Can you intubate with a LMA?

Can you intubate with a LMA?

Intubation through an intubating LMA such as the LMA Fastrach produces higher success rates than intubating through a standard LMA (approximately 95% and 80%, respectively). The LMA Classic and LMA Unique limit the size of the endotracheal tube (ETT) that can be passed. A 6.0 ETT fits through LMA sizes 3 and 4.

How do you insert intubating LMA?


  1. deflate ILMA cuff.
  2. lubricate ILMA mask on the posterior surface using water soluble lubricant and rub the lubricant over the anterior hard palate.
  3. release cricoid pressure (if present) prior to inserting the iLMA.

How is LMA size calculated?

We advocate here an alternative formula:LMA ™ size = 1 + BWru/20, where BWru indicates body weight (in kilograms) rounded up at the first digit.

Which is the appropriate size of LMA?

Results: Our findings indicate that size 1 LMA for patients weighing less than 7 kilograms, size 1.5 LMA for patients weighing 7 to 11 kilograms, size 2 LMA for patients weighing 11 to 17 kilograms, and size 2.5 LMA for patients weighing 15 to 28 kilograms is appropriate.

What is a serious complication related to the insertion of a Laryngeal Mask Airway?

Laryngospasm, nausea, vomiting, arytenoid dislocation, vocal cord paralysis, sore throat, and cough were considered as complications of using LMA.

Does an LMA provide oxygenation and ventilation?

Laryngeal Mask Airway When compared with the endotracheal tube, the LMA provides equivalent ventilation33,34; successful ventilation during CPR is reported in 71.5% to 97% of patients.

What is the intubating LMA?

the intubating LMA (Fastrach™) is a specially designed supraglottic airway device (SAD) that can be used as a conduit to facilitate intubation rescue device for failed intubation (i.e.. the “can’t intubate can ventilate” situation) e.g. patients with known cervical spine injuries (ILMA use results in less spinal movement than direct laryngoscopy)

How to use the Ilma device for intubation?

1 Hold the ILMA device handle while gently inserting the lubricated ETT into the airway shaft 2 Advance the ETT, inflate the cuff and confirm intubation using ETCO2 More

Can we predict difficult airway intubation in the critically ill?

Airway assessment and prediction of the difficult airway is an inexact science, particularly in the critically ill and in emergency situations In patients who have never been intubated, there is no method of prediction of difficult intubation that is both highly sensitive and highly specific

What is the role of the laryngeal mask airway in intubation?

The intubating laryngeal mask airway facilitates tracheal intubation in the lateral position. Anesth Analg. 2004 Mar;98 (3):858-61 PMC1350644.
