【摘要】 目的　探讨小潮气量低分钟通气治疗对外伤性急性呼吸窘迫综合征 (ARDS)预后的影响。方法　 4 6例外伤性ARDS随机分为常规通气治疗组 (n =2 6 )和小潮气量组 (n =2 0 ) ,常规通气治疗组的潮气量为 10～ 15ml/kg ,小潮气量组为 6～ 8ml/kg ;比较两组的预后及并发症。 结果　小潮气量组的病死率显著低于常规通气组 ,气压伤及低血压的发生率也显著低于常规通气组。结论　小潮气量低分钟通气治疗ARDS能显著降低通气机所致的肺损伤及对循环的影响 ,显著降低病死率 ,值得推广应用。更多还原

【Abstract】 Objective To explore the effect of low tidal volume and minute ventilation mechanical ventilation on prgnosis of tramatic ARDS.Methods Fourty-six cases tramatic ARDS were divided into routine ventilation group(26 cases) and low tidal volume group(20 cases) randomly.The tidal volume in routine ventilation group was 10～15ml/kg,and that in low tidal volume group was 6～8ml/kg during mechanical therapy.The prognosis and complications between the two groups were compared.Results The mortality in low tidal volume group was lower than that of routine ventiation group significantly.The incidence of pulmonary injury and hypotention was also lower than that of routine ventilation group significantly.Conclusion Low tidal volume and minute ventilation therapy could decline the pulmonary injury caused by ventilator and the incidence of hypotention significantly.The mortality rate was decreased obviously.It was valuable for widely using.更多还原
