To Measure Systolic Blood Pressure Postintubation Clinical Trial
Official title:
Evaluating the Effect of Topical Lidocaine Spray Versus Dexmedetomidine Spray on Suppression of Stress Response to Laryngoscopy and Endotracheal Intubation: a Randomized Controlled Study
Many studies discussed attenuating stress response by various measures but to the interest of our study , No one compared topical spray of both lidocaine and dexmedetomidine in attenuating the haemodynamic stress responses of laryngoscopy and endotracheal intubation, avoiding undesired systemic effects of drugs ,
This study will be conducted in the operating theatres of Cairo university hospitals. Patients undergoing any surgery under general anesthesia and needs endotracheal intubation using direct laryngoscopy will be assigned to one of the three groups: Group C: will receive 5ml of normal saline sprayed via long nostril syringe into oropharynx, the vocal cords and tracheobronchial tree 5 minutes before intubation Group L: : will receive 5ml of lidocaine 2% (100mg) sprayed via long nostril syringe into oropharynx , the vocal cords and tracheobronchial tree 5 minutes before intubation Group D: : will receive dexmedetomidine (1 μg/kg) diluted in 5ml normal saline sprayed via long nostril syringe into oropharynx , the vocal cords and tracheobronchial tree 5 minutes before intubation. ;
