A Comparison of Kings Vision Video Laryngoscope with Macintosh Laryngoscope in Adult Patients Undergoing Elective Surgical Procedure

Airway management remains a vital primary skill for anaesthesiologist. We aimed at comparing the efficacy of direct laryngoscopy using the conventional Macintosh blade with indirect laryngoscopy using the King Vision video laryngoscope (KVVL) with regard to visualization of the laryngeal view, speed of intubation, intubation success rate, complications and hemodynamic stability. After approval from hospital ethical committee this study was carried out in 50 patients of American Society of Anesthesiologist (ASA) physical status I& II, aged 20 to 60 years of either sex, scheduled for elective surgeries under general anaesthesia. All patients were divided in to two groups. Group K patients were intubated using King vision laryngoscope and in Group M - patients were intubated using Macintosh laryngoscope. Kings vision video laryngoscope with channeled blade performed better during intubation as compared to Macintosh laryngoscope in terms of better visualization of glottis, lesser attempts for intubation, lesser airway trauma& reduced hemodynamic response to laryngoscopy.
