Filter by:This study compares the effect of starting intravenous oxytocin infusion early before uterine incision versus late after umbilical cord clamping on the blood loss during elective cesarean section
Cesarean delivery has become the most common surgical procedure in the US. Non-steroidal anti-inflammatory drugs (NSAIDs) have been shown to improve the quality of post-cesarean analgesia and markedly reduce opioid consumption. The effect of NSAIDs on healthy volunteers results in inhibition of platelet aggregation and prolonged bleeding time. However, in the obstetric population, the presence and degree of platelet inhibition after NSAID exposure is less clear. The investigators plan to use Platelet Aggregometry and Thromboelastography (TEG) to evaluate the effect of ketorolac on platelets.
Up to 15% of operations in cardio-pulmonary by-pass are complicated by excessive postoperative blood loss, which negatively affects the outcomes. Recently, it has been demonstrated that fibrin clot susceptibility to lysis is a modulator of postoperative blood loss after cardiac surgery for aortic stenosis. Earlier, a preliminary study showed a negative association of postoperative blood loss after coronary artery by-pass grafting (CABG) with fibrin clot lysis time, reflecting susceptibility to fibrinolysis. In CABG, postoperative blood loss may depend on the operative technique with respect to left internal mammary artery (LIMA) harvesting. LIMA is taken down in virtually all CABG procedures, but harvesting technical details remain at surgeons discretion (skeletonization without opening the pleural cavity vs. pedicled graft with pleura wide open). The investigators decided to test the hypothesis that fibrin clot properties modulate the postoperative drainage following CABG strongly enough to attenuate the influence of surgical technique by randomizing the patients undergoing CABG with regard to LIMA harvesting technique.
This study evaluates the hemostatic changes defined as hemostasis reserve capacity (HRC) in the first perioperative 48 hours of bloodless liver transplanted patients.
Estimated blood loss is an important parameter recognized as a standard practice in anesthesiology and others medical specialties, with relevant clinical and research applications. Currently is no model capable of accurately estimate blood loss. The purpose of this study is to evaluate the accuracy of a novel model.
In this randomized, double-blind control trial to evaluate the effect of ketorolac given at the time of cord clamp has on estimated blood loss and postcesarean pain control. Patients will be randomized to either placebo or ketorolac prior to surgery. Those randomized to ketorolac will receive ketorolac at cord clamp and three additional doses every 6 hours (total 4 doses/24 hours). Those in the placebo group will receive normal saline during those time periods. Our primary outcome is to assess whether intra-operative ketorolac increases the estimated blood loss during Cesarean delivery.
The purpose of this research is to determine if the oral form of a medication (tranexamic acid) to reduce bleeding can be used in place of an intravenous (IV) form, to learn the best way to give tranexamic acid: either a pill by mouth, or a solution by vein.
