For PICC line insertion, what precautions are necessary?

• A. A tourniquet placed around his upper arm
• B. Sterile conditions
• C. Intravenous infusion of midazolam (Versed) for light anaesthesia
• D. Mr. Ford positioned with his head to the side to facilitate subclavian access

Answer: (B)

Maintaining sterile technique during PICC insertion is essential to prevent catheter-related bloodstream infection. Because the catheter travels from the arm into central circulation, any contamination can seed bacteria into the bloodstream, leading to serious infection. The key precaution is using a sterile field and aseptic practices: thorough hand hygiene, sterile gloves and gown, sterile drapes, and skin antisepsis with an appropriate agent (such as chlorhexidine in alcohol) before insertion, with the field kept sterile throughout and a clean, dressed site afterward. Other options may be used in some scenarios to aid access (like temporarily constricting a vein to dilate it) or relate to different routes or levels of sedation, but they are not universal infection-control precautions for PICC insertion. Sedation is not a routine requirement for this procedure, and head positioning to facilitate subclavian access pertains to a different vein entry approach.
