What airway device is contraindicated if the patient has recently eaten?

What airway device is contraindicated if the patient has recently eaten?

For two reasons, the LMA is also relatively contraindicated as a routine airway in patients who have a risk of regurgitation and/or active vomiting of gastric contents or have a large amount of blood present in the upper airway.

When is an LMA used?

The laryngeal mask airway (LMA) is an acceptable alternative to mask anesthesia in the operating room. It is often used for short procedures when endotracheal intubation is not necessary.

What is the difference between LMA and ETT?

Conclusion: The LMA does not provide safe patent airway to facilitate bedside PDT in critically sick population on controlled ventilation. The ETT is safer for controlled ventilation and should be continued to secure the airway for this purpose until a better alternative is available.

What causes a difficult airway?

The main factors implicated in difficult endotracheal intubation were poor dental condition in young patients, low Mallampati score and interincisor gap in middle-age patients, and high Mallampati score and cervical joint rigidity in elderly patients.

What is the ASA airway management algorithm?

The algorithm was introduced by ASA as a practice guideline in 1993. In 2003, the ASA task force presented a revised algorithm that essentially retained the same concept but recommended a wider range of airway management techniques than was previously included, based on more recent scientific evidence and the advent of new technology.

When did the American Society of Anesthesiologists adopt the difficult airway guidelines?

This revision includes data published since the “Practice Guidelines for Management of the Difficult Airway” were adopted by the American Society of Anesthesiologists in 1992; it also includes data and recommendations for a wider range of management techniques than was previously addressed.

What is the difficult airway algorithm?

The difficult airway algorithm ( Figure 83-1) is organized to help practitioners navigate various complications that arise during airway management.

Who should use the algorithms of Anesthesiology?

Both algorithms are primarily intended for use by anesthesiologists or by individuals who deliver anesthetic care and airway management under the direct supervision of an anesthesiologist. The guidelines apply to airway management during all types of anesthetic care and anesthetizing locations, and to patients of all ages.
