Resuscitation in prone
Neuromonitoring
Spinal cord blood flow
Anterior median spinal artery supply territory
Redicular arteries
Posterior spinal artery anatomy
Posterior spinal artery territory
Perimedullary vessels
Boarder with highest ischemic risk
4 segments of regional spinal circulation cord
Adamkiewics
Segment with high susceptibility to Ischaemia
T4-7
Lumbar artery syndrome
Principlea that regulate blood flow
Wakeup test
How to maximise perfusion
Limitations of wakeup test
Neumetric Monitoring : sensory evoked potential
Neumetric Monitoring : sensory evoked potential
Neumetric Monitoring : sensory evoked potential: danger signs
Amplitude reduction > 50%
Increased latency > 10%
Neumetric Monitoring : sensory evoked potential limitations
Only monitors the dorsal column
Provides no evidence of motor function loss or anterior spinal cord injury
Neumetric Monitoring : sensory evoked potential reliability
Neumetric Monitoring : sensory evoked potential effects of voletiles
Neumetric Monitoring : sensory evoked potential effects of iv agents
Neumetric Monitoring : sensory evoked potential effects of biological factors
Neumetric Monitoring : sensory evoked potential, ideal anaesthetic approach
Neumetric Monitoring : sensory evoked potential, how is it done
Prone baseline recording,
Maintain anaesthetic depth, CO2, temperature and BP
Intraoperative consideration for ssep
Criterion for decreased ssep
Amplitude reduction by 40%
Motor evoked potential
Transcranial
Spinal cord
Transcranial MEP vs Sseps
Lag 5min ssep
MEP false pos <10%
Anaesthetic agent effects on MEP
Ideal anaesthesia for mep
Causes of blood loss
Blood loss monitoring
Strategies to minimise blood loss
Induced hypotension
Change in surgical techniques
Antifibrinolytic
Decrease homologous blood transfusion
Preop autologous blood donation
Cell salvage
Normovolaemic hemodilution
Apheresis
Acute Normovolaemic hemodilution technique
Complications
Pulmonary edema
Anasarca
