Magnesium Sulfate Versus Dexmedetomidine on Anesthesia Awakening.

Summary

Magnesium sulfate (MS) and dexmedetomidine have already demonstrated the ability to reduce intra and postoperative consumption of anesthetics and analgesics, among others advantages, such as blood pressure control and intraoperative bleeding. The MS has also been shown to be useful in pre-eclampsia and eclampsia control, pulmonary hypertension, asthma, cardiac arrhythmias and pheochromocytoma). Despite these advantages in the use of these important adjuncts, there is a concern about the quality and awakening time of the patients who use them. The purpose of this trial is to compare the time and quality of awakening in patients submitted to general anesthesia and receiving MS or dexmedetomidine as adjuncts in the intraoperative analgesia. The main objective of this trial is to compare the quality and the awakening time in patients receiving MS or dexmedetomidine. The secondary objective is the comparison of postoperative analgesia in the postoperative hospitalization period. Hypothesis: Our hypothesis is that patients present a faster awakening when receive MS as an analgesic adjunct, when compared to patients who receive dexmedetomidine. Drawing: this is a prospective, controlled, covert trial with random distribution for noninferiority trialing.
