      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: In this randomized controlled clinical trial, the patients will be consecutively and in a 1:1 ratio assigned into two groups based on a simple randomization method. The surgeon is informed about the assigned group for each person by a sealed letter, Blinding description: In this double-blind study, patients are evaluated with random ID numbers assigned to them by the researcher. Patients and the data collector will be blind. Patients are kept unaware of their group assignment and the intervention they are receiving. Both the treatment and control groups receive identical instructions and support. The data collector is kept blind to the group assignment of each patient and will record the results only according to the patient IDs.</study_design>

      <i_freetext>Intervention 1: Intervention group: The patients in the intervention group will receive the first ascorbic acid dose (1 g in 10 mL) at the beginning of the surgery. Another dose of ascorbic acid (1 g in 10 mL) will be infused during the surgery. After the surgery, an additional dose of ascorbic acid (1 g in 10mL) will be infused postoperatively during the first 12h. Intervention 2: Control group: The patients in the control group will receive only normal saline.</i_freetext>
