Abstract： 目的评价机械通气治疗急性发作危重症哮喘的方法及疗效.方法对2001年1月至2004年11月收治的246例急性发作危重哮喘中15例危重型哮喘患者,在内科综合治疗同时13例经气管插管,起始模式为同步间歇指令通气+压力支持,应用静脉内注射肌松剂者为控制/辅助模式,低潮气量(6～8ml/kg),慢呼吸频率(10～12次/min),长呼气时间(吸:呼>1:2),吸气压<25cmH2O,吸气时间0.7～1.0秒.2例经面罩行机械通气,为双水平正压通气.结果 15例患者均抢救成功,平均1.25小时症状体征开始改善,机械通气24小时症状评分≤2分,平均机械通气时间59.8小时,治疗后血气分析指标均恢复正常,最高呼气峰流量(PEF)值显著增高(P＜0.01).结论机械通气是治疗急性发作危重症哮喘的有效方法,应注意把握适应证,适当的模式和参数.
