Which patient would most likely need a peripherally inserted central catheter (PICC)?

The choice of a peripherally inserted central catheter (PICC) is primarily influenced by the patient's need for long-term intravenous therapy or frequent blood draws, as well as their vascular access requirements. In this case, a neonate requiring blood therapy is typically a patient with delicate vascular needs.

Neonates often have small veins that may not be suitable for standard peripheral IV access, and they may require access for an extended period due to their medical conditions. Blood therapy for neonates can involve repeated transfusions or medication administration that may necessitate a more stable and reliable access point, which a PICC can provide.

The specialized nature of a PICC allows for infusion of larger volumes and administration of irritant medications or solutions, which is especially necessary when treating neonates who may be severely compromised and could require multiple therapies simultaneously without risking damage to the veins. Thus, the need for a central access point makes the selection of a PICC the most appropriate for a neonate requiring blood therapy.
