Fasting Time and Post-tonsillectomy Pain

May 5, 2026 updated by: Brittany Willer

Fasting Duration and Post-tonsillectomy Pain in Pediatric Patients

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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Post-tonsillectomy pain scores
Time Frame: 2 - 24 hours post-op
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.
2 - 24 hours post-op

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Postoperative opioid consumption
Time Frame: 2 - 24 hours post-op
The amount of opioid pain medication the patient received following their surgery until hospital discharge.
2 - 24 hours post-op
PACU length of stay
Time Frame: 1 - 2 hours post-op
Amount of time between admission to the post-anesthesia care unit (PACU) and discharge from the PACU.
1 - 2 hours post-op
Hospital length of stay
Time Frame: 4 - 24 hours
Amount of time between admission to the pre-op unit prior to surgery until discharge from the hospital.
4 - 24 hours
