[Case-control study on application of auricular acupuncture for the treatment of analgesia during perioperative period in total hip arthroplasty].
OBJECTIVE
To investigate clinical effects of auricular acupoint (AA) in the treatment of analgesia during perioperative period in total hip arthroplasty.


METHODS
From March 2008 to August 2010, 60 patients with late osteonecrosis of the femoral head were treated by total hip arthroplasty and randomly divided into auricular acupuncture (AA) group and control group, 30 patients in each group. There were 11 males and 19 females in the AA group,with an average age of (60.93 +/- 5.90) years; the patients were treated with auricular acupuncture on the point of Shenmen, Subcortex, Kidney and hip joint for four times a week. There were 12 males and 18 females in control group, with an average age of (59.87 +/- 6.21) years; while the patients without auricular acupuncture. VAS score was used to evaluat the degree of pain; Harris score was used to evaluat the function of hip joint. All patients received patient controlled analgesia pump (PCA) for 48 hours after surgery (400 ml liquids were in PCA pump, including 800 mg tramadol and 0.8 mg fentanyl). The dosage of liquids and adverse reaction of PCA pump in different time were recorded.


RESULTS
The VAS score on the 3rd, 4th, 5th and 7th day separately was (3.61 +/- 0.29), (3.59 +/- 0.30), (2.97 +/- 0.26), (2.29 +/- 0.45), and lower than control group, which separately was (4.19 +/- 0.28), (4.00 +/- 0.31), (3.15 +/- 0.29), (2.83 +/- 0.31). The dosage of PCA in AA group separately was (72.27 +/- 8.06), (60.40 +/- 8.16), (44.13 +/- 4.75), (40.40 +/- 3.69), and less than control group, which was (86.27 +/- 8.51), (73.87 +/- 8.32), (54.53 +/- 5.20), (44.67 +/- 6.31) on the time of 0-12, 12-24, 24-36 h and 36-48 h after surgery. During the using of PCA, nausea and vomiting occurred in 5 cases, less than control group (21 cases). Harris score in AA group (78.90 +/- 5.14) was higher than control group (73.37 +/- 5.99) 2 weeks after operation.


CONCLUSIONS
Auricular acupuncture can reduce postoperative pain, reduce the usage of analgesic and complications, such as nausea and vomiting, improve the function of hip joint after operation.
