Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Remifentanil | Following an intravenous bolus dose of 0.5 µg/kg remifentanil administered just before the induction of anaesthesia, patients will receive an intravenous infusion of remifentanil at a dose of 0.25-0.5 µg/kg/min throughout the surgery. The rate of infusion will be adjusted to maintain a mean blood pressure within %70-80 of the baseline value. At the end of the surgery, the rate of infusion will be decreased to 0.05 µg/kg/min, and continued until the patient is extubated. | 21 | 44 | EG000 |
| Group 2 | Tramadol + Metoprolol | Just before the induction of anaesthesia, an intravenous infusion of 1 mg/kg of tramadol in 100 ml isotonic fluid will be started. The infusion will be completed in 30 minutes using a perfusor. Additionally, following the administration of the neuromuscular blocking agent, 0.1 mg/kg of intravenous metoprolol will be administered within 5 minutes. | 0 | 44 | EG001 |
