Postoperative nonsteroidal anti-inflammatory drugs and risk of bleeding in pediatric intracapsular tonsillectomy.

OBJECTIVES In light of current FDA guidelines on opioid use in children, we sought to determine the risk of post-tonsillectomy hemorrhage (PTH) in children who received ibuprofen with acetaminophen versus those who received narcotic with acetaminophen for postoperative pain control. METHODS This was an IRB-approved retrospective chart review of patients at a tertiary-care pediatric center. The medical records of 449 children who received acetaminophen and ibuprofen following intracapsular tonsillectomy with or without adenoidectomy were reviewed (NSAID group) and compared with medical records of 1731 children who underwent intracapsular tonsillectomy and received acetaminophen with codeine or hydrocodone with acetaminophen postoperatively (narcotic group). Main outcome measure was the incidence of PTH requiring return to the operating room. Secondary outcome measures included incidence of primary PTH, secondary PTH, and postoperative evaluation in the emergency department or readmission for pain and/or dehydration. RESULTS Incidence of PTH requiring return to the operating room was higher in the NSAID group (1.6%) compared with the narcotic group (0.5%), P=0.01. Incidence of primary PTH was significantly higher in the NSAID group (2%) versus the narcotic group (0.12%), P<0.0001. Incidence of secondary PTH was 3.8% in the NSAID group and 1.1% in the narcotic group (P<0.0001). CONCLUSION Use of ibuprofen after intracapsular tonsillectomy in children is associated with statistically significant increase in PTH requiring return to the operating room, as well as an increase in overall rates of both primary and secondary PTH. Ibuprofen provides pain control that is at least equivalent to narcotic and is not associated with respiratory depression. Further study of ibuprofen use in the post-tonsillectomy patient is warranted.
