From 1980 to 1990, operative balloon catheter tamponade was used in 12 patients with cardiac or vascular injuries from penetrating wounds. In nine patients, a balloon catheter was passed into a bleeding site through a bullet track or proximal artery and inflated with saline or radiologic dye. In two of these patients, the proximal balloon catheter was folded on itself, tied in that position, and left in the patient permanently. ⋯ Balloon catheter tamponade was also used on a temporary basis in one patient with a posterior cardiac wound and in one patient with an anterior stab wound of the inferior vena cava at the renal veins, whereas in two patients with high cervical arteriovenous fistulas, one had permanent placement of the balloon catheter while the other had temporary placement. One of the latter patients also had acute hemorrhage. Although all four patients survived, one of the patients with a fistula developed a recurrence and another required two separate operative procedures for correct placement of the balloon to cure the fistula.

Trauma patients in rural areas usually have no access to regional trauma systems or designated trauma centers. Efforts to provide quality trauma care in small hospitals may seriously overextend local capabilities. The urban trauma center retains an important role in trauma care even when the initial care must be provided at the local level. ⋯ Medical records were reviewed to determine the reasons for transfer. Major reasons included the need for further complex surgery, better critical care support, and inadequate blood banks. Trauma centers serving rural areas provide a valuable resource well beyond the initial 24 hours.

Comparative Study
Early detection of myocardial contusion and its complications in patients with blunt trauma.
Myocardial contusion remains an elusive clinical entity, which consumes a disproportionate amount of scarce and expensive critical care resources for the purpose of cardiac monitoring. This study attempts to define a group of patients at high risk who can be identified from the available data present at the time of admission. All patients admitted with the suspicion of a myocardial contusion over a 3-year period were retrospectively studied. ⋯ No predictors of a complication of a myocardial contusion were identified. These data suggest that a combination of easily obtained variables in the emergency department can be used to select a patient population at high risk for myocardial contusion. Prospective evaluation of these variables is necessary.

Diagnostic criteria and guidelines for hospital admission for suspected myocardial contusion (MCC) remain unclear. This study defines and examines the clinical sequelae of patients admitted with a suspicion of MCC. Criteria for observation following isolated, minor blunt chest trauma are suggested. ⋯ There were no complications in patients with isolated chest wall contusions, a normal admission electrocardiogram, and a normal rhythm at 4 hours. There was no significant association between creatine phosphokinase isoenzymes or echocardiogram and cardiac-related complications. The complete absence of significant cardiac sequelae in patients with isolated chest wall contusion, normal admission and 4-hour electrocardiograms, and no other associated major injuries suggests that these patients need not be admitted.

Massive transfusion may cause abnormalities of electrolytes, clotting factors, pH, and temperature and may occur in a scenario of refractory coagulopathy and irreversible shock. Identification of correctable variables to improve survival is complicated by the interplay of this pathophysiology. Temperature may be an under-appreciated problem in the genesis of coagulopathy. ⋯ Severe hypothermia (temperature less than 34 degrees C) occurred in 80% of the nonsurvivors and in 36% of survivors. Patients who were hypothermic and acidotic developed clinically significant bleeding despite adequate blood, plasma, and platelet replacement. Avoidance or correction of hypothermia may be critical in preventing or correcting coagulopathy in the patient receiving massive transfusion.
