Özet
Aim: To examine the systemic and local effects of the lidocaine on the larynx and trachea which is applied after the end of the surgery and through various application methods. Study Design: Randomized controlled prospective study. Method: The study is composed of patients who underwent suspension laryngoscopy (SL) for benign laryngeal diseases (cysts, polyp, granuloma, etc) and American Society of Anesthesiologists (ASA) I, between January 2017 and January 2018. The patients were randomly divided into 3 groups. In the first group nothing is applied at the end of the surgery and called as control group, second group received 7 pufs of aerosolized 10% lidocaine solution (70 mg) over larynx and trachea and third group received cotton swaps that impregnated in 1 ml of 20 mg lidocaine solution over surgical area for 1 minutes. Operation and arousal times, heart rate and mean arterial blood pressure levels were noted and compared. Also laryngospasm, cough, and agitation scores were obtained during arousal. Results: 64 patients were included in the study. Laryngospasm was not observed in any of the patients. In group 2 (aerosolized lidocaine group), patients' blood pressure remained similar while increased in other groups (P < 0.05). Agitation scores were significantly lower in group 2 compared to the other groups (P = 0.012). Cough reflex is observed less in group 2 but result was not statistically significant (P = 0.13) Conclusion: The usage of aerosolized lidocaine after suspension laryngoscopy is very effective in blocking the stimulation of superior laryngeal nerve and sympathetic nerves which were responsible for the pressor reflexes. The inhibition of these reflexes before or during arousal could secure a safer arousal.
