Secondary
| Measure | Time frame | Description |
|---|---|---|
| diameter of superficial temporal artery and radial artery measured by a high resolution ultrasound scanner, C-scan | in-hospital 2 h. | changes from base line recorded every 10th min. until time 90 min on day 1 and day 2. The infusion takes 25 min from time 0. |
| mean arterial blood pressure (MAP), heart rate (HR), end-tidal partial pressure of pCO2 (PetCO2), transcutaneous arterial oxygen saturation (SAT) measured by ProPac Encore® | in-hospital 2 h. | changes from base line recorded every 10th min. until time 90 min on day 1 and day 2. The infusion takes 25 min from time 0. |
| Blood flow velocity in the middle cerebral artery (VMCA) measured by a Transcranial Doppler (TCD) ultrasonography (2MHz) | in-hospital 2 h. | changes from base line recorded every 10th min. until time 90 min on day 1 and day 2. The infusion takes 25 min from time 0. |
