摘要
目的观察不同浓度罗哌卡因混合芬太尼病人自控硬膜外镇痛(PCEA)用于经耻骨上前列腺切除术(SPP)后的效果。方法SPP病人36例,ASAⅡ或Ⅲ级,随机分为3组：0.12%罗哌卡因混合芬太尼PCEA组(RL组)、0.2%罗哌卡因混合芬太尼PCEA组(RH组)和吗啡病人自控静脉镇痛(PCIA)组(M组),每组12例。记录术后第6、24、48和72小时(T_6、T_(24)、T_(48)和T_(72))运动神经阻滞程度评分(Bromage评分)；记录术后即刻～＜6h、术后6～＜24h、术后24～＜48h和术后48～72h时段膀胱痉挛次数；采用视觉模拟评分法(VAS)记录病人膀胱痉挛时和非痉挛时疼痛程度；记录有关的副作用及术后72h膀胱冲洗液内红细胞的总数。结果1.T_6时Bromage评分RL组和RH组高于M组(P＜0.05或0.01),T_(24～72)时RH组高于RL组和M组(P＜0.01),RL组与M组之间差异无统计学意义。2.膀胱痉挛次数在术后6h内三组差异无统计学意义,术后6～72h,RL组和RH组低于M组(P＜0.05),其中术后6～＜24 h RH组少于于RL组(P＜0.05),术后24～＜72h,RH组和RL组之间差异无统计学意义。3.在膀胱痉挛时,VAS评分RH组和RL组低于M组(P＜0.05),H组与RL组差异无统计学意义；在非膀胱痉挛时,三组之间差异无统计学意义。4.RL组和RH组术后72h膀胱冲洗液内红细胞总数低于M组(P＜0.01),RL组与RH组差异无统计学意义。结论与吗啡PCIA相比,SPP后使用0.12%或0.2%的罗哌卡因混合芬太尼进行PCEA,能更有效地减少膀胱痉挛,减少前列腺窝创面的出血量。SPP后不同时段采用不同浓度的罗哌卡因混合芬太尼进行PCEA,效果更好。
Objective To investigate the efficacy of patient-controlled epidural analgesia （PCEA） with ropivacaine plus fentanyl for postoperative analgesia after suprapubic prostatectomy （SPP） , Methods Thirty-six ASA Ⅱ or Ⅲ patients aged 62-78 yrs weighing 52-84 kg undergoing SPP were randomly divided into 3 groups with 12 patients in each group： group Ⅰ received PCEA with 0, 12% ropivacaine and fentanyl 1 μg·ml^-1 ; group Ⅱ received PCEA with 2% ropivacaine and fentanyl 1 μg·ml^-1 and group m received patient-controlled intravenous analgesia （PCIA） with morphine 0.2 mg·ml^-1, Postoperative pain was assessed using VAS （0 = no pain, 10 = worst pain）, The degree of motor blockade （modified Bromage scale） was evaluated at 6, 24, 48 and 72 h after operation （T1-4）, Bladder spasm episodes were recorded. Side effects including nausea, vomiting and pruritus and the total number of RBC in rinse solution were also recorded. Results （ 1 ） Bromage score （0 = no motor block, 3 = inability to flex ankle joint） was significantly higher in group Ⅰ and Ⅱ than in group Ⅲ at T1 （6 h after op. ） , but significantly lower in group Ⅰ and Ⅲ than in group Ⅱ at T2-4 （24-72 h after operation）. （2） VAS score （0 = no pain, 10 = worst pain） was not significantly different among the 3 groups without bladder spasm but significantly higher in group m than in other 2 groups during episodes of bladder spasm. （3） The number of bladder spasm episodes was not significantly different among the 3 groups within 6h after operation, but was significant larger in group m than in the other two groups during 6-72 h after operation. During 6-24 h after operation more bladder spasm attacks occurred in group Ⅰ than in group Ⅱ . （4） The incidence of side effects was significantly lower and the total number of RBC in rinse solution was significantly smaller in group Ⅰ and Ⅱ than in group Ⅲ Conclusion PCEA with 0.12% or 2% ropivacaine plus fentanyl can effectively reduce the number of bladder spasm attack and postoperative bladder bleeding. Different concentrations of repivacaine shotdd be used for PCEA during different postoperative periods.
