We reviewed a single institution experience with extracorporeal membrane oxygenation (ECMO) in the perioperative management of cardiac transplantation. ⋯ ECMO can bridge children to cardiac transplantation. Survival is significantly impaired in bridge-to-transplant candidates stratified by pre-ECMO cardiac arrest. ECMO can also help transition from cardiopulmonary bypass after transplantation and provide effective support during acute rejection.

Pediatric major resuscitation--respiratory compromise as a criterion for mandatory surgeon presence.
The American College of Surgeons Committee on Trauma has indicated that there are minimum criteria for a trauma surgeon to respond to a major resuscitation (MR) within 15 minutes. These criteria have been required for children without significant data to support their validity. Our hypothesis is that prehospital intubation/respiratory compromise (IRC) as a criterion to define an MR will be an accurate predictor. ⋯ Injured children with prehospital IRC are significantly more likely to die, have a higher ISS, and a longer ICU length of stay. Prehospital respiratory distress in injured children in our trauma system is a reasonable criterion to define an MR in children.

As a first step toward the development of an artificial placenta, we investigated the relationship between blood flow rate through an arteriovenous (A-V) circuit/oxygenator and both CO2 elimination and hemodynamic stability in a small animal model. ⋯ In this rabbit model, A-V blood flows at 25% to 30% of cardiac output allow full gas exchange without hemodynamic compromise. This model raises the possibility of using A-V support and an artificial placenta in newborns with respiratory failure.

Laparoscopic vs percutaneous endoscopic gastrostomy tube insertion: a new pediatric gold standard?
Gastrostomy tube insertion is frequently performed in children. Percutaneous endoscopic gastrostomy (PEG) insertion, considered by many to be the "gold standard," is unavoidably associated with a risk of intestinal perforation and frequently requires a second anesthetic for its replacement with a low-profile "button." We hypothesized that a laparoscopic technique with low-pressure insufflation would yield comparable outcomes, a lower procedural complication rate, and require fewer anesthetics per patient. ⋯ Laparoscopic gastrostomy tube insertion is safe and easy to perform, with outcomes comparable to that of PEG tube insertion. It obviates the need for a second procedural anesthetic and may emerge as the gold standard for gastrostomy tube placement.

Since the introduction of the closed technique for repair of pectus excavatum, increasing numbers of patients are presenting for surgery. However, controversy exists regarding the effects of repair on long-term cardiopulmonary outcome. This report details the effects over time of closed repair of pectus excavatum on pulmonary function, cardiac function, exercise tolerance, and the patient's perception of appearance and subjective ability to exercise. ⋯ These results corroborate previous studies which suggested that after closed repair of pectus excavatum there is an immediate subjective improvement in the ability to exercise which is paralleled by an improvement in cardiac output. However, there is an early postoperative decline in pulmonary function which does improve over time; however, this does not reach normal values for similar weight. Further studies are needed to determine whether these results are maintained, or whether after bar removal there is a further improvement in pulmonary status. These results do support the use of the closed repair of pectus excavatum for maintaining and possibly improving cardiopulmonary function in this patient population.
