ReviewThe impact of emergency medical helicopters on prehospital care.
Emergency medical helicopter services have grown exponentially over the past seventeen years. These services offer rapid transport by flight crews to tertiary care centers with a higher level of medical capabilities. An impact because of helicopters on survival has been well-documented for trauma patients. Assessing usage for other critical care patients remains to be delineated further.

Prehospital advanced trauma life support (ATLS) is controversial because the risks, benefits, and time required to accomplish it remain unknown. We studied 70 consecutive patients with penetrating cardiac injuries to determine the relationships among prehospital procedures, time consumed in the field, and ultimate patient outcome. Thirty-one patients sustained gunshot wounds, and 39 had stab wounds. ⋯ There was no correlation between on-scene time and either the total number of procedures performed (r = .17, P = .17) or IV lines established (r = .06, P = .6). On-scene times did not differ regardless of whether endotracheal intubation or pneumatic antishock garment applications occurred. We conclude that well-trained urban paramedics can perform multiple life-support procedures with very short on-scene times and a high rate of patient survival and that prehospital trauma systems require a minimum obligatory on-scene time to locate patients and prepare them for transport.

Published reports of out-of-hospital cardiac arrest give widely varying results. The variation in survival rates within each type of system is due, in part, to variation in definitions. To determine other reasons for differences in survival rates, we reviewed published studies conducted from 1967 to 1988 on 39 emergency medical services programs from 29 different locations. ⋯ Hypothetical survival curves suggest that the ability to resuscitate is a function of time, type, and sequence of therapy. Survival appears to be highest in double-response systems because CPR is started early. We speculate that early CPR permits definitive procedures, including defibrillation, medications, and intubation, to be more effective.

Paediatric post-injury management: a hospital-based review of deaths.
In order to begin to evaluate the need for an integrated trauma management service for injured children, a retrospective review of deaths following admission to a suburban teaching hospital was conducted. The medical records and coroners' reports for 64 consecutive cases over 68 months were reviewed, looking for errors in care which may have contributed to fatal outcomes. There was a male predominance (64%). ⋯ This can be explained partly by the predominance of what were judged to be irretrievable intracranial injuries (90%) in patients suffering blunt injuries. In contrast, an analysis of the same patient group revealed that in 30-50% the fatality could have been prevented by the full application of well recognized safety strategies. While strategies such as triage and trauma teams should reduce the error rate, it is yet to be proven that optimal post-injury care will significantly reduce mortality.

A Pediatric Trauma Score (PTS) was recently developed and is rapidly gaining acceptance as a triage tool. This study examines the utility of the PTS as compared with the Revised Trauma Score, which is applicable to all ages. The charts of 376 children 0 to 14 years of age who were admitted to the trauma service of a level 1 trauma center were reviewed. ⋯ Triage accuracy was 68.3% for the PTS and 78.8% for the Revised Trauma Score. The Revised Trauma Score is easy to use and universal in its applicability. The PTS involves learning a separate scoring system and is of no advantage.
