Effect of Goal-directed Fluid Therapy Based on Stroke Volume Variation on Metabolic Acidosis in Patients Undergoing Brain Tumor Surgery
In patients undergoing craniotomy, 0.9% normal saline is commonly administered in order to reduce cerebral edema. Excessive administration of 0.9% normal saline has been to reported to cause hyperchloremic metabolic acidosis. On the other hand, hypovolemia due to insufficient fluid replacement for perioperative loss can also result in metabolic acidosis by lactic acid accumulation. However, the guideline for perioperative fluid management has not been yet established. The investigators hypothesized that intraoperative fluid management according to SVV(Stroke Volume Variation)could reduce perioperative metabolic acidosis compared to those by CVP(Central Venous Pressure). Therefore, the study is trying to determine if intraoperative fluid administration based on SVV could reduce metabolic acidosis when compared with CVP in patients undergoing craniotomy due to brain tumor who receive 0.9% normal saline as main fluid regimen.

Masking: Double Blind (Subject, Outcomes Assessor)
Primary Purpose: Supportive Care
- Standard base excess point [ Time Frame: at the suturing of scalp ] [ Designated as safety issue: No ]
|Study Start Date:||December 2012|
|Estimated Study Completion Date:||July 2014|

Active Comparator: group C
intraoperative fluid management based on CVP
Patients in group C receive additional fluids (400 ml of normal saline or 200 ml of colloid) when CVP is less 8 during the surgery.
Experimental: group S
intraoperative fluid management based on SVV
During the surgery, patients in group S receive additional fluids (400 ml of normal saline or 200 ml of colloid) when SVV is less than 13.
