Abstract
BACKGROUND: Airway management is the fundamental aspect of anaesthetic practice. The leading cause of anaesthetic morbidity and mortality are mainly the complications from difficult or failed intubation. The video laryngoscopes have been developed with the aim of reducing such complications. AIM OF THE STUDY: A Randomised Comparative Study of King vision Laryngoscopy, Truview EVO2 Laryngoscopy And Macintosh Laryngoscopy in routine airway management. METHODS AND METHODOLOGY: Three hundred patients between the age group 18-60 of ASA PS I and II undergoing elective surgeries under general anaesthesia with endotracheal intubation were randomized after ethical committee approval and informed consent into three groups(100 in each group) Group ML (Macintosh laryngoscope), Group KVL (Kingvision video laryngoscope) and Group TVL (Truview EVO2 laryngoscope). Patients (MPC I and II) were intubated with assigned laryngoscope and following parameters were analysed. The primary outcomes analysed were ease of intubation grade, intubation difficulty score (IDS) and Cormack Lehane grade, and secondary outcomes were time taken for intubation(TTI), POGO score and successful placement of endotracheal tube. The statistical analysis was done using statistical software package SPSS 16.0, with a P< 0.05 considered statistically significant. RESULTS: Cormack Lehane grading was grade I and II in both groups TVL and KVL and none grade III or IV. CL grade I in 53% in TVL group, 55% in KVL group, and CL grade I in 34 % and grade III 2% and none grade 4 in ML( p >0.05). IDS was lower with TVL group compared to ML and KVL.TTI was longer in TVL (27.92 sec) and KVL (27.87 sec) than with ML(24.21 sec), p <0.05 statistically significant. Ease of intubation grade was significant and better with group TVL. POGO score ML(84.5%),TVL(86.2%), and KVL(84.9%) was significant. Success rate of intubation was 97 % in TVL and 96 % in KVL group. CONCLUSION: Truview and Kingvision laryngoscopes had better laryngeal view in terms of CL grading and POGO scores, though time taken for intubation was prolonged with both when compared with Macintosh laryngoscope. Hence, I conclude that both the video laryngoscopes are superior to Macintosh laryngoscope in terms of laryngeal view and are recommended for routine airway management.
