目的 探讨翻身床俯卧位联合冲洗式吸痰在重度吸入性损伤机械通气患者中的应用效果。方法 采用便利抽样法选取2021年3月至2023年3月苏州市某三级甲等医院烧伤整形科收治的重度吸入性损伤行机械通气的患者为研究对象，按入院先后将其分为对照组（n=30）和观察组（n=26），分别采用仰卧位冲洗式吸痰法、翻身床俯卧位联合冲洗式吸痰。结果 观察组的吸痰有效率、氧合指数方面均优于对照组，呼吸道内炭末样沉着消失所用时间及气管套管拔除时间短于对照组（均P＜0.05）。结论 翻身床俯卧位联合冲洗式吸痰能有效提高重度吸入性损伤机械通气患者的吸痰有效率、氧合指数，缩短呼吸道内炭末样沉着消失及气管套管拔除的时间，建议推广应用。

Objective To explore the application effects of prone position flushing sputum aspiration in rollover beds for mechanically ventilated patients with severe inhalation injuries.Methods Convenient sampling method was used to select mechanically ventilated patients with severe inhalation injuries in the Department of Burn and Plastic Surgery in a tertiary hospital in Suzhou from March 2021 to March 2023.According to the time of admission,they were divided into the control group (n=30) and the observation group (n=26) and were respectively treated in supine position and in prone position in rollover beds.Results The observation group was better than the control group in the effective rate of sputum aspiration and oxygenation index.The time taken for the disappearance of charcoal deposits in the respiratory tract and for tracheal cannula removal in the observation group were shorter than those in the control group (all P＜0.05).Conclusions The prone position flushing sputum aspiration in rollover beds can improve the efficiency of sputum aspiration for mechanically ventilated patients with severe inhalation injuries,improve the oxygenation index,speed up the disappearance of charcoal deposits in the respiratory tract,and shorten the time of tracheal cannula removal,which is worthy of clinical promotion.
