After the approval of the ethics committee for the study, in the Istanbul University Faculty of Medicine Orthopedics and Traumatology Department; There will be 3 or more posterior instrumentation operations, cobb angle of 40 degrees and above, 18-75 years old, ASA (American Society of Anesthesiologists) score 1-3, no chronic neuropathic pain and no psychiatric illness, no chronic narcotic analgesics and / or substance abuse a creatine value below 1.3 will be included.

Our clinic; PCA (patient-controlled analgesia) device with intravenous morphine is used routinely for postoperative analgesia.In this study ;two randomized groups will be created. It will give iv magnesium(in the intraoperative period at a dose of 40mg / kg, within 30 minutes after induction) to a blindly designated group. The other group will be given only isotonic. After in post-operative period, magnesium infusion will be continued for 12 hours (40mg / kg). Magnesium sulfate will be given in 100 cc isotonic. In the other group, only 100cc isotonic will be given without using magnesium. 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 device is available in both groups. vas score will be recorded postoperative 30. minutes and 2,6,12,18,24 hours.
