Recent advances in the resuscitation and stabilization skills of prehospital emergency care providers have done much to improve the quality of immediate care provided to suddenly ill or injured patients. Although much of the innovation and leadership in this area has been provided by emergency department physicians, most of them still lack an adequate appreciation of the circumstances under which these skills are executed. While many physicians participate in prehospital care teaching and evaluation of the system, most have not gained personal experience in those aspects of care foreign to hospital environment. They are particularly unacquainted with the intricacies of rescuing patients from automobile accidents and similar entrapments. It is not unusual, however, for an accident victim to spend half of the time required for the prehospital phase of emergency medical care undergoing extrication, and in many cases this must be done before full advanced life support measures may be initiated.
