Thromboelastography to Assess Hemostatic Changes in Patients Undergoing Elective Cesarean Delivery.

November 6, 2009 updated by: Stanford University
The purpose of the study is to assess the coagulation changes that occur in patients undergoing elective Cesarean delivery using thromboelastography (TEG). We will compare coagulation data to assess potential coagulation changes associated with hemoglobin changes before and after surgery, and related to estimated blood loss.

Detailed Description

The purpose of the study is to assess the coagulation changes that occur in patients undergoing elective Cesarean delivery using thromboelastography (TEG). TEG is a point-of-care device which measures the viscoelastic properties of clot formation. This device can provide rapid and detailed information about coagulation changes in the perioperative period. We will compare coagulation data collected from the study to assess potential coagulation changes associated with Hemoglobin changes before and after surgery, and related to estimated blood loss.

Description

Inclusion Criteria:

  • Patients with thrombocytopenia.
  • Patients with pregnancy-induced hypertension, pre-eclampsia.
  • Patients requiring the following medications prior to surgery: NSAIDS, aspirin, anticoagulants.
  • Patients requiring non-elective Cesarean delivery.
  • Patients with significant obstetric or medical disease.
  • No patients <18 years of age will be recruited.
