Accepts healthy volunteers: yes
Allocation: RANDOMIZED
Intervention model: CROSSOVER
Intervention model description: Each novice resident will place ten times LMA insertion with each insertion technique in randomised cross over manner by dividing the residents in two groups (5 residents in each group), by draw method. The one group will place LMA with standard insertion technique and other group will place by rotational LMA insertion technique, then after, the groups will switch over with concerned insertion techniques
Primary purpose: PREVENTION

Brief summary: The primary objective of study was to compare insertion ease by standard and rotational LMA insertion technique on basis of LMA insertion attempts and insertion time duration. The secondary objective of study was to analyse impact of prior information for airway device, insertion techniques, general or specific work experience in airway management with ease of both insertion techniques. And, tertiary objective of study was to analyse the trainee's preference insertion technique on basis of learning method and practical adaptability.

Hypothesis:

The rotational LMA insertion technique is easy to understand and practice than the standard LMA insertion technique at the beginning of airway management training among the novice anesthesiologists.

Hypothesis:

The rotational LMA insertion technique is easy to understand and practice than the standard LMA insertion technique at the beginning of airway management training among the novice anesthesiologists.

Detailed description: * LMA insertion attempts are the number of LMA insertion attempts with each study's insertion technique. The 10 insertion attempts will be performed with each insertion technique by trainees.
* LMA insertion time duration is the time taken to complete LMA insertion; from the holding of device till the confirmation of chest movement (artificial lungs inflation in manikin).
* The correlation of previous information for airway device, insertion techniques, general or specific work experience in airway management with the ease of both study's insertion techniques will be asked by participant's through the questionnaire at the start of study.
* The trainees will be asked at the end of study for preferred insertion method at novice level on the basis of learning method and practical conduct (user friendly)

Eligibility criteria: Inclusion Criteria:

* First year anaesthesia trainee
* Using adult mannequin

Exclusion Criteria:

* Paediatric mannequin
* Participant's refusal
