Clinical Trial Summary

Auricular pressure is effective for postoperative analgesia after hemorrhoidectomy, but the evidence is not sufficient.

Description:

This is a randomized, double-blind study to study the analgesic effect of auricular pressure pill on persistent pain after hemorrhoidectiomy. Baseline pain intensity scores (VAS>3) of the subjects will be collected 24 hours after the operation of the patients. Eligible subjects will be randomly assigned to receive auricular pressure pills or sham-auricular pressure pills. The treatment will last 5-7 days. Participants will receive auricular pressure once two days, and receive VAS, concomitant medication, PONV intensity scale and peripheral edema were recorded daily, and after the operation 24 hours, 3 days and 7 days the patients will receive anxiety and depression scale(HAD) , and VAS data will be collected by telephone at 3 and 6 months after the operation.

The statistical analysis results will be subject to the full analysis set (FAS) results, and a sensitivity analysis will be performed comparing the per-protocol (PP). The main indicators will be analyzed by covariance analysis, with VAS results as the dependent variable, grouping as the random factor, and age, course of disease, surgical method and baseline as the covariables to correct the P value. The secondary indicator analgesic usage rate will be analyzed using logistic regression analysis. Whether analgesic will be used as a dependent variable, grouping as a random factor, and age, course of disease, surgical method and evaluation time point will be analyzed as covariables. Other outcome indicators will be analyzed by covariance analysis, and the model will be the same as that of the main indicators. P<0.05 considered as significant difference, and SPSS20.0 used for analysis.

The purpose of this study was to seek high quality evidence-based medical evidence for intervention of auricular pressure pills on postoperative pain of hemorrhoidectomy.

Intervention

Other:
• Auricular pressure
Select related auricular points: Shenmen(TF4), sympathetic(AH6a), rectum(HX2), anus(HX5), stomach(CO4), subcortical(AT4). The auricle skin of the patient was disinfected 24 hours after the operation, and wanghuoxing seed will be used for stimulation. Ask patients press every two hours for one minute at each point. When the pain is severe, do pressure compressions at each point for 2 minutes once hour.
• Shame auricular pressure
Select unrelated auricular points: eye(LO5), occipital(AT3), tonsil(LO7,8,9), lower auricular root(R3), dorsum auricular kidney(P5) and dorsum auricular lung(P2). The auricle skin of the patient was disinfected 24 hours after the operation, and wanghuoxing seed will be used for stimulation. Ask patients press every two hours for one minute at each point. When the pain is severe, do pressure compressions at each point for 2 minutes once hour.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Tissue edema	The degree of tissue edema was observed and recorded truthfully.	Day 3, day4, day5, day6 and day7 after randomization.
Primary	Visual Analogue Scale(VAS)	It is a unidimensional measure providing a simple solution for measuring subjective experience. The VAS scale is a 10-cm line with 0 cm indicating no symptoms and 10 cm indicates the greatest extent of symptoms. Twenty-four hours after the operation, VAS>3 in the case of an analgesic pump can be included in the randomized control group.	Day 1 after randomization.
Secondary	Hospital Anxiety and Depression scale(HAD)	The HAD scale included measures of anxiety and depression, with scores ranging from 0 to 21. 0-7 points means asymptomatic;A score of 8-10 means suspicious;A score of 11 to 21 means definitely symptomatic( anxiety or depression).	Twenty-four hours, three days, and seven days after surgery
Secondary	The utilization rate of analgesic drugs(Diclofenac Sodium Dual Release Enteric-coated Capsules)	The ratio of patients using analgesic drugs in each group was calculated (Patients who take bisphenolics once are considered users), and the utilization rate = number of users/total number of users ×100%.	Day 7 after randomization.
Secondary	Amount of analgesic drugs (Diclofenac Sodium Dual Release Enteric-coated Capsules)	The total analgesic drugs dose of each group was was considered as the amount of analgesics in the group.	Day 7 after randomization.
