Abstract
The aim of this retrospective study is to determine the predictive factors of postoperative dyspnea in infants with Pierre Robin sequence (PRS). Forty children with PRS, who underwent general anesthesia, were retrospectively analyzed. The patient's physiological status and anesthesiology data were collected accordingly, demographic characteristics including age, gender, height and weight at surgery, weight gain, preoperative airway status, tracheal intubation route, American Society of Anesthesiologists grading and airway Cormack-Lehane classification. Weight gain, dyspnea before the operation, Cormack-Lehane grade distribution showed a significant difference between patients with and without postoperative dyspnea (p = 0.0175, p = 0.0026, and p = 0.0038, respectively). Incompetent weight gain was identified as a predictor (p = 0.0371) of PRS postoperative dyspnea through the binary logistic regression model. In conclusion, this study established an early alerting model by monitoring the weight gain, dyspnea before the operation, Cormack-Lehane grade as potential combinations to predict the risk of postoperative dyspnea for PRS.
