Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To compare intraoperative distal MCA cerebral blood flow velocities in Moya Moya Disease patients receiving Ioflurane, Sevoflurane, Desflurane, Propofol anaesthesia during direct revascularisation (STA-MCA Bypass) surgery.Timepoint: Preanastomosis and post anastomosis | — |
Secondary
| Measure | Time frame |
|---|---|
| To observe the changes in the distal MCA mean blood flow volume before & after micro-anastomosis under different anaesthesia. To compare the intraoperative mean distal MCA CBFV changes during hypercapnia prior to & during hypocapnia after micro anastomosis. To compare the changes in mean distal MCA CBFV following blood pressure augmentation after anastomosis & correlation with post-operative hyperaemic complications. To observe the changes in regional cerebral oxygenation (rSO2) before & after anastomosis & correlation with post-operative ischemic & hyperaemic complications. Timepoint: Hypercapnea-Before hypercapnia & at 5 min after achieving hypercapnia Hypocapnia-Before hypocapnia & at 5 min after achieving hypocapnia BP augmentation-Before BP augmentation and at 5 min after desired increase in MAP being achieved Cerebral oximetery-Before & after anastomosis Baseline, Post intubation, post hypercapnic challenge, post hypocapnic challenge, post hypertensive challenge, Post clamping, Post Anastomosis , Surgery end & Before reversal | — |
