SORE THROAT
This study employed a single-blinded approach, where the anesthetist was aware of the medication administered, while the patients remained unaware. The study included a total of 100 patients, who were randomly assigned to four equal groups with 25 patients each:
Control group: No medication applied to the endotracheal tube (C)Glycerin emollient lubricated tubes group: Application of glycerin emollient to the endotracheal tube (G)Lidocaine gel lubricated tubes group: Application of lidocaine gel to the endotracheal tube (L)Dexamethasone emollient lubricated tubes group: Application of dexamethasone emollient to the endotracheal tube (D)Two milliliters of the respective emollient or gel were used to sufficiently lubricate the endotracheal tube from the distal tip to a length of 15cm. A measuring cup was employed for accurate measurement. The drug concentrations used were 5% lidocaine and 0.3% dexamethasone. An endotracheal tube with a 7 mm internal diameter was used for female patients, while for male patients, a tube with a 7.5 mm internal diameter was utilized. The high-volume low-pressure cuff was inflated to the minimum pressure required to prevent audible air leaks and ensure proper ventilation, following the principle of minimal occlusive volume. In the postoperative care unit, patients received standard care, which involved close observation, administration of oxygen via a face mask, monitoring of oxygen saturation (Spo2), pulse rate, and non-invasive blood pressure measurements (NIBPM). Additionally, patients in the general ward were administered intravenous paracetamol (1g * 3). After 24 hours of the postoperative period, patients were assessed in the ward regarding hoarseness of voice and sore throat at any time during the last 24 hours after the operation.
