Purpose Of The Study:
Thromboelastography provides a holistic picture of blood coagulation including fibrin formation, cross, linking and fibrinolysis. Coagulaopathy in end stage renal disease (ESRD) is multifactorial. The present evaluated the thromboelastographic profile of ESRD patients and compared it to conventional tests of coagulation.
Study Design:
In this observational case control study, fifty ESRD patients and 50 controls were recruited. Venous samples were withdrawn and platelet count, International Normalization Ratio and fibrinogen levels were measure. Simultaneously a thromboelastography (TEG) was performed. All samples were drawn prior to initiation of dialysis.
Results:
The fibrinogen concentration was higher in the ESRD group compared to control (455.51±83.39 vs. 233.84±71.71 mg/dl, P<0.05). The maximum amplitude in ESRD group was 76.94 ± 15.11 mm, which was significantly higher than control group 65.10±10.31 mm (P<0.05).Out of 50 ESRD patients,39 had maximum amplitude (MA) >73mm, 3 had MA <55 mm while 8 patients had normal MA. Further, it was seen that in four out if the five patients whose INR was greater than 1.5. TEG was hypercoaguable. Also, three patients whose platelet count was less than x105/dl had normal thromboelastographs. Two patients with normal platelet count, fibrinogen and INR had hypercoaguable thromboelastographs. Thromboelastography could detect fibrinolysis in 5 patients of end stage renal disease.
Conclusion:
The present study demonstrated that INR, platelet count and fibrinogen levels do not reflect the actual coagulation status in patients of ESRD. Thromboelastography is a better tool to detect coagulopathy in this group of patients.

It would be easy to compare two samples using a significance alpha level of 0.05. In other words, there is only one sample pair to be compared. However, it would be difficult to identify a significantly different sample if the number...

Renal clearance is often associated with the renal glomerular filtration rate (GFR), which represents the rate at which plasma is filtered through the glomeruli in the kidney. When drug reabsorption is minimal and there is no active secretion, renal clearance is closely related to the...
