Regional and Parenteral Analgesia in Labour

Labour pain is a complex phenomenon involving subjective psychological factors and physiological neurohormonal factors. Many different factors contribute to the perception of pain: cultural factors, bond, and trust in the delivery team, being able to take their own decisions, relaxation ability, previous labour, anatomical and fetalrelated factors. Pain relief is one of the elements involved in overall satisfaction but it is not the only one and is important to remember that pharmacological intervention is only a part of it.
