Comparative Study
Venovenous versus venoarterial extracorporeal membrane oxygenation in congenital diaphragmatic hernia.
Extracorporeal membrane oxygenation (ECMO) has a significant role as a final rescue modality in severe respiratory failure of the newborn with congenital diaphragmatic hernia (CDH). The objective of this study was to compare the efficiency of venovenous (VV) versus venoarterial (VA) ECMO in newborns with CDH. ⋯ The authors conclude that VV ECMO is as reliable as VA ECMO in newborns with CDH in severe respiratory failure who need ECMO support and who can accommodate the VV double-lumen catheter. Because of its potential advantages, VV ECMO may be the preferred ECMO method in these infants.

The aim of this study was to determine in a pediatric population whether a routine chest x-ray after central venous access is necessary when the central venous catheter is placed with intraoperative fluoroscopy. ⋯ The number of complications encountered in children who had central venous access of the subclavian vein or internal jugular central vein with intraoperative fluoroscopy was infrequent, the number of misplaced catheters was minimized with intraoperative fluoroscopy, and all children with pulmonary complications showed clinical signs suggestive of pulmonary complications before postoperative chest x-ray. Therefore, children who have had central venous access of the subclavian and internal jugular vein with intraoperative fluoroscopy do not appear to require a routine chest x-ray after catheter placement unless clinical suspicion of a complication exists.

Rhabdomyosarcoma is the most common type of soft tissue sarcoma in children. The tumor spreads by local extension, to regional lymph nodes, or by distant metastases. Metastatic spread to the testicle has been rarely described. ⋯ A second boy 17 years of age had a primary tumor involving the left upper extremity treated with amputation, chemotherapy, and radiotherapy. A relapse was noted 2 years later in the left testicle and was treated with orchiectomy. The authors discuss the implications and the management of this rare presentation of metastatic rhabdomyosarcoma.

The aim of this study was to describe the state of pediatric trauma system development in the United States in 1997 and 1998 and to characterize the hospitalization patterns of injured children in states with different types of pediatric trauma systems. The authors also investigated the impact of sociodemographic, injury, and geographic characteristics on those hospitalization patterns. ⋯ Even in states with trauma systems, a large proportion of severely injured children are treated in nontrauma center facilities.

Preliminary studies have shown aminocaproic acid (AMICAR), an inhibitor of fibrinolysis, reduced the incidence of intracranial hemorrhage and significant surgical site bleeding in patients on extracorporeal membrane oxygenation (ECMO). The purpose of this analysis is to determine if these benefits remain when AMICAR is used in a large population. ⋯ In this large experience, use of AMICAR for high-risk patients on ECMO did not appear to alter the rate of neonatal intracranial hemorrhage, but did significantly reduce the incidence of surgical site bleeding. AMICAR remains a valuable tool for the prevention of hemorrhage in patients undergoing operation prior to or while on ECMO.
