In anaesthesia and surgery, perfusion of an extensive, previously ischaemic vascular bed triggers the release into the circulation of large quantities of potassium resulting from the outflow of intra-cellular potassium, due to disrupted membrane pumps from local acidosis.
En anestesia y cirugía la perfusión de un lecho vascular extenso previamente isquémico produce liberación a la circulación de grandes cantidades de potasio generadas por la salida de potasio intracelular a causa de la acidosis local que altera las bombas de membrana.
