Comparative Study
Prospective comparison of clinical judgment and APACHE II score in predicting the outcome in critically ill surgical patients.
Prospective identification of patients who will not survive has been proposed as a means of limiting utilization of medical resources including critical care. This study prospectively compared prediction of outcome for surgical ICU patients by clinical assessment and the APACHE II score. Five hundred seventy-eight patients were assessed within 24 hours of admission by the ICU attending physician and predicted to live or die. ⋯ Over 40% of patients predicted to die by both methods actually survived. This study demonstrates that clinical assessment is superior to APACHE II in predicting outcome in this group of surgical patients, although the difference is small. In addition, this study suggests that neither clinical assessment nor the APACHE II score, when obtained within 24 hours of admission, is very reliable at predicting which surgical ICU patients will die.

Emergency thoracotomy is a standard procedure in the management of cardiac arrest in patients sustaining severe trauma. We examined the records of 463 moribund trauma patients treated at our institution from 1980 to 1990 to refine indications for emergency thoracotomy. Patients underwent thoracotomy either in the emergency department (ED) (n = 424) or in the operating room (OR) (n = 39) as a component of continuing resuscitation after hospital arrival. ⋯ Patients with penetrating trauma and in profound shock (BP less than 60 mm Hg) or mild shock (BP 60-90 mm Hg) with subsequent cardiac arrest had survival rates of 64% (27 of 42) and 56% (30 of 54), respectively. None of the patients with absent signs of life, defined as full cardiopulmonary arrest with absent reflexes (n = 215), on initial assessment by paramedics in the field, survived. We conclude that (1) no emergency thoracotomy should be performed if no signs of life are present on the initial prehospital field assessment; (2) emergency thoracotomy is an indicated procedure in most patients sustaining penetrating trauma; (3) blunt traumatic cardiac arrest is a relative contraindication to emergency thoracotomy.

Emergency center thoracotomy was performed at our facility on 389 patients from 1984 through 1989. There were no patients excluded from the study, and survival for all patients was 8.3% with survival rates of 15.2% and 7.3% for stab and gunshot wounds, respectively. Emergency center thoracotomy was performed on 42 patients suffering from isolated extrathoracic injuries with 7% survival. ⋯ Of the survivors, prehospital endotracheal intubation prolonged successful toleration of CPR to 9.4 minutes compared with 4.2 minutes for nonintubated surviving patients (p less than 0.001). Emergency center thoracotomy is useful in the resuscitation of victims dying of penetrating truncal trauma. Prehospital endotracheal intubation significantly lengthened the time of successful CPR.

Comparative Study
Vascular injuries in a rural state: a review of 978 patients from a state trauma registry.
The demographics, etiology, and outcome of 1148 vascular injuries suffered by 978 patients reported from eight trauma centers in a largely rural state to a trauma registry (NCTR) data base containing 26,617 patients entered over a 39-month time interval were analyzed. Vascular injury patients were more frequently transferred by helicopter (18%), referred from other hospitals (45%), transfused more blood (8 units mean/24 hours), had higher mean ISS values (14 vs. 9), had lower systolic blood pressures on admission (113 vs. 128 mm Hg), had higher emergency department mortality (3.3%), and required immediate surgery more often (79%) when compared with nonvascular injury NCTR patients (p = 0.0001). Vascular injury patients had significantly longer hospital stays (13 vs. 10 days), longer ICU stays (5 vs. 4 days), and greater hospital costs ($22,500 vs. $12,300) while incurring more serious AIS values for the regions of the chest, abdomen, and extremities. ⋯ Forty-seven percent of vascular injuries were extremity lesions; the amputation rate was 1.3%; and management was most often by simple repair (41.9%) or patching (22.2%). Rural vascular injury patients had a high incidence of blunt trauma (43.4%) and were older (average, 51 years); they were transported by helicopter more often (30.3%) and were frequently referred from another hospital (77.8%); they had longer ICU, ventilator, and hospital stays and greater hospital charges; and they had higher mortality (14.2%) compared with urban vascular trauma victims. The data suggest a need for the trauma care system to focus on earlier recognition, stabilization, and rapid transportation of this most seriously injured group of patients.

Large urban trauma centers care for injured children as well as adults in many areas of the country, but the quality of care in these hospitals has not been evaluated versus that available at pediatric trauma centers. The recent validation of TRISS methodology in pediatric populations allowed us to evaluate the quality of pediatric trauma care being provided in a level I trauma center treating injured patients of all ages. We reviewed the records of 353 injured children (aged 0-17 years) who were admitted to our trauma center over a 30-month period for the following data: demographics, mechanism of injury, initial physiologic status (RTS), surgical procedures required, need for intensive care, nature and severity of the injuries (ISS), and outcome. ⋯ The Z scores ranged from +0.32 for the children aged less than 2 years to +3.98 for the older age group (14-17 years). We conclude that the quality of care for pediatric trauma patients admitted to trauma centers that care for patients of all ages compares favorably with national standards. In most areas of the country, improvements in pediatric trauma care will likely come from addressing the special needs of injured children in general trauma centers rather than from developing separate pediatric facilities.
