【摘要】 目的　研究保护性机械通气对肺挫伤治疗结局的影响。方法　将 44例严重肺挫伤患者分为两组 :保护性通气组 2 1例 ,传统通气组 2 3例。保护性通气组潮气量采用 6～ 8ml/kg ,传统通气组为 12～ 15ml/kg ,其它呼吸机参数按同一策略调整 ,比较两组间呼吸机使用天数及ARDS、肺部感染等并发症的发生率。结果　保护性通气组机械通气治疗天数及肺部感染率较传统通气组明显缩短 (P <0 .0 5 ) ,且ARDS的发生率低于传统通气组 ,但无统计学意义 (P >0 .0 5 )。结论　保护性机械通气能减少肺挫伤患者呼吸机使用天数并降低肺部感染率 ,临床上值得推广。更多还原

【Abstract】 Objective To study the effect of protective ventilation strategy on severe plumonary contusion.Methods 44 patients suffered from pulmonary contusion were divided into two groups:protective ventilation group (n=21);traditional ventilation group(n=23).The tidal volumes in the protective ventilation was 6～8ml/kg,and that in the traditional ventilation group was 12～15ml/kg.The days for ventilator therapy and the morbidity of pulmonary infection and ARDS were compared between the two groups.Results The days for ventilation therapy was obviously shorter in protective ventilation group than that in traditional ventilation groups and the morbidity of pulmonary infection was lower.The morbidity of ARDS was not significant difference between the two groups. Conclusion Protective ventilator therapy for pulmonary contusion could markedly reduce the time for ventilator therapy and lower the morbidity of pulmonary effection.更多还原
