From the Guidelines

Dexamethasone (Decadron) is not specifically recommended for the treatment of peritonsillar abscess in the provided evidence, but it is recommended for use in tonsillectomy procedures, which may be performed to treat peritonsillar abscess in some cases. The provided evidence, 1, focuses on the clinical practice guideline for tonsillectomy in children, which includes a strong recommendation for administering a single, intraoperative dose of intravenous dexamethasone to children undergoing tonsillectomy.

Key Points

  • The guideline recommends dexamethasone for tonsillectomy procedures, but does not specifically address its use in peritonsillar abscess treatment.
  • Dexamethasone is typically used to reduce inflammation and pain associated with surgical procedures.
  • The evidence does not provide information on the use of dexamethasone as an adjunct to antibiotics and drainage for peritonsillar abscess.

Considerations

  • In clinical practice, dexamethasone may be used off-label for peritonsillar abscess treatment, but this is not supported by the provided evidence.
  • The decision to use dexamethasone in peritonsillar abscess treatment should be based on individual patient needs and clinical judgment, taking into account the potential benefits and risks of steroid use in the setting of infection, as referenced in 1.

Treatment Approach

  • Peritonsillar abscess treatment typically involves antibiotics and drainage, with or without tonsillectomy.
  • If tonsillectomy is performed, dexamethasone may be administered according to the guideline recommendations, as stated in 1.

From the Research

Treatment of Peritonsillar Abscess

  • Peritonsillar abscess is a deep infection of the head and neck, and its treatment may involve drainage of the abscess, antibiotic therapy, and supportive therapy for maintaining hydration and pain control 2.
  • Corticosteroids may be helpful in reducing symptoms and speeding recovery in patients with peritonsillar abscess 2, 3, 4.
  • A study published in 2005 found that an outpatient medical treatment protocol involving hydration, antibiotics, steroids, and good pain control was successful in treating peritonsillar abscess in 95.9% of patients 3.
  • Another study published in 2004 found that the use of a single high dose steroid treatment in addition to intravenous antibiotic therapy was more effective than the use of an antibiotic alone in relieving symptoms of peritonsillar abscess 4.

Use of Dexamethasone (Decadron) in Treatment

  • Although the provided studies do not specifically mention the use of Dexamethasone (Decadron) in the treatment of peritonsillar abscess, they do suggest that corticosteroids may be helpful in reducing symptoms and speeding recovery 2, 3, 4.
  • The study published in 2005 mentions the use of steroids as part of an outpatient medical treatment protocol, but does not specify the type of steroid used 3.
  • The study published in 2004 mentions the use of a single high dose steroid treatment, but also does not specify the type of steroid used 4.

Antibiotic Therapy

  • Peritonsillar abscesses are polymicrobial infections, and antibiotics effective against group A streptococcus and oral anaerobes should be first-line therapy 2, 5.
  • The choice of antibiotics after surgical drainage of the abscess is controversial, but results of many studies support the resistance of grown bacteria to many antibiotics and the potential importance of anaerobic bacteria in development of peritonsillar abscesses 5.
