Anesthetics May Cause Pain After Surgery
Anesthesia drugs used for cutting pain during surgery may increase pain and discomfort after the surgery.
The finding comes from a team of researchers from Georgetown University Medical Center and suggests the mechanism of how Anesthetics may cause pain after surgery.
Researchers suggest that 'noxious' anesthesia drugs - which are the basic and commonly used drugs in the market - sensitize certain neurons in central nervous system, and this results in pain later after surgery. However, another group of anesthesia drugs - sevoflurane - targeting brain and spinal cord, don't have the side effects, but they are not that effective.
