INFLUENCE OF RITODRINE ON PLACENTAL METABOLISM OF LIPID IN PRETERM DELIVERIES

The goal of this study was to investigate the action of ritodrine hydr ochloride on placental lipid metabolism in preterm deliveries. Eightee n placentas from preterm deliveries were anlayzed. Group I consisted o f ten preterm deliveries in which iv ritodrine hydrochloride had been administered. All patients received intravenous infusion of 150 mg rit odrine (Pre-par) in 500 ml of 5% glucose solution. Group II consisted of eight preterm deliveries in which no tocolysis had been administere d. Ritodrine administration as tocolysis leads to evelvation of total placental lipid contents. At the same time, the concentrations of phos pholipids and free fatty acids increase.
