ABSTRACT

Objectives: The electrical transcutaneous stimulation (TENS) is a relatively new technique, that is useful in the management of different types of pain, included the labor pain; we decided to evaluate high and low frequency TENS for the relief of pain labor. Material and Methods: 48 patients with active labor were studied. 6 silicon-carbon electrodes were applied at lumbar, sacral and suprapubic region, and stimulated with the equipment Accupoint 2000, beginning with a TENS stimulation program (as recommended by the manufacturers), which was characterized by a frequency of 6 Hz during 15 minutes, the followed with the program called disperse-continuous stimulation, which consisted in stimulation similar to the acupuncture and the conventional, each one with a duration of 0.8 sec at 6 Hz and 80 Hz respectively, which was kept during all the labor. Analogous visual scale (AVS) and the analogous verbal scale (AVERS) were used to register the intensity of the pain. Fetal heart rate and maternal arterial pressure were also evaluated.Results: A significative pain relief was obtained with TENS with no changes in maternal arterial blood pressure or fetal heart rate. Conclusions: Transcutaneous electrical nerve stimulation is an adequate alternative for patients not accepting epidural blockade or in which is contraindicated.
