The Clinical Study Of Transcutaneous Electrical Acupoint Stimulation For Adjuvant Analgesia After Total Hip Replacement

Objective: Through observing the clinical effect of transcutaneous electrical acupoint stimulation for adjuvant analgesia after total hip arthroplasty,to explore its ability to reduce the use of painkillers.Methods: From December 2016 to December 2017,60 patients with unilateral femoral neck fracture underwent total hip replacement in the Second Department of Bone of Fuzhou General Hospital were randomly divide into routine analgesia group(control group)of 30 cases and using transcutaneous electrical acupoint stimulation based on routine analgesia group(treatment group)of 30 cases.All patients underwent the total hip arthroplasty by the same doctors with the same type of anesthesia.And the two groups had the same treatment regimen of anti-osteoporosis,anti-coagulation and related original diseases after operation.The control group was treated without transcutaneous electrical acupoint stimulation after 6 hours of the operation,while the treatment group was treated with transcutaneous electrical acupoint stimulation after 6 hours of the operation.The VAS scores at the resting state before and after the surgery were recorded.And we recorded the VAS scores which was used by the patients of two groups at 6,12,24,36,48,and 72 hours after the operation,the first time of the PCA,the times that was used of PCA within 2 days after the operation,the dosages of oral NSAIDs drugs(Celecoxib Capsules),the dosages of intravenous infusion NSAIDs drugs(Flurbiprofen Axetil Injection),the dosages of intramuscular opioids(Pethidine Pydrochloride Injection)except the type of routine analgesia within 3 days after the surgery,occurrence of postoperative common complications,and Harris score 3 months after surgery.Results: There was no statistically significant difference in the VAS scores between preoperative and 6 hours after operation between the two groups(P>0.05).There was statistically significant difference in the VAS scores which were recorded at 12,24,36,48,72 hours after the operation(P<0.05),and the scores of treatment group was lower than that of control group.There was no significant difference in the dosage of oral NSAIDs drugs(Celecoxib Capsules),intravenous infusion NSAIDs drugs(Flurbiprofen Axetil Injection),intramuscular opioids(Pethidine Pydrochloride Injection)between the two groups(P>0.05).On the 2nd day after operation,the times that were be used of PCA in the treatment group was lower than that in the control group.The dosages of oral NSAIDs drugs(Celecoxib Capsules),intravenous infusion NSAIDs drugs(Flurbiprofen Axetil Injection)were lower in the treatment group on the 2nd and 3rd days after the operation than in the control group(P <0.05).There was no statistically significant difference in postoperative complications between the two groups(P>0.05).There was no statistically significant difference of the Harris score at 3 months after operation between the two groups(P>0.05).Conclusion: Transcutaneous electrical acupoint stimulation for patients after total hip replacement has a certain degree of analgesic effect,can reduce the use of painkillers.
