# Efficacy of Ropivacaine for Sub-Arachnoid Block in Patients with Recent History of Scorpion Sting: A case series

## TL;DR

This case series shows that ropivacaine works well for spinal anesthesia in patients recently stung by scorpions, where bupivacaine might fail.

## Contribution

The study introduces ropivacaine as a successful alternative to bupivacaine for spinal anesthesia in patients with recent scorpion stings.

## Key findings

- Ten patients with recent scorpion stings successfully received sub-arachnoid block using 0.75% hyperbaric ropivacaine.
- Ropivacaine prevented SAB failure and avoided the need for general anesthesia in these patients.

## Abstract

Failure of sub-arachnoid block (SAB), due to resistance to bupivacaine after a recent scorpion sting can lead to multiple block attempts and subsequent conversion to general anaesthesia. We report this case series of 10 patients with successful SAB with newly launched 0.75% hyperbaric ropivacaine, in patients with recent scorpion sting. Thus, intrathecal hyperbaric ropivacaine may be considered as the local anaesthetic agent of choice in patients with scorpion sting to prevent failure of SAB.
