Biochemical changes during circulatory arrest under deep hypothermia.
At body temperatures between 100 C. and 150 C. complete circulatory arrest is relatively safe for periods of 60 minutes or more, giving time for extensive open heart operations. The clinical use of this procedure has far outstripped its full investigation under controlled conditions. The time limit for arrest at any given temperature is not known, nor are the types of damage which will occur at...
متن کاملBleeding following deep hypothermia and circulatory arrest in children.
Deep hypothermic circulatory arrest (DHCA) is a technique of extracorporeal circulation commonly used in children with complex congenital heart defects undergoing surgical repairs. The use of profound cooling (20 degrees C) and complete cessation of circulation allow adequate exposure and correction of these complex lesions, with enhanced cerebral protection. However, the profound physiologic s...
متن کاملElectrocardiographic changes during hypothermia and circulatory occlusion.
An analysis of the electrocardiograms from 25 patients during reduction of body temperature and total occlusion of circulation reveals marked abnormalities in conduction and rhythmicity. Hypothermia was accompanied by slowing of the heart rate, depression of intracardiac conductivity, and by inhibition of the normal centers of impulse formation with resultant atrial arrhythmias. Circulatory occ...
متن کاملRepair of traumatic aortic arch to innominate vein fistula under deep hypothermia and circulatory arrest.
Penetrating injuries of the thoracic aorta are usually rapidly lethal. Few patients survive for long enough to undergo surgical treatment. When penetrating injuries of the thoracic aorta are complicated by arteriovenous fistula a correct preoperative diagnosis is important for adequate planning of the surgical repair, and so selective angiography is essential. The best approach is through a med...
متن کاملPerfusion techniques for pulmonary thromboendarterectomy under deep hypothermia circulatory arrest: a case series.
Pulmonary thromboendarterectomy (PTE) is a complicated surgical procedure that is an effective treatment in reducing pulmonary artery pressure and pulmonary vascular resistance for chronic thromboembolic pulmonary hypertension. Chronic thromboembolic pulmonary hypertension usually results from incomplete lysis of a large organized thrombus in the main pulmonary artery and secondary branches, le...
