Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1.Comparison of effect of sevoflurane and propofol on perioperative MCA Doppler flow velocities by TCCD in patients undergoing cardiac surgery. 2.Comparison of effect of sevoflurane and propofol on perioperative ONSD in patients undergoing cardiac surgery. Timepoint: pre induction, post induction, pre CPB, on CPB, post CPB, post operatively at 6 hours and 24 hours. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Correlation between ONSD and MCA Doppler flow velocities at different time points of the perioperative period. 2. Analyse the incidence of early POCD between the two groups. 3. Correlation between ONSD, MFV in MCA, PI, ICP and CPP with the incidence of POCD. 4. Postoperative ICU requirement of sedatives or antipsychotics between the two groups. 5. Duration of mechanical ventilation, length of ICU stay and length of hospital stay between the two groups. Timepoint: TCCD and ONSD at pre induction, post induction, pre CPB, on CPB, post CPB, post operatively at 6 hours and 24 hours. Neurocognitive assessment preoperatively, postoperative day 1,2,7. | — |
