Brief Summary
Increasing duration of local anesthetic action is desired for prolongation of postoperative patient comfort, as well as decreasing perioperative opioid consumption and subsequent side effects. Calcitonin, discovered in 1961, has been established, synthesized, and developed for use in treating disease. In 1983 it was demonstrated that calcitonin is an analgesic, which is also effective in the epidural and subarachnoid spaces.Tramadol abuse has dramatically increased in Egypt since 2008 and has led to many admissions to addiction treatment centers.It was shown that the duration of sensory block of spinal anesthesia with hyperbaric bupivacaine in chronic opium abusers undergoing lower extremity orthopedic surgery was much shorter in chronic opium abusers compared with non-abusers.
