Epidemiology, ventilator management, and outcome in patients receiving invasive ventilation in intensive care units (ICUs) in middle-income countries are largely unknown. PRactice of VENTilation in Middle-income Countries is an international multicenter 4-week observational study of invasively ventilated adult patients in 54 ICUs from 10 Asian countries conducted in 2017/18. Study outcomes included major ventilator settings (including tidal volume [V T ] and positive end-expiratory pressure [PEEP]); the proportion of patients at risk for acute respiratory distress syndrome (ARDS), according to the lung injury prediction score (LIPS), or with ARDS; the incidence of pulmonary complications; and ICU mortality. In 1,315 patients included, median V T was similar in patients with LIPS < 4 and patients with LIPS ≥ 4, but lower in patients with ARDS (7.90 [6.8-8.9], 8.0 [6.8-9.2], and 7.0 [5.8-8.4] mL/kg Predicted body weight; P = 0.0001). Median PEEP was similar in patients with LIPS < 4 and LIPS ≥ 4, but higher in patients with ARDS (five [5-7], five [5-8], and 10 [5-12] cmH2O; P < 0.0001). The proportions of patients with LIPS ≥ 4 or with ARDS were 68% (95% CI: 66-71) and 7% (95% CI: 6-8), respectively. Pulmonary complications increased stepwise from patients with LIPS < 4 to patients with LIPS ≥ 4 and patients with ARDS (19%, 21%, and 38% respectively; P = 0.0002), with a similar trend in ICU mortality (17%, 34%, and 45% respectively; P < 0.0001). The capacity of the LIPS to predict development of ARDS was poor (receiver operating characteristic [ROC] area under the curve [AUC] of 0.62, 95% CI: 0.54-0.70). In Asian middle-income countries, where two-thirds of ventilated patients are at risk for ARDS according to the LIPS and pulmonary complications are frequent, setting of V T is globally in line with current recommendations.
在中低收入国家的重症监护病房（ICU）中，接受有创通气的患者的流行病学、通气管理和结局在很大程度上尚不清楚。中低收入国家的通气实践（PRactice of VENTilation in Middle-income Countries，PROVENT）是一项国际性、多中心、观察性研究，纳入了 2017/18 年期间来自亚洲 10 个国家的 54 个 ICU 中 1315 例接受有创通气的成年患者。研究结局包括主要通气设置（包括潮气量[V T ]和呼气末正压[PEEP]）；根据肺损伤预测评分（LIPS）预测有急性呼吸窘迫综合征（ARDS）风险或患有 ARDS 的患者比例；肺部并发症发生率；以及 ICU 死亡率。在纳入的 1315 例患者中，LIPS<4 的患者和 LIPS≥4 的患者的 V T 中位数相似，但 ARDS 患者的 V T 较低（分别为 7.90[6.8-8.9]、8.0[6.8-9.2]和 7.0[5.8-8.4]mL/kg 预测体重；P=0.0001）。LIPS<4 的患者和 LIPS≥4 的患者的 PEEP 中位数相似，但 ARDS 患者的 PEEP 较高（分别为 5[5-7]、5[5-8]和 10[5-12]cmH2O；P<0.0001）。LIPS≥4 或 ARDS 的患者比例分别为 68%（95%CI：66-71）和 7%（95%CI：6-8）。肺部并发症发生率逐渐升高，依次为 LIPS<4 的患者、LIPS≥4 的患者和 ARDS 患者（分别为 19%、21%和 38%；P=0.0002），ICU 死亡率也呈现类似趋势（分别为 17%、34%和 45%；P<0.0001）。LIPS 预测 ARDS 发生的能力较差（ROC 曲线下面积[AUC]为 0.62，95%CI：0.54-0.70）。在亚洲中低收入国家，根据 LIPS，三分之二的接受通气的患者有患 ARDS 的风险，肺部并发症较为常见，V T 的设定与当前的推荐一致。
