These guidelines, made by BARA, are, like the "Safety First Guidelines" of the SARB, clinical recomendations for a good and safe practice when performing peripheral nerve blocks (PNB). These recommendations were made according to the most recent literature and experts opinion and are therefore prone to changes due to evolution of literature. The guidelines deal with "Informed Consent", preoperative visit, monitoring, equipment and the PNB procedure itself regardless of using ultrasound or neurostimultion or both. Advise is given when combining a PNB with general anesthesia and when a catheter technique is used.
