Tonsillectomy and adeno-tonsillectomy• Second most common pediatric procedure in the US• Reduces health care costs for patients with sleep disordered
breathing and recurrent pharyngitisAdverse Events• Postoperative nausea• Postoperative dehydration• Insufficient pain control• HemorrhageAAO-HNS practice guidelines1
• “Post-tonsillectomy hemorrhage rates with ketorolac range from 4.4% to 18%, and therefore ketorolac use should be avoided”
• “NSAIDs, ketorolac excluded, can be safely used for the postoperative treatment of pain following tonsillectomy”
Post-operative analgesia: Ketorolac/opioid vs. morphine alone
• Obtaining analgesia while reducing risk of respiratory depression

Evaluation of post-tonsillectomy hemorrhage with use of intraoperative ketorolac in the pediatric population
RESULTS
Overall postoperative hemorrhage rate with intraoperative use of of ketorolac tromethamine:
4.7%
National post-tonsillectomy hemorrhage rate:2 – 6%
National post-tonsillectomy hemorrhage rate with intraoperative ketorolac: 4.4 – 18%
METHODSl Retrospective chart review, Jan - Dec 2011l 3 – 18 yrs oldl Single fellowship-trained surgeonl All bilateral tonsillectomy or tonsillectomy plus adenoidectomy
l ASA physical status 1 & 2l Standardized operation:
l Extracapsular, used monopolar electrocauteryl 0.5 mg/kg IV ketorolac given intraoperativelyl Dexamethasone 0.4 mg/kg IV intraoperativelyl Ondansetron 0.1 mg/kg IV intraoperativelyl All patients were intubated and received inhalational anesthetic. Most received fentanyl 0.5 mcg/kg IV
l Post-operative analgesia (after discharge): ibuprofen, acetaminophen with or without codeine
Level 1 hemorrhage• Any report of post-operative hemorrhage, with or without clinical
evidence• 8/422 = 1.9%
Level 2 hemorrhage• Required inpatient admission• 4/422 = 0.9%
Level 3 hemorrhage• Cases with return to the OR• 8/422 = 1.9%
OBJECTIVES
To evaluate the post-tonsillectomy hemorrhage rate in patients receiving intraoperative ketorolac at our institution and compare to national average.
Ketorolac is an effective analgesic option that did not demonstrate increased post-tonsillectomy hemorrhage rates compared to published rates without NSAID use in the healthy pediatric population examined here.
These findings encourage a re-evaluation of current practice guidelines given the risks associated with other analgesic options in this subset of patients
CONCLUSION
DISCUSSION
• 75% of levels I and II bleeds – indication for surgery was
infectious (e.g. chronic tonsillitis or recurrent streppharyngitis)• Retrospective study; no control group• Lack of perceived need for better post-operative paincontrol?• Many surgeons aware of risks of ketorolac but limited
knowledge of benefits
