• 7.5ml/100g/min

• 10ml/100g/min

All the following happens during ischemic brain injury EXCEPT

• Anerobic glycolysis

• Decreased Na-K ATPase activity

• Decreased Excitotoxicity

• cellular edema

Safe duration of DHCA at 18 degrees

• 10 - 25 mins

• 30 - 45 mins

• 60 -75 mins

• 80-100 mins

One of the hydroxy free radical scavenger which reduces cerebral edema

• Furosemide

• Thiopentone

• Mannitol

• Bicarbonate

The ideal pH management strategy to follow during DHCA is

• pH stat

• α –stat

• pH stat while cooling,α –stat while rewarming

• pH stat while rewarming,α –statwhile cooling

Cerebral autoregulation is maintained better in

• α –stat Management

• pH stat Management

Ideal CVP to be maintained during retrograde cerebral perfusion

• <5mmHg

• <25 mmHg

• <45mmHg

• >60mmHg

Ideal AMP maintained during Anterograde cerebral perfusion

• > 40mmHg

• > 60 mmHg

• > 80mmHg

• > 100mmHg
