Repeated Circulatory Arrest under Hypothermia

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...

Repair 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...

Perfusion 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...

Rewarming from severe accidental hypothermia with circulatory arrest.

This case report demonstrates successful cardiopulmonary and cerebral resuscitation (CPCR) of a young male explored 15 hours following a suicide attempt (carbamazepine intoxication) in deep hypothermia (19 degrees C) with circulatory arrest. An extracorporeal circuit was used to rewarm the patient's blood. Weaning from extracorporeal circulation (ECC) was successful and without complications as...
