Femoral Arterial Cannulation Performed by Anesthesia Residents: A Comparison Between Ultrasound-Guided Modified Dynamic Needle Tip Positioning, Short-Axis, Out-Of-Plane and Conventional Short-Axis, Out-Of-Plane Methods

What this Trial Is About

Researchers are evaluating the ultrasound-guided "Modified Dynamic Needle Tip Positioning, Short-Axis, Out-Of-Plane" (MDNTP-SAOP) technique compared to the "Conventional, Short-Axis, Out-Of-Plane" (C-SAOP) technique for femoral arterial cannulation performed by anesthesia residents in infants and children undergoing cardiac surgery. The study aims to find out which method requires less time for successful cannulation at the first puncture site and to assess safety and efficacy in this pediatric population. Participants under 12 years old will be randomly assigned to receive femoral arterial cannulation using either the MDNTP-SAOP method or the C-SAOP method. Both groups will undergo the procedure during surgery, and the study is double-blinded, meaning patients and research staff will not know which technique is used. The procedures will be performed by anesthesia residents, and data on time taken for cannulation, number of attempts, success rates, and number of cannulae used will be collected. Throughout the study, researchers will monitor participants for adverse events such as thrombosis, hematoma, infection, or limb ischemia at the insertion site on the first and third days after surgery. The main measure is the time from skin penetration to proper catheter placement during the operation. The study will also record the number of attempts and success rates during the procedure. The trial will continue until January 2027 with careful safety and outcome monitoring.
