Prophylactic versus clinically-driven antibiotics in comatose survivors of out-of-hospital cardiac arrest—A randomized pilot study
2017
Abstract Aim To investigate benefits of prophylactic antibiotics in comatose survivors of out-of-hospital cardiac arrest (OHCA). Methods Patients without evidence of tracheobronchial aspiration on admission bronchoscopy were randomized to prophylactic Amoxicillin–Clavulanic acid 1.2 g every 8 h (P) or clinically-driven antibiotics (C) administered if signs of infection developed during initial 7 days of intensive care unit (ICU) stay. Results Among 83 patients enrolled between September 2013 and February 2015, tracheobronchial aspiration was documented in 23 (28%). Accordingly, 60 patients were randomized. Percentage of patients on antibiotics between days 1–5 was significantly greater in P group. White blood count, C-reactive protein, procalcitonin (PCT) and CD 64 significantly increased during the postresuscitation phase. Except for lower CRP and PCT in group P on day 6 (p Conclusion Bronchoscopy on admission documented tracheobronchial aspiration in 28% of comatose survivors of OHCA. In the absence of aspiration, prophylactic antibiotics did not significantly alter systemic inflammatory response, postresuscitation pneumonia, ICU treatment and outcome (ClinicalTrials.gov Identifier: NCT02899507).
