Which factor increases the risk of a sore throat following laryngeal mask airway (LMA) use?

Higher cuff pressures in a laryngeal mask airway (LMA) can significantly increase the risk of a sore throat postoperatively. When the cuff pressure is elevated, it exerts more pressure against the surrounding tissues in the pharynx and larynx, which can lead to edema, ischemia, and irritation of the mucosa. This trauma results in inflammation and discomfort, causing the patient to experience a sore throat after removal of the LMA.

Maintaining appropriate cuff pressures is crucial for minimizing complications associated with LMA use. Keeping the pressure within the recommended range can help prevent excessive tissue irritation and reduce the likelihood of sore throat, ensuring a more comfortable recovery for the patient. Understanding the relationship between cuff pressures and soft tissue integrity during airway management is essential for optimal patient care.
