Abstract
Applied potential tomography was used to measure changes in gastric emptying during the peripartum period. Gastric emptying was measured sequentially in each of 10 healthy patients at 37-40 weeks gestation, 2-3 days postpartum and after the 6-week postnatal assessment (control). Mean (SD) times to 50% emptying were 15 (6.05), 11 (5.9) and 15 (5.5) min, respectively. There was no statistically significant change in gastric emptying as a result of pregnancy in this group of women. Retrospective power analysis (assuming alpha = 0.05 and beta = 0.20) shows the study design was adequate to detect a difference of 8 min.Entities:
