This study was carried out to evaluate whether preoperative administration of intramuscular dezocine can provide postoperative analgesia and reduce postoperative opioid consumption in patients undergoing laparoscopic cholecystectomy. Patients （ASA Ⅰ or Ⅱ ） scheduled for laparoscopic cholecystectomy were randomly assigned into intramuscular dezocine group （group 1） or intramuscular normal saline group （group 2）. Dezocine and equal volume normal saline were administered intramuscularly 10 rain before the induction of anesthesia. After operation, the severity of postoperative pain, postoperative fentanyl requirement, incidence and severity of side-effects were assessed. Postoperative pain and postoperative patient-controlled fentanyl consumption were reduced significantly in group l compared with group 2. The incidence and severity of side effects were similar between the two groups. Preoperative single-dose administration of intramuscular dezocine 0.1 mg/kg was effective in reducing postoperative pain and postoperative patient-controlled fentanyl requirement in patients undergoing laparoscopic cholecystectomy.展开更多

文摘目的通过观察不同麻醉维持方式下妇科腹腔镜手术患者术后疼痛的情况,比较七氟醚或丙泊酚维持麻醉对患者术后疼痛的影响。方法选择择期行妇科腹腔镜手术女性患者60例,年龄18~65岁,BMI 18~30 kg/m^2,ASAⅠ或Ⅱ级。采用随机数字表法随机分为七氟醚组(S组)和丙泊酚组(P组),每组30例。两组以相同方案麻醉诱导后,S组吸入1.5%~4%七氟醚维持麻醉,P组靶控输注丙泊酚,血浆靶浓度3~6μg/ml。术中维持BIS 40~60。记录术后30 min、1、3、6、24和48 h时患者活动时VAS评分;记录术前1 d、术后3、24和48 h机械性痛阈值;记录术后24 h PCIA按压次数、芬太尼消耗量;记录追加哌替啶的例数和恶心呕吐、寒颤、瘙痒、躁动等不良反应发生情况。结果与术后30 min比较,术后3、6 h两组活动时VAS评分明显升高(P<0.05),术后48 h明显降低(P<0.05)。术后30 min、1和3 h P组活动时VAS评分明显低于S组(P<0.05)。与术前1 d比较,术后3、24和48 h S组机械性痛阈明显降低(P<0.05),术后3 h P组机械性痛阈明显降低(P<0.05)。术后3 h P组机械性痛阈值明显高于S组(P<0.05)。两组PCIA按压次数、芬太尼消耗量、追加哌替啶情况和不良反应发生情况等差异无统计学意义。结论与七氟醚吸入维持麻醉比较,妇科腹腔镜手术中使用丙泊酚静脉维持麻醉可以提高患者术后的机械性痛阈,减轻患者在术后3 h内的疼痛。
