Direct laryngoscopy and endotracheal intubation procedure stimulate the sympathetic nervous system, causing catecholamine release into the circulation and consequently hemodynamic changes.There are many studies showing that lidocaine is used intravenously to suppress the sympathetic response to laryngoscopy and endotracheal intubation. Nebulized lidocaine is often used to provide upper airway local anesthesia in fiberoptic guided awake intubation. In this study, the researchers aimed to compare the results of using intravenous lidocaine and nebulized lidocaine to suppress the hemodynamic response caused by laryngoscopy and endotracheal intubation retrospectively. Researchers' hypothesis; Nebulized lidocaine administration is more effective than intravenous lidocaine administration in suppressing the hemodynamic response due to laryngoscopy and endotracheal intubation in patients under general anesthesia.
2% lidocaine drug to suppress the hemodynamic response due to laryngoscopy and endotracheal intubation; patients administered intravenously will be evaluated in one group, and patients administered inhaled through a nebulizer will be evaluated in another group. Nebulized lidocaine in the researchers' clinic; it is administered by adding 2% lidocaine + physiological saline to a nebulizer and inhaling for 3-5 minutes in the presence of 4-6 liters/minute of oxygen. Preoperative examination forms and intraoperative follow-up forms of the patients included in the study will be examined by the researchers. The dose of lidocaine applied and the method of administration will be recorded. In addition, the agents used in anesthesia induction (fentanyl, propofol, rocuronium bromide, etc.) and the hemodynamic changes of the patients (heart rate, systolic blood pressure, diastolic blood pressure, mean arterial pressure,oxygen saturation) will be recorded.

Time frame: 5 minutes and 10 minutes after direct laryngoscopy and endotracheal intubation
Blood Pressure
The patients were monitored in the operating room by wearing a noninvasive blood pressure cuff and measurements were taken at 5-minute intervals. Systolic blood pressure, diastolic blood pressure and mean arterial pressure were recorded in mmHg.
