[Prophylactic anti-emetic strategy: prevention among obstetrician-gynaecologists anaesthesia]. / Prévention des nausées et vomissements postopératoires : enquête sur les pratiques en chirurgie gynécologique auprès des membres du Club d'anesthésie réanimation en obstétrique.

ABSTRACT

OBJECTIVES: A prophylactic anti-emetic strategy should depend on the number of nausea and vomiting risk factors. This study was undertaken to evaluate the practices of postoperative nausea and vomiting (PONV) prevention practices among obstetrician-gynaecologists, anaesthetists. STUDY DESIGN: A prospective, self-administered questionnaire survey was emailed to all Club d'Anesthésie Réanimation Obstétricale (Caro) members (French Obstetric and Gynaecology Anaesthetists' Association). METHODS: The questionnaire had closed-ended questions to evaluate each Caro member's prophylactic anti-emetic practices. Questions concerned demographic datas, prophylactic anti-emetic drugs administered to the patients with or without well known risk factors for developing PONV, the existence of protocol to prevent PONV in their own department of anaesthesiology and their awareness of the existence of French Society of Anaesthesia and Intensive Care (Sfar) PONV prevention guidelines 2007. RESULTS: Of 115 questionnaires, 66 respondents (57%) returned the questionnaires. Most of the respondents (74%) worked in a university hospital. Forty-two percent practiced exclusively in obstetric-gynaecology department. Fifty-six percent were anaesthetists for more than 20 years. Eighty-five percent of the physicians were well-informed about the SFAR's PONV prevention guidelines. Thirty seven percent of respondents assessed Apfel score systematically for all their patients. The percentages, which didn't calculate the probability of PONV with Apfel score or calculated only in cases of PONV history or travel sickness were 18% and 45% respectively. In cases of two or more risk factors, 63% used droperidol, dexamethasone and ondansetron in double or triple combinations. CONCLUSIONS: Although most surveyed practitioners were well informed about the new guidelines concerning PONV prevention, 27% not follow these guidelines regarding the administration of anti-emetic drugs. The calculation of Apfel score in the preoperative period must be also strengthened.
