Ventilator-associated pneumonia (VAP) is a common cause of morbidity and mortality for critically ill burn patients. Prevention of VAP through bundled preventative measures may reduce the risk and incidence of VAP in burn patients. A retrospective chart review was performed of all mechanically ventilated adult (age ≥ 18 years) burn patients before and after VAP prevention bundle implementation. Data collected included age, TBSA, gender, diagnosis of inhalation injury, mechanism of injury, comorbid illnesses, length of mechanical ventilation, length of hospital stay, development of VAP, discharge disposition, and mortality. Burn patients with VAP had larger burn injuries (47.6 ± 22.2 vs 23.9 ± 23.01), more inhalation injuries (44.6% vs 27%), prolonged mechanical ventilation, and longer intensive care unit (ICU) and hospital stays. Mortality was also higher in burn patients who developed VAP (34% vs 19%). On multivariate regression analysis, TBSA and ventilator days were independent risk factors for VAP. In 2010, a VAP prevention bundle was implemented in the burn ICU and overseen by a nurse champion. Compliance with bundle implementation was more than 95%. By 2012, independent of age, TBSA, inhalation injury, ventilator days, ICU and hospital length of stay, VAP prevention bundles resulted in a significantly reduced risk of developing VAP (odds ratio of 0.15). Burn patients with an inhalation injury and a large burn injury are at increased risk of developing VAP. The incidence and risk of VAP can be significantly reduced in burn patients with VAP prevention bundles.
呼吸机相关性肺炎(VAP)是重症烧伤患者发病和死亡的常见原因。通过一系列预防措施预防VAP可降低烧伤患者发生VAP的风险和发生率。对实施VAP预防措施前后所有接受机械通气的成年(年龄≥18岁)烧伤患者进行了回顾性病历审查。收集的数据包括年龄、烧伤总面积(TBSA)、性别、吸入性损伤诊断、损伤机制、合并症、机械通气时间、住院时间、VAP的发生情况、出院处置和死亡率。发生VAP的烧伤患者烧伤面积更大(47.6±22.2 vs 23.9±23.01),吸入性损伤更多(44.6% vs 27%),机械通气时间延长,重症监护病房(ICU)和住院时间更长。发生VAP的烧伤患者死亡率也更高(34% vs 19%)。多因素回归分析显示,TBSA和机械通气天数是VAP的独立危险因素。2010年,烧伤ICU实施了VAP预防措施,并由一名护士负责人监督。措施实施的依从率超过95%。到2012年,与年龄、TBSA、吸入性损伤、机械通气天数、ICU和住院时间无关,VAP预防措施使发生VAP的风险显著降低(优势比为0.15)。有吸入性损伤和大面积烧伤的烧伤患者发生VAP的风险增加。VAP预防措施可显著降低烧伤患者VAP的发生率和风险。
