Emergencies in CPB• Massive Air Embolism• Aortic Dissection with cannulation• Clotted Oxygenator• Severe Protamine Reaction• Inadequate CPB flow• Inadequate CPB oxygenation
Massive Air Embolism• Recognition• Stop CPB• Place pt in steep head-down position• Remove aortic cannula from asc. Aorta• Purge asc. aorta of air and refill arterial line• Begin retrograde SVC perfusion (20C@1-2l/min for 2-3min until air is cleared• Return cannula to aorta for systemic cooling and?pharmacologic brain protection• Post-op-Hyperbaric O 2 rx, hyperventilation, ?hypertension
