Core Tip

Core Tip: The study included 82 patients who reported gastroesophageal reflux (GER) and 519 patients without GER. The results of multivariate logistic regression indicated sex, increased age, pharyngitis, and history of GER were associated with increased risk of GER, whereas the use of propofol could protect against the risk of GER. Finally, age, operative time, pharyngitis, history of GER, and hypertension were significantly associated with GER time.
