AbstractNausea and vomiting are common complaints in the postoperative period and contribute to patient distress and delay of discharge for outpatient surgical procedures. Laparoscopic procedures are associated with a high incidence of postoperative nausea and vomiting (PONV) episodes. Parenteral use of metoclopramide prevents and treats PONV. The intranasal route provides rapid and complete absorption of metoclopramide without many of the adverse effects observed with parenteral administration of the drug. We performed a prospective, double-blinded, randomized, placebo-controlled study to evaluate the safety and efficacy of metoclopramide 20 mg administered intranasally for emetic prophylaxis in laparoscopic surgery patients. The results from 109 patients enrolled in the study showed that this intranasal dose of metoclopramide may be ineffective in preventing the occurrence of PONV. The poor performance of the intranasal metoclopramide formulation in this study cannot be attributed to patient-specific and perioperative factors. It may be due to an inadequate dose or slow absorption of the drug. The small sample size, however, may also have been a factor.
