Labour Epidural Rates  The Rotunda Hospital 67%  USA 66%  Ireland 33%  Europe 25%

‘labour results in severe pain for many women. There is no other circumstance where it is considered acceptable for a person to experience untreated severe pain, amenable to safe intervention, while under a physician's care.’ American College of Obstetrics & Gynecology

Methods of Maintaining Epidural Analgesia Intermittent ‘Top-Ups’ Continuous infusions (8-12 mls/hr) Patient Controlled (PCEA) – ± Background infusion

Epidural Patient-Controlled Analgesia

PCEA use: ~40% USA Bucklin BA. Anesthesiology 2005;103:645-53

PCEA vs Continuous Epidural infusion van der Vyver. BJA Studies of 640 patients Continuous vs PCEA with no basal rate PCEA groups – Less local anaesthetic – Less leg weakness – Fewer anaesthetic interventions

Benefits of Minimising Local Anaesthetic Usage Patient Satisfaction Ability to Void increased Less Hypotension Obstetric Outcome improved Ambulation

“In the kingdom of the blind, the one-eyed man is King.” D. Erasmus “An idiot with an ultrasound probe is still an idiot.”

“ Evidence on Ultrasound-guided catheterisation of the epidural space is limited in amount, but suggests that it is safe and may be helpful in achieving correct placement.”
