We examined the recent experience of a large urban trauma center to identify overall morbidity and factors predictive of outcome in patients undergoing colostomy closure after trauma. ⋯ Colostomy closure after trauma remains associated with significant morbidity. The patients in whom a colon injury was the indication for initial colostomy experienced high morbidity (55%) after subsequent closure. Patients who had a colostomy for rectal injury had a low morbidity after closure (6.25%). Intraoperative difficulties (longer operative times, higher blood loss) and long delays until colostomy closure increase complication rates. Timely closure may improve outcome after operation for bowel continuity restoration. Morbidity associated with colostomy closure should be considered additional evidence for performing primary repair of colonic injuries. Because the morbidity of colostomy closure after rectal injuries is low, proximal colostomy for extraperitoneal rectal injuries should remain the treatment of choice.

As part of an ongoing prospective evaluation of the response of acute respiratory failure (ARF) to ventilation with titrated amounts of positive end-expiratory pressure (PEEP), a subset of patients with a poor response to the initial application of PEEP and radiographic evidence of pleural effusion was identified. The effusion(s) were treated by tube thoracostomy (TT) to test the hypothesis that drainage would have a favorable effect on oxygenation and compliance in critically ill patients with substantial pulmonary dysfunction. ⋯ Drainage of pleural fluid resulted in a significant improvement in oxygenation in ARF patients with pleural effusions who were refractory to treatment with mechanical ventilation and PEEP. TT represents a simple and safe alternative for aggressive management of selected patients, obviating the inherent risk of pneumothorax with thoracentesis and possibly avoiding the need for more complex forms of support in this critically ill patient population.

Implanted insulin pumps (IIPs) are an alternative treatment for diabetes mellitus. To maintain good glycemic control, patients with an IIP require frequent surgical interventions. ⋯ Long-term use of IIPs results in significant improvements in clinical parameters and quality of life for individuals with insulin-dependent diabetes mellitus. Relatively frequent operations are required for maintaining pump function, which are done with a local anesthetic with minimal morbidity.

Randomized Controlled Trial Clinical Trial
Use of the rapid/shallow breathing index as an indicator of patient work of breathing during pressure support ventilation.
Measuring patient work of breathing (WOBpt) has been suggested to provide safe, aggressive weaning from mechanical ventilation. We compared WOBpt and pressure-time-product (PTP) to routine weaning parameters [breath rate (f), tidal volume (VT), frequency/tidal volume ratio (f/VT)] at different levels of pressure support ventilation (PSV). ⋯ Direct measurement of WOBpt is invasive, expensive, and' may be confusing to clinicians. Monitoring f/VT may be useful when changing PSV during weaning.

Comparative Study
Management of blunt splenic trauma: significant differences between adults and children.
Although highly successful in children, nonoperative management of blunt splenic injury in adults is less defined. The purpose of this study was to determine whether mechanism of injury, grade of splenic injury, associated injuries, and pattern of injury differ between adults and children (younger than 15 years of age). ⋯ Rather than children simply being physically different, they are injured differently than adults, hence the high rate of nonoperative management.
