The concept of PICC insertion in a patient who has assumed the sitting position is simple and feasible; it is unclear why the technique has not been previously reported. However, many clinicians may prefer to use centrally inserted central venous catheters, rather than PICC, in patients with acute heart failure. Recently, PICC has been used for venous access in critically ill patients. Clinicians must consider the risks of catheter-related complications, which comprise deep vein thrombosis and bloodstream infection, when selecting the type of catheter. No differences have been reported in rates of infectious complications between PICC and centrally inserted central venous catheter approaches in critically ill patients. However, there remains disagreement regarding rates of thrombotic complications between these approaches for critically ill patients.[4,5] Placement of a centrally inserted central venous catheter involves a risk of air embolism when patients are in sitting or upright positions.[6,7] Brederlau et al reported successful ultrasound-guided internal jugular vein catheterization with a patient position of 30° dorsal elevation under mechanical ventilation. In that case, positive end-expiratory pressure (at least 10cm H2O) may have been effective in prevention of air embolism.
