Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To determine the efficacy of goal-directed heart rate control to attenuate cardiac troponin plasma level elevation after non-cardiac surgery using the ultra-short acting ß-blocker esmolol during emergence from anesthesia and during post-anesthesia care.;Secondary Objective: To determine the feasibility of goal-directed heart rate control using the ultra-short acting ß-blocker esmolol.;Primary end point(s): Myocardial injury measured as the peak postoperative hs-cTnT.;Timepoint(s) of evaluation of this end point: After surgery until postoperative day 3 | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Mean heart rate;Timepoint(s) of evaluation of this end point: During anesthesia and at PACU | — |
