Effect of thoracic epidural blockade on hypoxia-induced pulmonary arterial hypertension in rats
Objective(s): The present study was aimed to investigate the influence of thoracic epidural blockade on hypoxia-induced pulmonary hypertension in rats. Materials and Methods: Forty eight Wistar rats were randomly divided into 4 equal groups, named normoxia hypoxia hypoxia/ ropivacaine and hypoxia/saline. Animals were placed in a hypoxia chamber and instrumented with epidural catheters at the t...

متن کاملSurgery for multiple and diffuse pulmonary arteriovenous fistulas during childhood.
We report an uncommon clinical case of multiple, diffuse pulmonary arteriovenous fistulas that occurred during childhood. A 15-year-old Japanese girl with multiple pulmonary arteriovenous fistulas presented with moderate hypoxemia and was treated by left lower lobectomy for complete resection of the arteriovenous fistulas. Clinical and radiographic features are presented.
متن کاملBosentan prevents hypoxia-reoxygenation-induced pulmonary hypertension and improves pulmonary function.
BACKGROUND Acute hypoxia results in increased pulmonary vascular resistance. Despite reoxygenation, pulmonary vascular resistance remains elevated and pulmonary function is altered. Endothelin-1 might contribute to hypoxia-reoxygenation-induced pulmonary hypertension and to reoxygenation injury by stimulating leukocytes. This study was carried out using an established model of hypoxia and reoxy...
