In this group, 17.2% of patients with a posttonsillectomy hemorrhage bled
again after medical management--either monitoring with supportive therapy or a procedure to control the bleeding was commenced.
The ten-year-old drew considerable applause from the crowd before the start, but that turned to concern for the horse's future after it emerged he had bled
profusely during the race.
A [[chi].sup.2] analysis was used to compare two characteristics (the patient's gender and indication for surgery) of those patients who had and had not bled
. The Student's t test was used to examine the influence of age on the incidence of post-tonsillectomy bleeding.
By study design, only patients with an elevated INR who had not bled
were enrolled, which leaves open the possibility of a "healthy cohort" bias.
Kennedy and Strom supported this conclusion in their study entitled, "A comparison of postoperative bleeding incidence between general and local anesthesia tonsillectomies."  A close look at their data reveals that 15 of 120 patients (12.5%) who received lidocaine with epinephrine developed postoperative bleeding, while only 1 of 72 patients (1.4%) who were not injected with epinephrine bled
. This statistically significant difference is comparable to the threefold increase in bleeding seen in our study.
