title: [Prevention of acute neonatal respiratory insufficiency. A method of conditioning the baboon lung during cesarean section].
abstract: Preterm baboons at 140 +/- 3 day gestation (term 182 +/- 7 days) have been subjected to lung conditioning, consisting of a series of prolonged inflations of the lungs at 35 cm H2O, followed by approximately 10 min of application of continuous positive airway pressure (CPAP) equal to 15-20 cm H2O, before umbilical cord interruption. The aim of this study was to evaluate, in a primate experimental model, the safety and efficacy in the prevention of neonatal RDS of a technique so far experimented on only in ovine models. Thoraco-pulmonary compliance exceeded the value of 0.2 ml (cm H2O)-1.kg-1 in only 1 animal out of 5 (20%), which didn't develop illness, versus 69% of positive results achieved with the same technique in lambs at 128-130 day gestation, an experimental model considered in the literature as equivalent to a 140 +/- 3 day gestation baboon as far as it concerns incidence and severity of RDS. The application of lung conditioning was easy and safe (as previously reported), but its effectiveness in a primate model is still to be defined.
