Study of Pain and Related Factors During Microwave Ablation Treatment for Great Saphenous Vein Varicose Veins in Adults Aged 18 to 90

What this Trial Is About

Researchers are studying pain experienced during microwave ablation treatment for great saphenous vein varicosities, a type of varicose vein in the lower limbs. This observational study aims to analyze pain scores at various points during surgery and explore factors such as age, gender, body mass index, and the amount of swelling fluid used. The goal is to better understand and improve surgical techniques to reduce pain and enhance patient experience. The study involves measuring the great saphenous vein diameter before surgery using ultrasound and CEAP classification. Patients undergo endovenous microwave ablation combined with foam sclerotherapy and point stripping treatment. During surgery, researchers record pain scores at puncture and catheter insertion, swelling fluid injection, microwave generator operation, and surgery end. They also document factors like operating room temperature and tumescent fluid volume. The relationship between these factors and pain levels is analyzed to identify ways to manage pain better. Participants will have their pain assessed using the Visual Analogue Scale during surgery. Data related to surgery, including procedural details and pain scores, are collected throughout the operation. This study focuses on intraoperative pain and its correlation with treatment variables. The involvement includes preoperative examinations, intraoperative monitoring, and pain scoring. The study is expected to help improve anesthesia techniques and patient comfort during varicose vein treatments.
