The Effect Of Preoperative Anxiety Level On Postoperative SoreThroat

Demographic data (age, gender, height, weight, body mass index (BMI) and ASA classification will be recorded preoperatively. The trait and state anxiety scale (STAI-T and STAI-S) will be administered at the preoperative visit. Standard anesthesia monitoring (electrocardiogram-ECG, noninvasive blood pressure-NIBP, pulse oximetry-SPO2, temperature, EtCO2- End Tidal Carbon Dioxide), neuromuscular monitoring (TOF) will be performed before anesthesia induction. These data will be recorded at 5 minute (min) intervals from the beginning to the end of the operation. A vascular access of appropriate width will be opened and 10 ml/kg balanced crystalloid fluid infusion will be started. Lidocaine 1 mg/kg, fentanyl 1 mg/kg, propofol 2-3 mg/kg and rocuronium 0.6 mg/kg will be administered intravenously (IV). Then, when the Train of four rate (TOFR) response is zero, orotracheal intubation will be performed with Macintosh bleyd 3 or 4 by selecting straight tubes with an inner diameter of 8.0-8.5 mm for male patients and 7-7.5 mm for female patients. (In case of neuromuscular blocker requirement, rocuronium 0.1 mg/kg IV will be administered additionally. Endotracheal tube (ETT) cuff pressure will be adjusted to 20-30 cmH2O with a cuff manometer. ETT cuff pressure will be measured at 20 minute intervals and recorded in the file. Anesthesia maintenance will be performed with 0.5 L/min fresh gas flow, oxygen concentration with inspiratory oxygen level between 40-45, sevoflurane with a minimum alveolar concentration (MAK) of 1.0. Mechanical ventilation will be performed with Volume-Auto Flow mode with EtCO₂ between 35-40 mmHg. Analgesia maintenance will be provided with remifentanil infusion (0.6-15 mcg/kg/hour). In case of (±) 15% change in the haemodynamic parameters of the patient compared to the baseline values, remifentanil infusion dose will be intervened by increasing and decreasing at the specified intervals and the amount consumed intraoperatively at the end of the operation will be recorded. Hypotension will be defined as hypotension when systolic arterial pressure decreases by 30% compared to baseline. In the treatment, 250 ml of 0.9% NaCl rapid infusion will be administered first. If no response is obtained, 10 mg ephedrine IV will be given. When bradycardia occurs (heart rate ≤50 beats/min), atropine 0.5 mg IV will be administered.

Paracetamol 10 mg/kg and tramadol 1 mg/kg will be administered before the operation is terminated. Fresh gas flow will be increased to 8 L/min at the end of the operation. Sugammadex 4 mg/kg will be administered IV to terminate neuromuscular blockade. When TOFR is 0.9, the patient will be extubated and transferred to the postoperative recovery unit (PACU). Patients with Aldrete score ≥ 9 will be transferred from PACU to the ward.

The time from skin incision until the end of the surgical procedure will be recorded as "Operation Time". The time between the termination of sevoflurane (Sevorane 100% inhalation solution) flow and extubation will be recorded as "Extubation Time", and the time between anesthesia induction and extubation will be recorded as "Anesthesia Time". The time between the patient's admission to the PACU and discharge to the ward will be recorded as "Recovery Time".

Postoperative complaints of sore throat, hoarseness, cough, nausea and vomiting will be recorded at 0, 2, 4 and 24 hours using numerical rating scales (NRS). At the and of the study patients will be evaluated according to STAI-I and divided into 2 groups. Group 1: Patients below 45 points - no anxiety. Group 2: Patients with scores above 45 - there is anxiety.

The intraoperative data and postoperative complication status of the volunteers will be followed up by an anesthetist who is not aware of the results of the anxiety rating scale and recorded in the file.

Numerical Rating Scale (NRS): Zero indicates no pain and ten points indicates unbearable pain.

All patients will be asked whether they have sore throat at 0, 2, 4, 12 and 24 hours postoperatively. Patients will be asked to give a score between 0-10 for sore throat.
