开胸术后硬膜外自控镇痛与肌肉注射镇痛的比较

Patient Self-controlled Epidural Analgesia for Post-thoracotomy

目的 探讨硬膜外自控镇痛 (PCEA)在开胸术后镇痛的临床效果。方法 选择 86例在全麻下开胸手术的ASAⅠ～Ⅱ级病人 ,随机分成PCEA组 ,4 5例 ;和肌肉注射镇痛组 (MI组 ,4 1例 )。比较其两组病人的镇痛效果 ,监测术前、术后病人的呼吸频率 (RR)、分钟通气量 (MV)和脉搏血氧饱和度 (SpO2 )的变化。结果 PCEA组镇痛效果明显优于MI组 ,两组有显著性差异 (P <0 0 0 5 ) ,前者各种并发症显著下降。结论 PCEA是开胸术后理想的镇痛方法 ,它可以改善肺功能和提高术后康复质量。

Objective To study the analgesic clinical effect of patient self-controlled epidural analgesia(PCEA) in post-thoracotomy pain.Methods Eighty-six patients(ASA statge I or II)underwent thoracotomy with general anesthesia were randomly assigned to two groups after operation,PCEA group:45 cases,muscular injection(MI) group:41 cases.Comparing the effect and the side effect of analgesia between them.Respiratory rate(RR),volume of ventilation(MV) minute and SpO 2 were recorded before and after operation.Results In PCEA group, the scores of analgesic scale was significantly superior than that in MI group(P<0 005).The incidence of complication was much lower than that in MI group.Conclusions PCEA is a good method of easing pain after thoracic surgery.It can improve respiratory function and life quality,for postoperative patients.
