The purpose of this study was to determine the impact of field orotracheal intubation (OI) by urban emergency medical technician-paramedics (EMT-Ps) on outcome compared with trauma score and injury severity score (TRISS) expectations. The records of all trauma patients intubated by EMT-Ps or hospital personnel were abstracted for OI attempts/ successes, use of neuromuscular blockade (NMB), scene time, discharge neurological status, and hospital survival compared with TRISS. EMT-Ps attempted 43% of all incubations; 81% were successful versus 98% by hospital staff (P< .05). NMB was used by 76% of hospital incubations versus none by EMS (P < .05). Scene time was 10.3 ± 3.2 minutes versus 11.6 ± 2.1 for patients intubated by emergency medical services (EMS) and hospital staff (P< .05). Sixty percent of patients intubated by EMS versus 68% by hospital staff had good/moderate discharge neurological status. Survival for patients intubated by EMS versus hospital staff was 11% and 40%, respectively, compared with 2% and 45% expected by TRISS. Field OI by urban EMT-Ps has a favorable impact on survival with good neurological outcome (P < .05).
