Three of 87 children with blunt liver injuries initially managed without operation required late intervention for bile leakage. Abdominal computed tomography scans in these patients showed liver injuries extending into the porta hepatis. Clinical courses were characterized by persistent abdominal pain, low-grade fever, and prolonged ileus. ⋯ Radionucleide scan and endoscopic retrograde cholangiopancreatography are reliable modes of diagnosis and localization. Transampullary biliary decompression is a newer, effective modality for management of the proximal and/or partial bile duct injuries. Treatment must be individualized according to the site and extent of injury.

Pulmonary sequestration is a mass of abnormal pulmonary tissue that does not communicate with the tracheobronchial tree and is supplied by an anomalous systemic artery. Whereas extralobar sequestration is clearly congenital, intralobar sequestration, which frequently presents in older children with pathological findings showing acute and chronic inflammation, may have an acquired origin secondary to frequent infections. Several large autopsy series support an acquired etiology of intralobar sequestration. ⋯ Case 4 presented as a 6 year old. The operative specimen showed extensive bronchiectatic changes with marked acute and chronic inflammation. These cases support the congenital origin of intralobar sequestration and suggest a temporal progression from no inflammation to severe acute and chronic inflammation.

It is generally recommended that patients with sickle cell disease receive red blood cell (RBC) transfusions before undergoing general anesthesia and surgery. Since RBC transfusions are costly, inconvenient, and may cause serious complications, it might be useful to identify groups of patients for whom they are not absolutely necessary. We report our experience with 54 pediatric patients undergoing 66 elective surgical procedures without preoperative transfusion preparation. ⋯ Pulmonary complications were especially more prevalent in the group undergoing thoracotomy, laparatomy, or T&A (9/29 v 0/37 for all other procedures, P < .001). We conclude that preoperative transfusions might be avoided in children with sickle cell disease who undergo most minor surgical procedures on an elective basis. Patients undergoing thoracotomy, laparotomy, or T&A are at a relatively higher risk of developing postoperative complications and would comprise ideal groups for evaluation of preoperative transfusion regimens in prospective carefully controlled, randomized studies.

Extracorporeal membrane oxygenation in the management of cardiac failure secondary to myocarditis.
While most patients with viral myocarditis have a relatively uncomplicated clinical course, a small number of patients will present with cardiogenic shock unresponsive to standard medical therapy. We describe the clinical course of three patients who developed profound cardiac failure secondary to a documented viral myocarditis. Each patient was managed using venoarterial (VA) extracorporeal membrane oxygenation (ECMO) support using the right common carotid artery/internal jugular vein for cannulation. ⋯ One patient developed global myocardial necrosis and ultimately died. This small series demonstrates a role for ECMO in the management of cardiac failure due to acute viral myocarditis unresponsive to medical therapy. Our experience also suggests that balloon atrial septostomy may be useful to decompress the left atrium and ventricle of patients with acute myocarditis while on ECMO.

Data from the Extracorporeal Life Support Organization (ELSO) regarding the use of extracorporeal membrane oxygenation (ECMO) in pediatric patients with respiratory failure are reviewed. Two hundred eighty-five children between the ages of 14 days and 18 years were supported with ECMO between January 1982 and September 1991. Although these data represent the experience of 52 ECMO centers, seven centers accounted for over 50% of the total. ⋯ The duration of ECMO was 4 hours to 35.5 days with a mean of 245 +/- 165 hours, which is approximately 10 days. Duration for survivors was 222 +/- 151 hours compared with 266 +/- 176 hours for nonsurvivors. ECMO complications are divided into two categories: mechanical (directly related to the ECMO circuit) and medical (patient related).(ABSTRACT TRUNCATED AT 250 WORDS)
