Study information
| Primary study design | Interventional |
|---|---|
| Study design | Randomised controlled trial |
| Secondary study design | Randomised controlled trial |
| Scientific title | |
| Study objectives | There is some evidence that the continuation of ACE inhibitors until the time of surgery may lead to increased requirements of vasoconstrictor agents to maintain blood pressure. We aim to investigate this suggestion. |
| Ethics approval(s) | Not provided at time of registration |
| Health condition(s) or problem(s) studied | Surgery: Cardiovascular |
| Intervention | Patients will be randomised to discontinuing their ACE inhibitor 7 days preoperatively or continuing the medication until the morning of operation. 29/08/2012: Please note that this trial was abandoned before starting. |
| Intervention type | Drug |
| Phase | Not Specified |
| Drug / device / biological / vaccine name(s) | Angiotensin Converting Enzyme (ACE) Inhibitor |
| Primary outcome measure(s) |
Primary outcome measures are those relating to the presence and treatment of perioperative and postoperative hypotension. Systemic vascular resistance will be measured via Swan-Ganz catheterisation preoperatively and at fixed intervals in the postoperative period. In addition the requirement of vasoconstrictor agents as well as the duration of their use and the total dose administered will be documented. |
| Key secondary outcome measure(s) |
