NCT01514591

Brief Summary

The purpose of the study is to assess the coagulation changes that occur in laboring patients undergoing non-elective (intrapartum)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.

Outcome Measures

Primary Outcomes (1)

  • Estimated blood loss; Coagulation data (Thromboelastography, Laboratory)

    This study will allow us to collect more information about the hemostatic effects that occur during non-elective Cesarean delivery. This information will add to current knowledge base (which we have published) about coagulation changes in the peripartum period in patients undergoing non-elective Cesarean section.

    pre and post cesarean delivery, an expected average of 75 minutes

Secondary Outcomes (1)

  • Hematologic indices

    Pre and post cesarean delivery, an expected average of 75 minutes

Study Arms (1)

Non-elective Cesarean Delivery

We will only enroll patients undergoing non-elective CS with an 'epidural top-up' for surgical anesthesia. By definition, our study will only apply to laboring women with working labor epidurals (which were provided for labor analgesia).

Eligibility Criteria

Age18 Years - 40 Years
Sexfemale
Healthy VolunteersYes
Age GroupsAdult (18-64)
Sampling MethodNon-Probability Sample
Study Population

Obstetrical laboring patients who are undergoing non-elective Cesarean delivery with an 'epidural top up' for surgical anesthesia.

You may qualify if:

  • Obstetric in-patients
  • Laboring patients with Epidurals for Labor Analgesia going for non-elective Cesarean
  • Patients of all ethnic backgrounds will be included
  • Singleton pregnancy
  • ASA 1 or 2

You may not qualify if:

  • Patients with underlying coagulation disorders.
  • Patients with thrombocytopenia (platelet count \<100).
  • Patients with pregnancy-induced hypertension, pre-eclampsia.
  • Patients requiring the following medications prior to surgery: NSAIDS, aspirin, anticoagulants.
  • Patients requiring elective Cesarean delivery.
  • Patients with significant obstetric or medical disease.
  • No patients \<18 years of age will be recruited.
