Randomized Controlled Trial Comparative Study
Postoperative pain significantly influences postoperative blood loss in patients undergoing total knee replacement.
Although hypertension has long been recognized as a factor that might increase intraoperative blood losses in major orthopedic surgery, the effects of postoperative pain-induced hypertension on blood losses have not so far been evaluated. The aim of this study was to evaluate the effect of pain on perioperative blood losses of patients undergoing primary total knee replacement (TKR). ⋯ In patients undergoing TKR, there is a significant correlation between measured blood loss and morphine consumption from 12 to 18 hours. It is concluded that postoperative pain significantly influences postoperative blood loss in patients undergoing TKR.

Functional restoration programs for chronic low back pain (CLBP) have been shown to be successful in improving function and, to a lesser extent, in reducing pain. The Munich Functional Restoration Program (MFRP) is a 4-week outpatient program designed to reduce pain and to improve health-related quality of life in patients with a long history of CLBP. ⋯ Compared with standard treatment, a functional restoration program for CLBP significantly improves some aspects of health-related quality of life. It results in a decrease of pain and pain-related disability even in patients with a long history of CLBP.
