Swelling/ Edema

This study is a multicenter, open-label, randomized controlled trial planned to enroll patients with ankle fractures who meet the inclusion and exclusion criteria and are scheduled to undergo internal fixation surgery from the emergency and inpatient wards of multiple hospitals. General and disease-related data will be collected. All eligible patients must voluntarily sign an informed consent form after understanding and accepting the study. Successfully recruited participants will undergo internal fixation surgery at a scheduled time and then be randomly assigned to either the Venostan (horse chestnut seed extract tablet) group or the conventional treatment group. They will receive the corresponding treatments according to the study protocol. Follow-up assessments will include changes in ankle circumference, ankle range of motion, scale evaluation results, laboratory test results, and adverse events. The study aims to evaluate the effects of Venostasin in patients with ankle fractures undergoing internal fixation surgery, exploring its potential to promote postoperative reduction of ankle swelling, enhance early joint function recovery, and investigate its safety in postoperative fracture management.

This clinical trial aims to investigate whether dexamethasone decreases edema and trismus in adults undergoing lower third molar surgical extraction. The main question it aims to answer is: Does dexamethasone submucosal injection have a positive impact on trismus and edema after third molar surgery compared to conventional postoperative prescription? Participants will: * Be administered with dexamethasone submucosal injection or a placebo after the surgery. * Visit the clinic three times the week after the extraction for follow-up.
