Autonomic Cardiovascular Control for Elderly Surgery Patients
Studieöversikt
Detaljerad beskrivning
Patients admitted for elective, major, abdominal surgery will be tested with a head-up tilting to 20 degrees for 15 minutes preoperatively and again on the second postoperative day. Haemodynamic variables will be registered by the device TaskForceMonitor which monitors heart rate (HR), electrocardiography (ECG), blood pressure and stroke volume continuously and non-invasively.
Background variables (including demographics, comorbidity and simple cognitive tests) and daily variables (including delirium assessments) will be registered.
Blood and saliva samples will be drawn preoperatively and postoperatively to measure levels of stress hormones and inflammatory markers.

Change in orthostatic cardiovascular responses
Tidsram: Baseline and postoperatively at surgical ward (expected second postoperative day)
|
Change in orthostatic cardiovascular responses (head-up tilt test) pre- and postoperatively in patients with and without postoperative delirium will be evaluated based on measurements of heart rate, systolic blood pressure (BP), mean BP, diastolic BP, stroke index, total peripheral resistance index, end-diastolic volume index, and acceleration index.
