不同氧疗法对腹部手术后患者低氧血症的影响

目的 :探讨腹部手术后低氧血症的最佳氧疗法。方法 :随机将上中腹部术后 10 0例分为观察组和对照组 ,每组 5 0例 ,观察组吸氧加止痛剂 ,对照组单用氧。比较两组术后低氧血症患者吸氧后 ,SPO2 变化及术后下床活动康复程度。结果 :术后 8h观察组 4 7例SPO2 达 98% ,有效率占 94 %。与对照组差异有高度显著性 (P <0 0 1)。观察组吸氧加止痛剂 ,80 %的患者术后第 6天能下床活动 ,与对照组差异有高度显著性 (P <0 0 1)。结论 :吸氧加止痛剂可使患者早期下床活动 ,有利于术后增加氧合 ,减少耗氧量 ,是改善术后低氧血症的有效措施。

The effect of different oxygen inhalational therapy on patients with hypoxemia after abdomen surgery

Objective:To explore the optiml oxygen inhalational therapy on patients with hypoxemia after abdomen surgery.Method:100 patients who accepted upper or mid abdomen surgery were divided into observation group and control group randomly.There were both 50 cases in each group.The cases in observation group were treated with oxygen inhalation and analgesic,and those in control group were treated only by oxygen inhalation.The change of SPO 2 and the rehabilitation of out-of-bed activities were compared between these two groups.Result:After 8 hours of oxygen inhalation,SPO 2of 47 cases in observed group were observed to reach 98% and the effectiveness rate was 94%.There was significant difference between the observed group and the control group(P<0.01).80% patients who were treated with oxygen inhalation and analgesic were able to doing out-of-bed activity with 6 days after operation.There was significant difference between the observed group and the control group(P<0.01).Conclusion:Oxygen inhalation and analgesic may be helpful for patients in early out-of-bed activity,increasing oxygenation after operation,decreasing oxygen consumption,and facilitating early rehabilitation discharge.It may be an effective measure for improving the hypoxemia after operation.
