This video demonstrates a practical technique for infraclavicular subclavian vein cannulation without ultrasound guidance, particularly valuable in resource-limited settings. The method is applied in a pediatric surgical case involving long-gap esophageal atresia requiring colon interposition. Emphasis is placed on anatomical landmarks, catheter insertion steps, sterile precautions, and continuous cardiac monitoring. The video serves as a training tool for healthcare professionals, illustrating efficient and deliberate movements that enable effective central venous access in environments where advanced imaging is unavailable.
