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
