摘　　要：目的评价适应性支持通气(ASV)模式加肺复张策略(LRM)在急性呼吸窘迫综合征(ARDS)患者中的效果。方法收集创伤后合并ARDS的患者28例,先采用间歇正压通气(IPPV)模式维持8 h后,随机选择ASV或继续IPPV机械通气。选择ASV通气模式时,其分钟通气量设置应与IPPV时相同。通气时,两种模式下的呼气末正压(PEEP)均按0、5、10cmH2O依次增加,每一PEEP的通气时间为60 m in。ASV通气模式时,在每一PEEP水平加用LRM(ASV+LRM模式)。前一通气模式使用3h后,将通气模式调为IPPV,PEEP调到0;1h后换另一种模式。每个PEEP水平通气50 m in时,用Swan-Ganz导管、心电监测仪、呼吸机监测记录患者的血流动力学、呼吸力学和氧代谢指标。结果在同一PEEP水平下,ASV+LRM模式与IPPV模式相比较,血流动力学参数差异无统计学意义(P>0.05);但在ASV+LRM模式时,同一PEEP水平下气道峰值压(PIP)降低,差异有统计学意义(P<0.05);当PEEP为5cmH2O时,肺动态顺应性、动脉氧分压和氧供均增加,差异也有统计学意义(P<0.05)。结论 ASV+LRM模式比IPPV模式更有利于ARDS患者的通气治疗。Objective To investigate the effects of adaptive support ventilation（ASV） plus lung recruitment maneuvers（LRM） on acute respiratory distress syndrome（ARDS）. Methods Twenty-eight patients with ARDS after trauma were collected,and were randomly treated with ASV or intermittent positive pressure ventilation（IPPV） after management with IPPV for 8 h.The minute ventilation in ASV was the same with IPPV.Positive end expiratory pressure（PEEP） level increased in each model by 0,5 and 10 cmH2O,and each level of PEEP was maintained for 60 min.LRM was added to each PEEP level in ASV model（ASV＋LRM model）.Three hours after the previous ventilation model,it was adjusted to IPPV with 0 cmH2O PEEP,then to the other model 1 h later.Hemodynamics,respiratory mechanics and oxygen metabolism parameters were measured with Swan-Ganz catheter,electrocardiogram monitor and breathing machine after patients were ventilated with each level of PEEP for 50 min. Results Under the same PEEP level,there was no significant difference in hemodynamic parameters between ASV＋LRM model and IPPV model（P〉0.05）,while the peak inspiratory pressure in ASV＋LRM model was significantly lower than that in IPPV model（P〈0.05）,and lung dynamic compliance,partial pressure of oxygen in artery and oxygen delivery in ASV＋LRM model were significantly higher than those in IPPV model with PEEP=5 cmH2O（P〈0.05）. Conclusion ASV＋LPS model is better than IPPV in ventilation for patients with ARDS.
