心肺复苏和创伤急救中氧利用率监测及预后

OXYGEN UTILIZATION COEFFICIENT AND PROGNOSIS OF CARDIOPULMONARY RESUSCITATION AND TRAUMATIC SHOCK

目的 :探讨氧利用率 (O2 UC)作为判断心肺复苏和创伤性休克病人预后的监测指标。方法 :对 2 6例病人 (其中急诊创伤 11例 ,心肺复苏 15例 )的O2 UC进行前瞻性监测。结果 :创伤休克 11例病人O2 UC为 0 3 7±0 0 7,全部救治成功 ;心肺复苏 15例病人O2 UC为 0 67± 0 2 7,14例死亡 ,1例救治成功 ,救治成功与死亡间有显著性差异 (P <0 0 0 1)。结论 :O2 UC持续在 0 67± 0 2 7时 ,病人预后严重。O2 UC >0 40是组织缺氧的危险限值 ,该指标可作为危重病人救治的监测指标。O2 UC监测简便、直观、灵敏。

Objective:To determine relation between prognosis of oxygen utilization coefficient(O 2UC)and cardiopulmonary resuscitation and traumatic shock.Method:The O 2UC of 26 patients (11 traumatic shock and 15 cardiopulmonary resuscitation) was monitored.Results:The value of O 2UC was 0.37±0 07 in 11 traumatic shock patients,who had been successfully treated.But of 15 patients undertaken cardiopulmonary resuscitation whose O 2UC was 0.67±0 27,14 died and only 1 was successfully treated.Success rate and mortality was significantly different (P<0 001).Conclusion:Patients with O 2UC 0.67±0.27 have a bad prognosis.O 2UC>0 40 is the signal of tissue hypoxia and can be taken as an index of emergency.This method is simple,divect,sensitive and reliable.
