Area of Science:

  • Anesthesiology
  • Patient Safety

Background:

  • Postoperative sore throat (PS T) is a common complication following general anesthesia, with reported incidence up to 62% in adults.
  • Several factors are associated with increased PST risk in adults undergoing tracheal intubation, including female sex, younger age, pre-existing lung disease, prolonged anesthesia duration, and blood-stained tracheal tubes upon extubation.

Purpose of the Study:

  • To identify risk factors for postoperative sore throat (PST) in adults and children.
  • To evaluate the effectiveness of different airway management strategies in reducing PST incidence.

Main Methods:

  • Review of literature identifying risk factors and preventative measures for PST in adults and children.
  • Analysis of data concerning tracheal intubation, supraglottic airway devices, and associated cuff pressures.

Main Results:

  • In adults, factors like female sex, younger age, pre-existing lung disease, prolonged anesthesia, and blood-stained tubes increase PST risk. The i-gel(™) supraglottic airway device showed a lower PST incidence compared to tracheal intubation.
  • In children, respiratory tract disease increases PST risk. Supraglottic airway devices, oral intubation, and cuffed tracheal tubes are beneficial in reducing PST. Limiting cuff pressures for both tracheal tubes and supraglottic airway devices may also decrease incidence.

Conclusions:

  • Patient-specific factors and airway device selection significantly influence PST incidence.
  • Optimizing airway device selection, intubation technique, and cuff pressure management are crucial for minimizing postoperative sore throat in both adult and pediatric populations.
