Risk factors for secondary post tonsillectomy hemorrhage

Abstract

Introduction: Tonsillectomy is one of the most common worldwide surgical procedures performed by Otolaryngologists which is usually uncomplicated. The most common complication seen after tonsillectomy is hemorrhage. This can be primary or secondary. Primary hemorrhage occurs within twenty four hours after surgery and secondary hemorrhage occurs any time following the initial 24 hours. Although the exact mechanism behind post-tonsillectomy hemorrhage remains unclear. Risk factors can be helpful in pointing toward an etiology. Methods: We performed a retrospective review of 200 patients (above 3 years and of both gender), who were subjected for tonsillectomy with or without adenoidectomy at the ENT Department, Aswan University hospital, and then 50 of them presented with secondary post tonsillectomy hemorrhage (> 24 hours) post-operative, after hospital discharge, between February 2020 and February 2021. Results: Considering risk factors, the patient ages ranged from 4-40 years with a mean of 15.42 years. Most of patients 37 (74%) were male. O positive blood group were predominant in 26 (52%) of patients. Repeated tonsillitis was the most common indication 35 (70%) of patients. bipolar technique was done in most of patients 36 (72%). The majority of patients 31 (62%) were subjected for tonsillectomy without adenoidectomy.
