RB-HFV group respectively, with significant differences (P=0.000). At the end of operation, the pH was (7.33±0.06) and (7.21±0.08), the PaCO2 was (48.91±10.49) and (70.93±14.83) mm Hg, the HR were (79.6±21.1) and (93.8±18.7) bpm, the MAP were (72.15±13.03) and (82.63±15.65) mm Hg in TI-CV group and RB-HFV group respectively, with significant differences (P<0.05). There were no differences in the operating duration and extubation duration between two groups. The total anesthesia time was (47.4±8.8) and (53.3±11.6) min with significant difference (P=0.017). Five minutes after the extubation, there were no significant difference in the pH, PaO2, PaCO2, HR and MAP between two groups. No serious complications occurred in either group.ConclusionsCompared with rigid bronchoscopy, TI-CV under general anesthesia is more conducive to maintain effective ventilation, and maintain the HR and MAP stable during the TBCB procedure. TBCB procedure should be performed by TI-CV under general anesthesia in patients with poor cardiopulmonary function.
Objective To explore the effect of pain management by anesthesia nurses on labor analgesia. Methods A total of 100 parturient women in the Affiliated Hospital of North China University of Science and Technology between July and August 2015 were randomly divided into two groups: analgesia group and control group with 50 in each. Both two groups accepted labor analgesia routine maternity nursing. Analgesia group accepted maternal perinatal term pain management in addition to the routine nursing. Then we compared degree of pain during the production process, labor time and perineal injury between the two groups of women. Results The number of women with a labor pain degree of 0-Ⅲ in the analgesia group was respectively 36 (72%), 12 (24%), 2 (4%) and 0 (0%), and the number in the control group was respectively 23 (46%), 17 (34%), 8 (16%), and 2 (4%). The above difference between the two groups was statistically significant (Z=–2.908, P =0.004). The number of women with intact perineum, perineal injury of lateral and median cut, and Ⅰ-Ⅲ degree laceration in the analgesia group was respectively 31 (62%), 7 (14%), 8 (16%), 4 (8%) and 0 (0%); and the number in the control group was respectively 21 (42%), 12 (24%), 10 (20%), 7 (14%) and 0 (0%), also with significant difference between the two groups (Z =–2.028, P =0.043). The first and second labor stage of the analgesia group was (462.32±101.27) and (63.58±10.38) minutes, and was (568.27±113.28) and (76.92±11.24) minutes in the control group, with significant differences between the two groups (P<0.001). There was no statistically significant difference between the two groups in the third labor stage (5.78±3.02) and (5.97±2.96) minutes, (P=0.654). Conclusions The implementation of pain management by anesthesia nurses on labor analgesia can significantly reduce maternal labor pain, shorten the time of labor, and the condition of the perineal injury is mild and easily acceptable. It is worthy of clinical promotion.
The anesthetic work of day surgery should be guided by the standardized perioperative evaluation system. The evaluation methods and standards with strong operability and repeatability are the prerequisites to ensure the safety and efficiency of day surgery. For the assessment of patients’ preoperative physiological status, preoperative preparation and postoperative rehabilitation, standardized work procedures should be established to ensure patients’ medical safety to the greatest extent. Through summarizing the advanced management experience of day surgery anesthesia at home and abroad, and combining with the principled suggestions in The Consensus of Chinese Experts on Anaesthesia for Day Surgery, the First Affiliated Hospital of Dalian Medical University has repeatedly revised the perioperative anesthesia evaluation methods in practice, and gradually explored a comprehensive, rigorous and standardized perioperative anesthesia evaluation system. This paper will focus on the evaluation of perioperative anesthesia and postoperative follow-up procedures in day surgery.
Since the proposal of enhanced recovery after surgery (ERAS), significant progress has been made in different surgical fields, but ERAS in thoracic surgery is still in its infancy. This article summarizes the research results of scholars at home and abroad, and provides a comprehensive overview of the ERAS anesthesia management pathway during the perioperative period of thoracic surgery from the aspects of preoperative evaluation, anesthesia scheme selection, ventilation strategy, fluid management, temperature protection, pain management, postoperative nausea and vomiting, and early mobilization. The aim is to provide a reference for ERAS management in thoracoscopic lung cancer surgery.
Objective To investigate the preventive effect of rapid preoxygenation technique on hypoxia caused by respiratory depression during outpatient obstetrics-gynecology operations. Methods According to a computer-generated random sequence, a total of 120 ASA I-II patients undergoing outpatient obstetrics-gynecology operations were randomly allocated into the trial group or the control group, 60 in each group. Patients in the control group received preoxygenation with tidal volume breathing. Patients in the trial group received preoxygenation with eight deep breaths (DB) in 1 min before anesthesia. All patients were induced with midazolam 1 mg, fentanyl 1μg /kg and propofol 2 mg/kg, and were maintained with propofol when needed. The following parameters were observed, including the incidences of respiratory depression and apnea, the onset time of anesthesia, the total doses of propofol as well as the changes in PetCO2 and SpO2. Results No significant differences were observed in demographic characteristics, the onset time of anesthesia, the total doses of propofol, and the incidences of respiratory depression and apnea between the two groups (P gt;0.05). However, the SpO2 in the control group was decreased significantly with a higher incidence of hypoxia (Plt;0.05). Conclusions Rapid preoxygenation technique may increase the oxygen reserves and improve the tolerance to hypoxia. It is effective in avoiding hypoxia caused by respiratory depression and apnea during outpatient obstetrics-gynecology operations.
Objective To explore the clinical application of the postanesthetic autologus donation and the post-operative transfusion during the knee and hipreplacement surgeries. Methods Thirty-three patients (17 males,16 females) admitted for the elective joint replacement surgeries from September 2004 to January 2005 were included in this study. Of the 33 patients, 5 were diagnosed with rheumatoid arthritis, 23 with femoral head necrosis, and 5 with knee osteoarthritis. Immediately after anesthesia, 400 ml of the blood was drawn and transfused after the surgery. The blood pressure was monitored during the blood drawing, postoperative blood parameters were recorded, surgical site drainage and signs of infections were observed, and the other clinical data were collected.Results Of the 33 patients, 27 only received autologoustransfusion, including 21 patients who underwent the unilateral hip replacement and 6 patients who underwent the unilateral knee replacement. All these 6 patients with the unilateral knee replacement received the blood drained from the surgical sites in addition to the blood obtained from the postanesthetic autologous donation. Another 6 cases with the bilateral hip and knee replacement received the blood drained from the surgical sites, the blood obtained from the post-anesthetic autologous donation and 400 ml of the allogeneic blood transfusion. The blood received postoperatively averaged 650 ml (range, 200-1 150 ml), haemoglobin(Hb) was averaged 88 g/L (68-102 g/L), and Hct was averaged 24.6% (20.5% 31.5%). Hb and Hct were lower after operation than before operation(Plt;0.01). Conclusion Postoperative blood transfusion following the postanesthetic and preoperative autologous donation can be successfully applied to most of the patients undergoing theknee or hip replacement so as to reduce complications of the allogeneic blood transfusion.
Objective To assess the efficacy and safety of sevoflurane versus ketamine in the anesthesia of child short period surgery. Methods Such databases as EMbase, PubMed, The Cochrane Library, CNKI, VIP, CBMdisc, Ongoing Controlled Trial and Conference Articles were searched from their establishment to April 2011 to collect randomized controlled trials (RCTs) and the quasi-RCTs. The quality of those studies meeting the inclusive criteria was assessed, the data were extracted and the meta-analysis was conducted by using RevMan 5.1.1 software. Results Ten studies involving 600 participants were included. Seven studies showed that the intraoperative heart rate of the sevoflurane group was lower than that of the ketamine group (MD= –11.85, 95%CI –16.47 to –7.23, Plt;0.000 01). Nine studies showed that the revival time of the sevoflurane group was shorter than that of the ketamine group (MD= –29.05, 95%CI –37.98 to –20.12, Plt;0.000 01). Three studies showed that the anesthesia induction time of the sevoflurane group was shorter than that of the ketamine group (MD= –208.45, 95%CI –359.22 to –57.68, P=0.007). Six studies showed that the influence on mean arterial pressure (MAP) had no significante difference (MD= –4.86, 95%CI –10.02 to 0.29, P=0.06). Meanwhile, seven studies showed that the adverse events of the sevoflurane group were fewer than those of the ketamine group (Peto OR=0.29, 95%CI 0.20 to 0.40, Plt;0.000 01). Conclusion The results of this system review show that sevoflurane is more effective than ketamine with fewer adverse reactions, and it provides a new choice for clinical anesthesia for child short period surgery. However, ketamine is still the main drug in clinical anesthesia for the child short period surgery at present, so high quality studies are needed for further clinical researches.
