2001 AUG 9 - (NewsRx Network) -- Epidural techniques which use low-dose anesthetics reduce the need for assisted vaginal delivery in childbirth, casting doubt over the future use of conventional epidurals, conclude authors of a study in the July 5, 2001, issue of the Lancet.
Epidurals are the most effective form of pain relief during childbirth. But they are associated with increased rates of instrumental vaginal delivery and associated complications, which might be related to poor motor function, which prevents mothers from pushing during labor. New techniques that preserve motor function could reduce obstetric intervention.
Andrew Shennan and Christine MacArthur led a team of investigators who did a randomized, controlled trial to compare two low-dose epidural techniques - combined spinal epidural (injection into the spinal fluid followed by epidural top-ups) and low-dose infusion (epidural given continuously using a pump) - with traditional epidural techniques.
The investigators randomly assigned 1054 women requesting epidural pain relief to traditional epidural, low-dose combined spinal epidural, or low-dose infusion epidural. The primary outcome was mode of delivery; secondary outcomes were progress of labor, efficacy of procedure, and the effect of the type of epidural on the newborn.
The rate of normal vaginal delivery increased (from around 35% to 43%) in both the low-dose combined spinal epidural group and in the low-dose infusion group compared with women given traditional epidural. However, babies whose mothers were given low-dose epidural took ...
