Comparative Study Clinical Trial Controlled Clinical Trial
Comparison of volume control and pressure control ventilation: is flow waveform the difference?
To examine the hypothesis that a decelerating inspiratory flow waveform is responsible for improvements in gas exchange during pressure control ventilation for acute lung injury. ⋯ Both pressure control ventilation and volume control ventilation with a decelerating flow waveform provided better oxygenation at a lower peak inspiratory pressure and higher mean airway pressure compared to volume control ventilation with a square flow waveform. The results of our study suggest that the reported advantages of pressure control ventilation over volume control ventilation with a square flow waveform can be accomplished with volume control ventilation with a decelerating flow waveform.

To examine hospital, trauma system, and reimbursement factors that offset the financial burdens of trauma care delivery and to assess how proposed Medicaid and Medicare budget cuts may affect the ability of hospitals to alleviate financial pressures related to trauma care delivery. ⋯ Proposed Medicaid and Medicare payment cuts are likely to eliminate the delicate financial balance that many urban hospitals have achieved in providing trauma care. The erosion in funding from public programs may portend a new wave of trauma center closures as hospitals seek to deal with reduced reimbursement by eliminating unprofitable services.

The purpose of this study was to compare the outcomes of trauma patients with an Injury Severity Score (ISS) > 12 who had the trauma team involved (TTA) in their resuscitative care to those that did not (TTNA). ⋯ In a Level I trauma center, the outcomes of trauma patients with an ISS > 12 are statistically significantly better if the trauma team is activated than if the patients are managed on an individual service-by-service basis.

To review the results of surgical management of heterotopic ossification about the elbow in burned patients. ⋯ Surgery for both limited range of motion as well as ulnar nerve compression is effective in cases of heterotopic ossification about the elbows of burned patients. Early operative intervention is indicated in progressive disease, particularly ulnar nerve palsy, if soft-tissue quality is adequate. Complications with 25% of elbows suggest that use of olecranon osteotomy for joint access may warrant review.

Nonoperative management of hemodynamically stable blunt hepatic injury has emerged as an acceptable and safe treatment. Surveillance of this population's injuries is costly. As a prelude to establishing practice guidelines, the utility of repeat computed tomographic (CT) scans was investigated. ⋯ No patients failed nonoperative treatment or succumbed to their injuries. Findings on repeat CT scan have not altered the decision to discharge the clinically stable patient having suffered a grade III or lower liver injury.
