Official title
Comparison of Intrathecal Versus Epidural Fentanyl: Effect of Neuraxial Route of Administration on Fetal Bradycardia in Labor Combined Spinal Epidural Analgesia
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
There have been studies reporting that combined spinal-epidural (CSE) with fentanyl and bupivacaine produce fetal bradycardia, (M.Kuczkowski, 2004) (Abrão K, 2009 ). It is unknown whether any differences in risk exist between fentanyl and bupivacaine when used as a part of the CSE procedure. Some authors have reported cases of parturients who developed uterine hyperactivity and fetal bradycardia after subarachnoid administration of fentanyl during labor. (D'Angelo \& Eisenach, 1997) (Friedlander JD, 1997). It has been suggested that uterine hypertonus, leading to non-reassuring fetal heart rate tracings, might be an etiologic factor in these situations. (Landau, 2002). We propose this study to test the hypothesis that administration of epidural fentanyl is associated with a lower incidence of fetal bradycardia compared to intrathecal fentanyl.
