Hoarseness is common after adult cardiac surgery, often linked to endotracheal tube (ETT) movement during positioning. Longer intubation times predict more severe hoarseness, which is usually temporary.

Area of Science:

  • Anesthesiology
  • Cardiothoracic Surgery
  • Laryngology

Background:

  • Hoarseness is a frequent complication following adult cardiac surgery.
  • The precise incidence, severity, and duration of hoarseness require further investigation.
  • Endotracheal tube (ETT) movement during surgical positioning may contribute to post-operative hoarseness.

Purpose of the Study:

  • To determine the incidence, severity, and duration of hoarseness in adult cardiac surgery patients.
  • To analyze the displacement of the endotracheal tube (ETT) during neck extension for sternotomy.
  • To identify predictors of hoarseness severity, such as intubation duration and ETT migration.

Main Methods:

  • Prospective study conducted in a university hospital setting.

  • Seventy-two adult patients undergoing elective cardiac surgery were included.
  • Endotracheal tube (ETT) migration was measured using fiberoptic bronchoscopy; hoarseness was assessed post-extubation.

    • Main Results:

    • The endotracheal tube (ETT) migrated an average of 11 mm away from the carina during surgical positioning.
    • Hoarseness was reported in 32% of patients, with a mean duration of 4 days.
    • Intubation time was a significant predictor of hoarseness severity (p=0.0001).

    Conclusions:

    • Hoarseness is a common outcome after adult cardiac surgery.
    • The severity of hoarseness is significantly correlated with the duration of endotracheal intubation.
    • ETT displacement during sternotomy positioning may lead to vocal cord or recurrent laryngeal nerve injury, causing hoarseness.
