This case-based procedural review presents the placement of a pentalumen central venous catheter in the left internal jugular vein in an intensive care setting. The lesson focuses on procedural reasoning and technique, including antisepsis with chlorhexidine and alcohol-based solution, wide sterile field preparation, ultrasound probe protection, local anesthesia, ultrasound identification of vascular structures, needle entry, guidewire passage, skin nick creation, dilation, catheter advancement, lumen testing, fixation, and final dressing.

The case highlights practical considerations relevant to critically ill patients, including limited neck access, the need for multiple infusion routes, and the importance of maintaining sterility throughout the procedure. The content is intended for educational review and should be interpreted in the context of local protocols, institutional standards, supervision requirements, and current clinical guidelines.
