目的探讨不同人工气道气囊滞留物清除术对重症监护病房(ICU)呼吸机相关性肺炎的影响。方法选取2013年4月至2014年3月在广东省中山市博爱医院接受呼吸机辅助通气治疗的90例患者为研究对象,按随机数字表法分为观察组和对照组,每组45例,观察组进行滞留物间断持续引流法,对照组在患者血氧饱和度降低或肺部听诊出现痰鸣音时吸除痰液,比较两组患者呼吸机相关性肺炎的发生率、机械通气时间及住院时间。结果观察组患者的呼吸机相关性肺炎发生率为6.7%(3/45),显著低于对照组的40.0%(18/45),差异有统计学意义(P<0.05);观察组患者的机械通气时间及住院时间显著短于对照组,差异均有统计学意义(均P<0.05)。结论呼吸机辅助通气患者进行间断持续引流清除气囊上方的滞留物,可显著降低呼吸机相关性肺炎的发生率,促进患者病情迅速康复,临床效果确切。
Objective To investigate the effect of different artificial airway balloon debridement on ventilator-associated pneumonia in intensive care unit (ICU). Methods From April 2013 to March 2014, 90 patients undergoing ventilator-assisted ventilation in Pok Oi Hospital of Zhongshan City, Guangdong Province were selected as study objects, divided into observation group and control group by random number table method, with 45 cases in each group. The patients in the observation group were treated with intermittent continuous retentate drainage. The control group was sputum aspirated when the patient’s blood oxygen saturation decreased or the auscultation of the lung was exhaled. The incidence of ventilator-associated pneumonia and the duration of mechanical ventilation were compared between the two groups Hospitalization time. Results The incidence of ventilator-associated pneumonia in the observation group was 6.7% (3/45), significantly lower than that in the control group (40.0%, 18/45) (P 0. 05) Mechanical ventilation time and hospitalization time were significantly shorter than the control group, the differences were statistically significant (P <0.05). CONCLUSIONS: Continuous intermittent drainage of patients with ventilator-assisted ventilation to remove the retentate above the balloon can significantly reduce the incidence of ventilator-associated pneumonia and promote the rapid recovery of patients’ condition. The clinical effect is definite.
