Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

* 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)

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

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

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

LMA with standard insertion technique

Standard LMA insertion technique; LMA held like a pen and index finger placed at the junction of LMA tube and cuff. Index finger used to press LMA against hard palate and posterior pharyngeal wall until definite resistance felt at the base of hypopharynx. LMA then held with non- dominant hand and index finger removed.

Group Type NO_INTERVENTION

No interventions assigned to this group

Rotational LMA insertion technique

Rotational LMA insertion; LMA inserted like guedel airway insertion: LMA proximally grasped close to anaesthesia circuit attachment. Insertion was conducted with LMA cuff facing towards nose, hard palate and then advanced into the base of hypopharynx until resistance was felt. At this point, LMA rotated at 180 degree anti-clockwise and LMA tube black line positioned and confirmed on the nasal side.
