  • The Role of Maintaining Constant Pressure of the Endotracheal Catheter Cuff in Prevention of Ventilator-associated Pneumonia

    ObjectiveTo explore the preventive role of maintaining constant pressure of the endotracheal catheter cuff on ventilator-associated pneumonia (VAP). MethodsFrom January to December 2015, 96 patients of type Ⅱ respiratory failure were selected as the trial group who underwent intubation and mechanical ventilation more than 48 hours in the Intensive Care Unit (ICU). We used pressure gauges to measure the endotracheal catheter cuff pressure regularly and maintained a constant pressure in addition to the application of artificial airway cluster management. We recorded the initial pressure value which was estimated by pinching with finger and set initial pressure to 30 cm H2O (1 cm H2O=0.098 kPa). We measured endotracheal catheter cuff pressure and recorded it during different intervals. We reviewed 88 patients with the same disease as the control group who only accepted artificial airway cluster management between January and December 2014. Mechanical ventilation time, VAP occurrence time, ICU admission time, the incidence of VAP were recorded and analyzed for both the two groups of patients. ResultsIn the trial group, the initial pressure of endotracheal catheter cuff which was estimated by pinching with finger showed that only 11.46% of pressure was between 25 and 30 cm H2O and 82.29% of the pressure was higher than 30 cm H2O. We collected endotracheal catheter cuff pressure values during different interval time by using pressure gauges to maintain a constant management. The ratio at the pressure between 25 and 30 cm H2O was respectively 41.32%, 43.75%, 64.20%, 76.54%, 91.13%, and 91.85%. ICU admission time, mechanical ventilation time in patients of the trial group decreased more, compared with the control group, and the differences were statistically significant (t=4.171, P<0.001; t=4.061, P<0.001). The VAP occurrence time in patients of the trial group was later than the control group (t=2.247, P<0.001). ConclusionThe endotracheal catheter cuff pressure estimated by pinching with finger has errors. We recommend using pressure gauges to detect pressure every four hours, which utilizes minimal time to maintain effective pressure. The method of artificial airway of cluster management combined with the pattern of maintaining constant endotracheal catheter cuff pressure can shorten ICU admission time, mechanical ventilation time and delay the occurrence of VAP.

  • 无创正压机械通气治疗支气管扩张症合并呼吸衰竭的回顾性分析

    目的观察支气管扩张症合并呼吸衰竭患者应用无创正压机械通气(NPPV)治疗前后各项生理指标的变化,评价其疗效。 方法选择2010年1月至2011年12月华北油田公司总医院收治的应用无创正压机械通气治疗的支气管扩张症合并呼吸衰竭患者36例,比较治疗前后患者的心率、呼吸频率(RR)、pH值、动脉血二氧化碳分压(PaCO2)、动脉血氧分压(PaO2)、氧合指数(PaO2/FiO2)、辅助呼吸肌评分、呼吸困难分级、第1秒用力呼气容积占预计值百分比(FEV1%pred)、第1秒用力呼气容积/用力肺活量比值(FEV1/FVC)、插管率和病死率。 结果经无创正压机械通气治疗后,患者的心率、RR、PaCO2、辅助呼吸肌评分和呼吸困难分级均明显下降,pH值、PaO2、PaO2/FiO2、FEV1%pred、FEV1/FVC均明显上升,与治疗前比较差异具有统计学意义(P<0.05)。2例患者因病情恶化行有创机械通气治疗,插管率5.56%,其中1例患者死亡。 结论合理选择应用NPPV可以改善支气管扩张症合并呼吸衰竭患者的肺通气功能。
