Methods:Laboratory tests were performed on the day of surgery and some patients with thrombocytopenia and values above the normal levels of international normalised ratio (INR), thrombin time (TT) and activated partial thromboplastin time (aPTT) were identified. Results: Haemostatic time ranged from 2 to 35 min (mean of 8.51 min) after suture. Bleeding volume ranged from 0.02 to 67.06 mL (mean of 4.38 mL) and the bleeding volume per minute ranged from 0.05 to 2.10 mL/min (median of 0.6 mL/min). Only seven patients (16.27%) had abnormal bleeding (more than 0.6 mL/min). Spearman's coefficient showed weak correlations between bleeding volume (mL/min) and serum urea (r = 0.226), TT (r = 0.227), plasma urea (r = 0.148) and creatinine (r = 146), as well as very weak correlations with all other variables (r < 0.140) such as age, haemodialysis time, glycaemia, glycated haemoglobin, platelets, INR, aPTT and fibrinogen. Conclusion: It was not possible to associate any laboratory test or nitrogenous compounds present in the blood and saliva with an increased bleedingeng© 2023 The Authors.
