| Background Postoperative pain after laparoscopic cholecystectomy still remains a fairly common challenge for the anesthesiologist. Commonly used drugs such as NSAIDs and opioids have their own side effects requiring a need to substantially evaluate the use of non-pharmacological methods like TENS as adjuvants to conventional methods of pain control. We studied the effect of transcutaneous electrical nerve stimulation (TENS) on postoperative pain in laparoscopic cholecystectomy. The primary objective was to compare postoperative analgesia between TENS and placebo groups using visual analog scale (VAS). The secondary objectives were to compare the requirement and dosage of rescue analgesia, hemodynamic parameters (blood pressure and heart rate), and incidence of nausea and emesis between placebo and TENS groups. A total of 64 patients of age group 18 years to 60 years of either gender posted for elective laparoscopic cholecystectomy were randomly allocated into two groups using a computer-generated sequence of random numbers: Group P (= 32): placebo TENS and Group A (= 32): active TENS. Statistical analysis was performed by the SPSS program for Windows, version 17.0 (SPSS, Chicago, Illinois). Unpaired test, Mann-Whitney test, chi-square test, and Fisher’s exact test were used for statistical analysis. Results The two groups were statistically similar in terms of age, gender, and weight. The VAS scores were significantly lower in patients in the active TENS group for up to 2 h after surgery, and the total weighted dose of diclofenac consumed over 8 h in the active TENS group was significantly lower as compared to the placebo TENS group. Patients who received TENS showed significantly less rise in blood pressure and heart rate and remained hemodynamically stable. Total episodes of nausea and emesis though less in the active TENS group were statistically insignificant. Conclusion We conclude that TENS is an effective adjuvant non-pharmacologic modality for postoperative pain relief after laparoscopic cholecystectomy. | ||||
