目的:探讨不同通气给氧技术对小儿气管异物取出术的临床效果。方法:40例行气管异物取出术患儿随机分为使用肌松药的高频喷射通气组(Ⅰ组)和保留自主呼吸组(Ⅱ组)各20例,比较两组手术时间、苏醒时间和术中、术后各时点生命体征变化,并比较术中、术后并发症发生率。结果:Ⅰ组患儿在置镜、术中、退镜时点上的平均动脉压及心率显著低于Ⅱ组(P<0.05),而且血氧饱和度显著高于Ⅱ组(P<0.05),且Ⅰ组患儿术中、术后并发症发生例数<Ⅱ组(P<0.05)。结论:使用肌松药的正压通气能维持术中呼吸、循环稳定、麻醉平稳,有利于手术操作,是手术成功的重要因素。
Objective: To investigate the clinical effects of different ventilation and oxygenation techniques on pediatric tracheal foreign bodies removal. Methods: Forty children with tracheal foreign body removal were randomly divided into high frequency jet ventilation group (group Ⅰ) and spontaneous breathing group (group Ⅱ) with muscle relaxants of 20 cases. The operation time, recovery time and During and after surgery, the vital signs were changed at different time points and the intraoperative and postoperative complication rates were compared. Results: The average arterial pressure and heart rate of group Ⅰ were significantly lower than those of group Ⅱ (P0.05), and the oxygen saturation of group Ⅰ was significantly higher than that of group Ⅱ (P0.05) , And the incidence of intraoperative and postoperative complications in group I was less than that in group II (P <0.05). Conclusion: Positive pressure ventilation with muscle relaxants can maintain intraoperative respiration, stable circulation, stable anesthesia, and favorable operation. It is an important factor for successful operation.
