We reviewed 100 cases to study the effect of use of physiological saline with epinephrine for the control of bleeding during total knee arthroplasty. We compared two groups, one which used epinephrine, and the other which did not and was the control group. The amount of total blood loss was an average 422.7 ml in the epinephrine group compared with 523 ml in the control group (p <0.005) . The patients in the two groups were similar as to sex, age, knee disease, and surgical technique, with the exception of the use of epinephrine. The technique to use epinephine is simple: Mix 1μl epinephrine with 200 ml physiological saline. Gauze soaked in 150 ml of the physiological saline with epinephrine is used to cover the operative field as a hemostasis perioperatively. After the incision is sutured, the joint cavity is filled with the remaining 50 ml of physiological saline with epinephrine through a drainage tube and drainage clamp. The closed suction drainage is opened one hour after operation. This new technique using physiological saline with epinephrine is simple, inexpensive and effective.
