Abstract Background: The transversus abdominis plane (TAP) block is a known approach for blocking the abdominal wall neural afferents via the bilateral lumbar triangles of Petit. Different adjuvants have been used to intensify the quality and the duration of local anesthetics. We evaluate adding magnesium sulfate to Bupivacaine as a post operative analgesic after umbilical hernia operation Aim of the Work: The aim of this study is to detect the efficacy and safety of magnesium sulphate as an adjuvant to the analgesia offered by local anesthetic in ultrasound guided TAP block in patients undergoing surgical repair of moderate sised umilical hernia. We designed this study to evaluate the effect of adding magnesium sulphate to bupivacaine.25 %in the ultrasound-guided TAP block anesthesia after open appendectomy operation, As regard postoperative pain block and opiod consumption using Visual Analogue scale VAS. Patients and Methods: Type of Study: Prospective double blinded randomized controlled trial. Study Setting: Ain Shams University Hospital, Cairo, Egypt. Study Period: 6 months. Study Population: the study was carried out on 40 patients who was undergo sirgical Eligibility Criteria: Age: 18-40 years. Physical status: ASA I,II. Both sexes. BMI<35 Results: In our study we workout on 40 patient with moderate size umbilical hernia 20 patient receive post operative analgesic TAP block with Bupivacaine 0.25% (20ml) and other 20 patient receive post operative analgesic TAP block with Bupivacaine 0.25% 18ml and 200mg (2ml) Mgso4. Conclusion: MgSO4 as an adjuvant to Bupivacaine in Ultra-sounded guided TAP block reduces post-operative pain scores, prolong the duration of analgesia and decreases demand for rescue analgesics. |
