Diagnostic Value of the Pediatric Bleeding Questionnaire in Prediction of Bleeding in Minor Surgery.

Abstract

Preoperative coagulation tests have not been shown to be effective in predicting bleeding complications. The Pediatric Bleeding Questionnaire (PBQ) is a proven and sensitive tool for diagnosing children with a predisposition to bleeding. The aim of this study was to evaluate the usefulness of PBQ as a preoperative screening tool for the prediction of bleeding after minor surgical interventions. Preoperative coagulation tests and PBQ were performed in all patients who underwent minor surgery. The postoperative bleeding status was evaluated and then compared with the coagulation tests and PBQ of the patients. Evaluation was made of a total of 706 patients, comprising 91.2% males and 8.8% females, with a mean age of 4.8 years (median: 4y, QR: 1 to 7y). Prolongation in coagulation tests was observed in 131 (18.5%) patients. Repeated tests in 116 patients were within the normal range, and 5 patients received treatment. Postoperative bleeding occurred in 4 (0.5%) patients. The relationship between coagulation tests and postoperative bleeding was not significant. PBQ was found to be ≥2 in 14 patients, but none of these patients had postoperative bleeding. No significant relationship was found between postoperative bleeding status and PBQ (p:0.77). The sensitivity, specificity, positive predictive, and negative predictive values of PBQ were 0%, 98%, 0%, and 97.4%, respectively. The results of this study demonstrated that neither coagulation tests nor PBQ will be sufficient to predict bleeding after minor surgery, that prolongation in coagulation tests does not always indicate a bleeding tendency, and that bleeding history should also be recorded in detail.
