This Concept Map, created with IHMC CmapTools, has information related to: IVRA, Xylazine & Ketamine IM Why xylazine & ketamine? Ketamine is a commonly used injectable anaesthic which is used in conjunction with xylazine, Postoperative Outcome The distal part of the limb was desensitized, Intravenous Regional Anaesthesia (Bier Block) Complications Possibilities, Intravenous Regional Anaesthesia (Bier Block) Complications If the anaesthetic is injected slowly the cow can kick, Intravenous Regional Anaesthesia (Bier Block) Complications Formation of hematomas at the injection site., Intravenous Regional Anaesthesia (Bier Block) Complications Dorsal digital veins are hard to access, Intravenous Regional Anaesthesia (Bier Block) What is it? This method of anaesthesia is used when doing surgeries involving the distal aspect of the foot, The distal part of the limb was desensitized How does the area become desensitized? Lidocaine works by temporarily blocking the pain signals along the nerve., Intravenous Regional Anaesthesia (Bier Block) Complications IRVA does not always result in full analgesia of the interdigital space., Intravenous Regional Anaesthesia (Bier Block) How is it done? Procedure, Tourniquet was tied and the anaesthetic administered IV Why is a tourniquet used? The tourniquet must be tied tightly around the leg to prevent the flow of blood., Intravenous Regional Anaesthesia (Bier Block) Complications For IV administrations, drug preparations must not include adrenaline., Intravenous Regional Anaesthesia (Bier Block) Complications If the tourniquet is not placed properly, full analgesia will not be produced, Intraoperative Anaesthetic Tourniquet was tied and the anaesthetic administered IV, Preoperative Sedate & Restrain Xylazine & Ketamine IM
