tetralogy of Fallot anesthetic implications
Pronunciation: teh-TRAL-oh-jee of fah-LOW
Special anesthetic considerations for patients with TOF, including shunt management, hypercyanotic spells, and hemodynamic monitoring requirements.
Full Definition
Complex anesthetic management principles for patients with tetralogy of Fallot, the most common cyanotic congenital heart disease. Key considerations include understanding the pathophysiology of right ventricular outflow obstruction, ventricular septal defect, aortic override, and right ventricular hypertrophy. Anesthetic goals focus on maintaining systemic vascular resistance, avoiding increases in pulmonary vascular resistance, preventing air embolism through meticulous IV line management, and being prepared to manage hypercyanotic spells with positioning, volume, and systemic vasoconstrictors.
Usage
Usage note: Requires specialized cardiac anesthesia knowledge; complex hemodynamic considerations
