Abstract
The efficacy of aspiration of gastric contents to reduce post-operative nausea and vomiting was investigated in a controlled randomized, double-blind study of 265 outpatients. Patients in the treated group had their stomachs aspirated with an orogastric tube. In the control group no tube was inserted. Data on the incidence of nausea and vomiting were collected in the recovery room, the day surgery unit and the day after surgery. The overall incidence of postoperative nausea and vomiting was comparable in the two groups. It was also comparable in the recovery room and the day surgery unit. However, treated patients had a higher incidence of both nausea (26.5% vs 12.0%,P < 0.005) and vomiting (16.7% vs 6.8%, P < 0.02) after their discharge from the day surgery unit. We conclude that aspiration of gastric contents with an orogastric tube does not decrease postoperative nausea and vomiting in outpatients and may increase it after discharge of the patient.
Résumé
L’efficacité de l’aspiration du contenu gastrique dans le but de réduire l’incidence des nausées et des vomissements post-opératoires a été évaluée au cours d’une étude contrôlée ran-domisée à double insu chez 265 patients dans un centre de chirurgie d’un jour. L’estomac des patients du groupe traité a été aspiré avec une sonde gastrique alors que dans le groupe témoin on n’a pas inséré de sonde. Les données concernant l’incidence des nausées et des vomissements ont été recueillies à la salle de réveil, à l’unité de chirurgie d’un jour et le len-demain de la chirurgie. L’incidence totale des nausées et vomissements fut comparable dans les deux groupes. Il n’y a pas eu non plus de différence à la salle de réveil et à l’unité de chirurgie d’un jour. Cependant, les patients traités ont présenté une incidence plus élevée de nausées (26,5% vs 12,0%,P <0,005) et vomissements (16,7% vs 6,8%, P < 0,02) après leur départ de l’unité de chirurgie d’un jour. Nous concluons que l’aspiration du contenu gastrique ne diminue pas l’incidence des nausées et vomissements postopératoires chez les patients de chirurgie d’un jour. En réalité, cette manoeuvre semble augmenter l’incidence de cette complication après le départ de l’unité chirurgicale.
