A Case of Success of Subarachnoid Block Using 0.75% Hyperbaric Ropivacaine in Previous Multiple Failed Attempts at Spinal Anaesthesia

Dr. Shourya Bhosale, Dr. Yogita Agrawal, Dr. Saloni Shah

Abstract: This report explores the impact of scorpion bites on the effectiveness of Sub-Arachnoid blocks (SAB) in surgical patients, primarily in the rural Indian subcontinent. It is observed that the scorpion venom interferes with the action of local anaesthetics by affecting voltage gated sodium channels, resulting in a resistance to these drugs. A case report of a 45-year-old woman who underwent fistulectomy in a Mumbai based hospital is presented. Despite her history of scorpion bites and previously failed subarachnoid blocks, she successfully received SAB with 0.75% hyperbaric Ropivacaine, achieving sensory and motor blockade for up to three hours. This case suggests the potential of newer anaesthetic molecules to overcome resistance caused by scorpion venom, though further research is required for definitive conclusions.
