Question

Which factors are responsible for sore throat following laryngeal mask airway (LMA) use _________.

1) Cuff overinflation
2) Long surgical duration
3) Positive pressure ventilation
4) Use of air in inspired gas mixture

Answer 1

Cuff overinflation, long surgical duration, positive pressure ventilation, and use of air in inspired gas mixture are factors responsible for sore throat following laryngeal mask airway (LMA) use. Hence, all the options are correct.

Step-by-step explanation:

The factors responsible for sore throat following laryngeal mask airway (LMA) use are cuff overinflation, long surgical duration, positive pressure ventilation, and use of air in the inspired gas mixture.

Overinflating the cuff of the LMA can cause pressure on the throat tissues, leading to a sore throat. Prolonged surgical duration can also contribute to throat irritation. The positive pressure ventilation exerted by the LMA can cause dryness and irritation of the throat.

Additionally, using air in the inspired gas mixture can further contribute to the dryness and irritation of the throat. Therefore, all the options can be considered correct.
