摘　　要：目的:研究病人自控硬膜外镇痛(PCEA)对上腹部手术后乳酸值及血气分析影响。方法:择期上腹部手术病人30例,随机分两组,各15例。A组,术后肌注杜冷丁止痛,B组,术后行PCEA。术前及术后8h、24h、48h抽动脉血查乳酸值及血气分析。结果:所有病人术后乳酸值均升高,但B组较A组变化小(P<0.05);术后24hA组pH值和PaO2均较术前显著降低(P<0.05),而B组无显著性差异。结论:PCEA能有效的改善上腹部手术后病人的组织氧供,有利于术后康复。Objective To evaluate the effects of patient - controlled epidural analgesia(PCEA.) on lactic acid and blood gas levels after upper abdomen surgery. Methods Thirty patients undergoing upper abdomen surgery were randomly aivided into two groups,i. e. group A(n= 15)undergoing analgesia by pethidine(i. m. ) and group B(n= 15) undergoing FCEA. Lactic acid and blood gas were determined before the operation and 8,24 and 48 hours after the opertion. Results The lactic acid increased in both the groups after the operation and this change was siglificantly weaker in group B than that in group A ( P < 0.05 ). The pH and PaQ decreased significantly 24 hours after the operation compared with that before the operation in group A, but in group B they had no significant difference between before and after the operation. Conclusion PCEA is an effective method for improving oxygen supply in the patients undergoing upper abdomen surgery.
