NCT ID NCT07328893
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a single dose of magnesium sulfate given during gallbladder surgery can lower the amount of morphine patients need afterward. 106 adults having laparoscopic gallbladder removal will be randomly assigned to receive either magnesium or a placebo. The goal is to see if magnesium reduces pain and the need for strong painkillers.
