CEREBRALANEURYSM SURGERY IN A PATIENT WITH CHRONIC RENAL FAILURE: PERIOPERATIVE CONCERNS AND CONFLICTS

Chronic renal failure (CRF) and associated multi-system abnormalities can adversely impact the outcome in patients undergoing high-risk
aneurysm surgeries by causing hemodynamic instability, uid-electrolyte imbalance, bleeding and coagulation abnormalities, decreased
anesthetic drug excretion, and dialysis-related complications. Conicts between the standard perioperative practices in aneurysm surgery and
those in CRF further contribute to the management challenges. These include, using low anesthetic drug doses but achieving good brain relaxation,
using a restrictive uid therapy but preventing postoperative vasospasm, and avoiding diuretics causing nephrotoxicity but reducing intracranial
pressure. Ayoung male with dialysis-dependent CRF and hypertension underwent emergency craniotomy and clipping of a cerebral aneurysm. He
was managed with a modied protocol of reduced heparin hemodialysis, BIS-guided use of minimum anesthetic drugs, goal-directed optimum
uid therapy, maintaining hemodynamic stability, and management of post-aneurysm clipping vasospasm with hypertension. His perioperative
management and related conicts are discussed
