Aim and Background:

 

Safe airway maintenance in patients under general anesthesia is the most

important duty of anaesthesiologists. Classic laryngeal mask airway (CLMA) is a supra-glottic

device to achieve this aim. There are different insertion techniques for this device, but the best of

them is unknown.

Methods and Materials:

 

Two hundred patients were included in this mono-blinded clinical trial.

Patients were divided into four groups. The CLMA was inserted by the index finger in the

standard group, by 45 degree rotation into lateral position in the lateral technique group, by 180

degree rotation in the rotational technique, and finally in the modified standard group we used a

standard like method without using the index finger. We evaluated the number of insertion trials,

ease of insertion and the time needed for successful trial. Airway sealing pressure and post

operative complications were also assessed.

Findings:

 

With the lateral technique, CLMA was more easily inserted, and the time needed for

insertion was also significantly decreased. In the meanwhile, we encountered less blood stained

LMA with the lateral technique (p<0/05). The first-trial success rate was more in the lateraltechnique

group but the difference was not shown to be significant.

Conclusions:

 

Lateral insertion of CLMA increases ease and first-attempt success rate and at the

same time, it reduces insertion time and bleeding .As a result, this technique can be recommended

whenever LMA insertion is necessary in patients undergoing general anesthesia.
