  • Image not available. In addition to potent analgesia, regional anesthesia may lead to reductions in the stress response, systemic analgesic requirements, opioid-related side effects, general anesthesia requirements, and possibly the incidence of chronic pain.
  • Image not available. Regional anesthetics should be administered in an area where standard hemodynamic monitors, supplemental oxygen, and resuscitative medications and equipment are readily available.
  • Image not available. Local anesthetic may be deposited at any point along the brachial plexus, depending on the desired block effects: interscalene for shoulder and proximal humerus surgical procedures; and supraclavicular, infraclavicular, and axillary for surgeries distal to the mid-humerus.
  • Image not available. A properly performed interscalene block invariably blocks the ipsilateral phrenic nerve, so careful consideration should be given to patients with severe pulmonary disease or preexisting contralateral phrenic nerve palsy.
  • Image not available. Brachial plexus block at the level of the cords provides excellent anesthesia for procedures at or distal to the elbow. The upper arm and shoulder are not anesthetized with this approach. As with other brachial plexus blocks, the intercostobrachial nerve (T2 dermatome) is spared.
  • Image not available. The axillary, musculocutaneous, and medial brachial cutaneous nerves branch from the brachial plexus proximal to the location in which local anesthetic is deposited during an axillary nerve block, and thus are usually spared.
  • Image not available. Often it is necessary to anesthetize a single terminal nerve, either for minor surgical procedures with a limited field or as a supplement to an incomplete brachial plexus block. Terminal nerves may be anesthetized anywhere along their course, but the elbow and the wrist are the two most favored sites.
  • Image not available. Intravenous regional anesthesia, also called a Bier block, can provide intense surgical anesthesia for short surgical procedures (45-60 min) on an extremity.
  • Image not available. A femoral nerve block alone will seldom provide surgical anesthesia, but it is often used to provide postoperative analgesia for hip, thigh, knee, and ankle procedures.
  • Image not available. Posterior lumbar plexus blocks are useful for surgical procedures involving areas innervated by the femoral, lateral femoral cutaneous, and obturator nerves. Complete anesthesia of the knee can be attained with a proximal sciatic nerve block.
  • Image not available. Blockade of the sciatic nerve may occur anywhere along its course and is indicated for surgical procedures involving the hip, thigh, knee, lower leg, and foot.
  • Image not available. Popliteal nerve blocks provide excellent coverage for foot and ankle surgery, while sparing much of the hamstring muscles, allowing lifting of the foot with knee flexion, thus easing ambulation. All sciatic nerve blocks fail to provide complete anesthesia for the cutaneous medial leg and ankle joint capsule, but when a saphenous (or femoral) block is added, complete anesthesia below the knee is provided.
  • Image not available. A complete ankle block requires a series of five nerve blocks, but the process may be streamlined to minimize needle insertions. All five injections are required to anesthetize the entire foot; however, many surgical procedures involve only a few terminal nerves, and only affected nerves should be blocked.
  • Image not available. Intercostal blocks result in the highest blood levels of local anesthetic per volume injected of any block in the body, and care must be taken to avoid toxic levels of local ...
