Effect of Conicity Index and Body Mass Index on the Level of Spinal Anaesthesia

Abstract

Spinal anaesthesia is a popular form of regional anaesthesia for surgeries below the umbilicus. It involves injecting a small amount of drug into the subarachnoid space to achieve adequate anaesthesia. Recent studies suggest that obesity may lead to greater spread of spinal anaesthesia due to reduced CSF volume. Obesity also affects the level of anaesthesia achieved and is associated with increased cephalic extension levels. This study aims to investigate the effects of Conicity Index (CI) and Body Mass Index (BMI) on the level of spinal anaesthesia.
