Heparin Solution and INTEM/HEPTEM Analysis

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.

Treatment and study plan

Heparin

Drug

Heparinized flush solution contained heparin concentration of 2 unit/ml and continuous flow of the flush solution was 5 ml/h at 300 mmHg.

Primary outcomes

  1. INTEM test

    Time frame: 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.

  2. HEPTEM test

    Time frame: 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. 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.

Secondary outcomes

  1. Total infused units of heparin

    Time frame: periond from starting operation to finishing operation (espected average of 5 hours).
