Brief summary

Ultrasound assessment of the lumbar region prior to neuraxial blockade is becoming more popular. Trials have demonstrated a smalll benefit in thin patients. It is hypothesised that a bigger benefit will be found in obese patients in whom it is difficult to determine lumbar anatomy by traditional palpatio techniques.

Interventions

Immediately prior to the insertion of the epidural, three ultrasound views of the lumbar bony anatomy will be performed. 1) Finding the superior aspect of the iliac crests, 2) Finding the midline of the lumbar spine 3) Finding the level of an appropriate ligamentum flavum to target for the insertion of the epidural. This information is combined to give both the site for the needle insertion and the direction to advance the needle. The study is planned to be completed in less than 12 months.
