INTRODUCTION: Post-tonsillectomy hemorrhage (PTH) is a serious complication after a tonsillectomy. Utility of lab work at presentation for PTH was low. This study aims to determine the frequency and type of labs drawn at emergency department (ED) presentation and assess the incidence of uncovering a previously unidentified coagulopathy.
METHODS: A retrospective chart review was performed on pediatric patients who were seen in the ED after tonsillectomy at a tertiary care children's hospital from 2017 to 2019. Exclusion criteria were the following: no tonsillar bleed, history of known coagulopathy, treated by outside provider, ≥18 years old. Lab work included complete blood count (CBC), prothrombin time (PT), partial thromboplastin time (PTT), and von Willebrand factor (VWF).
RESULTS: 364/723 (50.3%) patients met inclusion criteria. 179/364 (49.2%) patients were male and 309/364 (84.9%) patients were Caucasian. Average age at surgery was 8.12 years (SD = 4.0) and average post-operative day at presentation was 6 days (SD = 2.1). Operative control of bleed was performed in 68/364 (18.7%) patients. 334/364 (91.8%) patients had labs drawn in the ED. 64/334 (19.1%) patients were anemic (hemoglobin (Hgb) < 11), 46/334 (13.8%) patients had thrombocytosis (platelets>450,000), 10/334 (3.0%) had elevated PTT and 8/334 (2.4%) had elevated PT. Hematology was consulted in 14/364 (3.8%) patients of whom 6/14 were diagnosed with von Willebrand disease and 1/14 with factor VII deficiency. Aminocaproic acid was used in 8/364 (2.2%) patients due to elevated PTT in 3/8 and multiple episodes of bleeding in 5/8.3/364 (0.8%) patients needed a blood transfusion. No difference was found in incidence of abnormal lab work in patients who did and did not need operative control of bleed (p = .125). Of the 334 patients who had ED labs drawn, 7 (2.1%) had an uncovered coagulopathy.
CONCLUSION: Uncovering incidental coagulopathies is rare in patients who present with PTH. Though anemia was the most common abnormality noted, only a small percentage required transfusion, with all having abnormal vital signs. Thrombocytosis was the next common abnormality, and this can be seen in an inflammatory state. Developing algorithms is necessary to better guide appropriate lab work in patients who present with PTH and to provide optimal value of care to patients.
