Recomendations for standard monitoring during general anaesthesia and recovery has been published and well established by various anaesthesia societies including AAGBI (Association of Anaesthetists of Great Britain and Ireland), RCA (Royal College of Anaesthetists) , ESA (European Society of Anesthesiologists) , just too only mention a few. The same monitoring principle apply to any interventions under regional anesthesia, both neuraxial and peripheral plexus anaesthesia. How to monitor needle trajectory and final tip position has not been clearly defined. Anatomical landmarks and paresthesia were widely accepted end points until mid seventies when nerve stimulator was introduced into contemporary regional anaesthesia practice . Nerve stimulator introduction came not without criticism – and famous become quote “ no paresthesia no analgesia”.
