Studies show that epidurals are more effective painkillers than intravenous narcotics, another common pain-relief method. Another benefit is that if complications arise and emergency interventions are needed, it is helpful to have the epidural in place, ready to dispense additional medications. It still controls pain, but allows women more mobility than a traditional epidural, which prohibits walking. Disadvantages Dangerous side effects are rare. But there are several less-serious effects to consider.
Epidurals seem to prolong labor.
Doctors often counter that effect with pitocin, a hormone that accelerates labor. They have also been linked to an increase in births involving C-sections, vacuum aspiration and forceps. A fairly common side effect of an epidural is low blood pressure, often accompanied by nausea, vomiting and dizziness. This is usually averted by giving the woman intravenous fluids before the epidural. Occasionally, epidurals cause backaches and headaches.
