舒氧康静脉给氧预防术后低氧血症

Prevent postoperative hypoxemia with oxygenator by intravenous oxygen delivery

目的 探讨舒氧康静脉给氧对老年病人术后早期低氧血症的防治效果。方法 40例行腹部手术的老年患者 ,随机分为对照组 (Ⅰ组 ) 2 0例和实验组 (Ⅱ组 ) 2 0例。Ⅰ组病人从离开手术室到转送回病房共 2 0分钟不吸氧 ;Ⅱ组病人离开手术室即开始在平衡盐液中使用舒氧康以 6ml/kg ,输注速度为 0 3ml/ (kg·min)进行输液给氧。两组病人均应用脉搏血氧饱和度监测仪连续动态监测SpO2 。比较两组的脉搏血氧饱和度 (SpO2 )、血压 (BP)、心率 (HR)并进行统计学分析。结果 对照组 (Ⅰ组 )脉搏血氧饱和度 (SpO2 )明显低于实验组 (Ⅱ组 ) (P <0 0 5 ) ,两组生命体征比较无显著性差异 (P >0 0 5 )。结论 在手术后转送病房途中 ,由于不具备吸氧条件 ,老年病人容易发生低氧血症 ,舒氧康可以维持SpO2 值 。

Objective To observe the preventive effect of early postoperative hypoxemia in aged patients with oxygenator by intravenous oxygen delivery.Methods 40 aged patients with abdominal surgery were divided into 2 groups,control group(group 1) 20 patients and experimental group(group 2)20 patients.The patients of group 1 breathing with the air twenty minute during the transport,the patients of group 2 were oxygen infused with oxygenator 6ml/kg in Ringer solution when left the operating room,the speed was 0.3ml/(kg.min).The trends of continuous arterial oxygen saturation were monitored by pulse oximetry.Compared the SpO2,BP and HR of two groups,and analyzed by T test.Results SpO2 of group 1 was decreased significantly than group 2(P<0.05),and there was no change of vital signs in group 1 and 2(P>0.05).Conclusion Postoperative hypoxemia often occurred in aged patients on the way to ward,because there was no condition of oxygen inhalation.Oxygenator could keep the number of SpO2,and prevent the occurrence of postoperative hypoxemia.
