Harmful effect of epinephrine on postreperfusion syndrome in an elderly liver transplantation recipient with sigmoid ventricular septum: A case report.

Introduction: As a common morphological change of aging heart, sigmoid ventricular septum is frequently found during routine preoperative evaluation, but often disregarded because of its little clinical importance. However, in this report, we describe a 70-year old patient with sigmoid ventricular septum who developed severe hemodynamic deterioration during liver transplantation because of its unique morphology of heart.

Methods: During the course of reperfusion of the graft, patient's hemodynamics were closely monitored using transesophageal echocardiography.

Usefulness of intraoperative bronchoscopy during surgical repair of a congenital cardiac anomaly with possible airway obstruction: three cases report.

Compression of the airway is relatively common in pediatric patients, although it is often an unrecognized complication of congenital cardiac and aortic arch anomalies. Aortopexy has been established as a surgical treatment for tracheobronchial obstruction associated with vascular anomaly, aortic arch anomaly, esophageal atresia, and tracheoesophageal fistula. The tissue-to-tissue arch repair technique could result in severe airway complication such as compression of the left main bronchus which was not a problem before the correction.

Hemolysis of irradiated leukoreduced red blood cells during rapid warming: An experimental study.

Background: Although water chambers are often used as surrogate blood-warming devices to facilitate rapid warming of red blood cells (RBCs), these cells may be damaged if overheated. Moreover, filtered and irradiated RBCs may be damaged during the warming process, resulting in excessive hemolysis and extracellular potassium release.

Methods: Using hand-held syringes, each unit of irradiated and leukocyte-filtered RBCs was rapidly passed through a water chamber set to different temperatures (baseline before blood warming, 50℃, 60℃, and 70℃).
