| Purpose: |
|
The purpose of this study is to compare CVP measurements from CICCs and PICCs. The
investigators will also evaluate whether or not the duration of CICC placement affects the
differences in CVP measurements between the CICCs and PICCs. The investigators hypothesize
that the differences between the CVP measurements of the CICCs and PICCs will be clinically
insignificant.

| Study Summary: |
|
Centrally inserted central catheters (CICC) are commonly used in the intensive care unit
(ICU) for delivery of fluids, medications, and nutrition. They are also used to measure
central venous pressure (CVP) which provides critical information about blood volume status
and cardiac function of a patient. Currently, CICCs are the gold standard for measuring
CVP, but they have a number of associated risks including pneumothorax, major hemorrhage,
neck hematoma, and carotid puncture. An alternative to a CICC is a peripherally inserted
central catheter (PICC). A PICC can be placed with lower risks than a CICC, has a lower
rate of bloodstream infections, and provides longer-term IV access at a lower cost. PICCs
can be used to deliver fluids, medications, and nutrition. However, there is minimal
evidence that a PICC can measure CVP as effectively as a CICC. Therefore, a CICC is
preferred when a patient requires CVP monitoring in our ICU. Our aim is to compare CVP
measurements from CICCs and PICCs. We will also evaluate whether or not the duration of CICC
placement affects the differences in CVP measurements between the CICCs and PICCs. We
hypothesize that the differences between the CVP measurements of the CICCs and PICCs will be
clinically insignificant.
The goal of this study is to determine if the central venous pressure (CVP) measurements
obtained from a peripherally inserted central catheter (PICC) consistently correlate with
the CVP measurements obtained from a centrally inserted central catheter (CICC). If the
difference between the CVP measurements from the CICC and PICC are found to be clinically
insignificant, then it may be practical to place PICCs in favor of CICCs thereby avoiding
some of the potential complications associated with CICC placement. We also aim to evaluate
whether or not the duration of CICC placement affects the differences in CVP measurements
between the CICCs and PICCs. We hypothesize that the differences between the CVP
measurements of the CICCs and PICCs will be clinically insignificant.
