A gastric tube with esophageal balloon was designed for neonatal use. The response of the balloon was evaluated. In vitro studies involved comparisons of pressure changes (delta P) in a flask, as measured directly, or as transferred via the balloon. ⋯ The delta s measured via the balloon were frequently equal to or sometimes minimally lower than the actual pleural pressure changes. The prototype meets recommended dimensions for esophageal balloon use in the neonate and allows for accurate routine measurements for calculation of pulmonary function. The device is now available commercially.

Is there a role for fetal cephalocentesis in modern obstetrics?
Obstetricians have traditionally viewed fetal hydrocephalus with resultant macrocephaly as a dismal condition with little chance for a good outcome. Cephalocentesis with decompression of the fetal head in order to permit vaginal delivery has often been the management of choice. In view of the significant perinatal consequences of cephalocentesis and the changing outlook for optimally managed neonatal hydrocephalus, the authors reassess the role of cephalocentesis in modern obstetrics.
