Abstract:
Objective:To identify the risk factors for delayed gastric emptying in patients scheduled for elective caesarean section.Methods:One hundred and five patients, aged≥18 yr, at≥37 week gestation, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective caesarean section from August 2023 to February 2024, who followed the preoperative fasting guidelines, were collected. Based on the quantitative and qualitative ultrasound assessments of the gastric antrum, patients were divided into 2 groups: delayed gastric emptying group, as defined by Perlas A score of grade 2 or the presence of solid contents or gastric volume/weight >1.5 ml/kg, and non-delayed gastric emptying group, as defined by Perlas A score < grade 2 and gastric volume/weight ≤1.5 ml/kg. The variables of which showed statistically significant differences in the intergroup comparison would enter the logistic regression analysis to stratify the risk factors for delayed gastric emptying before elective caesarean section.Results:There were 41 parturients (39.0%) showed delayed gastric emptying before elective caesarean section. According to the results of multifactorial logistic regression analysis, the gastroesophageal reflux disease( OR=5.313, 95% confidence interval 1.013-27.878, P=0.048) was an independent risk factor for delayed gastric emptying in the patients who underwent elective caesarean section. Conclusions:Gastroesophageal reflux disease is an independent risk factor for delayed gastric emptying in the patients scheduled for elective caesarean section.
