RESUMEN
ABSTRACT:Background: Endotracheal intubation is gold standard of general anesthesia. various oral,Maxillofacial, Dental surgeries are carried out in high-risk patients having chances ofdifficult intubation. If we give sedation or general anesthesia, we can be trapped in criticalairway accidents.Aims & objectives: To access & compare efficacy of anatomical landmark guided/Ultrasound guided superior laryngeal nerve block associated with topical Anesthesia &transtracheal block for awake blind nasal intubation.Method:Group A: Anatomical landmark guided superior laryngeal nerve block given(n=30)Group B: ultrasound guided superior laryngeal nerve block(n=30)In both groups topical Anesthesia & transtracheal block for awake blind nasal intubation wasgiven.Results: upper airway block provide clinical ease to facilitate blind nasal awake intubation.ultrasound guided block has less adverse reactions.Conclusion: Both methods provide good quality of Endotracheal intubation, but ultrasoundguided block is more efficient & scientific method to block superior laryngeal nerve forawake nasal intubation.
RESUMEN
Background: Endotracheal intubation is gold standard of general anaesthesia. But it hasdisadvantages of initiation of stress response to laryngoscopy and intubation. To alleviate itwe have used Dexmedetomidine & Esmolol.MethodsGroup E - Inj. Esmolol (1.0 mg/kg) in 10 ml normal saline two minutes before inductionGroup D – Inj. Dexmedetomidine (1μg/kg) in 10 ml normal saline over 10 minutes prior toinduction.Results and conclusion: both the drugs effectively supress stress response but Dexmedetomidine is better than Esmolol
