Additional Topics: Pain Management
In this chapter several topics related to anesthesia for pain management are discussed. Subtopics include anesthetic management of patients with complex regional pain syndrome (CRPS) types 1 and 2, performing a stellate ganglion block, and prevention of local anesthetic toxicity. The chapter begins with a discussion of the mechanisms of pain onset. Next, evaluation and treatment of chronic pain are addressed. Trigger points in myofacial pain are outlined and the mechanism of transcutaneous electrical nerve stimulation (TENS) presented. A case involving a pregnant patient on chronic methadone therapy is presented. Management of cancer pain, post-amputation pain, and lower back pain and sciatica are also addressed. Each scenario is presented as a short, three- to four-question additional topic.
