Short-term CVCs are frequently encountered in the operating room and ICU. These catheters are placed at the bedside and can be useful in emergencies. They are noncuffed and single (cordis introducer) or multilumen (dual or triple lumen catheters). The large diameter of cordis introducers allows large volume resuscitation and passage of smaller Swan-Ganz catheters and trans-venous pacers. Multilumen CVCs are smaller in diameter and useful for multiple infusions and blood draws. Overall, short-term CVCs require constant vigilance and care to prevent infection and dislodgement.
