Introduction: The thromboelastograph (TEG) is a tool that enables the global assessment of blood clotting to be made from a single blood sample. It provides a graphic representation of clot formation and lysis from which 5 parameters are measured each representing different components of clot formation and stabilisation in the point of care setting. We evaluated the TEG profiles of the following patient groups over an 6 month period: 1) Elective LSCS ASA 1 term patients (n=200), 2) patients with pre-eclampsia and thrombocytopenia (n=30) and patients with major obstetric haemorrhage (n=5).

Methods: In this prospective observational study we used the Haemoscope 500 (IL, USA) to measure TEG profiles in the point of care setting. 1ml of fresh whole blood was obtained with informed consent from the participants for each TEG profile. The following data was collected: clotting time (R), Clot kinetics (k), alpha angle, clot strength (MA), haemostasis profile (CI) and clot stability (LY30)

This is the first study evaluating TEG profiles in term ASA 1 pregnant women using kaolin activated whole blood. We believe that the use of TEG can give us information on the global coagulation status of the patient reliably and quicker than the traditional method of FBC and coagulation screens in guiding transfusion therapy. This may potentially reduce the need for transfusion of blood products with its associated risks (known and unknown) and potentially reduce the cost associated with transfusion. Evaluation of the TEG data in parturients with PET and thrombocytopenia shows that the platelet function (normal range MA) is maintained even in the presence of a lower platelet count. There are many more applications of point of care TEG for example in the evaluation of global coagulation status of patients prior to regional anaesthesia or predicting the thrombotic risk in postoperative patients in the general population.
