The recovery from surgery may be less of a trial if the nerves are numb right of patients prior to surgery. A clinical study reported in tomorrow's issue of Journal of the American Medical Association shows that blocking the potential pain impulses to the spinal cord before making a surgical incision instead of waiting for the results up that the procedure is completed in less pain and a faster recovery.
most physicians now provide pain relief to patients after surgery, by numbing the nerve receptors. However, research on laboratory animals have shown that traumatic experiences can rewire the nervous system to provide a persistent painful feeling long after the stimulus is removed. If the nerves do not feel the stimulus first, the pain response will not wired - and new pain signals can be blocked
To see if it works in people also directed team by Allan Gottschalk. and David Smith from the University of Pennsylvania Medical Center in Philadelphia followed 100 patients whose prostate glands were removed. They injected 66 subjects prior to surgery or with a narcotic anesthetic which prevents signals from reaching the spinal cord. During the hospital stay, the patients reported feeling pain which was 33% less intense than those who had not received treatment. In addition, 87% of these patients reported feeling any pain during the investigation 9.5 weeks after surgery, compared to only 47% of those treated conventionally.
The procedure can not become common in the operating room unless the benefits listed to outweigh the complications observed in the study, such as fluctuating blood pressure during surgery, says Smith . However, the implications of the study are much broader than the prevention of post-surgical pain, notes Daniel Carr, pain management professor at the New England Medical Center in Boston. For example, giving a child a local anesthetic before the blood sample could not only numb the needleprick, but also can reduce the emotional or physical sensitivity to long-term needleprick.
