 We compared hemodynamic responses following laryngeal mask airway insertion versus tracheal intubation in hypertensive patients who were scheduled for elective ophthalmic surgery under general anesthesia. We studied 48 controlled hypertensive patients that were randomly divided into two groups (n=24) for insertion of laryngeal mask airway (LMA) and endotracheal intubation (EI). The mean arterial blood pressure (MAP), heart rate, rate pressure product (RPP), and ST-segment changes were recorded preoperatively, immediately preintubation and 1, 3, and 5 minutes after LMA insertion or tracheal intubation in all patients and compared between two groups. There was a reduction in MAP after induction and immediately preintubation in all of patients of both groups (P<0.05). The MAP, heart rate and RPP increased immediately after both LMA insertion and tracheal intubation (P<0.05). The elevation of MAP and RPP were maintained for longer time in intubation group versus LMA group (P<0.05). There was no difference between the groups with respect to ST-segment variation. The incidence of airway injury was similar between two groups. The laryngeal mask airway insertion may be preferable to endotracheal intubation in hypertensive patients where attenuation of hemodynamic stress response is desired. © 2019 Tehran University of Medical Sciences.

Laryngeal Mask Airway Insertion

Introduction: Airway management is a crucial skill for the clinical anaesthesiologist. It is an integral part of general anesthesia, allowing ventilation and oxygenation as well as a mode for anesthetic gas delivery. The laryngeal mask airways (LMA) have become popular in airway management as a missing link between facemask and tracheal tube in terms of both anatomical position and degree of invasiveness. Haemodynamic stability is an important aspect to the anaesthesiologist for the benet of the patients especially during intubations, laryngeal mask insertion. Laryngoscopy and endotracheal intubation can cause striking changes in Haemodynamics as result of intense stimulation of sympathetic nervous system. The aim of this study was to evaluate the hemodynamic changes between endotracheal intubation and laryngeal mask airway insertion. Material 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 (Endotracheal tube) group endotracheal intubation was done using Macintosh laryngoscope by using portex cuffed endotracheal while in LMA (Laryngeal mask airway) group laryngeal mask airway was inserted according to the standard recommendation. Heart rate, Systolic, Diastolic and Mean arterial pressure and dysrhythmias were monitored. Results: The two groups were comparable in terms of demographic data as there were no signicant differences between the 2 groups in terms of age, sex, duration of surgery, ASA grades and MPC classication. Heart rate (HR), Systolic blood pressure (SBP), Diastolic blood pressure(DBP), Mean arterial pressure (MAP) remains on higher side in ETT group than LMA group which was statistically signicant. P<0.05. Dysrhythmias were noted in 2 patients of ETT group while LMA group did not notice any dysrhythmias. Conclusion: This study demonstrated that there is a haemodynamic response consisting of an increase in Heart rate, SBP, DBP and MAP that comes with ETT insertion as well as with LMA insertion. However, the response caused by ETT insertion is signicantly greater than that caused by LMA insertion.

Background: Fibreoptic intubation and Intubating laryngeal mask airway are alternatives to conventional laryngoscopy. The objective of the study was to compare hemodynamic changes with the use of these two devices for tracheal intubation.Methods: It was a randomized, comparative and prospective study of two groups comprising of 50 patients each. Tracheal intubations were performed using intubating fiberscope in group I and intubating laryngeal mask airway in Group II. Intubation time, heart rate, blood pressure and complications were compared.Results: Heart rate response to tracheal intubation was comparable between the groups. Changes in mean arterial pressure were also comparable and returned to baseline after two minutes of tracheal intubation. The first attempt success rate was 80% and 92% respectively in Group I and Group II. The time taken for intubation was found to be significantly longer in Group II irrespective of the number of attempts. There were no major complications observed. However there was some desaturation at the time of intubation which was seen in three patients in Group I, and one patient in Group II. However the Spo2 did not fall below 96% and was not considered to be clinically significant.Conclusions: Endotracheal intubation using either an Intubating Laryngeal Mask Airway or a Fibreoptic Bronchoscope is comparable in terms of the haemodynamic responses.Journal of Society of Anesthesiologists 2014 1(2): 70-75
