Factors affecting fetal bradycardia following combined spinal epidural for labor analgesia: a matched case-control study.

Purpose The combined spinal epidural (CSE) technique for labor analgesia has become increasingly popular owing to its rapid onset of analgesia. However, incidences of fetal bradycardia following CSE have been reported. This study aimed to identify predictors of fetal bradycardia post CSE, such as a decrease in pain scores, the block height, Prostin (dinoprostone; Pfizer) use, and dosage of oxytocin.
