目的探讨俯卧位通气对合并急性呼吸衰竭(ARF)的老年重症肺炎患者循环和呼吸功能的影响。方法 ARF老年重症肺炎患者39例随机分为俯卧位通气(A组,20例)及仰卧位通气(B组,19例),比较两组部分循环和呼吸指标。结果 A组第1、3、5天氧合指数(OI)明显高于治疗前和B组(P<0.05),第3、5天肺静态顺应性(Cst)低于治疗前和B组(P<0.05)。A组患者气管插管和住ICU时间较B组短,脱机拔管成功率高(P<0.05)。两组治疗前后的HR、MAP、CVP和心脏指数(CI)均无统计学差异(P>0.05)。结论俯卧位通气可有效改善合并ARF老年重症肺炎患者通气功能,缩短气管插管和住ICU时间。
Objective To investigate the effects of prone position ventilation on circulatory and respiratory function in elderly patients with severe pneumonia complicated with acute respiratory failure (ARF). Methods Thirty-nine patients with ARF aged severe pneumonia were randomly divided into prone position ventilation (group A, n = 20) and supine position ventilation (group B, n = 19). The circulatory and respiratory parameters were compared between the two groups. Results Oxygenation index (OI) on day 1, 3, and 5 of group A was significantly higher than that before treatment and group B (P <0.05). On day 3 and 5, lung static compliance (Cst) was lower than that before treatment and group B P <0.05). The duration of tracheal intubation and ICU stay in group A was shorter than that in group B, and the success rate of extubation was high (P <0.05). The HR, MAP, CVP and cardiac index (CI) of the two groups before and after treatment showed no significant difference (P> 0.05). Conclusions Prone ventilation can effectively improve the ventilatory function and shorten the time of tracheal intubation and ICU in patients with acute severe pneumonia complicated with ARF.
