摘要:
目的 探讨呼吸机吸入端不同湿化温度对ICU呼吸机相关性肺炎(VAP)的预防效果。 方法 选取2017年6月至2018年6月张家港市中医医院ICU收治的行呼吸机通气治疗患者120例为观察对象,根据随机数字表分为A组、B组、C组,每组各40例。A组的呼吸机吸入端端口的温度设置为32.0~33.9 ℃,B组设置为34.0~35.9 ℃,C组设置为36.0~37.0 ℃,比较不同组别患者使用呼吸机3 d后痰液黏稠度、痰痂形成率、刺激性咳嗽次数、呼吸机相关性肺炎(VAP)发生率、肺部湿罗音消失时间、机械通气时间、入住ICU时间、平均住院时间及患者治疗满意率。 结果 C组痰液黏稠度较A组、B组明显降低(P<0.05),痰痂形成率、VAP发生率低于A组、B组(P<0.05),而患者治疗满意率高于A组、B组(P<0.05)。C组肺部湿罗音消失时间、机械通气时间、入住ICU时间、平均住院时间均短于A组、B组(P<0.05)。 结论 将呼吸机吸入端湿化温度控制为36.0~37.0 ℃有助于改善ICU机械通气患者痰液黏稠度,避免痰痂形成,降低VAP发生率,利于患者尽早撤机及改善预后,提高患者治疗满意率。

Abstract:
Objective To investigate the preventive effect of ICU ventilator with different humidification temperature on ventilatorassociated pneumonia(VAP). Methods From June 2017 to June 2018, 120 cases receiving ventilation treatment in the ICU of Zhangjiagang Hospital of Traditional Chinese Medicine were selected and randomly divided into three groups equally. The port temperatures of the three groups were set to 32339 ℃(group A), 34359 ℃(group B) and 3637 ℃(group C) respectively. After the using of respirator for 3 days, the rates of sputum scab formation, numbers of irritating coughs, incidences of VAP, elapsed time of moist rales disappearance, mechanical ventilation time, ICU stays, average length of stay and treatment satisfaction rate were compared among the 3 groups. Results The sputum viscosity of group C was lower than that of group A and group B (P<0.05). The rates of sputum formation and VAP of group C were lower than those of group A and group B (P<005). And the treatment satisfaction rate of group C was higher than that of group A and group B (P<0.05). The elapsed time of moist rales disappearance, mechanical ventilation time, ICU stays, and average hospital stays of group C were shorter than those of group A and B (P<0.05). Conclusions Setting the humidification temperature of the inhaler end of the ventilator to be at 36-37 ℃ can improve the sputum viscosity of ICU mechanical ventilation patients, avoid the formation of sputum, reduce the incidence of VAP, and facilitate the early withdrawal and prognosis of patients, which improves the satisfaction rates of patients.
