RESUMEN
Anaesthesia for aneurysm surgeries is highly specialized and unique. Vasospasm is the most important determinant for morbidity and mortality in intracranial aneurysms. For prevention and management of vasospasm Triple-H therapy (Hypertension, Hypervolemia and Haemodilution) is recommended. Triple-H therapy is gold standard in neuroanaesthesia in intracranial aneurysm surgeries in order to increase cerebral blood flow in areas affected by vasospasm and avoid damage caused by ischemia. First patient was 52 years old female with Right vertebral artery posterior inferior cerebellar artery aneurysm of size 1cm, operated successfully who became unconscious 22 hours after surgery and treated with Triple-H therapy for vasospasm. Second case was 48 years old male patient of right anterior cerebral artery aneurysm of 9mm size operated successfully after intraoperative rupture of aneurysm and subsequent vasospasm. Third case was 35 years pregnant female patient of anterior communicating artery aneurysm of 5mm size treated with triple H therapy for vasospasm.
