【摘要】 目的 比较舒芬太尼与等效剂量芬太尼在髋关节置换术后患者硬膜外镇痛的临床效果。 方法 2006年11月-2008年9月收治的50例硬膜外麻醉下髋关节置换术患者，随机分为两组（n=25）。芬太尼组（A组）:芬太尼0.75 mg加0.894%甲磺酸哌卡因20 mL加生理盐水至100 mL；舒芬太尼组（B组），舒芬太尼75 μg加0.894%甲磺酸哌卡因20 mL加生理盐水至100 mL硬膜外镇痛。其中，A组患者于手术结束时，静脉滴注格拉司琼3 mg。持续剂量2 mL/h，单次给药量（PCA）0.5 mL/次，锁定时间15 min。观察两组的镇痛效果，恶心、呕吐次数，记录脉搏血氧饱和度、心率、呼吸的变化。 结果 镇痛泵开机后，B组各时段镇静评分，2分以上者明显多于A组，镇痛评分明显低于A组，有统计学意义（Plt;0.05），两组术后恶心、呕吐发生率都较低，组间差异无统计学意义（Pgt;0.05）。两组4、12、24 h的呼吸频率和脉搏血氧饱和度差异有统计学意义（Plt;0.05），但48 h的呼吸频率和脉搏血氧饱和度无统计学意义（Pgt;0.05）。 结论 在等效剂量下，髋关节置换术后患者硬膜外镇痛，舒芬太尼明显优于芬太尼。【Abstract】 Objective To compare the clinical effect of epidural analgesia with sufentanil and fentanyl in an equivalent dose after hip replacement. Methods From December 2006 to September 2008, fifty cases of epidural anesthesia after hip replacement were randomly divided into two groups, each group had 25 cases. Group A (fentanyl group): fentanyl mesylate 0.75 mg+0.894% ropivacaine 20 mL+0.9% sodium chloride solution to 100 mL; group B (sufentanil group): sufentanil 75 μg+0.894% ropivacaine mesylate 20 mL+0.9% sodium chloride solution to 100 mL epidural analgesia. Patients in group A received intravenous infusion of granisetron 3 mg at the end of surgery. Continuous dose was 2 mL/h, with the volume of single dose (PCA) 0.5 mL per time and lockout time of 15 minutes. The analgesic effect, nausea, and vomiting frequency were observed, and the pulse oxygen saturation, heart rate, and breathing changes were recorded. Results After boot analgesia, S sedation scores for each phase and pain score in group B were significantly different compared with those in group A (Plt;0.05). Both groups had low incidence of nausea and vomiting, and the difference was not statistically significant (Pgt;0.05). The difference of respiratory rate and pulse oxygen saturation at 4 h, 12 h, 24 h was statistically significant between two groups (Plt;0.05), but at 48 h the difference was not significant (Pgt;0.05). Conclusion In the equivalent dose, epidural analgesia with sufentanil in the patients with hip replacement is superior to fentanyl.
ObjectiveTo investigate the effect of the interval between neoadjuvant chemoradiotherapy (nCRT) and surgery on the clinical outcome of esophageal cancer.MethodsPubMed and EMbase databases from inception to March 2018 were retrieved by computer. A random-effect model was used for all meta-analyses irrespective of heterogeneity. The meta-analysis was performed by RevMan5.3 software. The primary outcomes were operative mortality, incidence of anastomotic leakage, and overall survival; secondary outcomes were pathologic complete remission rate, R0 resection rate, and positive resection margin rate.ResultsA total of 17 studies with 18 173 patients were included. Among them, 13 were original studies with 2 950 patients, and 4 were database-based studies with a total of 15 223 patients. The results showed a significant positive correlation between the interval and operative mortality (Spearman coefficient=0.360, P=0.027). Dose-response meta-analysis revealed that there was a relatively better time window for surgery after nCRT. Further analysis for primary outcomes at different time cut-offs found the following results: (1) when the time cut-off point within 30-70 days, the shorter interval was associated with a reduced operative mortality (7-8 weeks: RR=0.67, 95% CI 0.55-0.81, P<0.05; 30-46 days: RR=0.63, 95%CI 0.47-0.85, P<0.05; 60-70 days: RR=0.64, 95%CI 0.48-0.85, P<0.05); (2) when the time cut-off point within 30-46 days, the shorter interval correlated with a reduced incidence of anastomotic leakage (RR=0.39, 95%CI 0.21-0.72, P<0.05); when the time cut-off point within 7-8 weeks, the shorter interval could achieve a critical-level effect of reducing the incidence of anastomotic leakage (RR=0.73, 95%CI 0.52-1.03, P>0.05); (3) when the time cut-off point within 7-8 weeks, increased interval significantly was associated with the poor overall survival (HR=1.17, 95% CI 1.00-1.36, P<0.05). Secondary outcomes found that the shorter interval could significantly reduce the positive resection margin rate (RR=0.53, 95% CI 0.38-0.75, P<0.05) when time cut-off point within 56-60 days.ConclusionShortening the interval between nCRT and surgery can reduce the operative mortality, the incidence of anastomotic leakage, long-term mortality risk, and positive resection margin rate. It is recommended that surgery should be performed as soon as possible after the patient's physical recovery, preferably no more than 7-8 weeks, which supports the current study recommendation (within 3-8 weeks after nCRT).
