摘  要:目的 探讨不同潮气量通气对呼吸衰竭患者右心功能的影响。方法 选2015年6—12月河北医科大学第四医院重症医学科收治的呼吸衰竭且行有创正压机械通气治疗满24 h的患者,将患者分为急性呼吸窘迫综合征(ARDS)组、非ARDS组,ARDS组患者给予小潮气量(≤6 ml/kg标准体重)和大潮气量(〉6 ml/kg标准体重),非ARDS组患者给予小潮气量(≤8 ml/kg标准体重)和大潮气量(〉8 ml/kg标准体重)。心脏超声观测所有患者正压通气前后右心室舒张末期面积/左心室舒张末期面积(RVarea/LVarea)、三尖瓣环根部侧壁收缩期位移(TAPSE)等。评估不同潮气量对右心功能、机械通气时间、ICU留治时间、总住院时间和28 d病死率的影响。结果 共入选患者84例,ARDS组43例,其中小潮气量者19例,大潮气量者24例;非ARDS组41例,其中小潮气量者24例,大潮气量者17例。随机械通气时间延长,2组患者TAPSE进行性下降[ARDS组小潮气量者由18.30(16.70,20.70) mm降至17.55(15.70,19.50) mm;大潮气量者由19.50(17.00,21.00) mm降至16.30(15.00,18.00) mm,P=0.001。非ARDS组小潮气量者由18.00(16.00,21.00) mm降至16.50(15.50,18.00) mm;大潮气量者由19.00(17.50,21.50) mm降至16.35(15.15,17.00) mm,P=0.001],差异有统计学意义。ARDS组大小潮气量者间与非ARDS组大小潮气量者间TAPSE差异无统计学意义,但大潮气量者TAPSE下降更明显。ARDS组小潮气量者28 d病死率较大潮气量者降低[1/19比37.5%(9/24), P〈0.05]。非ARDS组大小潮气量者间28 d病死率差异无统计学意义(P〉0.05)。ARDS组和非ARDS组大小潮气量者间ICU留治时间、总住院时间、机械通气时间差异均无统计学意义(P值均〉0.05)。logistic回归分析显示,潮气量可能是影响TAPSE的独立因素,OR=1.104,95% CI 0.100~1.003,P=0.049。结论 正压通气可使右�Objective To observe and explore the effects of different tidal volume (VT) ventilation on right ventricular (RV) function in patients with critical respiratory failure.Methods Consecutive respiratory failure patients who were treated with invasive ventilator over 24 h in the Department of Critical Care Medicine at the Fourth Hospital of Hebei Medical University from June to December in 2015 were enrolled in this study.Clinical data including patients′ vital signs, ventilator parameters and RV echocardiography were collected within 6 h (D0), day1(D1), day2 (D2) and day3 (D3) after ventilation started.According to the VT, patients with acute respiratory distress syndrome (ARDS) were assigned to low VT group [S6, ≤6 ml/kg predicted body weight (PBW)] and high VT group (L6, 〉6 ml/kg PBW), while non-ARDS patients were also assigned to low VT group (S8, ≤8 ml/kg PBW) and high VT group (L8, 〉8 ml/kg PBW).Results A total of 84 patients were enrolled in this study.44.2% ARDS patients and 58.5% non-ARDS patients were in low VT groups.After ventilation, tricuspid annulus plane systolic excursion(TAPSE)decreased progressively in S6 [from 18.30(16.70, 20.70) mm to 17.55(15.70, 19.50) mm, P=0.001], L6 [from 19.50(17.00, 21.00) mm to 16.30(15.00, 18.00) mm P=0.001], S8[from 18.00(16.00, 21.00) mm to 16.50(15.50, 18.00) mm, P=0.001] and L8 [from 19.00(17.50, 21.50) mm to 16.35(15.15, 17.00) mm, P=0.001] groups.However, TAPSE decreased less in small VT groups (S6 and S8) than those of in large VT groups (S8 and L8) without significant differences.There were not statistical differences between different VT groups in terms of ventilation days, including right ventricle area/left ventricle area (RVarea/LVarea), TAPSE, peak mitral flow velocity of the early rapid filling wave (E), peak mitral flow velocity of the late rapid filling wave (A), early diastolic velocity of the tricuspid annulus (e′), pulmonary artery systo
