Anesthesiology and pain medicine

Magnesium is an antagonist of (N-methyl D-Aspartate) NMDA receptor and its related canals, and may affect perceived pain. ⋯ Intravenous magnesium reduces postoperative ileus, postoperative severe pain and intra/post operative analgesic requirements in patients after major GI surgery. No side effects of magnesium in these doses were seen, so it seems to be beneficial along with routine general anesthesia in major GI surgeries.
