Open lung biopsy has proven beneficial in the treatment of life-threatening pulmonary diseases. Its safety and efficacy in infants and children placed on extracorporeal membrane oxygenation (ECMO) for severe respiratory failure is not known. The authors reviewed eight cases (4 neonates, 3 infants, 1 child) who underwent open lung biopsy while on ECMO. ⋯ Open lung biopsy is well tolerated during ECMO. It accurately determines pulmonary pathology and provides valuable prognostic information. Earlier biopsy for patients whose diagnoses are uncertain or who are not responding to ECMO may improve the mortality rate for this high-risk group.

There have been few documented cases of sand aspiration. The authors report on a 3-year-old boy who suffered severe respiratory compromise secondary to sand aspiration. Emergency intubation and subsequent bronchoscopy were required to relieve airway obstruction. The patient did well and suffered no long-term sequelae.

Venovenous extracorporeal membrane oxygenation: the effects of proximal internal jugular cannulation.
Venovenous (VV) extracorporeal membrane oxygenation (ECMO) using a double lumen catheter has become an accepted method of providing ECMO support for critically ill newborn infants. In addition, use of the cephalic jugular catheter can provide augmented venous blood flow, potentially prevent increased cerebral venous pressure, maintain cerebral venous blood flow, and increase ECMO oxygen delivery. The authors compared their experience using VV double-lumen (VVDL) ECMO with a cephalic jugular catheter with their previous experience using venoarterial (VA) ECMO. ⋯ No other significant differences were noted for any of the calculated oxygen transport variables comparing VVDL with VA ECMO infants with CDH treated with VVDL ECMO were extubated sooner than those treated with VA ECMO (10.3 days VVDL v 15.4 days VA; P = 048). In addition, there was no significant difference in the overall incidence of complications or death. This experience suggests that VVDL ECMO using a cephalic jugular catheter results in shorter ECMO runs and provides support that is comparable to VA ECMO for infants with CDH and MAS while avoiding carotid artery cannulation and ligation.

To determine whether hemodynamically significant bleeding occurs after pediatric femur fractures. ⋯ Hemodynamic instability or evidence of a declining hematocrit in the child should not be attributed to a closed femur fracture and that other sources of blood loss must be found.

Despite recent advances in surgical technique, posthysterotomy preterm labor remains a major determinant of postoperative fetal morbidity and mortality after in utero repair of congenital diaphragmatic hernia (CDH). Temporary fetal tracheal occlusion, or "PLUG" (Plug the Lung Until it Grows), reverses the pulmonary hypoplasia seen in experimental models of CDH and provides an alternative treatment strategy for some fetuses with CDH. Adaptation of current, minimally invasive surgical technology to the PLUG technique allows treatment of CDH without opening the uterus. ⋯ Once the foam was in its final endotracheal position, dissolution of the gelatin membrane allowed expansion of the foam to produce a water impervious tracheal occlusion. This two-trocar video-fetoscopic PLUG technique was performed successfully in all four fetuses, with a sequential decrease in operating time (median, 3.5 hours). Although two fetuses aborted postoperatively, the other two were carried successfully to term and demonstrated the anticipated physiological effects of adequate tracheal occlusion at the time of delivery.
