Relieving pain with nerve blocks.
Pain syndromes in elderly patients are seldom psychogenic or due merely to "old age." Careful differential diagnosis is important, as judicious use of nerve blocks as adjunctive therapy often can relieve pain and restore activity. In the acute phase of shoulder pain, intrabursal injection of local anesthetic and steroid inhibits the inflammatory process. In the later stages, suprascapular nerve block relieves pain and interrupts afferent pain pathways. The occipital pain and headache of cervical arthritis also often respond to injection of 2 to 3 ml of long-acting anesthetic into the greater and lesser occipital nerves at the sites where they pierce the trapezius. Minor causalgia, shoulder-arm syndrome, or chronic traumatic edema may follow either forearm fracture or inflammation around the shoulder joint. Five stellate ganglion blocks with 1% lidocaine on alternate days, followed by 3 to 4 months of active and passive exercise, is the most effective treatment. This regimen usually produces a fully functional extremity. In degenerative disk disease, osteoarthritis, and metastatic disease, the cause of back pain is essentially the same--edema and inflammation of nerve roots at the intervertebral foramina. Injection of local anesthetic and steroid into the epidural space usually reduces swelling and inflammation. Patients are evaluated in 2 weeks and reblocked if improvement has plateaued. Pain relief most often is prompt and persists for an indefinite period.
