The Use of Regional or Local Anesthesia for Carotid Endarterectomies May Reduce Blood Loss and Pulmonary Complications.
Over 150,000 carotid endarterectomy (CEA) procedures are performed each year. Perioperative anesthetic management may be complex due to multiple patient and procedure-related risk factors. The authorsaimed to determine whether the use of general anesthesia (GA), when compared with regional anesthesia (RA), would be associated with reduced perioperative morbidity and mortality in patients undergoing a CEA. ⋯ The use of RA over GA in CEA is associated with decreased risk of postoperative pneumonia and a reduced need for perioperative blood transfusions.

Case ReportsThe Use of Cangrelor and Heparin for Anticoagulation in a Patient Requiring Pulmonary Thromboendarterectomy Surgery with Suspected Heparin-Induced Thrombocytopenia.
The management of heparin-induced thrombocytopenia (HIT) in the perioperative period for patients undergoing cardiac surgery requiring cardiopulmonary bypass (CPB) and deep hypothermic circulatory arrest (DHCA) can be a challenging clinical scenario. Once a diagnosis of HIT has been established, heparin products typically are avoided and alternative therapies for anticoagulation are started. Alternative anticoagulation strategies for CPB are limited and often have various pharmacokinetic profiles that may lead to increased perioperative bleeding. ⋯ The authors hypothesized that cangrelor would reduce the risk of significant bleeding compared with tirofiban because of its favorable pharmacokinetics. Specifically, cangrelor has a short elimination half-life of 3 to 6 minutes, and its elimination is not altered by renal and hepatic impairment. This case report discusses the pathophysiology of HIT, the alternative anticoagulants used for HIT type II in pulmonary thromboendarterectomy, and the potential of cangrelor in conjunction with UFH to be a favorable option for patients in similar clinical scenarios.
