Anesthetic Management in the Precardiopulmonary Bypass Period
KEY POINTS 1. The incidence of ischemia during this period has been reported to be 7% to 56%. 2. The Society of Thoracic Surgeons recommends a cephalosporin as the primary…

KEY POINTS 1. Mechanical circulatory support devices most often are ventricular assist devices, which are indicated for bridging to myocardial recovery or cardiac transplantation or as a permanent assist device…
KEY POINTS 1. Prior to cannulation for cardiopulmonary bypass (CPB), the anesthesiologist must assure that adequate heparin-induced anticoagulation has been achieved, which is typically diagnosed as an activated clotting time…
KEY POINTS 1. The heart has a fibrous skeleton that provides an insertion site at each valvular ring. This fibrous structure also connects cardiac myocytes so that “stretch” or preload…
KEY POINTS 1. Chronic pain due to intercostal nerve injury develops in approximately 50% of postthoracotomy patients, and in 5% this pain becomes severe and disabling. 2. Thoracic epidural analgesia…
KEY POINTS 1. Core temperature (nasopharyngeal or tympanic membrane) should be greater than 36°C before terminating cardiopulmonary bypass (CPB). However, the nasopharyngeal temperature should not exceed 37°C, as this will…
KEY POINTS 1. On the day of surgery, most cardiovascular medications should be administered orally, with the exceptions of angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers, and (selectively) diuretic agents….
KEY POINTS 1. Three important channels characteristic of the circulation in utero allow preferential shunting of blood to sustain fetal viability. These include the ductus venosus, foramen ovale, and ductus…
KEY POINTS 1. Increasing utilization of intraoperative transesophageal echocardiography (TEE) has greatly expanded the role of the cardiac anesthesiologist in operations for valve repair and replacement. 2. Because atrial contraction…
KEY POINTS 1. An aortic dissection usually occurs when blood penetrates the aortic intima, forming either an expanding hematoma within the aortic wall or simply a false channel for blood…
