“A COMPARATIVE STUDY OF HEMODYNAMIC RESPONSE FOLLOWING LARYNGOSCOPY AND ENDOTRACHEAL INTUBATION: DIRECT VERSUS VIDEO LARYNGOSCOPY”

Abstract

Introduction: Laryngoscopy and endotracheal intubation are the two essential procedures when general anaesthesia is administered to a patient. Adverse responses in the cardiovascular, respiratory, and other physiological systems can be provoked due to the noxious stimuli produced by laryngoscopy and intubation.1 During general anaesthesia maintenance of airway and ventilation can be done in various ways. Aims & Objectives: To assess the superiority of video laryngoscopy over direct laryngoscopy using baseline parameters like heart rate, systolic blood pressure, diastolic blood pressure and mean blood pressure. Materials And Methods: Interventional, Randomized study. Operation theatre of Durgapur Steel Plant Hospital, Durgapur, West Bengal. Adult males and females, ASA physical Grade 1 and 2 patients, scheduled for elective surgeries, under General Anesthesia, requiring or tracheal intubation. 1 year. From February 2018 to February 2019. Result And Analysis:In Group-A (MDL), 28(56.0%) patients had MPG 1 and 22(44.0%) patients had MPG 2. In Group-B (KVVL), 29(58.0%) patients had MPG 1 and 21(42.0%) patients had MPG 2. Association of MPG vs. group was not statistically signicant (p=0.8399). In Group-A (MDL), the mean time taken for intubation (mean±s.d.) of patients was 34.5600 ± 2.3661. In Group-B (KVVL), the mean time taken for intubation (mean±s.d.) of patients was 20.4000 ± 1.7728. Distribution of mean time taken for intubation vs. group was statistically signicant (p<0.0001). Conclusion: Also, Kingvision video laryngoscope offered less intubation time and reduced hemodynamic responses in patients with ASA grade 1and 2 as compared to Macintosh laryngoscope. So further study can be done on patients with difcult airways (III-IV) and with different co morbidities (ASA 3,4, E) to evaluate whether using Kingvision video laryngoscope can be advantageous in reducing intubation time and obtunding hemodynamic responses to laryngoscopy and intubation.
