应用PCEA与PCIA时夜间SPO_2变化的对比观察

Comparative Observation of SpO_2 in Night application between PCEA and PCIA

目的 观察硬膜外术后镇痛 (PCEA)与静脉术后镇痛 (PCIA)对病人夜间SPO2 的影响。方法 随机将 4 0例ASA -Ⅰ级的择期上腹部手术病人分 2组。Ⅰ组 2 0例 ,连续硬膜外麻醉术毕应用PCEA ;Ⅱ组 2 0例 ,全麻术毕应用PCIA。术后当日 7h记录病人SPO2 的变化 ,用SPSS软件包做统计学处理。结果 Ⅰ组和Ⅱ组记录的时间点SPO2 变化差异无显著差异 (P >0 0 5)。结论 我们得出术后病人应用PCEA和PCIA同样可使病人处于较长时间的轻度缺氧状态 ,老年患者及ASAⅡ级以上的病人术毕应用PCEA或PCIA应严密监测夜间血氧变化 ,必要时适量吸氧。

Objective To observe the affections of PCEA and PCIA on the patients in night.Methods The 40 cases of epigastric operation patients with ASA-Ⅰ were divided into two groups randomly.The patients in group Ⅰ were underwent with PCEA and patients in group Ⅱ were underwent with PCIA after general anesthesia.The SpO 2 of patients were recorded 7h after operation and analyzed with SPSS.Results There was no significant difference between two groups SpO 2 in the time recorded(P>0 05).Conclusion The application of PCEA and PCIA might make patient in slightly anoxic state for a long time.The SpO 2 should be monitored strictly after operation for senile and patient above ASA-Ⅱ and O 2 should inhale if necessary.
