Studies of Left Atrial Pressure during Cardioplegia Produced by Profound Hypothermia Using the Closed Chest Technique.
نویسندگان
چکیده
Profound hypothermia can be induced and reversed with safety without opening the chest when a heart/lung machine is used (Woodhall, Sealy, Hall, and Floyd, 1960; Patterson and Ray, 1962). Blood is drained into the heart/lung machine from an external iliac vein and, after being oxygenated and cooled or warmed as the case may be, is returned to the body through an external iliac artery (Fig. 1). During cooling, ventricular fibrillation almost always occurs, but this can be reversed externally during rewarming. When the temperature is sufficiently low, it is possible to arrest the circulation completely for long

Mechanisms determining the behaviour of the left atrial pressure during cardioplegia.
The technique of inducing profound hypothermia by peripheral cannulation in man without opening the chest and using a heart-lung machine does not permit the surgeon to vent the left side of the heart (Woodhall, Sealy, Hall, and Floyd, 1960; Patterson and Ray, 1962). In open-heart surgery this is considered to be a vital step in preventing dilatation of the left heart and the pulmonary vasculatu...
متن کاملClosed-chest circulatory support by pump-oxygenator in experimental ventricular fibrillation at normal temperature.
Interest is growing in the use of closed-chest circulatory support via peripheral cannulation, using pumps or pump-oxygenators, both in emergencies encountered during the post-operative period following intracardiac surgery (Spencer, Eiseman, Trinkle, and Rossi, 1965) and electively in intracranial surgery using profound hypothermia and cardiac arrest (Woodhall, Sealy, Hall, and Floyd, 1960; Mi...

Introduction & Objective: The role of free radicals in reperfusion injury has been revealed in the previous studies. Protective effects of endogenic antioxidants include glutathione has been shown in cardiomyocyte. Intracellular L-cysteine availability is one of the major rate limiting factors in glutathione production. This study aimed to investigate the role of L-cysteine in the preservation ...
متن کاملCardiac operation without hypothermia for the patient with cold agglutinin.
Recently, a new technique for myocardial protection that does not rely on hypothermia has been reported. In this method, the heart is continuously perfused with normothermic hyperkalemic blood cardioplegia during the cross-clamp period. Cardiac arrest is achieved and maintained using high levels of potassium. Hypothermia is not part of this technique; thus, the danger of hypothermia can be avoi...
متن کاملA Semi-Automated Algorithm for Segmentation of the Left Atrial Appendage Landing Zone: Application in Left Atrial Appendage Occlusion Procedures
Background: Mechanical occlusion of the Left atrial appendage (LAA) using a purpose-built device has emerged as an effective prophylactic treatment in patients with atrial fibrillation at risk of stroke and a contraindication for anticoagulation. A crucial step in procedural planning is the choice of the device size. This is currently based on the manual analysis of the “Device Landing Zone” fr...
