简要总结
| Brief Summary |
The present study will be conducted in the Department of Anaesthesia and Intensive Care, Government Medical College and Hospital, Chandigarh in collaboration with the department of Orthopaedics, Government Medical College and Hospital, Chandigarh. After approval from the Hospital Ethics Committee and registration with Clinical Trial Registry India, 90 patients of American society of Anesthesiologists (ASA) physical status I &II of either sex, aged between trauma will be enrolled.
Study design- Prospective, randomized, double blind and placebo controlled trial.
The primary outcome measures will be to study tramadol sparing effect in patients receiving dexmedetomidine as adjuvant in adductor canal and sciatic popliteal nerve block in patients undergoing below knee trauma surgeries.
The secondary outcomes will be to study the hemodynamics, VAS at rest and on movement, Ramsay Sedation scale Quadriceps muscle strength, rescue analgesia adverse effects patient satisfaction score, length of hospital stay and follow up at three months (telephonically) in patients receiving adductor canal block and sciatic popliteal nerve block following below knee surgeries.
Sample size was calculated on the basis of pilot cases conducted in the department of Anaesthesia and Intensive Care, Government Medical College and Hospital, Chandigarh. It was observed that the mean tramadol consumption in the patients receiving ropivacaine in the ACB and SPB (control group) was 106.60 mg with a standard deviation of 37.40 mg. Considering a difference of 30 % in tramadol consumption in study group as compared to control group as statistically significant, with an effective size of 0.34, the required sample size came out to be 27 patients per group at a power of 80%. To compensate for dropouts, we decided to include 30 patients per group. So, the total sample size of our study will be 90 patients.
