ABSTRACT
Anesthesia for cardiac surgical patients with antiphospholipid antibody syndrome (APLS) presents challenges with monitoring anticoagulation during cardiopulmonary bypass. Additionally, this condition is associated with other autoimmune diseases and comorbidities that need to be considered in caring for these patients, and there is minimal evidence for specific strategies during cardiac surgery. Separately, Jehovah's Witness (JW) patients typically do not consent to receiving blood products, presenting an additional challenge for resuscitation during cardiac surgery and especially in the context of APLS. We present our approach to the anesthetic management of a JW patient with systemic lupus erythematosus (SLE) complicated by APLS, thrombocytopenia, and renal failure with history of renal transplant who presented for coronary artery bypass surgery. Management strategies we recommend include administration of antifibrinolytics after heparinization to mitigate bleeding risk and interdisciplinary management with the perfusion, intensive care, surgical, and nephrology teams.
ABSTRACT
AN APPRECIATION of the utility of echocardiographic Doppler spectral profile analysis in diagnosing cardiac pathology and guiding surgical intervention more than justifies an investment in obtaining proficiency in these skills. Given the relatively low incidence of significant complications associated with transesophageal echocardiographic examination, the facile use of both spectral and color Doppler principles to diagnose unusual pathology is essential. Doppler modalities are used to characterize blood flow, pressure gradients, chamber dimensions, and other anatomic and physiological parameters. The authors present a case in which several Doppler principles were used to evaluate and diagnose the etiology of dyspnea and a high aortic valve gradient.
