Pulmonary contusions and critical care management in thoracic trauma.

Many victims of thoracic trauma require ICU care and mechanical ventilatory support. Pressure and volume-limited modes assist in the prevention of ventilator-associated lung injury. Ventilator-associated pneumonia is a significant cause of posttraumatic morbidity and mortality. Minimizing ventilator days, secretion control, early nutritional support, and patient positioning are methods to reduce the risk of pneumonia.

Feasibility, reliability and validity of an operative performance rating system for evaluating surgery residents.

BACKGROUND: Resident evaluation traditionally involves global assessments including clinical performance, professional behavior, technical skill, and number of procedures performed. These evaluations lack objective assessment of operative skills. We describe an operative performance rating system (OPRS) designed to provide objective operative performance ratings using a sentinel procedure format. METHODS: Ten-item procedure-specific rating instruments were developed. Items included technical skills, operative decision making, and general items. A 1 to 5 (5 = excellent) scale was used for evaluation. Six procedures had sufficient forms returned to allow evaluation. Inter-rater reliability was determined by having faculty evaluators view 2 videotaped operations. RESULTS: Return rates for the Internet-based form were full-time faculty (92%), volunteer faculty (27%), and overall (67%). Reliability, (average interitem correlation), and total procedures evaluated were excisional biopsy, 0.90, (0.48), 77; open inguinal herniorraphy, 0.94, (0.62), 51; laparoscopic cholecystectomy, 0.95, (0.64), 75; small-bowel and colon resection, 0.92, (0.58), 30; parathyroidectomy, 0.70, (0.19), 30; and lumpectomy, 0.92, (0.51), 38. Years of training accounted for 25% to 57% of the variation in scores. Inter-rater variability was observed; however, the average rater agreement was reliable. CONCLUSIONS: Internet-based management made obtaining the data feasible. The OPRS complements traditional evaluations by providing objective assessment of operative decision-making and technical skills. Interitem correlations indicate the average rating of items provides a reliable indicator of resident performance. The OPRS is useful in tracking resident development throughout postgraduate training and offers a structured means of certifying operative skills.

Superior vena cava perforation and cardiac tamponade after filter placement in the superior vena cava--a case report.

The purpose of this paper is to report the complication of perforation of the superior vena cava (SVC) leading to cardiac tamponade after the insertion of a Trapease IVC filter in the SVC position. A 29-year-old man was hit by motor vehicle and sustained numerous injuries including a left skull fracture, intracerebral hemorrhage, and left open tibial shaft fracture. During his hospitalization, he developed an extensive symptomatic right upper extremity deep venous thrombosis involving the brachial, axillary, subclavian, internal jugular, and brachiocephalic veins. Owing to an intracerebral bleed, anticoagulation was contraindicated. Therefore, a Trapease filter (Cordis Inc.) was placed in the SVC via the left subclavian vein. Four hours later, the patient became hypotensive with associated tachycardia and tachypnea. Computed tomography of his chest revealed a hematoma around the SVC, a moderate amount of fluid within the pericardium, and a moderate-sized right pleural effusion. The patient was taken to the operating room and a pericardial window was performed. Approximately 500 cc of blood was evacuated from the pericardium and immediate improvement in vital signs was noted. The patient was discharged from the hospital 2 weeks later and at 6-month follow-up had made full recovery. This is the first case of SVC perforation leading to cardiac tamponade after the insertion of a Trapease filter. Owing to the rigid structure of the filter and associated motion of the SVC and pericardium, the Trapease filter may be contraindicated in the SVC.
