Background: Magnesium sulphate (MgSO4) N methyl D aspartate receptor antagonist has the potential to be an ideal adjuvant for postoperative analgesia via intrathecal or intravenous route. The aim of the study was, we compared the efficacy of two routes of MgSO4 (Intravenous vs intrathecal) as an adjuvant to bupivacaine in subarachnoid block (SAB).Methods: Ninety, American Society of Anesthesiologists physical status 1 or 2 patients, aged 20-60 years, scheduled for hip surgeries under SAB were recruited in department of Anaesthesia and Dept. of Orthopaedics. Patients in group 1 (n=29) received intrathecal 0.5% (H) bupivacaine 15 mg with 0.1 ml of normal saline and 250 ml 0.9% normal saline intravenous 30 minutes before giving SAB. Group 2 (n=30) patients received intrathecal 0.5% bupivacaine 15mg with 0.1 ml of normal saline and 50mg/kg of magnesium sulphate in 250 ml normal saline intravenous 30minutes before giving SAB. In Group 3 (n=30) patients received intrathecal 0.5% (H) bupivacaine 15 mg with 50mg (0.1ml) magnesium sulphate and 250 ml 0.9% normal saline intravenous 30 minutes before giving SAB. They were evaluated for block characteristics, visual analogue scale at various time intervals up to 24 hours and total rescue analgesic and duration of postoperative analgesia were noted.Results: Intravenous magnesium sulphate had maximum pain free interval, lower pain scores, longer sensory and motor blockade and less requirement of rescue analgesia as compared to the patients in intrathecal group or control group (P<0.05).Conclusions: Intravenous magnesium sulphate was more effective as compared to intrathecal route with regards to the pain scores and in providing postoperative analgesia.

Abstract Background Postoperative analgesia can be provided by a multimodal approach includes opioids, nonsteroidal anti-inflammatory drugs, paracetamol infusion and regional anesthetic techniques such as local infiltration or nerve blocks. In contrast to opioids, local anesthetics can be administered safely and in recent guidelines regional anesthesia is accepted as the cornerstone of postoperative pain relief in the pediatric patients. Objective Compare the postoperative analgesic effectiveness of local wound infiltration of bupivacaine against bupivacaine administered caudally in pediatric patients undergoing unilateral inguinal hernia repair. Patients and methods This study was carried out in Ain Shams University hospitals on 40 pediatric patients of both sexes aged from 6 months to 7 years belonging to ASA I or II undergoing elective unilateral inguinal hernia repair. They were randomly allocated into two groups: group C receiving caudal block, group L receiving local wound infiltration. Hemodynamic changes, postoperative pain score using FLACC pain score, postoperative analgesia and complications were recorded. Results There was no significant difference between the two groups as regard demographic data or hemodynamic variables. Pain score shows no statically significant differences between two groups in the first hour. But statistically significant decrease in FLACC score after (1, 2 and 3 hours) in group C in comparison with group L.decreased significantly in group C after 1 hour postoperative. Duration of analgesia longer in group C with no significant difference in total amount of postoperative analgesia. There was significant increase in incidence in complications in group C than group L Conclusion Caudal block provides better and longer analgesia but requires experience and may lead to complications. In contrast, wound infiltration is simple without significant side effects. Therefore, local wound infiltration may be a preferred technique for producing postoperative analgesia in pediatric inguinal hernia repair.
