Patients undergoing surgery in beach chair position (BCP) are at risk for cerebral ischaemia. The impacts of arginine vasopressin (AVP) on haemodynamics and cerebral oxygenation are evaluated during surgery in BCP.
Patients undergoing shoulder surgery in BCP under general anaesthesia are randomly allocated to receive i.v. normal saline (control group) or AVP 0.05 or 0.07 U kg-1 (AVP group, n = 15 each) 2 min before moving into BCP. Mean arterial pressure (MAP), heart rate (HR), jugular venous bulb oxygen saturation (SjvO2) and regional cerebral tissue oxygen saturation (SctO2) are measured before (pre-sitting in supine position) and after patients assumed BCP.

| Measure | Description | Time Frame |
|---|---|---|
| Jugular venous oxygen desaturation | Jugular venous oxygen saturation is continuously measured whether its saturation is decreased below 50% or/and 40% for longer than 5 min. | Up to 30 min after the positioning |
| Measure | Description | Time Frame |
|---|---|---|
| Cerebral oxygen desaturation | Continuously observe near-infrared spectroscopy measured cerebral oxygenation before and after beach chair position whether oxygen saturation decrease more than 20% from pre-sitting values | Up to 30 min after the position change |
