Evaluation of King's vision videolaryngoscope and glidescope on hemodynamic stress response to laryngoscopy and endotracheal intubation

Abstract

Background and Aims: We hypothesis that the use of novel airway devices would decrease hemodynamic stress response (HDSR) to laryngoscopy and endotracheal (ET) intubation. The aim of our study was to evaluate the hemodynamic stress response (HDSR) to laryngoscopy and tracheal intubation using the King vision video laryngoscope (KVVL) versus glidescope (GLS). Material and Methods: A prospective randomized, comparative study that was conducted on 80 patients of both sexes; American Society of Anesthesiologists physical status I and II with no anticipated difficult airway, aged 20–60 years; who were scheduled for elective surgical procedure under general anesthesia. Patients were randomly allocated into two groups (40 each). Group I: laryngoscopy and tracheal intubation were carried out using KVVL, Group II: laryngoscopy and tracheal intubation were carried out using GLS. The two groups were compared for noninvasive hemodynamic data such as heart rate and mean arterial pressure. Time to successful intubation and number of attempts were recorded. Hemodynamic parameters were recorded at the preinduction, after induction, at intubation, 1 min, 3 min, 5 min, 10 min, and 15 min. Results: There was significant decrease ( P < 0.05) in HR and MBP in both groups just before intubation. In comparison with the baseline, HR and MBP in group I and group II increased but this difference was not significant at 3 min and 5 min after intubation and returned to the baseline at 10 min after intubation and below the baseline at 15 min after intubation. Also, there were no significant differences in the hemodynamic response between the studied groups. Conclusion: Novel airway devices either KVVL or GLS are efficient in reducing HDSR to laryngoscopy and ET intubation.

Comparison of Intravenous Tramadol vs Intravenous Morphine in Attenuation of Hemodynamic Stress response to Laryngoscopy and Endotracheal Intubation in Laparoscopic Cholecystectomy

“…Using a king video laryngoscope or a glide scope, hemodynamic alteration after laryngoscopy and intubation were studied, and both were found effective in attenuating the stress response. 15 In a similar study, a single-time use video laryngoscope was compared with a Macintosh laryngoscope as in our study. The hemodynamic stability following laryngoscopy and endotracheal intubation was more pronounced when AirTran was used than Macintosh.…”

Effects of Sevoflurane Laryngeal Mask Inhalation Combined with Intravenous Anesthesia on Perioperative Stress and Myocardial Injury in Elderly Patients with Acute Cholecystitis and Coronary Heart Disease

“…Traditional anesthesia requires endotracheal intubation, and there are many receptors in the throat. Direct endotracheal intubation can cause intense stimulation, leading to arousal of sympathetic nervous system and aggravation of cardiovascular stress response, which may aggravate coronary heart disease in patients [ 12 ]. The results of this study found that, at T1-T4, the levels of MAP and HR in the two groups first decreased and then increased, and the observation group was higher than the control group.…”
