The Influence of Timing of Botulinum Toxin Injection on Postoperative Pain Control Clinical Trial
Official title:
The Optimal Timing of Botulinum Toxin Injection for Pain Control in Patients Undergoing Hemorrhoidectomy-A Prospective, Randomized Study
This is a prospective, randomized study, which anticipatedly recruited 60 patients in the outpatient department who need hemorrhoidectomy from January 2019 to December 2019. After obtaining those patients' consent in the clinic, they were randomly assigned to two groups at a 1:1 ratio using a computer-generated list of random numbers (Microsoft Excel). One group received Botulinum toxin injection during the outpatient clinic one week before the operation(experimental group, EG), and the other group received injection during the operation(control group, CG). The two groups were compared for the influence of postoperative pain control and wound healing rate.
