Management
In a prospective comparative study [PMID:35103759], the fraction of gastric emptying at 90 minutes was notably reduced in parturients receiving epidural analgesia (31%) compared to nonpregnant women (52%), pregnant women without analgesia (45%), highlighting the need for careful fasting guidelines in this population.
The study [PMID:35103759] found that gastric emptying in pregnant women without labor analgesia was significantly slower (45% at 90 minutes) than in nonpregnant women (52%), indicating potential considerations for fasting protocols.
Special Populations
The research [PMID:35103759] demonstrated that parturients with epidural analgesia had the lowest gastric emptying fraction (31% at 90 minutes), suggesting tailored fasting recommendations are necessary for this special population to prevent aspiration risks.
