A controlled trial of antiemetics in abortion by PGF2alpha and laminaria.
Women undergoing abortion by intraamniotic prostaglandin F2alpha were randomized to receive either prochlorperazine edisylate 10mg, hydroxyzine hydrochloride 100mg, or a placebo every four hours by intramuscular injection in a double-blind fashion. Vomiting was significantly more frequent in the placebo-treated group [0.2 +/- 1.5 SD episodes per patient, n=21]  than in the groups treated with prochlorperazine [1.2 +/- 0.5 episodes per patient, n=21] or hydroxyzine [0.3 +/- 0.8 episodes per patient, n=19]. The mean number of merperidine injections in the antiemetic-treated groups was lower than in the control group, but this effect was not statistically significant. There was no significant difference between the treated and the control groups in the interval from prostaglandin treatment to abortion.
