About

The study team will be performing a study comparing the use of Heparin Flushes vs. Normal Saline Flushes in making sure central lines stay open. The participants will be placed in a group to receive the University of Texas Southwestern Medical Center (UTSW) Standard of Care (control group) for maintaining central lines, or a group to receive Normal Saline Flushes only (experimental group) to keep their central line open. The participants electronic medical record will be reviewed by study team members for the inclusion/exclusion criteria, the participants central line will be assessed by an 11 Blue BMT nurse every 12 hours, and they may be asked questions regarding their medical history during their stay on 11 Blue BMT. If a participant is discharged or transferred off of the 11 Blue BMT unit, they will no longer be included in the study and their central line maintenance will return to the UTSW Standard of Care. Participants in this study may be at risk for central line occlusion (a blood clot) which could require intervention to regain the free flow of fluids and use of the central line. The study team predicts there will be no increase in the rate of line occlusion when using Normal Saline Flushes only to maintain the free flow of fluids through participants central line. The study team also hopes the results of this study will help to improve patient outcomes by decreasing risk of infection, heparin associated complications, and costs.

142 participants in 2 patient groups

Heparin Group

Active Comparator group

Description:

Participants will receive the UTSW standard of of care for PICC line maintenance. All lumens of PICC line will be flushed w/ Heparin Flush every 8 hours. PICC line will be flushed with 10cc Normal Saline followed by 3cc Heparin Flush after administration of medication, blood products, or blood draws.

Treatment:

Drug: Heparin Group

Normal Saline Group

Experimental group

Description:

Participants will receive only Normal Saline for PICC line maintenance. All lumens of PICC line will be flushed every 24 hours with 10cc Normal Saline. PICC line will be flushed with 10cc Normal Saline after administration of medication, blood products, or blood draws.

Treatment:

Drug: Normal Saline Group
