Abstract
While the number of patients at risk for vomiting and aspiration has been reported to be high, the incidence of clinically important pulmonary aspiration is low. We sought to define the incidence of gastroesophageal reflux (GER) and to correlate this with the clinical variables of obesity, history of oesophagitis, bucking and changes in body position. Continuous oesophageal pH measurement was used to determine the frequency of gastroesophageal reflux in 44 patients having general anaesthesia for elective surgical procedures. Acid reflux to a pH value of less than four occurred in seven patients (15.9%) during anaesthesia. This was associated temporally with straining on the endotracheal tube in six subjects (13.6%). We conclude that traditional risk factors are not always predictive of those patients at risk of regurgitation and aspiration. L’incidence actualle d’aspiration pulmonaire d’importance clinique est faible malgré le nombre imposant de patients présumés à risque de vomissements et d’aspiration. Nous avons tenté de déterminer l’incidence du reflux gastro-oesophagien (GER) et d’évaluer sa corrélation avec les variables cliniques suivantes: obsésite, histoire d’oesophagite, toux (« bucking ») et changement de position corporelle. Des mesures continues du pH oesophagien ont été utilisées afin de déterminer la fréquence du reflux gastro-oesophagien chez 44 patients subissant une anesthésie générale pour une intervention chirurgicale non urgente. On a obsreve un reflux acide avec un pH de moins de 4 chez sept patients (15,9%) pendant l’anesthésie. Ce reflux survenait simultanément à un effort de rejet du tube endotrachéal chez six sujets (13,6%). En conclusion, les facteurs de risque traditionnels ne suffisent pas toujours pour prédire quels patients sont en danger de régurgitation et d’aspiration.Keywords
