Effect of Para-Incisional and Zusanli Point Electrical Stimulation on Pain Medication Requirements in Post Inguinal Herniorraphy

Abstract

Backgr ound: Using oftranscutaneous electrical nerve stimulation TENS to relieve postoperative pain still an important and growing area of research. The pro er location of TENS electrodes is not been well investigated. Tfte purpose: of the study was to investigate the effect of Para. Incision and stimulation of special acupuncture point (Zusanli) with electrical stimulation on acute pain. Subjects: Forty patient whom underwent elective inguinal hemiorraphy were included in current study. Their ages ranged from 30 years old to 50 years old, among this number only 3 patients were females. They were chosen from the surgical ward of Monouf general hospital and were randomly and equally assigned to four groups. Metltods: Group A, received electrical stimulation ES on Zusanli (Stomach. 36), group B, received ES on paraincisional. Group C, received ES on Zusanli (St. 36) and paraincisional at the same time and group D, received sham ES on the same location as group A. All groups were stimulated using an adhesive surface electrodes. The consumption of pain medication requirements (opioids and nonsteroidal antiinflamatory drugs) were calculated for each patient. Results: The results showed that the requirements for pain medication were significantly reduced among groups A, and B, p = 0.025 and it was significant reduced in group C, p = 0.0001. Discussion and conclusion: The findings revealed that the best location of TENS electrodes to reduce pain medication requirements postoperatively was on the paraincisional and Zusanli (St. 36) at the same time.
