AbstractCentral venous catheters have had an increasingly important role in a variety of patient care situations, including long-term antibiotic therapy, chemotherapy, and nutritional support. The recent past has seen a gradual transition from placement of vascular access catheters by surgeons to placement by interventional radiologists. The interventional radiology service places a majority of the vascular access devices at our children's hospital, including peripherally inserted central catheters, tunneled central venous catheters, temporary and permanent hemodialysis catheters, and subcutaneous ports. Most procedures performed by our interventional radiology service in children can be successfully completed with use of intravenous (i.v.) sedation, and a few require general anesthesia (GA). Key advantages of GA over i.v. sedation include the ability to have positive pressure ventilation (PPV) or controlled apnea during the procedure. We report our experience of venous air embolism in three small children during placement of tunneled central venous catheters when GA was not used.
