Hyo-Seok Na, Seoul National University Bundang Hospital
  Purpose
Arterial and venous thrombotic events are the clinical manifestation of postoperative hypercoagulability. Altered serum magnesium may play a role in the balance of coagulation. In this study, the investigators investigated the effect of magnesium sulphate on the postoperative coagulation change in total intravenous anesthesia (TIVA).

Condition Intervention
Myoma Drug: Magnesium Sulfate Drug: normal saline

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Effect of Magnesium Sulphate on Postoperative Coagulation as Measured by Thromboelastography
