Influence of different preoperative fasting times on women and neonates in cesarean section: a retrospective analysis

Abstract

Abstract Background This study was to evaluate the impact of different preoperative fasting conditions on women and neonates through a retrospective analysis. Methods A total of 1599 women were divided into 5 groups according to different preoperative fasting times: group A: solid food ≥8 h; clear fluids ≥6 h; B: solid food ≥8 h; clear fluids ≥2 h 8 h and clear fluids > 2 h at least), the incidence rate of hypoglycemia and acidosis of neonates in group C displayed a certain decrease (P < 0.05). Although shorter fasting times (solid food < 6 h at least) reduced the incidence of hypoglycemia and acidosis in neonates, it increased the risk of vomiting of women. Conclusion The preoperative fasting of solid food ≥6 h < 8 h and clear fluids < 2 h reduces the incidence of vomiting in women’s anesthesia and the risk of hypoglycemia and acidosis in neonates.
