[Diaphragmatic hernia: the role of perioperative resuscitation]

Twenty-nine newborn infants with diaphragmatic hernia have been received in a neonatal intensive care unit over a seven year period. In three cases, clinical signs appeared after the first day: they all survived. Six infants died before surgery: five of them had major pulmonary hypoplasia. Surgery was performed in twenty cases: nine of these infants died. Death occurred during the first twelve post-surgical hours in six cases with major pulmonary hypoplasia. Fourteen infants were followed from 6 to 24 months; two developed post-anoxic hydrocephaly with poor neurological development in one case. A pH above 7.1 and an adequate hemodynamic status obtained before surgery are simple criteria of a good prognosis. When these criteria are not obtained, prognosis is poor as they are in favor of major pulmonary hypoplasia.
