Terlipresina como tratamiento de rescate de las crisis hipoxémicas en la tetralogía de fallot

Terlipressin as rescue therapy in hypercyanotic spells of fallot tetralogy Abstract Hypercyanotic spells, very common in Fallot tetralogy, are a medical emergency and can cause neurological damage or even death. They are produced by a dramatic decrease in pulmonary blood flow, with increased right-left shunt and a drop in systemic arterial saturation. Treatment includes a.-agonists (such as methoxamine or phenylephrine), which increase peripheral resistance, forcing the entry of blood through the infundibulum.
