Since the first report of clonidine, an alpha2-adrenoceptor agonist, the indications for this class of drugs have continued to expand. In December 1999, dexmedetomidine was approved as the most recent agent in this group and was introduced into clinical practice as a short-term sedative (<24 hours). Alpha2-adrenoceptor agonists have several beneficial(More)
OBJECTIVE Although the lysine analogs tranexamic acid (TXA) and aminocaproic acid (EACA) are used widely for antifibrinolytic therapy in cardiac surgery, relatively little research has been performed on their safety profiles, especially in the setting of cardiac surgery. Two antifibrinolytic protocols using either TXA or aminocaproic acid were compared(More)
BACKGROUND Perioperative acquired factor XIII deficiency has been looked upon as a potential cause of postoperative bleeding in adult cardiac surgery. METHODS Forty-four infants were prospectively studied for the time course of factor XIII in plasma and the effect on chest tube drainage (CTD) and transfusion requirements in the first 24 h after surgery. A(More)
BACKGROUND Concerns of increased cardiovascular (CV) thromboembolic adverse effects from nonsteroidal antiinflammatory drugs (NSAIDs, both nonselective [NS]-NSAIDs and cyclooxygenase [COX]-2 selective inhibitors) have prevented their use despite numerous benefits. METHODS In this descriptive review, we critically examine the randomized, active- and(More)
BACKGROUND With the withdrawal of aprotinin from worldwide marketing in November 2007, many institutions treating patients at high risk for hyperfibrinolysis had to update their therapeutic protocols. At our institution, the standard was switched from aprotinin to ε-aminocaproic acid (EACA) in all patients undergoing cardiac surgery with extracorporeal(More)
BACKGROUND ε-Aminocaproic acid (EACA) and tranexamic acid (TXA) are used for antifibrinolytic therapy in neonates undergoing cardiac surgery, although data directly comparing their blood-sparing efficacy are not yet available. We compared two consecutive cohorts of neonates for the effect of these two medications on perioperative blood loss and allogeneic(More)
OBJECTIVES To evaluate the in vitro effects of high concentrations of heparin and its reversal with protamine on routine laboratory parameters as well as on modified thromboelastogram (ROTEM; TEM International, Munich, Germany) and impedance aggregometry (MULTIPLATE; Dynabyte, Munich, Germany). DESIGN An observational, nonrandomized in vitro study. (More)
OBJECTIVE Tranexamic acid (TXA) and ɛ-aminocaproic acid (EACA) are used for antifibrinolytic therapy in cardiac surgery, although data directly comparing their blood sparing effect and their side effects, especially in paediatric cardiac surgical patients, are still missing. METHODS We analysed perioperative data of 234 paediatric patients weighing less(More)
BACKGROUND Once aprotinin was no longer available for clinical use, ε-aminocaproic acid (EACA) and tranexamic acid became the only two options for antifibrinolytic therapy. We compared aprotinin and EACA with respect to their blood-sparing efficacy and other major clinical outcome criteria in infants undergoing cardiac surgery. METHODS We retrospectively(More)
