Norway30 participantsStarted 2022-10-18

Plain-language summary

The investigators will perform a clinical observational study of patients undergoing abdominal surgery. The study will be performed at Sykehuset Telemark, Skien. The aims of the study are to compare suprasternal and transoesophageal Doppler (reference method) to measure blood flow in the proximal descending aorta and to explore the variability of hemodynamic variables during surgery.
