Postoperative Pain After Hemorrhoidectomy Clinical Trial
Official title:
Cohort Study of Auricular Pressure Therapy for Intervention of Postoperative Pain of 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.
