摘要
目的探索不同潮气量对呼吸衰竭住院危重患者右心影响的临床研究。方法选取2015年6月—2018年6月间于永城市人民医院接受治疗的72例患者为研究对象,按照是否发生呼吸窘迫征分成观察组和对照组。对患者进行心脏超声检查,获取右、左心室舒张末期面积比值(RV/LV),三尖瓣环根部侧位收缩期位移数据。结果研究发现,观察组小潮气量为(342.15±12.35)ml,大潮气量(413.65±21.36)ml。观察组患者不同潮气量RV/LV比值均低于对照组RV/LV比值。同时观察组及对照组小潮气量TAPSE数值分别为(13.26±3.16)mm和(14.23±3.08)mm,均低于观察组及对照组大潮气量TAPSE数值。logistic回归显示,潮气量是造成呼吸衰竭患者右心功能障碍的独立危险因素。结论小通气量能够有效保护呼吸衰竭住院危重病人右心功能,且正压通气会影响患者右心功能,形成右心收缩障碍,潮气量是影响呼吸衰竭住院危重患者的独立危险因素。
Objective To explore the effect of different tidal volume on the right heart in critically ill patients with respiratory failure.Methods 72 patients in the hospital from June,2015 to June,2018 were selected for the study.According to whether the occurrence of respiratory distress syndrome,they were divided into the observation group and the control group.Echocardiography was performed to obtain the right and left ventricular end diastolic area ratio(RV/LV),and the data of the lateral systolic displacement at the apex of the three cusps.Results The study found that low tidal volume was(342.15±12.35)ml,and tidal volume was(413.65±21.36)ml in observation group.The tidal volume and RV/LV ratio in the observation group were lower than that in the control group.Small TAPSE numerical tidal volume were(13.26±3.16)mm and(14.23±3.08)mm in observation group and control group,which were lower than the big ones.Logistic regression showed that tidal volume was an independent risk factor for right heart dysfunction in patients with respiratory failure.Conclusion Small ventilation can effectively protect the right cardiac function of critically ill patients with respiratory failure,positive pressure ventilation can influence the patient’s right cardiac function.Tidal volume is the independent risk factor of critically ill patients with respiratory failure.
