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

摘要

This study was to evaluate the impact of different preoperative fasting conditions on women and neonates through a retrospective analysis. 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??6?h; C: solid food ≥6?h??8?h; clear fluids ?2?h; D: solid food ≥2?h??6?h; clear fluids ?2?h; E: solid food ?2?h; clear fluids ?2?h. Incidence rate of vomiting of women was lower in group C (solid food ≥6?h??8?h and clear fluids ?2?h) than other groups (P??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. 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.
