dren enrolled was 6 years with a standard deviation of 3.4. Overall, there were 5 level 3 bleeds (return to operating room). We found the difference in post-operative hemorrhage rates between the two arms to be less than the non-inferiority margin.


Risk Factors for Pediatric Post-Tonsillectomy Hemorrhage

San Diego, CA The risk of post-tonsillectomy hemorrhage is significantly increased in older children and those with recurrent tonsillitis, obesity and ADHD.

"The main objective of the study was to determine significant pre-operative risk factors for post-tonsillectomy secondary hemorrhage in children, and quantify the magnitude of their risk," said Zorik Spektor, MD.

All of our pediatric tonsillectomy patients experiencing post-operative bleeding from 2005-2010 were identified. The 91 cases were matched with 151 controls that underwent tonsillectomy by the same surgeon on the same day as an identified case. All charts were reviewed, and 41 pre-operative variables were extracted and statistically analyzed.

In the study results, four significant predictors of post-operative bleeding were identified. Performing a tonsillectomy on a child with recurrent tonsillitis (vs. other indications) increased the risk of post-operative hemorrhage by 4.5 times (p<0.0001, 95% confidence intervals 2.41-8.38). Performing a tonsillectomy on a child with attention deficit hyperactivity disorder (ADHD) increased the risk by 8.7 times (p=0.029, 95%CI 1.4-53.6), and obese children increased their bleeding risk by 2.5 times (p=0.044, 95%CI 1.000649-6.76). Older children were more predisposed to post-operative bleeding. For every increase in age by one year, the hemorrhage risk increased by 1.1 times (p=0.0025, 95%CI 1.032-1.162). Children 11 years of age and older had double the risk of bleeding compared to younger children (o
