Introduction:
Opioid-induced constipation (OIC) is a principal complication secondary to analgesic therapy for cancer pain patients who suffer moderate to severe pain. In this study, we observe the efficacy and safety of transcutaneous acupoint interferential current (IFC) stimulation in those patients with OIC.
Methods:
A total of 198 patients were randomly allocated to the IFC group and control group in a 1:1 ratio. Finally, 98 patients in the IFC group received 14 sessions administered over 2 weeks, whereas 100 patients in the control group took lactulose orally during the same period. Observation items were documented at management stage and at follow-up stage according to Cleveland Constipation Scales (CCS), pain Numeric Rating Scales (NRS) and Patient Assessment of Constipation Quality of Life (PAC-QoL).
Results:
The total curative effects of the IFC group and the control group were indistinguishable (76.5% vs 70.0%, P = .299). Regarding CCS and PAC-QoL scores, no significant difference was observed between the 2 groups during the management time and at the follow-up stage of week 3 ( P > .05, respectively), but groups were distinguished at the follow-up stage of week 4 ( P < .001 and P = .031, respectively). The pain NRS decreased significantly at management stage week 2 and follow-up stage week 3 and week 4 ( P = .013, P = .041, P = .011, respectively).
Conclusions:
Transcutaneous acupoint IFC therapy over acupoints of Tianshu (ST25) and Zhongwan (RN12) may improve constipation and quality of life in cancer patients receiving opiates; further studies are worthwhile.
