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.
Objective To investigate the clinical effect of polylactic acid membrane in prevention of epidural scar and adhesion. Methods From July 1998 to April 2000, 62 patients with lumbar disc herniation were randomly assigned into two groups. All were treated surgically with discectomy by fenestration or laminectomy.One group were placed with a thin of polylactic acid membrane covering the interlaminar space(n=32). The thickness of the film was 0.1mm. The other group was blank control(n=30). After 2 weeks of operation, we observed the local and systemic reactions. After 6 months clinical symptoms were revaluated and the degrees of epidural scar and adhesion were determined by CT scans. Results After 2 weeks, we found no adverse systemic reactions in all patients. Wound healing was excellent. No abnormalities of hepatic and renal functions as well as blood for routine were found. Temperature after operation was normal. After 6 months, the curative effects were as follows in experimental group and in control group: excellent in 27 patients and in 24 patients, good in 4 patients and in 4 patients, fair in 1 patient and in 1 patient, and poor in 0 patient and in 1 patient, respectively. There are no significant difference between two groups. The CT scans showed no adhesion between the epidural scar and the dural sac in all patients of experimental group. There existed various extents of adhesion in control group. Conclusion The results demonstrate that the polylactic acidmembrane can effectively prevent the epidural scar adhesion with a good biocompatibility and no toxity. Its clinical application was promising.
Objective?To systematically evaluate the effects of thoracic epidural anesthesia on outcome after coronary artery bypass surgery. Methods?We searched PubMed, EBSCO, Springer, Ovid, and CNKI databases from 1990 through Oct. 2009 to identify randomized controlled trials (RCTs) about thoracic epidural anesthesia combined with general anesthesia versus general anesthesia alone on outcome after coronary artery bypass surgery. The methodological quality of the included RCTs was assessed and the data was extracted according to the Cochrane Reviewer’s Handbook. The homogeneous RCTs were pooled using RavMan 4.2.10 software. Results?Sixteen RCTs involving 1 316 patients met the inclusion criteria. The results of meta-analyses showed that thoracic epidural anesthesia significantly reduced time to tracheal extubation (MD= –332.43, 95%CI –640.19 to –24.68, P=0.03), visual analog scale (VAS) scores at rest on postoperation day 1 (MD= –1.23, 95%CI –2.19 to –0.27, P=0.01), VAS scores with movement on postoperation day 1 (MD= –2.52, 95%CI –4.65 to –0.39, P=0.02) and day 2 (MD= –1.5, 95%CI –2.56 to –0.43, P=0.006), and incidences of myocardial ischemia (RR=0.53, 95%CI 0.29 to 0.97, P=0.04). There were no significant differences between the two groups in postoperative pulmonary function, incidences of myocardial infarction, atrial fibrillation, and mortality. Conclusions?Thoracic epidural anesthesia could reduce postoperative time to tracheal extubation, VAS score, and incidences of myocardial ischemia, but it does not affect postoperative pulmonary function, incidences of myocardial infarction, atrial fibrillation, and mortality. More high-quality RCTs are required.
Objective To compare the effect of intravenous and epidural analgesia on postoperative complications after abdominal and thoracic surgery. Methods A literature search was conducted by using computerized database on PubMed, EBSCO, Springer, Ovid, and CNKI from 1985 to Jan 2009. Further searches for articles were conducted by checking all references describing postoperative complications with intravenous and epidural anesthesia after abdominal and thoracic surgery. All included randomized controlled trials (RCTs) were assessed and data were extracted by the standard of Cochrane systematic review. The homogeneous studies were pooled using RevMan 4.2.10 software. Results Thirteen RCTs involving 3 055 patients met the inclusion criteria. The results of meta-analyses showed that, a) pulmonary complications and lung function: patient-controlled epidural analgesia can significantly decrease the incidence of pneumonia (RR=0.66, 95%CI 0.53 to 0.83) and improve the FEV1 (WMD=0.17, 95%CI 0.05 to 0.29) and FVC (WMD=0.21, 95%CI 0.1 to 0.32) of lung function after abdominal and thoracic surgery, but no differences in decreasing postoperative respiratory failure (RR=0.77, 95%CI 0.58 to 1.02) and prolonged ventilation (RR=0.75, 95%CI 0.51 to 1.13) compared with intravenous analgesia; b) cardiovascular event: epidural analgesia could significantly decrease the incidence of myocardial infarction (RR=0.58, 95%CI 0.35 to 0.95) and arrhythmia (RR=0.64, 95%CI 0.47 to 0.88) than the control group, but could not better reduce the risk of heart failure (RR=0.79, 95%CI 0.47 to 1.34) and hypotension (RR=1.21, 95%CI 0.63 to 2.29); and c) Other complications: epidural and intravenous analgesia had no difference in decreasing the risk of postoperative renal insufficient (RR=0.78, 95%CI 0.53 to 1.14), gastrointestinal hemorrhage (RR=0.78, 95%CI 0.49 to 1.23), infection (RR=0.89, 95%CI 0.70 to 1.12) and nausea (RR=1.03, 95%CI 0.38 to 2.81). Conclusions Epidural analgesia can obviously decrease the risk of pneumonia, myocardial infarction and severe arrhythmia, and can improve the lung function after abdominal or thoracic surgery.
【摘要】 目的 比較術后芬太尼皮下鎮痛（PCSA）與硬膜外鎮痛（PCEA）的臨床效果，以及對胃腸功能的影響。 方法 2009年1-6月間觀察擇期硬膜外麻醉下經腹子宮切除術患者120例，術后分別實施PCSA與PCEA，觀察術后第4、8、12、24、48 h的鎮痛、鎮靜情況，呼吸循環、惡心嘔吐及其他不良事件，記錄術后首次肛門排氣時間，測評術后鎮痛滿意度。 結果 術后兩組患者鎮痛優良率均在90%以上，各時點鎮痛評分、鎮靜評分、惡心嘔吐發生率、首次肛門排氣時間以及患者鎮痛優良率差異均無統計學意義（Pgt;0.05）。 結論 術后芬太尼PCSA與PCEA一樣，效果確切，對術后胃腸功能無明顯影響，患者滿意，是一種安全、有效的鎮痛方法。【Abstract】 Objective To compare clinical efficiency and gastrointestinal reaction of subcutaneous patient-controlled analgesia (PCSA) and epidural patient-controlled analgesia (PCEA) with fentanyl analgesic for patients after operation. Methods A total of 120 patients having undergone transabdominal hysterectomy under epidural anesthesia between January and June 2009 accepted PCSA or PCEA after operation. We evaluated the state of analgesia and sedation at the 4th, 8th, 12th, 24th and 48th hour after operation. We also looked into the respiration, blood circulation, nausea, vomiting and other abnormal events of the patients during the first 48 hours after operation. At the same time, we recorded the first time of anal exsufflation after operation and the degree of patients’ satisfaction. Results The analgesic effective rate was higher than 90% in both groups. There were no significant differences in analgesia and sedation scores at above-mentioned points after operation, incidence of nausea and vomiting, first time of anal exsufflation or analgesic effective rate between the two groups. Conclusion PCSA with fentanyl can be as effective in relieving postoperative pain as PCEA with fentanyl without obvious adverse effect in the gastrointestinal function. Therefore, PCSA is a safe and effective method to alleviate postoperative pain.
Objective To investigate the most suitable anaesthesia method for the tension-free herniorrhaphy.Methods A total of 422 unilateral inguinal hernia cases from 2002 to 2005 were collected and randomly divided into the local anaesthesia group and epidural anaesthesia group. Observation indices and some relative data, such as operative duration, date of ambulation, date of foodintake, length of hospital stay, operation-correlated complications, anaesthesia complications, usage rate of ancillary drug, satisfactory rate for anesthesia, cost of hospitalization, were included and recorded in the questionnaire, and all the patients who took the tension-free herniorrhaphy were asked to answer it as the follow-up research. Results It was found that the occurrence of postoperative anaesthetic complications, the cost of hospitalization, length of stay of local anaesthesia group were significantly less than those of epidural anaesthesia group, and the date of moving and the date of foodintake were also significantly earlier than those of the other group (P＜0.05). However, there was no significant difference of operative duration, postoperative recovery situation and the satisfactory rate between two groups (P＞0.05).Conclusion The local anaesthesia is suitable for most of the tension-free herniorrhaphy, and it may be used as the conventional anaesthetic method.
【摘要】 目的 評價撫觸對硬膜外麻醉穿刺疼痛的影響及效果。 方法 2009年1-12月，將485例行硬膜外麻醉穿刺患者隨機分為撫觸組（術中行撫觸干預）和對照組（常規護理），觀察兩組患者的穿刺程度、穿刺時間。 結果 撫觸組患者疼痛程度、穿刺時間較對照組有明顯改善，且差異有統計學意義（Plt;0.01）。 結論 撫觸可降低應激引起的硬膜外麻醉穿刺患者的疼痛程度，保持穿刺體位從而縮短穿刺時間，有利于麻醉操作順利進行。【Abstract】 Objective To evaluate the effect of touching on alleviating the pain in patients undergoing epidural anesthesia puncture. Methods A total of 485 patients who underwent epidural puncture from January to December 2009 were randomly divided into two groups: 259 in touching group and 226 in control group. In the touching group, the patients were touched and consoled while undergoing epidural puncture. The pain extent and time of puncture were observed and recorded. Results The level of pain and time of puncture were obviously alleviated and shortened in the touching group and the difference between the two groups was statistically significant. Conclusion Touching could reduce the stress and pain caused by epidural puncture, which may lead to maintain the puncture position and thereby shorten the puncture time. It helps to finish the narcotic operation favorably.
