Evaluating the effectiveness of TENS for maternal satisfaction in laboring parturients – Comparison with epidural analgesia

Background and Aims: Labor pain is one of the most severe pain that a woman experiences in her lifetime. Various methods are being used to relieve this pain and to achieve higher maternal satisfaction. One such technique is transcutaneous electrical nerve stimulation (TENS) that uses low-frequency electrotherapy. The aim of our study was to evaluate TENS by comparing it to an established labor analgesia technique, i.e., epidural analgesia in terms of maternal satisfaction. Material and Methods: This prospective study was conducted on 60 parturients in active stage of labor. The choice of analgesia was made by the parturient after informed consent. In group A (n = 30) TENS was used, while in group B (n = 30) epidural ropivacaine 0.125% + 2 μg/ml fentanyl was given. Continuous monitoring of maternal vitals, visual analogue score, and fetal heart rate (FHR) was done. Maternal satisfaction was scored considering pain relief, ability to move and experience of labor at the end of delivery and outcome was labeled as favorable and unfavorable. Results: TENS was found to be favorable in 90% of parturients as compared to 96.6% in epidural (P 0.301). The number of highly satisfied parturients was 4 (13.3%) in TENS group and 17 (56.6%) in the epidural group (P= 0.000). Three patients in the epidural group had assisted delivery and two had cesarean section whereas all patients in TENS group delivered normally (P= 0.065). No significant difference was found in the fetal outcome. Conclusions: TENS is a good alternate choice for providing labor analgesia and may have a major role in future.
