Introduction: Postoperative nausea and vomiting of one of the most frequent adverse effects in the postoperative period, with an incidence of up to 70%. Dexamethasone administered alone or in combination with other antiemetics is effective as a prophylaxis for postoperative nausea and vomiting. Material and Methods: It is a prospective, observational, cross-sectional, descriptive study conducted in 48 female patients, sometimes an elective cesarean section with diagnosis of gestational diabetes that meet the selection criteria. Results: 48 women of 27.9 ± 6.0 years with a diagnosis of gestational diabetes who sometimes went to cesarean delivery were included. A case of nausea was reported at baseline measurement (2.1%), however, the incidence of nausea, vomiting and a second antiemetic requirement was 0%. Insulin administration was required in 4 patients, 1 (2.1%) at recovery, 2 (4.2%) at 4 hours and 1 (2.1%) at 24 hours. Conclusions: In our study we were able to completely prevent the incidence of nausea and vomiting by co-administering it with metoclorpramide. Both are drugs of low cost and with greater accessibility than 5HT-3 antagonists, so it can be a useful alternative in practice for the prevention of nausea and vomiting.
