Ketamine Versus Magnesium Sulfate in the Time and Awakening Quality of General Anesthesia.

About This Study

The introduction of the laparoscopic technique for cholecystectomy significantly reduced the incidence and intensity of postoperative pain, with improvement in other markers, such as patient satisfaction, and reduction in hospital stay. However, pain in the postoperative period of laparoscopic cholecystectomy is still a concern that challenges modern anesthesiology. Ketamine and magnesium sulfate are two blockers of N-methyl-D-aspartate (NMDA) receptors with the ability to reduce postoperative pain and postoperative opioid consumption. A frequent concern among anesthesiologists is the quality and time of awakening in patients receiving these medications The main objective of this trial is to compare the quality and time of awakening in patients receiving magnesium sulfate or ketamine. The secondary objective is to compare postoperative analgesia during the postoperative hospital stay. Hypothesis: Our hypothesis is that patients have a faster awakening when they receive magnesium sulfate as an analgesic adjunct, when compared to patients who receive ketamine . Design: this is a prospective, controlled, covered and randomly distributed trial.
