Study summary

This is a prospective, observational study to determine the association between preoperative fasting duration and post-tonsillectomy pain scores in the post-anesthesia care unit (PACU) among pediatric patients undergoing tonsillectomy with or without adenoidectomy and/or tympanostomy tube placement. The primary outcome is the post-tonsillectomy pain score, with the secondary outcomes as total postoperative opioid consumption, PACU length of stay, and hospital length of stay.

What researchers measure

Primary outcomes

  1. Post-tonsillectomy pain scores

    Pain scores will be assessed in the post-anesthesia care unit (PACU) and on the inpatient floor (if admitted) every 15 minutes - 4 hours for the duration of their recovery until hospital discharge. The patient is asked to rate their pain on a scale of 0-10 with 0 being no pain and 10 being worst pain imaginable.

    Time frame: 2 - 24 hours post-op

Secondary outcomes

  1. Postoperative opioid consumption

    The amount of opioid pain medication the patient received following their surgery until hospital discharge.

    Time frame: 2 - 24 hours post-op

  2. PACU length of stay

    Amount of time between admission to the post-anesthesia care unit (PACU) and discharge from the PACU.

    Time frame: 1 - 2 hours post-op

  3. Hospital length of stay

    Amount of time between admission to the pre-op unit prior to surgery until discharge from the hospital.

    Time frame: 4 - 24 hours
