Does lumbar epidural analgesia with bupivacaine affect fetal scalp blood pH, drug concentration, and fetal heart rate in women during uncomplicated labor?
Lumbar epidural analgesia with bupivacaine during uncomplicated labor appears safe for the fetus, maintaining normal fetal scalp blood pH and low fetal drug concentrations without causing pathologic fetal heart rate changes.
