Study information
| Primary study design | Interventional |
|---|---|
| Study design | Randomised controlled trial |
| Secondary study design | Randomised controlled trial |
| Scientific title | |
| Study objectives | We aimed to investigate the effect of oxygen delivery index (DO2I) optimisation with fluids versus with fluids and dobutamine on 60-day hospital mortality and incidence of complications. |
| Ethics approval(s) | Ethics approval received from the local medical ethics board on the 13th May 2002 (ref: 2611/2002). |
| Health condition(s) or problem(s) studied | High-risk patients undergoing prolonged surgery |
| Intervention | Therapy consisted of pulmonary artery catheter (PAC)-guided haemodynamic optimisation during the operation and 24 hours postoperatively, using either fluids alone or fluids and dobutamine with the aim of achieving supranormal values (oxygen delivery index [DO2I] greater than 600 ml/min/m^2). |
| Intervention type | Drug |
| Phase | Not Specified |
| Drug / device / biological / vaccine name(s) | Dobutamine |
| Primary outcome measure(s) |
To evaluate the effect of both DO2I optimisation with fluids compared to with fluids and dobutamine on 60-day mortality in high-risk general surgery patients. |
| Key secondary outcome measure(s) |
The incidence of complications, particularly adverse cardiovascular events. |
