摘要 [目的]研究不同吸痰方式对肺不张病人呼吸循环参数的影响。[方法]选择24例肺不张并机械通气的危重病人,随机分为密闭式吸痰(CS)组和开放式吸痰(OS)组。观察两组不同方式吸痰前1min及吸痰后3min、20min呼吸(RR)、心率(HR)、收缩压(SBP)、舒张压(DBP)、脉搏血氧饱和度(SpO2)、气道峰压(Ppeak)、平台压(Pplat)、潮气量(Vt)及pH值、氧分压(PaO2)、二氧化碳分压(PaCO2)的变化。[结果]OS组吸痰后3min与吸痰前1min比较,SBP、HR、RR、Ppeak、Pplat增高(P<0.05),SpO2、PaO2下降(P<0.05);OS组吸痰后20min与吸痰前1min比较,RR仍增高(P<0.05),PaO2下降(P<0.05);CS组吸痰前后上述各参数比较差异无统计学意义(P>0.05);与CS组同时段比较,OS组SBP、HR、RR、Ppeak、Pplat增高(P<0.05),SpO2、PaO2下降(P<0.05)。[结论]肺不张病人使用CS能较好地维持机体氧合状态,保持循环参数及气道压力的相对稳定。
