Single-lumen 5Fr and Triple-lumen 6Fr PICCs Are Accurate for Hemodynamic Measurement by Transpulmonary Thermodilution.

Single-lumen 5Fr and Triple-lumen 6Fr PICCs Are Accurate for Hemodynamic

Peripherally inserted central catheters (PICCs) are increasingly used in intensive care unit (ICU) as an alternative to centrally inserted central catheters (CICCs) for intravenous infusion. In the present study the investigators try to assess their reliability for measuring cardiac index (CI) with trans-pulmonary thermodilution (TPTD) technique.

Inclusion Criteria:

• adult patients (≥18 years) admitted to the ICU
• Patients requiring hemodynamic monitoring using EV1000TM
• Patients having both PICC and CICC in place (these patients had their PICC replaced with a CICC, usually at the time of ICU admission, or vice versa, usually at the end of their ICU stay, and were enrolled immediately after the placement of the new device before the previous one was removed)

Exclusion Criteria:

• body weight <40 kg
• severe aortic regurgitation or intra-cardiac shunt
• treatment with an intra-aortic balloon pump
• contraindication for placement of PICC, CICC or a femoral arterial catheter
• abdominal aneurism
• extracorporeal circulation
• pregnancy
• lack of informed consent
