Peripheral nerve blocks are an extension of regional anesthesia practiced by many anesthesiologists. Operations including C-section, total joint replacement and even bowel resection can all be performed with regional anesthesia.
In pain management setting, procedures such as occipital, ilioinginal and genitofemoral nerve blocks are all examples of how peripheral nerve blocks can be used to treat various painful conditions.
In general, a combination of cortisone and long-acting local anesthetic is injected in order to provide pain relief and reduce nerve irritation. These procedures are usually done at bedside but ultrasound guidance is increasingly being evaluated for improving treatment accuracy.
