Abstract:
:The objective of this study is to analyze the major causes of abnormal findings seen in the preoperative coagulation tests of asymptomatic pediatric patients and to discuss the usefulness of coagulation tests prior to minor surgery. Among patients who received minor surgery in Kyung Hee University Medical Center from March 2008 to April 2015, a total of 7114 pediatric patients (ages 1-18) were included in our study. Of these, 226 (3.1%) were referred to the pediatrics hematology-oncology department because of abnormal preoperative coagulation tests. A review of the coagulation tests indicate the majority (n = 216, 95.5%) have prolonged activated partial thromboplastin time (aPTT), whereas a smaller number (n = 10, 4.5%) have prolonged prothrombin time international normalized ratio (PT INR). When the coagulation tests were repeated, 136 displayed abnormal findings again. Of these 136 patients, 128 patients underwent mixing tests, and 127 showed results of correction and were composed as follows: normal (n = 83), subnormal (n = 26), factor deficiency (n = 15), and lupus anticoagulant positive (n = 3). Breakdown by factor deficiencies was as follows: (i) factor XII (n = 9), (ii) factor IX (n = 2), (iii) factors XII and IX (n = 1), (iv) factor VIII (n = 1), (v) factor XI (n = 1), (vi) von Willebrand factor (vWF; n = 1), and (vii) factor V (n = 1). Each factor activity range was mild (21%-39%), so no patients received preoperative medications or clotting factors/blood products. Even in the presence of factor deficiencies, bleeding symptoms were mild and postoperative complications did not occur. These results suggest that coagulation tests may not be needed in healthy children and should be reserved for patients with positive bleeding and/or family history.
