Summary

Post-operative pain management is a complex entity. It is one of the most critical parameters in the enhanced recovery after surgery protocol. Adequate postoperative pain relief leads to earlier mobilisation, shortened hospital stay, reduced hospital costs and increased patient satisfaction.

For post-operative analgesia, opioids have long been the mainstay of drugs used; however, they produce unwanted side effects, such as respiratory depression, nausea, vomiting and dependence. The major goal in postoperative pain management is to minimise the dose of a single medication and lessen its side effects, while still providing adequate analgesia by the use of multimodal analgesia. Paracetamol, non-steroidal anti-inflammatory drugs (NSAIDs), regional techniques like epidural analgesia, different kind of blocks and local wound infiltration are some of the components of multimodal approach to post- operative analgesia.

Besides, there are some drugs that may be used as adjuvants to opioids to enhance the analgesic efficacy and facilitate opioid sparing with a reduction in opioid related side effects. Magnesium sulphate, due to its N- Methyl D- Aspartate (NMDA) blocking property, has been studied as one of such non opioid adjuvants. The outcome of many of these studies is in favour of magnesium sulphate but there are negative reports as well.

So, in this study the investigators aim to evaluate the efficacy of intra-operative intravenous magnesium sulphate for post-operative pain and opioid use in patients undergoing abdominal hysterectomy under general anaesthesia.
