ObjectiveTo analyze the occurrence of arrhythmia in patients during the recovery period of anesthesia, in order to take appropriate measures in nursing care to ensure the safety of patients. Method We carried out a retrospective analysis of 18 931 general anesthesia post-operative patients (aged 16-84 years old) transferred to anesthesia recovery from September 2012 to July 2013, and we observed the incidence rate of arrhythmia, and documented the clinical manifestations of the patients. ResultsDuring the anesthesia recovery, out of 18 931 general anesthesia postoperative patients, 269 cases of arrhythmia occurred, and the incidence rate was 1.42%. Twenty minutes after nursing intervention and use of medication, the difference of systolic blood pressure, bradycardic heart rate, and tachycardic heart rate of the patients were statistically better than those beofre the treatment (P＜ 0.05) . ConclusionEarly discovery and analysis of arrhythmia in patients during anesthesia recovery, along with timely provision of analgesic and antiarrhythmic treatment can effectively improve the circulation status of the patients, thus ensure the safety of the patients during anesthesia recovery.
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 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.
ObjectiveTo discuss the method and effectiveness of Wide-awake technique in flexor tendon tenolysis.MethodsThe clinical data of 16 patients (22 fingers) with flexor tendon adhesion treated by Wide-awake technique for flexor tendon tenolysis between May 2019 and December 2019 were retrospectively analyzed. The patients were all male, aged from 18 to 55 years old, with an average of 35 years old. Among them, 4 cases (7 fingers) after replantation of severed fingers, 4 cases (7 fingers) after flexor tendon rupture repair, and 8 cases (8 fingers) after open reduction and internal fixation of proximal fractures. The time from the original operation to this operation was 6-18 months, with an average of 8 months. The visual analogue scale (VAS) score was used to evaluate the patient’s pain during local anesthesia (when the first needle penetrated the skin), intraoperative, and 24 hours postoperatively; and the recovery of finger movement was evaluated by total finger joint active range of motion (TAM) evaluation system and Strickland (1980) standard after operation.ResultsIntraoperative hemostasis and anesthesia were satisfactory, and the patient could fully cooperate with the surgeon in active finger movements. There were different degrees of pain during local anesthesia (VAS score was 2-4), no pain during operation (VAS score was 0), and different degrees of pain after operation (VAS score was 1-8, 9 patients needed analgesics). All incisions healed by first intention after operation. All 16 cases were followed up 9-15 months with an average of 12 months. Finger function was significantly improved, no tendon rupture occurred. At last follow-up, the patients after proximal fracture open reduction and internal fixation were rated as excellent in 4 fingers and good in 4 fingers according to the TAM standard, and both were excellent according to the Strickland (1980) standard; and the patients after replantation of severed fingers and flexor tendon rupture repair were rated as excellent in 4 fingers and good in 10 fingers according to TAM standard, and as excellent in 6 fingers and good in 8 fingers according to Strickland (1980) standard.ConclusionWide-awake technique applied in flexor tendon tenolysis can accurately judge the tendon adhesion and release degree through the patient’s active activity, achieve the purpose of complete release, and the effectiveness is satisfactory; the effectiveness of tendon adhesion release surgery after fracture internal fixation is better than that of patients after tendon rupture suture and replantation.
ObjectiveTo assess impact of typical parameters recommended by enhanced recovery after surgery (ERAS) program in elective colorectal surgery, and provide some recommendations for surgeon and anesthesiologist. MethodThe published articles about ERAS program in elective colorectal surgery in recent years were searched in these databases(EMBASE, PubMed, Cochrane Library, Ovid), the impact of each parameter was evaluated basing on hospital stay and rate of postoperative complications. ResultsAfter analyzing the literatures, the parameters, which were applied in current rehabilitation programs and covered the pre-, intraand post-operative periods in colorectal surgery, were identified as potential impacting consequences of colorectal surgery. Strong agreements were obtained for the following recommendations:① Preoperative management:bowel preparation, fasting, preanesthetic medication, and nutritional care.② Intraoperative management:fluid management, preventing hypothermia, method of surgery and incision, drugs usages of antibiotics, glucocorticoid and prevention of postoperative nausea and vomiting.③ Postoperative management:managements of drainage tube, nasogastric intubation and urinary catheter, postoperative analgesia, prevention of thromboembolism, and measures of intestinal function recovery (including early mobilization, feeding and chew gum). ConclusionUse of a series of effective measures in ERAS has an effective result, could reduce surgical stress and complications, enhance recovery, shorten hospital stay.
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.
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.
Surgery is an important method for the treatment of malignant tumors. Sevoflurane is one of the most common general anesthetics, which can directly or indirectly affect the biological behavior of cells and the immune function of tumor patients, thereby affecting the recurrence and metastasis of tumor patients after surgery. From the aspects of microRNA, matrix metalloproteinase, phosphatidylinositol-3-kinase/Akt signaling pathway and hypoxia-inducible factor-1α, this article summarizes the molecular mechanisms of sevoflurane affecting the biological behavior of tumor cells, and clarifies the regulation mechanism of sevoflurane on the immune function of tumor patients. It is expected to provide a theoretical basis for precise anesthesia for tumor patients, and to provide medication basis for reducing postoperative recurrence and metastasis of tumor patients.
ObjectiveTo evaluate the clinical effects of nebulized lidocaine anesthesia and anesthesia with lidocaine and midazolam in patients with preoperative bronchoscopy. MethodsTotally, 136 inpatients between May 2002 and June 2013 with preoperative bronchoscopy were included in the study. The patients were randomly assigned to experimental group and control group with 68 patients in each. For patients in the experimental group, 8 mL of 2% lidocaine was administered through inhalation anesthesia, followed by 2-3 mg bolus of midazolam, and subsequently 0.5 mg of midazolam was administered every 2 minutes depending on patients' awareness. Patients in the control group accepted lidocaine alone for anesthesia. The clinical efficacy and adverse effects of both the two ways of anesthesia were observed. ResultsThe time of sustained and effective anesthesia was (24.5±2.8) minutes in the experimental group, as compared with (16.8±2.1) minutes in the control group (P<0.01). The average amount of consumption of lidocaine was (12.4±1.3) mL in the experimental group, as compared with (16.8±1.5) mL in the control group (P<0.01). The heart rate at 5 min after operation was (81.5±19.5) beats/min in the experimental group, as compared with (94.6±34.6) beats/min in the control group (P<0.01). The mean pulse oxygen saturation at 5 min after operation was (93.5±3.6)% in the experimental group, as compared with (88.2±13.3)% in the control group (P<0.01). ConclusionCombined application of lidocaine and midazolam before bronchoscopy is simple and feasible for anesthesia, which has higher success rate, lesser side effects and other reactions such as body movement and coughing.
