Thromboelastography to Assess Age-Related Coagulation Differences in Patients Undergoing Cesarean Delivery
The purpose of the study is to assess potential age-related differences on coagulation profile of patients undergoing Cesarean Section, using thromboelastography (TEG). The investigators will compare coagulation data collected from the study to assess potential differences in coagulation parameters for the following age groups: (i) women less than 35 yrs (ii) women 35 yrs or older.

- Thromboelastography parameters [ Time Frame: 3 days ] [ Designated as safety issue: No ]
Thromboelastography parameters include:
Reaction (r) time Clot Formation (k) time Alpha Angle Maximum Amplitude (MA) Time to maximum rate of thrombus generation (Tmax) Maximum rate of thrombus generation (MRTG) Total Thrombus generated (TTG)
- laboratory coagulation parameters [ Time Frame: 3 days ] [ Designated as safety issue: No ]
- Prothrombin time
- Activated partial thromboplastin time
- Fibrinogen level.
