Effectiveness of Intratracheal 2% Lidocaine Administration to Prevent Post Extubation Phenomenon in Tonsillectomy Surgery in the Central Surgical Installation of Kertha Usada Buleleng Hospital

Introduction: Post-extubation bleeding often occurs, especially in patients who experience coughing or other post-extubation phenomena. In addition, insufficient analgesia, especially in children who frequently cry or scream during the procedur, can cause tonsillar bed rebleeding. In this case report we attempted to use intratracheal 2 % lidocaine prior to extubation in a patient who underwent tonsillectomy under general anesthesia. Case Report: A 9 year old man who’s weighing 30 kg with chronic tonsillitis underwent a tonsillectomy under general anesthesia. Anesthetic impression: 9 year old boy suffering from chronic tonsillitis with ASA I. Approximately 10 minutes before the end of the surgery and after the tonsil was removed, 2mg/kg of intratracheal 2 % lidocaine was administered and the anesthesia was deepened to facilitate airway clearance and evaluate bleeding. Extubation is then carried out using the Smooth Emergence Techniques approach. Patient was positioned perfectly, he looked calm, complained of slight discomfort in the throat, did not experience coughing or vomiting, and there was no sign of tonsillar bleeding. Conclusion: in this case report, intratracheal administration of 2mg/kg 2 % lidocaine 10 minutes before extubation prevented the incidence of cough and other post-extubation phenomena during tonsillectomy surgery.
