Simulated Comparison of Standard Versus Rotational Laryngeal Mask Airway Insertion in Novice Anaesthesiologists.

Not Applicable

Completed

• Conditions: Training Group, Sensitivity
• Interventions: Device: LMA insertion with standard technique

• Registration Number: NCT05544838
• Lead Sponsor: Aga Khan University

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.

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)

Arm && Interventions

Group	Intervention	Description
Rotational LMA insertion technique	LMA insertion with standard 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.

Primary Outcome Measures

Name	Time	Method
The ease of LMA insertion was measured on the basis of number of LMA insertion attempts.	5 minute	Ease of LMA insertion in mannequin mouth was measured by performing the 10 times insertion of LMA with both study techniques in mannequin mouth by trainees.
The ease of LMA insertion was measured on the basis of final LMA insertion time taken duration.	5 minutes	The total time duration of final LMA insertion confirmation in mannequin mouth was recorded. The time duration counting was started from LMA holding in operator's hand to the confirmed successful insertion in mannequin mouth.

Secondary Outcome Measures

Name	Time	Method
The trainee's baseline knowledge was assessed for the type LMA insertion techniques.	1 minute	The trainee's baseline knowledge was assessed for the type LMA insertion techniques.
The trainee's baseline knowledge was assessed for the general or specific work experience in airway management using the LMA.	1 minute	The questionnaire based trainee's asked for previous experience in using the LMA device.
The trainee's baseline knowledge was assessed for the studied Rotational LMA insertion technique.	2 minutes	The questionnaire based trainee's asked for the previous experience for rotational LMA insertion technique.
The trainee's baseline knowledge was assessed for the type of supraglottic airway devices and LMA insertion techniques.	1 minute	The questionnaire based trainee's asked for the prior information of the LMA and other supraglottic airway devices.
