Intestinal smooth muscle response to chronic obstruction : possible applications in jejunoileal atresia.

Hyperplasia is the main change occurring in intestinal smooth muscle above a chronic obstruction and explains the functional obstruction seen in the proximal bowel of a jejunoileal atresia. With an experimental model in dogs, this hyperplasia has been shown to be reversible. However, changes are extreme in atresia, and experiments in animals with induced atresia will best evaluate various kinds of treatment.

Pumpless respiratory assistance using a membrane oxygenator as an artificial placenta: a preliminary study in newborn and preterm lambs.

Newborns suffering from severe respiratory difficulties and not responding to conventional methods have been successfully treated by extracorporeal circulation with a membrane oxygenator (ECMO). However, the technique needs a highly specialized staff, excellent laboratory support, and continuous surveillance of the procedure to prevent complications. In a series of experiments on newborn and preterm lambs, we have investigated a relatively simpler technique of respiratory support that involves a pumpless arteriovenous bypass by cannulating both umbilical arteries and the umbilical vein. A highly efficient microporous membrane oxygenator (MO) with very low resistance was selected. This type of perfusion that mimics the placental circulation, besides providing an additional amount of oxygen to the blood, has proven to be very effective for CO2 extraction. Before its application in humans, however, improvements in the catheters to be inserted in the umbilical vessels, some modifications in the design of the MO, and improvements in the blood compatibility of all foreign surfaces in contact with blood are needed.
