【 摘 要 】

Background: Laryngoscopy and intubation is known to produce an exaggerated stress response. The aim in general anesthesia is to attenuate this stress response.Materials and Methods: This was a prospective, randomized, and a single blinded study. Ethical committee approval was obtained and 100 patients, aged 20-50 years, ASA grade I and II of either gender undergoing elective surgery under general anesthesia at a tertiary care center in India between 2015 and 2016 were recruited. We compared the Macintosh and McCoy laryngoscope blades regarding intubation time, laryngoscopic view and hemodynamic variables.Results: Both groups were comparable regarding age, gender, height and baseline vitals. Patients intubated with McCoy blade showed no or minimal change in heart rate and mean arterial pressure as compared to Macintosh blade. The intubation time was comparable in both groups.Conclusion: McCoy blade was better in attenuating the stress response to laryngoscopy and tracheal intubation.
