AN OBSERVATIONAL STUDY TO EVALUATE THE HAEMODYNAMIC CHANGES\nBETWEEN ENDOTRACHEAL INTUBATION AND LARYNGEAL MASK AIRWAY\nINSERTION

Abstract

Introduction: Airway management is a crucial skill for the clinical anaesthesiologist. It is an integral part of general anesthesia, allowing\nventilation and oxygenation as well as a mode for anesthetic gas delivery. The laryngeal mask airways (LMA) have become popular in airway\nmanagement as a missing link between facemask and tracheal tube in terms of both anatomical position and degree of invasiveness.\nHaemodynamic stability is an important aspect to the anaesthesiologist for the bene\uf001t of the patients especially during intubations, laryngeal mask\ninsertion. Laryngoscopy and endotracheal intubation can cause striking changes in Haemodynamics as result of intense stimulation of sympathetic\nnervous system. The aim of this study was to evaluate the hemodynamic changes between endotracheal intubation and laryngeal mask airway\ninsertion.\nMaterial And Methods: This was a prospective observational study on 46 patients of ASA I-II status divided into 2 groups of 23 each. In the ETT\n(Endotracheal tube) group endotracheal intubation was done using Macintosh laryngoscope by using portex cuffed endotracheal while in LMA\n(Laryngeal mask airway) group laryngeal mask airway was inserted according to the standard recommendation. Heart rate, Systolic, Diastolic and\nMean arterial pressure and dysrhythmias were monitored.\nResults: The two groups were comparable in terms of demographic data as there were no signi\uf001cant differences between the 2 groups in terms of\nage, sex, duration of surgery, ASA grades and MPC classi\uf001cation. Heart rate (HR), Systolic blood pressure (SBP), Diastolic blood pressure(DBP),\nMean arterial pressure (MAP) remains on higher side in ETT group than LMA group which was statistically signi\uf001cant. P<0.05. Dysrhythmias\nwere noted in 2 patients of ETT group while LMA group did not notice any dysrhythmias.\nConclusion: This study demonstrated that there is a haemodynamic response consisting of an increase in Heart rate, SBP, DBP and MAP that\ncomes with ETT insertion as well as with LMA insertion. However, the response caused by ETT insertion is signi\uf001cantly greater than that caused\nby LMA insertion.
