Protective Hypothermia During Brain Surgery

A multicenter clinical study is being conducted comparing the use of hypothermia with conventional cooling blankets in the surgical repair of unruptured intracranial aneurysms. Mild-to-moderate hypothermia is used by many neurosurgeons to protect the brain during cerebrovascular surgery and is commonly induced by the use of cooling blankets and other body surface cooling devices.

The cooling system being used in the study is the Celsius Control System from Innercool Therapies, Inc. (San Diego, CA, USA). The system uses an intravascular catheter and control system that exchanges heat directly with the blood flowing in the vessels of the body. The catheter is introduced in the same manner as other central venous catheters. The system does not require fluids to be perfused into the body, nor does it require blood to be circulated outside the body.

"We have had a very positive experience using the Celsius Control System,” said Gary K. Steinberg, M.D., professor and chairman of neurosurgery at Stanford University School of Medicine (Palo Alto, CA, USA). "We see other clinical opportunities evolving from this novel technology.”
