However, recent evidence shows that the prevalence of ischemic heart disease and cardiomyopathy is increased in transplant candidates compared to most other surgical candidates. Investigators estimate that up to 26% of all liver transplant candidates have at least one critical coronary artery stenosis and that at least half of these patients will die perioperatively of cardiac complications. Cardiomyopathy also occurs in greater frequency. While all patients with advanced cardiac disease have defects in cardiac performance, a larger than expected number of patients have classical findings of dilated, restrictive and hypertropic cardiomyopathy. This may explain why up to 56% of patients suffer from hypoxemia due to pulmonary edema following transplant surgery. There is considerable controversy on how to screen transplant candidates for the presence of heart disease. Questions focus upon, which patients should be screened and what tests should be used. This review examines screening strategies for transplant candidates and details the prognostic value of common tests used to identify ischemic heart disease. We also review the physiological consequences of cardiomyopathy in transplant candidates and explore the specific syndrome of "cirrhotic cardiomyopathy".展开更多

This rare disorder possesses potential perioperative risks, such as difficult airway management, aspiration pneumonia, hyperpyrexia, dehydration, acute renal failure, and postoperative pulmonary insufficiency. As patients were usually in the state of uncontrollable dystonia and rigidity, delayed endotracheal extubation had been suggested by several previous case reports. We report the anesthetic management of a 34-year-old Hallervorden-Spatz disease woman scheduled for intrathecal baclofen pump implantation under general anesthesia. Preoperatively she had suffered from severe dystonia, confusion and repeated attacks of respiratory insufficiency and pneumonia requiring mechanical ventilation and critical care. Anesthesia was induced uneventfully and the catheter of the pump reached the CSF via T2 interspace. Intraoperative intrathecal baclofen injection mildly relieved her severe dystonia and rigidity. Hemodynamics and arterial blood gas were improved than preoperative. She was extubated after consciousness was regained. Postanesthetic visit demonstrated a fair outcome. Whether this treatment applies to every case confronted by general anesthesia needs to be elucidated. Nevertheless, we suggest intrathecal baclofen may help postanesthetic pulmonary care by attenuating dystonia and rigidity and can be an adjuvant for anesthesia care in patients with Hallervorden-Spatz disease.展开更多
