Comparison of effectiveness of mask ventilation by Consultant Anesthesiologist and Resident Anesthesiology Postgraduate with and without using Airway Adjuncts: A Prospective Study

Maskventilation is an important management skill. Creating a seal between the maskand the patient’s face by lifting the mandible (chin lift) and providing jawthrust allows for positive pressure (assisted) ventilation.  Mask ventilation may be required to assistwith ventilation before intubation to achieve preoxygenation. Thus ifintubation proves to be difficult after induction , mask ventilation canprovide critical oxygenation and ventilation between laryngoscopy attempts.

Kogaet al in his study compares between a cuffed oropharyngeal airway adjunct and aGuedel Airway with the final conclusion that an oropharyngeal airway plays abetter role in opening the airways to pre-oxygenate a patient duringventillation.Similiarly in our study we will be comparing an oropharyngealairway device with that of a nasopharyngeal airway device to see which is moreefficacious in opening the airways of a patient under general anaesthesia andassist in breathing. Langeron et al stresses on how the use of airway adjunctsas those used in the proposed study above help to ventilate patients withsuspected difficult airway. Alexander et al on the other hand compares the easeof insertion of the airways based on training and experience.

Thisstudy will also shed some light on the learning curve of a resident(postgraduate) anaestheesiologist with minimum 6 months experience in theteaching curriculum
