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.
Objective To evaluate the effectiveness of intravenous patient-controlled analgesia versus epidural patient-controlled analgesia for postoperative analgesia, sedation, and the incidence of side effects. Methods We searched the specialized trials registered in the Cochrane anesthesia group, The Cochrane Library (CCTR), MEDLINE (1966 to Sept. 2008), EMbase (1966 to Sept. 2008), PubMed (1966 to Sept. 2008), and handsearched some Chinese anesthesia Journals and Clinical anesthesia journals. Randomized controlled trials (RCTs) and quasi-RCTs of intravenous versus epidural analgesia for post-operation were included. The quality of the trials was critically assessed. RevMan 4.2.8 software was used for meta-analyses. Results Thirteen RCTs involving 580 patients of intravenous versus epidural analgesia for post-operation were included. The results of meta-analyses showed that there were no significant differences in postoperative analgesia and sedation at the hour-points of 2nd, 4th, 8th, 12th, and 24th hours after operation. There were no significant differences in plasma fentanyl concentration in the two groups on the same analgesia effects. There were also no significant differences in side effects. Conclusion Both intravenous patient-controlled analgesia and epidural patient-controlled analgesia have the same clinical effects. Compared with epidural patient-controlled analgesia, intravenous patient-controlled analgesia has fewer side effects and is more convenient. At the same time, it can reduce more costs of hospitalization. But because of the low quality and small sample size of the included studies, more well-designed, large scale, randomized controlled trials are needed.
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 observe the effects of epidural anaesthesia (EA) and general anaesthesia (GA) on the changes of plasma epinephrine (E) and norepinephrine (NE) during laparoscopic cholecystectomy (LC). Methods Thirty patients undergoing elective LC were randomly divided into GA group (n＝15) and EA group (n＝15). The concentrations of plasma NE and E were measured at the following phases: before anaesthesia, before introducing pneumoperitoneum, during pneumoperitoneum, and at the end of operation. Results In EA group, the concentrations of NE weren′t significantly different at each phase, the concentrations of E significantly increased before and during pneumoperitoneum (Ｐ＜0.05) and returned to the baseline at the end of operation (Ｐ＞0.05). In GA group, the concentrations of NE and E didn′t change significantly before pneumoperitoneum, but increased during pneumoperitoneum (Ｐ＜0.05) and E didn′t return to the baseline at the end of operation (Ｐ＜0.05). The E concentrations of EA group was higher than that of GA group before pneumoperitoneum, but the NE concentration of EA group was lower than that of GA group during pneumoperitoneum (Ｐ＜0.05). Conclusion Both groups has significant stress reaction, but the stress reaction of EA group is weaker than that of GA group during LC.

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.

Methods Data was collected from April 2009 to November 2009. Sixty patients after cesarean section under continuous epidural anesthesia were randomly divided into three different groups.Group A was given sufentanil 0.3 μg/mL and 0.125% ropivacaine for PCEA, group B was given sufentanil 0.4 μg/mL and 0.125% ropivacaine, group C was given sufentanil 0.5 μg/mL and 0.125% ropivacaine. The analgesia effects were evaluated by the visual analogue scales (VAS). Side effects were also recorded. Results The VAS scores were significantly the highest in group A than that in group B and group C, the VAS scores in group B were higher than that in group C (Plt;0.05). The incidence of side effects, such as postoperative nausea and vomiting, lethargy, and pruritus, was not significant among the three groups (Pgt;0.05). Conclusion 0.5 μg/ mL sufentanil and 0.125% ropivacaine recommended for PCEA with background 4 mL/h is safe and effective for patients after cesarean section.
Objective To explore effective substances and methods for prevention of peridural adhesion. Methods Laminectomy was performed on the 5th lumbar segment in 64 rabbits, which were equally divided into 4 groups. The duramater (12 mm×6 mm) was exposed. The exposed duramater was left uncovered in Group A; the exposed dura mater was covered with sodium hyaluronate jel (high molecular weight, 1 ml) in Group B; the lamina repair was performed with the autologous spinous process in Group C; the lamina repair was performed with the sodium hyaluronate jel filling and the autologous spinousprocess in Group D. The specimens were observed grossly and histologically at 2, 4, 6 and 8 weeks postoperatively. The computed imaging analysis on the epidural adhesion was also performed at 6 weeks postoperatively. Results ①The gross anatomical evaluation: Severe peridural adhesion was formed in Group A, less adhesion formed in Groups B and C, but no obvious adhesion formed in Group D. ②The area percentage of the epidural scar: The area percentage ofthe epidural scar was 15.89%±1.88% and 13.94%±1.89% in Groups C and D respectively, which were significantly lower than those in Groups A and B (22.66%±2.89% and 20.70%±2.82%,Plt;0.05). ③The density of epidural scar: Thedensity of the epidural scars were 42.03%±7.36% and 36.50%±9.08% in Groups B and D, which were significantly lower than those in Groups A and C (63.73%±6.06% and 52.11%±4.10%，Plt;0.05). Conclusion The high molecular weight sodium hyaluronate jel filling combined with the lamina repair using the autologous spinous process has the best preventive effect on the peridural adhesion after laminectomy.
