Randomized Controlled Trial Comparative Study Clinical Trial
Prospective evaluation of epidural and intravenous administration of fentanyl for pain control and restoration of ventilatory function following multiple rib fractures.
To evaluate the efficacy of opiate administration regimens, 32 patients with multiple rib fractures were prospectively randomized to receive either continuous epidural (ED) or continuous intravenous (IV) infusions of fentanyl. Dosage was titrated to individual subjective pain relief. Ventilatory function tests (VFTs), arterial blood gases (ABGs), and visual analog scores were obtained before and after the institution of analgesia. ⋯ Side effects were similar between the groups, with pruritus being more pronounced with ED fentanyl administration. The data demonstrate that the continuous ED fentanyl method offers excellent relief of pain and improvement in ventilatory function and has distinct advantages over IV fentanyl administration with respect to changes in ABGs and MIP. The continuous infusion of epidural opiates should be the preferred analgesic method for patients at high risk of developing pulmonary complications following multiple rib fractures.

Comparative Study
Comparison of the ability of adult and pediatric trauma scores to predict pediatric outcome following major trauma.
The Pediatric Trauma Score (PTS) has been identified as the only accurate and adequate means of predicting outcome in pediatric trauma. In answer to the increasing number of trauma patients arriving at local hospitals, the ability of the adult Trauma Score (TS) to predict pediatric trauma outcome was tested. Of the total 2,604 pediatric trauma cases in the North Carolina State Trauma Registry, 441 had both a PTS and TS available for analysis. ⋯ Stepwise discriminant analysis demonstrated that TS was the stronger predictor of outcome and the PTS added only 9% (partial R2 = 0.09) more accuracy to TS for emergency department disposition and only 6% (partial R2 = 0.06) for hospital disposition. The results of this research demonstrate that TS is a useful method of predicting outcome in pediatric trauma. The use of both scores for each patient does not increase the predictive value of the scores.

The value of the TRISS method for interhospital comparisons of trauma care was studied using data for 5,616 consecutive patients from three trauma centers and five community hospitals. Z-scores were used to compare mortality rates. ⋯ Remedies to the first two of these limitations can be addressed within the present TRISS method. A remedy for the third requires a new method.

Trauma room lateral cervical spine radiographs (LCSR) may improve the safety of intubation and transportation of multiply injured patients by providing earlier recognition of spinal vertebral injuries. We prospectively evaluated 60 consecutive trauma admissions to determine the impact of clearance of cervical spine radiographs on patient care. Fifty-three patients had no cervical spine injury (CSI). ⋯ LCSR failed to identify three of the seven acute CSI (all three had C7 fractures). The spine-injured were managed with cervical collars and no new neurologic injury developed. We conclude that: 1) LCSRs do not appear to alter urgent management of multiply injured patients during resuscitation and transportation; 2) chest radiographs and emergency investigations should not be delayed by repeated LCSR in the trauma room as it may be difficult to fully exclude CSI in many trauma patients; 3) we support the current ATLS guidelines, which suggest that all patients should be presumed to have an unstable CSI until the presence of cervical injury has been excluded.

We studied the effect of deferoxamine (DFO) infused after burns on hemodynamic stability as well as local and systemic inflammation and oxidant-induced lipid peroxidation. Eighteen anesthetized sheep were given a 40% of total body surface burn and fluid resuscitated to restore oxygen delivery (DO2) and filling pressures to baseline values. Animals were resuscitated with lactated Ringer's (LR) alone or LR plus 1,500 ml of a 5% hetastarch complexed with DFO (8 mg/ml). ⋯ Burn tissue edema, measured as protein-rich lymph flow, was significantly increased with the administration of DFO compared with the other groups. We conclude that DFO used for burn resuscitation prevents systemic lipid peroxidation and decreases the vascular leak in nonburn tissues while also increasing O2 utilization. Resuscitation with hetastarch-DFO may accentuate burn tissue edema, possibly by increased perfusion of burn tissue.
