简要总结
Neuraxial anaesthesia is one of the most commonly used modes of regional anaesthesia. However,
anatomical landmarks based physical assessment has been misleading in 30% of the cases resulting in a
failure rate of around 2-20%. Bony structure, spinal anatomy, unidentified anatomical landmarks, excess
BMI, inappropriate patient positioning, intervention method, experience of anesthetist, and equipment
are considered as reasons of failure.
The most important factor affecting success during spinal and epidural interventions is the patient’s
positioning. A prosperous positioning of the patient widens the interspinous distance and ensures an
increased chance of successful needle placement. Optimally flexed position that reduces lumbar lordosis
and opens the intervertebral space may help in reducing the failure rate. A meta-analysis has proven the
increased intervention success of neuraxial anaesthesia performed using ultrasonography. This study
aims to identify which position, has the maximum interspinous distance and patient comfort; using
ultrasonography.
