NAUSEA AND VOMITING AFTER GYNECOLOGICAL LAPAROSCOPY DEPENDS UPON THE PHASE OF THE MENSTRUAL-CYCLE

Postoperative nausea and vomiting were compared in 68 women with regular menstrual periods undergoing gynaecological laparoscopy. The patients were divided into four groups on the basis of the phase of the menstrual cycle as follows: premenstrum-menstrum (pre + menstrum) (Pd 25-6), early follicular phase (Pd 8-12), ovulatory phase (Pd 13-15) and luteal phase (Pd 20-24). The overall incidence of nausea and vomiting was 46%. Statistically significant differences in the incidence of nausea and retching were found among the groups by regression analysis. The incidence of nausea and vomiting was highest in women undergoing laparoscopy during the luteal phase (77%), which was greater than during the follicular phase (32%) or during pre + mensturation (18%). The need for antiemetic was highest in women undergoing laparoscopy during the luteal phase (69%) and this was different from the follicular (18%, P < 0,01) and pre + menstrum (19%, P < 0,01) phases. It is concluded that the highest incidence of postoperative nausea and vomiting after gynaecological laparoscopy occurs during the luteal phase.
