Brain Tumor, Cerebral Artery Anuerysm, Spinal Stenosis
Conditions
Brief summary
Heparinized solution has been used for maintenance of arterial catheter during perioperative period. Although the infused dose of heparin is very low, the investigators examine whether the heparin effect is remained or not in blood using rotational thromboelastometry (ROTEM) analysis.
Interventions
Heparinized flush solution contained heparin concentration of 2 unit/ml and continuous flow of the flush solution was 5 ml/h at 300 mmHg.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| INTEM test | at 30 min before operation and 30 min after operation | INTEM is not an abbriviation. INTEM is one of the ROTEM test and it is an coagulation test name (such as prothrombin time test) using patient's whole blood. We put the blood sample of patinet into the machine, so the result comes out automatically. It will be checked twice at pre- and postopertive 30 minute and it'll be analyzed and compared. |
| HEPTEM test | at 30 min before operation and 30 min after operation | HEPTEM is not an abbriviation. HEPTEM is one of the ROTEM test and it is an coagulation test name (such as prothrombin time test) using patient's whole blood.
