摘要
目的探讨密闭式吸痰(closed suction system,CSS)与开放式吸痰(open suction system,OSS)在早产儿机械通气中的应用效果。方法将87例机械通气的早产儿分为观察组(CSS吸痰)45例和对照组(OSS吸痰)42例,观察两组患儿吸痰前后血氧饱和度变化、住院时间、机械通气时间及痰病原学检查结果。结果观察组在上机时间、吸痰后即刻氧饱和度、住院时间等方面结果明显优于对照组,撤机后气管插管残端细菌培养阳性率低于对照组,差异有统计学意义(P<0.05)。结论机械通气的早产儿应用CSS吸痰对血氧饱和度影响较小,减少了机械通气时间、住院时间,可有效降低气管导管残端细菌培养阳性率。
Objective We conducted this study to investigate the effectiveness of closed suction system （CSS） and open suc- tion system （OSS） in mechanical ventilation for premature infants, thereby providing evidence for the optimal choices of clinical sputum aspiration. Methods We randomly divided 87 premature infants into two groups ： CSS group （ n = 45 ） and 0SS group （ n = 42）. The changes in oxygen saturation （SpO2 ） before and after sputum aspiration, hospitalization time, ventilation time and sputum examination were compared between the two groups. Results The outcome of the OSS group was superior to the CSS group in ventilation time, SpO2 immediately after sputum aspiration, hospitalization time, and positive incidence of catheter end sputum cultivation （ P 〈 0. 05 ）. Con- clusion CSS application in mechanical ventilation for premature infants causes less fluctuation in SpO2 , reduces the ventilation time and hospitalization time, and significantly decreases positive incidence of catheter end sputum cultivation.
