Abstract
the third common disease in surgeries for adult after acute appendicitis and proctologic disorders. About 20 millions of inguinal hernia repairs are performed globally. Inguinal herniorrhaphy is frequently associated with persistent postoperative pain. A significant proportion of pain experienced by patients undergoing abdominal surgeries is related to somatic pain signals derived from the abdominal wall.
Aim of the work: The aim of this study is to assess the postoperative analgesic efficacy of Magnesium sulfate added to Bupivacine verus Morphine to Bupivacaine in ultrasound guided transversus abdominis plane (TAP) block after inguinal herniorraphy regarding the pain relief and the amount of rescue analgesia used postoperative.
Patients and Methods: The study was conducted on 45 randomly chosen patients in Ain Shams University Hospitals after approval of the medical ethical committee. They were allocated in three groups of 15 patients each: group - I (B): received TAP block with Bupivacaine only as a “Control Group”. group - II (B-MO): received TAP Block with Bupivacaine plus Morphine. group - III (B-Mg): received TAP block with Bupivacaine plus Magnesium Sulfate. The three groups were adequately monitored and assessed intra- and post-operatively and they were compared regarding analgesic outcome by using the visual analogue scaling system, besides, recording time for first call for rescue analgesia and total consumption of it in the 1st 24 postoperative hours. Demographic data and post-operative hemodynamics were also assessed.
Results: The results of the study revealed that Magnesium added to bupivacaine better than Morphine added to Bupivacaine in transversus abdominis plane block regarding the postoperative analgesia after inguinal Herniorraphy.
Conclusion: In Conclusion the addition of MgSo4 as an adjuvant to bupivacaine in TAP block has shown superiority over either mono-therapy with bupivacaine or bupivacaine-Morphine combination in many aspects such as postoperative analgesic outcome assessed by VAS score , 1st time of rescue analgesia and without the pronounced side effects of the conventional postoperative opioids and less side effect than Morphine.
