Abstract

The analgesic affects of TNS, pethidine and placebos on labour pain were studied in 30 parturient women during the first stage of labour. 10 had TNS paravertebrally in the region of the afferent nerves at Th 10-Th 12; one group of 5 had unspecific (wrong) TNS; in another group of five no current was applied (placebo); five women were given 50 mg of pethidine intravenously; five patients acted as a control group. To assess the analgesic effects the women were asked to estimate the intensity of pain (grades 1-6) over a period of 70 minutes. There was no significant difference between the placebo, unspecific TNS and control groups as regarded the increase in pain during the test period. Patients who had received pethidine and those who had been given TNS at the site of the afferent nerves transmitting impulses from the uterus experienced considerable relief of pain. The differences were highly significant. The observations prove the genuine analgesic action of TNS. The use of this technique in obstetrics is discussed.
