ClinConnect Summary

This clinical trial is comparing two methods for placing a special type of anesthesia called a combined spinal epidural (CSEA) in obese patients who need orthopedic surgery on their legs. The goal is to find out which method is more effective: using a technique based on anatomical landmarks (the visible parts of the body) or using ultrasound (a special imaging technique) to guide the placement of the anesthesia catheter. The study will include 60 patients aged 40 to 80 who have a Body Mass Index (BMI) over 30 and are scheduled for elective surgery.

To participate in this trial, patients must be in good health (ASA II-III) and have a BMI greater than 30. Those who have certain medical conditions, such as severe scoliosis or who do not agree to join the study, will not be eligible. Participants can expect to be assigned to one of two groups: one will have the catheter placement guided by ultrasound, while the other will have it done by feeling the body’s landmarks. The researchers will compare how successful each method is in placing the catheter on the first try, how many attempts are needed, and if there are any complications. This study aims to improve the anesthesia experience for obese patients undergoing surgery.
