description | Objective To evaluate fetomaternal bleeding following routine cesarean delivery compared with cesarean delivery involving transplacental transection. Study Design A prospective cohort study evaluating cesarean delivery in which the placenta was transected (cases) versus controls (placenta not transected) from January 2016 to April 2018. A maternal Kleihauer–Betke's (KB) test and newborn hematocrit were performed shortly after delivery. Results The rate of a positive KB test was not significantly different between cases ( n = 31) and controls ( n = 61) (19 vs. 14%; odds ratio [OR]: 1.44; 95% confidence interval [CI]: 0.46–4.49; p = 0.74). Median neonatal hematocrits were not different. However, the rate of newborn hematocrits <40% at delivery was higher in cases compared with controls (23 vs. 3%; OR: 8.90; 95% CI: 1.72–45.90; p = 0.005). Conclusion A cesarean requiring transplacental transection to accomplish delivery does not significantly increase the rate of fetomaternal bleeding but is associated with a higher likelihood of newborn hematocrit <40% at delivery. |
