Which anaesthetic modality is to be avoided in sickle cell disease?
General Anaesthesia
Brachial Plexus Block
Intravenous Regional Anaesthesia
Spinal Anaesthesia
IV regional anaesthesia is useful for rapid anesthetization of an extremity (upper or lower). A rubber bandage is used to force the blood out of the limb and a tourniquet is applied to prevent the re-entry of blood.This causes risk of massive hemolysis due to low oxygen tension or hemolytic crisis due to low blood flow.All the other given methods above don&;t carry that risk.
