硬膜外自控镇痛在老年下肢手术患者中的应用价值研究

The study of application of patient-controlled epidural analgesia(PCEA) on elderly patients with lower extremity surgery

目的：探讨硬膜外自控镇痛在老年下肢手术患者中的应用价值。方法：选取2011年10月～2013年10月于本院进行治疗的78例老年下肢手术患者为研究对象，将78例老年患者遵循随机分配的方式分为对照组（哌替啶肌内注射组）39例和观察组（硬膜外自控镇痛组）39例，然后将两组患者术后12h及24h的疼痛程度及血清应激指标进行比较。结果：观察组术后12h及24h 的轻度疼痛率均高于对照组，血清皮质醇及肾上腺素则均低于对照组，P均＜0.05，均有显著性差异。结论：硬膜外自控镇痛在老年下肢手术患者中的应用价值较高，可有效缓解患者的疼痛及改善其应激状态。

Objective：To discuss the application of patient-controlled epidural analgesia （PCEA） on elderly patients with lower extremity surgery.Method：78 elderly patients with lower extremity surgery admitted in our hospital from October 2011 to October 2013 were randomized into the control group and the observation group. Each group had 39patients. Patients in the control group was given pethidine intramuscular injection and that in the observation was given patient-controlled epidural analgesia（PCEA）.Compare the pain degree and serum stress index of the two groups respectively 12 and 24 hours after the surgery. Result：the 12h and 24h slight pain degree of the observation group were all higher than that of the control group（P〈0.05）. The serum cortisol and the epinephrine of the observation group were lower than that of the control group（P〈0.05）.Conclusion：PCEA has a good prospect of application on treating elderly patients with lower extremity surgery. It can relieve the pain of the patients and improve their stress state.
