To Compare TEG (Thrombelastography) and Conventional Tests in CKD Patients

Institute of Liver and Biliary Sciences, India100 enrolled

Overview

Background: Coagulopathy in chronic kidney disease is multifactorial. Both hypocoagulopathy and hypercoaguability are seen. Conventional tests of coagulation (CCTs) end at the formation of thrombin, and do not take into account the interaction of coagulation factors, platelets, RBC etc. By overcoming the above deficiencies, thromboelastography provides a holistic picture of blood coagulation. The present study evaluated the TEG profile of ESRD patients and compared it to CCTs and to controls. Methods: 50 ESRD patients and 50 controls were recruited for the study. Venous samples were withdrawn and platelet count, INR and fibrinogen levels were measured. Simultaneously a Thromboelastography was performed. All samples were drawn prior to initiation of dialysis.

Outcomes

Primary Outcomes

To compare the maximum amplitude on a thromboelastography in patients of chronic kidney disease stage 5 with normal controls.

Maximum amplitude in whole blood will be measures by a standard kaolin thromboelastography in all patients and controls.

Time frame: 0 hr

Secondary Outcomes

To correlate the maximum amplitude with platelet count and fibrinogen levels in patients of chronic kidney disease

the maximum amplitude obtained on an thromboelastography denotes clot strength which depends on platelet count and fibrinogen levels. thus an attempt will be made to corelate these values with fibrinogen levels and platelet count.

Time frame: 0 hr
