| Popis: | Rural trauma victims often require prolonged transport by s with limited scopes of practice. We evaluated the impact of telemedicine (TM) to a moving ambulance on outcomes in simulated trauma patients.This is an institutional review board approved, prospective double-blind study. Three trauma scenarios (blunt torso trauma, epigastric stab wound, and closed head injury) were created for a human patient simulator. Intermediate emergency medical technicians (EMTs; n = 20) managed the human patient simulator, in a moving ambulance. In the TM group, physicians (n = 12) provided consultation. In the non-TM group, EMTs communicated with medical control by radio, as necessary. We tabulated the fraction of 13 key signs, 5 pathologic processes, and 12 key interventions that were performed. Vital signs and Sao2 (%) were recorded. Data were compared using the Wilcoxon rank-sum test.Lowest Sao2 (84 ± 0.7 vs. 78 ± 0), lowest systolic blood pressure (70 ± 1 vs. 53 ± 1), and highest heart rate (144 ± 0.9 vs. 159 ± 0.5) were significantly improved in the TM group (p0.001). Recognition rates for key signs (0.96 ± 0.01 vs. 0.79 ± 0.05), processes (0.98 ± 0.02 vs. 0.75 ± 0.05), and critical interventions (0.92 ± 0.02 vs. 0.49 ± 0.03) were higher in the TM group (p0.003). EMTs were successfully guided through needle decompression procedures in 22 of 24 cases (zero in the non-TM group).TM to a moving ambulance improved the care of simulated trauma patients. Furthermore, procedurally naïve EMTs were able to perform needle thoracostomy and pericardiocentesis with TM guidance. |
