Comparison of different types of laryngoscope(which are used to secure airway and anaesthetise patient)and to know physical and mental activity of anaesthesiq provider whipe doing so in a manikin based study, mimicking difficult airway scenario.

Comparison of Macintosh laryngoscope,C-MAC and King Vision channeled blade with respect to upper limb muscular activity and perceived workload using surface electromyography (SEMG) during orotracheal intubation in a manikin with simulated difficult airway, a prospective randomised cross over trial.

Design outcomes

Primary

MeasureTime frame
Comapre 3 laryngoscopes (Macintosh,C-MAC ,King Vision channeled blade ) with respect to muscle activity and workload of the anesthesiologists using surface electromyography ,on manikin with both normal and difficult airway scenario.Timepoint: After completing intubation ,that is after 60 seconds, using each laryngoscopes in different airway scenarios—

Secondary

MeasureTime frame
Compare 1st attempt success rate for all intubationTimepoint: After completing procedure;Compare maximum heart rate of anaesthesiologist during intubation in both normal and difficult airway with 3 laryngoscopesTimepoint: During intubation;Compare operators mental fatigue during intubation by NASA TLX score in both normal and difficult airway scenario using all the laryngoscopeTimepoint: After completing intubation;Compare time of intubation in normal and difficult airway with 3 laryngoscopesTimepoint: After completion of intubation;To assess failed intubation with 3 laryngoscopes in normal and difficult airway with 3 laryngoscopesTimepoint: After completing intubation;To compare force applied during intubation in both normal and difficult airway with 3 laryngoscopesTimepoint: After completing intubation—
