Objective: To determine the incidence of primary posttonsillectomy hemorrha
ge in a teaching institution by using a uniform technique, including a 3-mi
nute relaxation of retraction before case termination and the use of bismut
h subgallate.
Design: Case series.
Setting: Tertiary care academic pediatric center.
Patients: A 7-year retrospective study was performed by using the medical r
ecords of 1286 children without a bleeding abnormality who underwent tonsil
lectomy (with or without adenoidectomy). A uniform technique, proposed to r
educe hemorrhage, was used for 705 children and was not used for 581 childr
en.
Results: No episodes of primary hemorrhage (onset less than or equal to 24
hours after surgery) occurred, and the incidence of delayed hemorrhage (ons
et >24 hours after surgery) was 1.1% in the study group. The primary hemorr
hage rate of the study group was significantly lower (P =.007) than the rat
e for the reference group (0.0% vs 1.0%), as was the total hemorrhage rate
(1.1% vs 4.1%) and the delayed hemorrhage rate (1.1% vs 3.1%).
Conclusion: A uniform technique including the use of bismuth subgallate and
reassessment of the tonsillar fossae after a 3-minute observation period r
educes the incidence of primary tonsillar hemorrhage in a teaching institut
ion setting.
