The Study Of Huoxue Tongluo On Preemptive Analgesia During Perioperative Period Of Total Knee Arthroplasty

ObjectiveTo study promoting blood circulation to remove meridian obstruction on preemptive analgesia during perioperative period of Total Knee ArthroplastyMethodsThis was a prospective, randomized, patient and observer blind control study. Eighty-six patients underwent TKA were randomized into the study group, control group and the blank group. The study group received Huoxue Tongluo of Chinese medicine before and after operation, along with femoral nerve block for postoperative pain management.The control group received Huoxue Tongluo of Chinese medicine only after operation, along with with femoral nerve block for postoperative pain management. The blank group received only femoral nerve block for postoperative pain management. Pain was assessed at rest and during movement using a visual analog scale(VAS). Joint function was also assessed using the hospital for special surgery (HSS). The consumption of analgesic in 7d after surgery was recorded. Body temperature, hemoglobin were monitored.ResultsVAS at rest was improved Pnificantly in study groups. Compared with the control group (P<0.0167). Compared with the blank group (P<0.0167). The recorded of body temperature was reduced Pnif icantly in study groups. Compared with the control group (P<0.0167). Compared with the blank group (P<0.0167). The recorded of hemoglobin was increased Pnif icantly in study groups. Compared with the blank group(P<0.0167).ConclusionThe promoting blood circulation to remove meridian obstruction preemptive analgesia combining femoral nerve block Pnificantly improved postoperative VAS at rest,reduced body temperature and the consumption of analgesic, increased hemoglobin after TKA.
