Steps for Using Laryngeal Mask Airway
1. Pre-use Inspection
Check packaging integrity and expiration date.
Select the correct LMA size based on the patient's weight and age.
2. Cuff Deflation & Lubrication
Fully deflate the cuff using a syringe.
Apply a thin layer of water-based lubricant to the posterior surface of the mask.
3. Patient Positioning
Place the patient in the “sniffing” position: head slightly extended, neck flexed.
Ensure airway alignment to facilitate insertion.
4. Insertion
Hold the LMA like a pen.
Insert with the tip pressing against the hard palate.
Advance along the oropharyngeal curve until resistance is felt at the hypopharynx.
5. Cuff Inflation
Inflate the cuff with the recommended air volume (refer to size chart).
Do not exceed the maximum cuff pressure (typically < 60 cmH₂O).
Confirm a good seal.
6. Ventilation Check
Connect to the breathing circuit or manual resuscitator.
Observe chest rise, listen for bilateral breath sounds, and confirm capnography waveform.
Ensure minimal leak during ventilation.
7. Device Securing
Secure the LMA in place using adhesive tape or a tube holder.
Prevent displacement during the procedure.
8. Intra-operative Monitoring
Continuously monitor oxygen saturation, airway pressure, and patient vital signs.
Maintain cuff pressure within safe limits.
9. Removal
At the end of anesthesia, deflate the cuff once the patient regains airway reflexes.
Gently remove the LMA while suctioning oral secretions as needed.
10. Disposal or Reprocessing
Dispose of single-use LMAs as medical waste per regulations.
Reusable LMAs should be cleaned and sterilized according to the manufacturer’s instructions.
