Hemodynamic Instability
Conditions
Brief summary
This trial investigates the ability of our istitutional algorithm in maintaining a safe hemodynamics during abdominal aorta open surgery, in terms of limitation of intraoperative hypotension incidence
Detailed description
The present trial includes patients submitted to abdominal aorta open surgery. This type of procedure is very challenging for the hemodynamic management because of the operation per se (during which the surgeon clamp and unclamp the aorta with very significant hemodynamic variations) and because of the altered tone of the vessels due to the general vascular disease such a type of patients is suffering from. The aim of this study is to verify if the incidence of intraoperative hypotension in terms of severity, lasting and number of episodes, may be reduced by the application of a protocol of hemodynamic management. Primary endpoint: Global time spent in hypotension \<10%. Secondary Endpoints: 1. Time Weighted Average (TWA) of Area Under the Threshold \<0.4 mmHg 2. Incidence of hypotensive events/patient \< 8 (including the expected hypotensive events due to the aortic clamping and unclamping)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Global time spent in hypotension <10% | Intraoperative period | Hypotension=mean arterial pressure \<65 mmHg for at least 1 minute |
Secondary

|---|---|---|
| Time Weighted Average (TWA) of Area Under the Threshold <0.4 mmHg | Intraoperative period | The severity of hypotension during the whole intraoperative surgery |
| Incidence of hypotensive events/patient < 8 | Intraoperative period | including the expected hypotensive events due to the aortic clamping and unclamping |
