NCT04603638

Brief Summary

In this study ; Two randomized groups will be created. Iv magnesium will be given to one of the blindly designated groups. The other group will be given only isotonic. All patients will be awakened after the analgesic agents (0,1mg / kg morphine, 15mg / kg paracetamol, nsaid) are used in routine practice and will be followed up for intensive care. The use of PCA (patient controlled analgesia) device is available in both groups.In post-operative period, magnesium infusion will be continued for 12 h. Only 100cc isotonic will be given without using magnesium to the other group. VAS (visual analog scale) score will be recorded at postoperative 30. minutes and 2,6,12,18,24 hours. In routine administration, the patient should be given 2 mg of morphine if vas\>4 and the maximum dose will be increased to 10 mg.
