Serving Chili Peppers (sort of) to Patients Undergoing Knee and Hip Replacement Surgery to Reduce Post-Surgical Pain
Researchers are "hot" on the trail to finding a new way to decrease post-surgical pain following painful operations such as knee and hip replacements. Surgeons are experimenting by dripping capsaicin - the ingredient that gives chili peppers their fire, directly into open wounds during knee replacement surgeries hoping that bathing surgically exposed nerves in a high enough dose will numb them for weeks. The theory takes root from the fact that when you bite into a hot pepper, after the initial burn your tongue goes numb. Research shows that capsaicin targets key pain-sensing cells in a way that blocks pain but does not impair other nerves responsible for functions such as movement. Its effects also last relatively long, thus reducing the need for morphine and other narcotics following surgery. In a pilot program of 50 knee replacements, the half treated with capsaicin used less morphine in the 48 hours after surgery and reported less pain for two weeks as compa
