研究概览
简要总结
It is a prospective randomised comparative study to compare the changes in perfusion index to endotracheal intubation either with Macintosh, McCoy or video laryngoscope in patients undergoing elective surgery under general anaesthesia. Here patients will be allocated into three groups by block randomisation. Patients of a particular group will be undergoing laryngoscopy and intubation by using a particular type of laryngoscope. Changes in Perfusion index and hemodynamic variables will be noted at baseline, just before induction, immediately before laryngoscopy, immediately after laryngoscopy and intubation, and 2,4,6,8,10 minutes after intubation. Correlation between perfusion index and haemodynamic variables will be investigated. The study will evaluate which among the laryngoscopes will show better perfusion index and lesser haemodynamic response.
