Airway management is a critical component of out-of-hospital cardiac arrest (OHCA) resuscitation. The primary aim of this study was to describe pre-hospital airway management in adult patients post-OHCA. Secondary aims were to investigate whether tracheal intubation (TI) versus use of supraglottic airway device (SGA) was associated with patients' outcomes, including ventilator-free days within 26 days of randomization, 6 months neurological outcome and mortality.
Secondary analysis of the Target Temperature Management-2 (TTM2) trial conducted in 13 countries, including adult patients with OHCA and return of spontaneous circulation, with data available on pre-hospital airway management. A multivariate logistic regression model with backward stepwise selection was employed to assess whether TI versus SGA was associated with outcomes.
Of the 1900 TTM2 trial patients, 1702 patients (89.5%) were included, with a mean age of 64 years (Standard Deviation, SD = 13.53); 79.1% were males. Pre-hospital airway management was SGA in 484 (28.4%), and TI in 1218 (71.6%) patients. At hospital admission, 87.8% of patients with SGA and 98.5% with TI were mechanically ventilated (p < 0.001). In the multivariate analysis, TI in comparison with SGA was not independently associated with an increase in ventilator-free days within 26 days of randomization, improved neurological outcomes, or decreased mortality. The hazard ratio for mortality with TI vs. SGA was 1.06, 95%Confidence Interval (CI) 0.88-1.28, p = 0.54.
In the multicentre randomized TTM2-trial including patients with OHCA, most patients received prehospital endotracheal intubation to manage their airway. The choice of pre-hospital airway device was not independently associated with patient clinical outcomes.

气道管理是院外心脏骤停（OHCA）复苏的一个关键组成部分。本研究的主要目的是描述 OHCA 后成年患者的院前气道管理。次要目的是研究气管插管（TI）与使用声门上气道装置（SGA）是否与患者的预后相关，包括随机分组后 26 天内无呼吸机天数、6 个月的神经功能结局和死亡率。
在 13 个国家进行的目标温度管理-2（TTM2）试验的二次分析，纳入 OHCA 并恢复自主循环的成年患者，且有院前气道管理的数据。采用向后逐步选择的多变量逻辑回归模型来评估 TI 与 SGA 是否与结局相关。
在 1900 例 TTM2 试验患者中，纳入了 1702 例患者（89.5%），平均年龄为 64 岁（标准差[SD]为 13.53）；79.1%为男性。院前气道管理中，484 例患者使用 SGA（28.4%），1218 例患者使用 TI（71.6%）。入院时，使用 SGA 的患者中有 87.8%，使用 TI 的患者中有 98.5%接受了机械通气（p < 0.001）。多变量分析中，与 SGA 相比，TI 并不独立增加随机分组后 26 天内无呼吸机天数、改善神经功能结局或降低死亡率。与 SGA 相比，TI 死亡率的危险比为 1.06，95%置信区间（CI）为 0.88-1.28，p = 0.54。
在包括 OHCA 患者的多中心随机 TTM2 试验中，大多数患者接受了院前气管插管来管理气道。院前气道设备的选择与患者的临床结局无关。
