Cruative Effect Of Huoxuezhentong Tang Treeting Exercise-induced Pain After Operation Of Fractures Around The Knee Joint

Object:To find a pain relief method and promote early functional rehabilitation of patients, we did this randomized controlled study, making objective observation of Huoxuezhentong Tang’s effect on exercise-induced pain release after operation of bone fractures around the knee joint.Methods:We randomly divided 90 patients who received treatment in our hospital during Jul. 1,2014 to Jan.31,2016 and met the inclusion criteria (50 patellar fractures and 40 tibial plateau fractures) into two groups, the experimental group and the control group. The control group were treated according to common practice, and the experimental group were treated with common practice and modified Huoxuezhentong Tang together. The visual analogue pain scale and the frequency of using analgesics were observed on the first, third, fifth and seventh day after operation, at the same time, patients’ satisfaction toward pain management and range of motion were recorded within 7 days after operation.Results:There were 84 cases (47 patellar fractures and 37 tibial plateau fractures) involved in the result analysis.43 patients (24 patellar fractures and 19 tibial plateau fractures)were from the experimental group and 41 patients (23 patellar fractures and 18 tibial plateau fractures)were from the control group.The comparison on exercise-induced pain after operation:the difference of the two groups on the first day was not statistically significant (P>0.05); on the third, fifth and seventh day, the experimental group felt less pain than the control group, and there was a statistically significant difference between the two groups (P<0.05); in each group, the pain scale decreased progressively from the third day to the fifth day and to the seventh day, and both the grade of decreasing was statistically significant (P<0.05).The difference of the two groups in terms of frequency of using analgesics was statistically significant (P<0.05),the control group used analgesics more frequently.The difference of the two groups in terms of patients satisfaction toward pain management was not statistically significant (P>0.05).74.4% of the patients were very satisfied with the effect, 18.6% satisfied with the effect and 7% basically satisfied with the effect in the experimental group; and 51.2% of the patients were very satisfied with the effect,41.5% satisfied with the effect and 7.3% basically satisfied with the effect in the control group. None of the patients in both groups were unsatisfied with the effect of pain release.The difference of the two groups in terms of range of motion was not statistically significant (P>0.05) on the first day; while on the third, fifth and seventh day, there was a statistically significant difference between the two groups(P<0.05)-the range of motion in the experimental group was larger than that in the control group. In each group, the range of motion increased progressively from the first day to third day, to the fifth day and to the seventh day; both of the differences were statistically significant(P<0.05).The comparison on the relation between the range of motion and exercise-induced pain:the range of motion was negatively related to exercise-induced pain from the first day to the seventh day (P<0.05).Conclusion:Huoxuezhentong Tang played a positive role in the exercise-induced pain release after operation of bone fractures around the knee joint. It was beneficial to patients’.postoperative recovery, at the same time, it could reduce the use and the side effects of western analgestic drugs.
