Hyperbaric therapy for a postpartum patient with prolonged epidural blockade and tomographic evidence of epidural air.

Unlabelled: We used the epidural technique "loss of resistance to air" to provide labor analgesia in a healthy parturient. Inadequate analgesia required epidural catheter replacement using the same technique. Delayed recovery of sensory and motor blockade postpartum necessitated computed tomography and magnetic resonance imaging studies.

Coagulation status using thromboelastography in patients receiving warfarin prophylaxis and epidural analgesia.

To determine the coagulation status of patients receiving postoperative warfarin and epidural analgesia using thromboelastography (TEG(R)).Prospective, observational, clinical study.Orthopedic postoperative division at a university hospital.

In vitro fertilization-induced alterations in coagulation and fibrinolysis as measured by thromboelastography.

Supraphysiologic increases in estrogen produced by in vitro fertilization (IVF) promote the expression of hemostatic markers. Although quantitative studies of individual markers have been performed during IVF, their results are conflicting and do not reveal the qualitative effect of each marker on the overall coagulation and fibrinolytic processes. Thrombelastograph (TEG) coagulation analysis, by contrast, provides a global measure of coagulation and fibrinolysis and can indicate the relative contributions of clotting factors, fibrinogen, and platelets to each process.

Hemodynamics during laparoscopic surgery in pregnancy.

During laparoscopic cholecystectomy in four pregnant women, we observed hemodynamic changes similar to those in nonpregnant patients (i.e., decreases in cardiac index together with increases in mean arterial blood pressure and systemic vascular resistance).

The effect of magnesium on coagulation in parturients with preeclampsia.

Unlabelled: Preeclampsia is associated with complex coagulation abnormalities that include altered platelet function and consumption and activation of the fibrinolytic system. Magnesium sulfate, which is used as a therapeutic modality for the prevention of seizures in preeclamptic parturients, has anticoagulant and antiplatelet effects. We sought to determine the effects of magnesium on various components of the coagulation system in patients with preeclampsia.
