Management of secondary hemorrhage following pediatric adenotonsillectomy
1Department of Otolaryngology, Royal Children's Hospital, Melbourne, Victoria, Australia.
Insights
Most children (87%) with secondary bleeding after adenotonsillectomy did not need major intervention. Fresh bleeding and low hemoglobin predicted the need for surgery or blood transfusions.
Area of Science:
- Otolaryngology
- Pediatric Surgery
- Hematology
Background:
- Secondary hemorrhage is a known complication following adenotonsillectomy.
- Prompt identification and management of post-tonsillectomy bleeding are crucial in pediatric patients.
Purpose of the Study:
- To determine the incidence of major interventions (surgery or blood transfusion) for secondary hemorrhage post-adenotonsillectomy.
- To identify predictive factors for major interventions in pediatric patients experiencing secondary post-adenotonsillectomy hemorrhage.
Main Methods:
- Retrospective study of pediatric patients admitted to a single institution over 12 years for secondary hemorrhage after adenotonsillectomy.
- Analysis of patient demographics, bleeding presentation, laboratory values, and management outcomes, including need for surgery or transfusion.
Main Results:
- 163 children were admitted for secondary hemorrhage 2-15 days post-surgery.
- 13% (22/163) required major intervention: 5 returned to the operating room, 15 received blood transfusions, and 2 required both.
- Fresh bleeding at presentation (38%) and hemoglobin <100 g/L (36%) were associated with higher rates of major intervention.
Conclusions:
- The majority of pediatric patients with secondary hemorrhage post-adenotonsillectomy can be managed conservatively.
- A 24-hour observation period may be sufficient to identify children requiring major intervention (surgery or transfusion).
- Active bleeding and anemia are key indicators for potential major intervention.
Abstract:
A retrospective study was performed of all patients requiring admission to the Royal Children's Hospital, Melbourne over a 12 year period with secondary haemorrhage following adenotonsillectomy, to determine what percentage of these children received blood transfusions or were returned to the operating room to secure hemostasis, and to identify factors predictive of the need for major intervention. There were 163 children who presented from 2 to 15 days following surgery. Initial management in all cases was establishment of intravenous access, and 151 received intravenous or oral antibiotics. One hundred and forty one were managed without the need for major intervention (87%), including five who had silver nitrate cautery to the tonsillar fossae. Major intervention was required in 22 cases (13%): 5 patients were returned to the operating room for hemostasis; 15 received blood transfusions and 2 underwent both. All surgery was required within 12 h of admissions and all blood transfusions within 24 h. The highest rates of major intervention were in those with fresh bleeding at the time of presentation (38%) and hemoglobin levels less than 100 g/l (36%). For those requiring admission with secondary haemorrhage, a period of observation of 24 h would probably be adequate in the majority of cases to identify those children who will require major intervention by surgery or transfusion.
