Deaths from motor vehicle crashes: patterns of injury in restrained and unrestrained victims.

A time comparison study of motor vehicle crashes in Monroe County, New York, from 1983 to 1986 was completed. Using a database of police accident reports, hospital logs, and autopsy reports from the county coroner, the hospital and autopsy reports of 91 unrestrained and 27 restrained fatally injured victims were reviewed. The hypothesis was that safety belts do not change patterns of injury in fatally injured victims. Patient data, seating position, and direction of impact were the same for both groups, while ejections occurred only in the unrestrained group (19.8%). Injury Severity Score (ISS), major injuries in AIS-85 categories for the Head, Thorax, Abdomen, and in AIS-85 Code 5 or 6 categories for the Head, Thorax, Abdomen were the same in unrestrained and restrained victims, except for the greater incidence of cerebral contusions in the unrestrained group (71% vs. 37%, p = 0.002). Cranial injuries were the most likely cause of death in nearly two thirds of the victims in both groups. The incidence of major head (other than cerebral contusion), thoracic, and abdominal injuries in unrestrained and restrained fatally injured victims was the same. This suggests that severe collisions with crushing, intrusion, or significant deceleration exceed the ability of restraints to prevent many fatal injuries.

Radical nephrectomy in patients with renal cell carcinoma with venous, vena caval, and atrial extension.

BACKGROUND: From July 31, 1968, through August 31, 1992, 100 patients with renal cell carcinoma extending into the renal vein, vena cava, and right atrium were treated and evaluated at our institution. Each patient underwent radical nephrectomy with vena cavotomy and atriotomy as considered to be appropriate for each individual patient's tumor thrombus. METHODS: The charts were retrospectively analyzed, and surveys were sent to survivors or nearest of kin. RESULTS: The median age was 61 years, and two thirds of the tumors occurred in men (67 cases). Of the 100 patients with renal cell carcinoma resected, 13 patients (13%) had atrial extension; 75 patients (75%) had vena caval extension; and 12 patients (12%) had extension only into the renal vein. Seventy-two patients (72%) had no evidence of metastatic disease at the time of surgery and have a median survival of 21.1 years. Five-year survival is 64%, and 10-year survival is 57%. Twenty-eight patients (28%) had evidence of metastatic intraoperative and/or pathologically proven metastatic disease and have a median survival of 2.5 years with a 5-year survival of 20% and no patient living beyond 7.8 years. CONCLUSION: We believe that an extended operation for renal cell cancer with involvement of the renal vein, vena cava, and right atrium is warranted in properly selected patients and ensures reasonable long-term survival.

A rational screening and treatment strategy based on the electrocardiogram alone for suspected cardiac contusion.

The charts of 71 patients admitted to one teaching institution over a 4-year period with a primary or secondary diagnosis of "rule out cardiac contusion" and of another 62 admitted to a second institution with more severe injuries and suspicion of cardiac contusion were reviewed to determine if mortality or morbidity would have occurred if all patients with normal electrocardiograms (EKGs) in the emergency department (ED) were discharged (or admitted to unmonitored beds for other injuries). Only 13 patients developed cardiac problems: two elderly patients died in the ED, while the others experienced arrhythmias or, less commonly, pump failure requiring treatment or observation. All 13 had EKG changes present while still undergoing evaluation in the ED: 11 had a specific problem on arrival, 1 developed a problem while still being evaluated in the ED, and the 13th had what was probably an iatrogenic problem. Importantly, 5 of 12 patients had normal creatine phosphokinase-MB fractions, and 5 of 9 had normal echocardiograms. No patient with a normal EKG had subsequent cardiac problems. Operative intervention for other injuries was necessary in 26 patients overall, and there was no cardiac morbidity. We conclude that had the EKG been used as the sole screening tool, approximately 25% of these patients could have been discharged from the ED without missing problems. In addition, management would have been greatly simplified, and the hospital would have realized substantial savings, both in terms of direct costs and in the freeing of valuable and scarce resources.
