Patient with Tetralogy of Fallot (TOF) may sometimes present for noncardiac surgery. These patients may have lots of other congenital anomalies, which may need repeated surgeries for their correction. Anaesthetic management in this sort of cases for noncardiac surgeries may pose a real challenge to the anaesthesiologists because of the high incidence of perioperative complications. Cyanotic spell is one among them. Cyanotic spells are usually managed by drugs. But there is report of use of non-pharmacological measures also. In this case report we present successful management of the intraoperative cyanotic spell with intravenous fluids and blood.
