NCT01715610

Brief Summary

This study aims to look at the necessity for prescribing antibiotics post-drainage of peritonsillar abscesses (PTA). This will be a single-blinded randomized-control trial with two arms - patients receiving placebo versus those receiving a seven day course of oral Amoxicillin-Clavulanic acid. The main objective measure will be to assess if there is resolution of the peri-tonsillar abscess and there has been no reaccumulation. Patients will be blinded to whether they receive placebo or amoxicillin-clavulanic acid. Patients will be phoned after 7 days to assess if their symptoms have resolved via an over the phone questionnaire. Anaerobic and aerobic cultures will be obtained.

Outcome Measures

Primary Outcomes (1)

  • Re-accumulation of the patient's peri-tonsillar abscess

    Patients will be followed up at 2 time points - 7 days and 30 days. At 7 days, the patient will be called and asked to see if they have had resolution of their symptoms. We will again call within 30 days to see if symptoms have returned within that time frame.

    30 days

Study Arms (2)

Antibiotic Clavulin or Clindamycin

ACTIVE COMPARATOR

Patient's in this arm are randomized by random-number generator to receive antibiotics. This is for a 7 day course of antibiotics. Those that are allergic to penicillin will receive clindamycin. Randomization occurs after knowledge of the patient's allergy status.

Drug: ClavulinDrug: Clindamycin

Placebo

PLACEBO COMPARATOR

Patient's randomized to this arm post-drainage will receive placebo and not receive antibiotics

Drug: Randomization to Placebo

Interventions

Patients will be randomized to the antibiotic or placebo arm via a random number generator.

Antibiotic Clavulin or Clindamycin

Patient's post-drainage of antibiotics will receive placebo and not receive antibiotics

Placebo

Patients will be randomized to the antibiotic or placebo arm via a random number generator

Antibiotic Clavulin or Clindamycin
