Placental transport of metoclopramide: Assessment of maternal and neonatal effects

Twenty-three patients undergoing general anaesthesia for Caesarian section for healthy term pregnancies were entered into a double blind study using metoclopramide (MCP) and a normal saline placebo. Of these patients, eight received intravenous metoclopramide, 12 a normal saline placebo and three were lost to clinical follow-up. The maternal gastric volumes were measured and maternal and foetal MCP plasma concentrations were determined by gas-liquid chromatography. The Neurological and Adaptive Capacity Score tests of Amiel, Barrier and Schnider (NACS) were used to attempt evaluation of neonatal responses to MCP Maternal gastric volume was significantly lower (p < 0.05) in the treated patients.
