ABSTRACT
OBJECTIVE: We sought to determine whether the use of currently issued gowns delays initiation of chest compressions and ventilations during cardiopulmonary resuscitation and whether simple gown modifications can reduce this delay. METHODS: Firefighter defibrillation instructors were allocated into pairs and videotaped while performing standardized cardiac arrest scenarios. Three scenarios were compared: "no gown," "standard gown" and "modified gown." Key time intervals were extracted from videotaped data. RESULTS: Ninety-five scenarios were analyzed. Mean time interval to chest compression was 39 seconds (95% confidence interval [CI] 34-43) for "no gown" scenarios, 71 seconds (95% CI 66-77) for "standard gown" scenarios and 59 seconds (95% CI 54-63) for "modified gown" scenarios (p < 0.001). Time to first ventilation was 146 seconds (95% CI 134-158), 238 seconds (95% CI 224-253) and 210 seconds (95% CI 198-223) in the 3 groups, respectively (p < 0.001). Post hoc testing showed that the time differences between all groups were statistically significant. CONCLUSION: Standard gowns protect front-line care providers but cause significant delays to chest compressions and ventilations, potentially increasing patient morbidity and mortality. Minor gown modifications, including pre-tied neck straps and longer waist ties that tie in front, allow for easier use and shorter delays to time-critical interventions. Future research is required to reduce care delays while maintaining adequate protection of emergency medical service providers from infectious disease.
