Comparative Study
Prehospital Index: a scoring system for field triage of trauma victims.
The Prehospital Index (PHI) is a triage-oriented trauma severity scoring system comprising four components: systolic blood pressure, pulse, respiratory status, and level of consciousness, each scored 0 to 5. The PHI was developed after analysis of 313 cases to provide an objective prehospital scoring system for distinguishing less seriously injured patients (minor trauma) from those patients who are likely to die within 72 hours after injury or who require general or neurosurgical operative intervention within 24 hours (major trauma). A PHI of 0 to 3 indicated minor trauma, and a PHI of 4 to 20 signified major trauma. ⋯ Of the 351 patients scored as minor trauma in the field, there was a 0% mortality and only a 0.3% operative rate. Those scored as major trauma in the field had a mortality of 27% (PHI 4 to 7, 0%; PHI 8 to 20, 53%) and an operative rate of 40.5% (PHI 4 to 7, 22%; PHI 8 to 20, 57.9%). These data demonstrate the ability of the PHI to predict mortality (P less than .001) and the need for emergency general or neurosurgical operative intervention (P less than .001).(ABSTRACT TRUNCATED AT 250 WORDS)

Mass casualty incidents provide valuable lessons for the prehospital provider. A re-evaluation of large-scale rescue operations which require a complex network of agencies, communications, and on-scene triaging frequently exposes common weaknesses and errors. This article identifies these common errors and provides guidelines for more effective mass casualty management.

Effectiveness of a protocol for intravenous (IV) access during pediatric resuscitation was prospectively evaluated to determine whether utilization of a specified sequence of measures would reduce IV access time compared with resuscitations deviating from the protocol. The protocol involved rapid sequential attempts at percutaneous femoral vein catheterization, saphenous vein cutdown, and intraosseous infusions if initial percutaneous peripheral IV insertion failed. ⋯ Even with incomplete compliance, 66% of resuscitations achieved IV access within the first five minutes. Our experience indicates that IV access during pediatric resuscitation should rarely be delayed beyond the fifth minute if all available IV techniques are used.
