Targeted temperature management at 36°C is a risk factor for ventilator‐associated pneumonia

Abstract

AbstractBackgroundIn contrast to the adult population, limited information is currently available on risk factors for ventilator‐associated pneumonia (VAP) in children. Therapeutic hypothermia has been identified as a risk factor for the early onset of VAP in adults; however, the relationship between VAP and normothermia remains unclear. The present study investigated risk factors for VAP in children, with a focus on the deleterious effects of therapeutic normothermia on VAP.MethodsWe retrospectively investigated the clinical characteristics of children treated with mechanical ventilation for more than 48 h and analyzed risk factors for VAP. The endpoint was the onset of VAP by the seventh day after the initiation of mechanical ventilation.ResultsAmong the 288 patients enrolled, seven (2.4%) developed VAP. No significant differences were observed in clinical backgrounds between the VAP and non‐VAP groups. A univariate analysis identified target temperature management (TTM) at 36°C (p < 0.0001) and methylprednisolone (mPSL) pulse therapy (p = 0.02) as risk factors for VAP. An analysis of the time to the onset of VAP by the Kaplan–Meier plot and log‐rank test revealed a significantly higher incidence of VAP in the TTM group (p < 0.0001) and mPSL pulse group (p = 0.001).ConclusionTTM at 36°C and mPSL pulse therapy may be risk factors for VAP in the pediatric population.
