A Comparative Study of Cardiovascular Responses to Laryngoscopy Using McCoy, Macintosh and Miller Blades
Journal Title: International Journal of Medical Research Professionals - Year 2017, Vol 3, Issue 3
Abstract
Background: Laryngoscopy is a procedure that is used to obtain a view of the vocal folds and the glottis to facilitate tracheal intubation during general anaesthesia or cardiopulmonary resuscitation or for surgical procedures. Different types of curved and straight blades are used for laryngoscopy which affects the haemodynamic parameters. Methods: The prospective, comparative study was done in the department of anaesthesia for the period of six months with the aim to compare the haemodynamic response in the form of heart rate and mean arterial pressure after intubation with three different types of blades of laryngoscope (Mc Coy, Macintosh and Miller). The study was conducted on 75 patients of 20-50 years, of both genders, which were randomly selected and divided into three groups with 25 patients in each. During intubation McCoy (MC), Macintosh (MT) and Miller (ML) blades were used for intubation in group A, B and C respectively. Results: The haemodynamic stress response with the Macintosh laryngoscopy is more than that of McCoy and Miller laryngoscopy. The haemodynamic stress response (increased heart rate and mean arterial pressure) is least with Miller laryngoscopy. Conclusion: The haemodynamic response (increased heart rate and mean arterial pressure) to laryngoscopy is least with Miller laryngoscope and most with Macintosh laryngoscope.
