2种拔管法在婴幼儿心内直视手术后撤离机械通气中的应用

The Application of Two Ways of Extubation from Mechanical Ventilation' in Infants after Open-heart Surgery

目的比较婴幼儿心内直视手术后撤离机械通气的不同拔管方法的效果。方法将90例心内直视手术后机械通气的婴幼儿随机分成干预组(45例)和对照组(45例)。干预组实施镇静撤机法,对照组实施清醒撤机法。比较2组患儿拔管时的通气状况。结果干预组患儿在拔管过程中出现心率增快、烦躁、收缩压升高的例数较对照组少(p均<0.05)。结论镇静撤机法有利于使患儿保持安静,减轻拔管的刺激,有利于改善心、肺功能,值得临床推广应用。

Objective： To compare the effect of two ways of exmbation to mechanical ventilation＇evacuation in infants after open-heart surgery. Methods： 90 infants after open-heart surgery were randomly divided into control group （n1=45） and intervention group （n2=45）. The infants in intervention group were extubated from mechanical ventilation with sedative, while the infants in control group were extubated when they were awake. The status of infants were compared with the two groups when they were extubated from mechnical ventilation. Results： There were fewer infants in intervention group who had higher heart rate, more impatience, and higher systolic blood pressure, compared with the control group （all ps〈0.05）. Conclusion： Extubation from mechanical ventilation with sedative could help keep the infants quiet, relieve stimulus, and improve cardiac function and pulmonary function. It should be widely used in clinical settings.
