NCT ID: NCT00685932 Completed - Pregnancy Clinical Trials

Mobius® Post-cesarean Pain Randomized Control Trial

Start date: July 2008
Phase: N/A
Study type: Interventional

The purpose of this study is to investigate whether the use of the Mobius® retractor decreased post-operative pain after cesarean section verses conventional retractor use. Based on clinical experience and a pilot study, we suspect that the retractor will decrease overall pain as well as lateral pain.

NCT ID: NCT00456547 Completed - Hemorrhage Clinical Trials

Coagulation Factor Changes Associated With Postpartum Hysterectomies

Start date: December 2003
Phase: N/A
Study type: Observational

The purpose of this study is to examine components of the coagulation system in women undergoing postpartum hysterectomy and to compare laboratory parameters of coagulation in these women to women at increased risk for a postpartum hysterectomy, but who do not have postpartum hemorrhage and a postpartum hysterectomy. During normal pregnancy, the hemostatic balance tips toward hypercoagulation. Non-obstetric surgical blood loss is associated with increased coagulation activity. We have observed that women undergoing a postpartum hysterectomy become hypocoagulable secondary to a consumptive coagulopathy and/or excessive fibrinolysis. This coagulopathy may lead to the administration of multiple blood products. Worldwide, postpartum hemorrhage is a leading cause of maternal death. Plasma levels of tissue plasminogen activator, urokinase plasminogen activator and their inhibitors increase during pregnancy. During labor and delivery activation of coagulation occurs with consumption of platelets, coagulation factors and inhibitors. Obstetric complications during delivery can excessively activate the coagulation system and disseminated intravascular coagulation may ensue. Current treatment for postpartum coagulopathy is non-specific and primarily consists of replacing blood components. If specific causes or markers of abnormal coagulation can be identified in women at risk, then it might be possible to target (with specific medications) specific abnormalities early in the process and decrease hemorrhage and the need for blood transfusions.
