comparison of the analgesic effect of paracetamol and magnesium sulfate during surgeries

background new drugs are increasingly used to induce analgesia during surgeries. this study compared the analgesic effects of paracetamol and magnesium sulfate. methods sixty patients with american society of anesthesiologists (asa) class i or ii patients who were candidates for surgery of the lower limbs were randomly divided into three equal groups who were age and gender matched. group 1 received paracetamol, and group 2, the magnesium sulfate during surgery and group 3 as the control. pain intensities were measured and recorded using the visual analog scale before surgery, in the recovery room, and 6, 12, and 18 hours after surgery. results pain intensities (7.10, 5.80, and 4.10) were higher in the control group; 6, 12, and 18 hours after surgery compared to the paracetamol (6.45, 4.15, 2.50) and the magnesium groups (7.25, 4.55, and 2.05), but the difference was not statistically significant. conclusion paracetamol and magnesium sulfate were shown to have postoperative analgesic effects and reduce the quantity of narcotic use after surgery.
