Brief summary
The purpose of this study is to evaluate the ability of vascular occlusion test (VOT) during cardiac surgery to predict postoperative outcomes in pediatric patients.
Detailed description
After induction of anesthesia, pediatric SomaSensor for INVOS 5100C is attached at calf muscle and non-invasive blood pressure cuff is applied to ipsilateral thigh. VOT is performed as: after baseline oxygen saturation value is recorded, cuff pressure is rapidly increased to 30 mmHg over than systolic blood pressure. After 3 minutes of ischemic time, cuff pressure is rapidly decreased. It is performed at 3 time periods : before start of operation, during cardiopulmonary bypass, and after weaning from cardiopulmonary bypass. Postoperative outcome variables are recorded after surgery : major adverse event, use of inotropic and vasoactive drugs, duration of mechanical ventilation and ICU stay. The relationship between the results of VOT and postoperative outcome will be investigated.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Major adverse event | up to 1 years after surgery | Major adverse event is defined as cardiac compression, re-sternotomy because of hemodynamic instability, ECMO support, Cr\> 2mg/dL, cerebral hemorrhage or infarct and mortality. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Use of inotropic and vasoactive drugs | up to 1 years after surgery | Use of inotropic and vasoactive drugs is evaluated using vasoactive-Inotropic scores (VIS). VIS is calculated as: dopamine dose (㎍/kg/min) + dobutamine dose (㎍/kg/min) + 100 x epinephrine dose (㎍/kg/min) + 10 x milrinone dose (㎍/kg/min) + 10,000 x vasopressin dose (U/kg/min) + 100 x norepinephrine dose (㎍/kg/min).(7) VIS at 0, 24, 48, and 72 hours after surgery ended are collected in all patients. |
| Length of mechanical ventilation time and ICU stay | up to 1 years after surgery | — |
