Routine predelivery coagulation screening in previous cesarean patients: impact on patient management

Coagulation profiles (platelet count, prothrombin time, partial thromboplastin time) obtained as part of predelivery screening were examined in patients who presented for delivery with a history of previous cesarean section. Coagulation test results (N = 1439) were reviewed from charts of 482 patients. No change in patient management occurred and no cesarean sections or vaginal deliveries were deferred as a result of the laboratory tests. There were no hemorrhagic complications. No blood products were transfused as a result of the tests. Routine coagulation evaluation is not justified for subsequent delivery of patients who had a previous cesarean section.
