摘要 [目的]探讨定时与按需膨肺吸痰法对机械通气病人的影响。[方法]将120例行机械通气的病人,随机分为对照组、定时膨肺吸痰组和按需膨肺吸痰组,按时膨肺吸痰组8h1次用膨肺吸痰法吸痰,定需膨肺吸痰组根据病人需要用膨肺吸痰法吸痰,对照组每日按常规吸痰,观察吸痰前、吸痰后3min氧合指数、呼吸末二氧化碳分压(PETCO2)、生理无效腔/潮气量(Vd/Vt)、气道阻力、气道压力、平台压等呼吸功能参数以及心率、血压、血氧饱和度变化,治疗5d内累计总吸痰次数,肺不张发生率。[结果]定时膨肺吸痰组和按需膨肺吸痰组吸痰前后参数、总吸痰次数、肺不张发生率与对照组比较有统计学意义(P<0.01),但定时膨肺吸痰组和按需膨肺吸痰组比较差异无统计学意义(P>0.05)。[结论]膨肺吸痰法可改善肺通气或换气功能,保证生命体征的稳定,防止肺不张的发生,减少吸痰次数。
