[Analgesic Effect of Induced by Needling at Sanyinjiao (SP 6) Acupoint on Primary Dysmenorrheal Patients with Cold Damp Stagnation Syndrome].

OBJECTIVE

To observe the analgesic effect of induced by needling at Sanyinjiao (SP 6) on primary dysmenorrheal (PD) patients with cold damp stagnation syndrome (CDSS).

METHODS

A total of 64 PD patients with CDSS experiencing abdominal pain (≥40 mm in visual analogue scale ，VAS) were randomly assigned into -expectation(DE) group(＝15) and no--expectation(NDE) group(＝49). On the first day of abdominal pain attack, bilateral SP 6 were punctured respectively with thicker needles with deeper insertion for -expectation patients and thin filiform needles with shallow insertion for no--expectation patients. The needles were removed after 30 minutes, a scale was used to evaluate the condition. According to the results, patients in the DE group were further divided into DE group and no- DE group, patients in the NDE group were also divided into NDE group and no- NDE group. The VAS was used to evaluate the patients' abdominal pain severity before treatment and 0, 10, 20, 30 min after acupuncture needle withdrawal.

RESULTS

The rate of in the DE group was higher than that in the NDE group(<0.05). The VAS scores of abdominal pain in the four groups were decreased at all time-points after needle withdrawal compared with those before treatment (<0.01), while the VAS score in the DE group were lower than in the no- NDE group 30 min after needle withdrawal (<0.05).

CONCLUSION

The intervention method of thick needle, deep insertion and some manipulation is easier in inducing than that of thin needle, shallow insertion and no manipulation. The analgesic effect of is better than that of no- for PD patients with CDSS.
