“…The levels of NO and urea were determined in serum and saliva by means of automated enzymatic colorimetric assays, respectively, EnzyChromTM Nitric Oxide Synthase Assay and EnzyChromTM Urea Assay Kit (BioAssay Systems), according to the manufacturer's recommendations. The specimens were read by using a microplate reader (Stat Fax, model 2100, Awareness Technology) (Duarte et al, 2020(Duarte et al, , 2022.…”

ObjectiveThis work measures the intra‐operative bleeding in end‐stage renal disease patients and assesses whether laboratory coagulation tests and nitrogenous compounds are related to a higher bleeding risk.MethodsLaboratory 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.ResultsHaemostatic 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.ConclusionIt was not possible to associate any laboratory test or nitrogenous compounds present in the blood and saliva with an increased bleeding.
