Platelet rich plasma (PRP) is being used with increased frequency in many surgical procedures for its known benefits of accelerated surgical wound site healing. Speculations in its efficacy in the presence of anti-platelet therapy have been proposed. To aid in defining a quality platelet rich plasma product in the presence of acetylsalicylic acid (ASA) and Plavix (clopidogrel bisulfate), we investigated three (3) groups (n = 18) of cardiac surgical patients receiving PRP. Platelet function test, platelet concentration, and quantification of growth factors (PDGF-bb and TGF-b1) were evaluated. Results showed no statistical evidence of decreased growth factors delivered to the surgical wound site in the presence of acetylsalicylic acid (ASA) and/or Plavix (clopidogrel bisulfate). Evidence in this pilot study supports the use of PRP for patients receiving Plavix and aspirin therapy without compromising the quantity of specific growth factors delivered to a wound site.
Embolization of marrow fat appears to be an inevitable consequence of long bone fractures. Pulmonary fat embolism (FE) with cardiovascular collapse is associated with a high mortality rate because of acute right ventricular failure and hypoxia. Immediate and appropriate resuscitation is required to prevent sudden death. Although extracorporeal membrane oxygenation (ECMO) has been used for a multitude of applications involving respiratory and circulatory collapse, its full potential as a standard conventional therapy has yet to be exploited. Herein, we describe the successful use of veno-venous (V-V) ECMO in a trauma patient who initially presented with fractures of the right ulna and femur. After surgery, the patient rapidly decompensated despite massive ventilatory support and was placed on ECMO. ECMO support lasted approximately 120 hours followed by an uneventful recovery and discharge 10 days later.
Heparin-induced thrombocytopenia and its related complications can be life-threatening in patients undergoing cardiopulmonary bypass (CPB) with heparin exposure. While the literature illustrates many different techniques which might be employed in this situation, most are used infrequently. This case report provides an overview of the successful use of r-Hirudin, and associated monitoring techniques, in a high-risk patient undergoing cardiac surgery utilizing CPB.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
