Study ObjectiveTo estimate the incidence of coagulopathy in patients with intrahepatic cholestasis inhepatic cholestasis of pregnancy (ICP).DesignRetrospective cohort investigation.SettingUniversity medical center.MeasurementsThe records of 319 parturients who met study inclusion criteria were reviewed for various laboratory values. The primary outcome was the incidence of abnormal hemostasis, defined as prothrombin time (PT) greater than 14.5 seconds (INR>1.2). The incidence of postpartum hemorrhage was evaluated as a secondary outcome.Main ResultsThe incidence (95% CI) of abnormal PT was 0% (0 to 1.8). Other coagulation tests [partial thromboplastin time (PTT) and platelet count] were also normal, even in study subjects with significant (>5 times) elevation of liver enzymes. The incidence of postpartum hemorrhage after vaginal delivery was 2.4% (4 of 208 pts) and 6.3% (7 of 111 pts) after Cesarean delivery.ConclusionsCoagulation abnormalities are rare in pregnant patients with ICP, even when a strict criterion is utilized (INR<1.2). The use of neuraxial anesthesia and/or analgesia may not necessarily be delayed in parturients with isolated ICP.Copyright © 2014 Elsevier Inc. All rights reserved.
