The investigators compared the effects of remifentanil and dexmedetomidine administered under general anesthesia on hemodynamics, postoperative pain, recovery, postoperative nausea, vomiting, shivering, patient's and surgeon's satisfaction in patients undergoing elective rhinoplasty. A single-center, prospective, blinded, randomized controlled trial. After the approval of the hospital ethics committee (KA22/12), fifty volunteers aged 18-65 years who underwent rhinoplasty under elective conditions accepted the study in the American Society of Anesthesiologists (ASA) I-III class. The patients were randomly divided into the remifentanil group (group R) and the dexmedetomidine group (group D). Group R (n=25) was initially to receive remifentanil 0.01-0.2 g/kg/min without intraoperative loading. Group D (n=25) dexmedetomidine, was initiated with a bolus of 1 mg/kg and received 0.2-0.7 g/kg per hour as an infusion during surgery.

Remifentanil is an opioid; it has sedative, analgesic, and sympatholytic properties.
Studies show that dexmedetomidine is superior to currently commonly used remifentanil in terms of intraoperative blood pressure control and postoperative pain. Dexmedetomidine, an alpha-2-adrenoceptor agonist, has sympatholytic, sedative, anesthetic, analgesic, and vasoconstrictor effects. It lowers blood pressure by decreasing plasma norepinephrine and epinephrine levels, thereby reducing intraoperative bleeding. Dexmedetomidine is defined as an analgesic that is now widely used to induce and maintain anesthesia and to control postoperative pain, and is defined as an analgesic that does not cause respiratory depression and neurocognitive impairment. Many studies have shown that the use of perioperative dexmedetomidine reduces the stress response to anesthetic induction and surgery and provides hemodynamic stability.

Mean arterial pressure
The investigators compare the stability of mean arterial pressure.
Time frame: During surgery
Postoperative pain
The investigators compare the effect of remifentanil and dexmedetomidine on postoperative pain. The patients pain level was assessed using the numeric pain scale (Between 0-10, 0 = no pain, 10 = worst pain).
Time frame: Up to 30 minutes after the patient wakes up.
Patient Recovery Time
The investigators compare the effect of remifentanil and dexmedetomidine on patient recovery time. The recovery time of the patient will be evaluated by calculating the time between extubated and discharged from the postoperative care unit.
Time frame: Postoperative 1. hours
Postoperative nausea and vomiting scores
The investigators compare the effect of remifentanil and dexmedetomidine on nausea and vomiting. The presence of PONV was assessed using the Verbal Descriptor Scale (Between 0-3, 0=no nausea, 1=mild, 2=moderate, 3=severe).
Time frame: postoperative first 6 hours and 24 hours
Patient satisfaction
The investigators will question patients' degree of postoperative satisfaction. The patient satisfaction scale was used to assess the surgical outcome (Between 1 - 5, 1 = very poor, 5 = very good).
Time frame: Postoperative 6. hours
Surgeon satisfaction
The investigators will question surgeons' degree of satisfaction. The surgical satisfaction scale was used to assess the surgical outcome (Between 1 - 5, 1 = very poor, 5 = excellent).
Time frame: Postoperative 0. hours
