Abstract

The tourniquet is usually applied for the orthopedic surgeries on the lower extemity to obtain the bloodless surgical field and to reduce blood loss.However, there are various complications such as nerve and tissue damage from compression, hemodynamic changes, and metabolic changes from ischemia after applieation of the tourniquet. Release of the tourniquet with reperfusion of the lower limb results in transient core body temperature change and other important hemodynamic, respiratory, and metabolic changes. I observed the mild core temperature drop following the release of the tourniquet at the surgical procedure of the lower extremity during inhalation anesthesia. The results were as follows ; The mean drop in temperature of 0.5 degree (about 11.9 min ; mean) was observed following the tourniquet release. Compared with the baseline value, the decreases in temperature at 8, 10 and 15 min, were statistically significant. There was significant correlation between the duration of tourniquet application and temperature drop (r= 0.293).
