Cohort Study of Auricular Acupressure for Postoperative Pain After Hemorrhoidectiomy
Cohort Study of Auricular Acupressure for Postoperative Pain After Hemorrhoidectiomy
Auricular pressure is effective for postoperative analgesia after hemorrhoidectomy, but the
 evidence is not sufficient.
This is a cohort 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 3 hours after the operation of the patients. By doctors' recommend interventions
 and the patients' preference, eligible subjects were naturally divided into the following
 queues: intravenous patient-controlled analgesia(IV-PCA),intravenous
 dezocine(IV-dezocine),intravenous patient-controlled analgesia+auricular
 acupressure(IV-PCA+AA),intravenous dezocine+auricular acupressure(IV-dezocine+AA). 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 3 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 main indicators will be analyzed by VAS score and generalized linear model, with VAS
 results as the dependent variable, grouping as the random factor, surgical method, mixed
 hemorrhoid classification as fixed effects factor, and age, course of disease, baseline VAS
 scores and VAS follow-up time point as the covariables to analysis VAS score improved
 relations between various factors. Analgesic usage, ease pain evaluation method and using the
 same scale and HAD GLM model analysis.The secondary indicator analgesic usage rate will be
 analyzed using logistic regression analysis. fixed effects and covariate factors set with the
 GLM model.

 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.
