Central venous catheter (CVC)

Central line
Catheter inserted into centrally located vein
Usually subclavian***
Line

1

Crystalloid

Non-colloid (salts), electrolyte solution (w/ potential to form crystals)

Restore vascular volume

Example- Normal Saline (NS 0.9%)

2

Portacath

Implanted Ports
Surgically placed under skin -> assess vascular system internally
SINGLE SIGHT to inject medications, fluids or take blood samples
Used for months; tunnel cancer unit

3

Peripherally Inserted Central Canal (PICC)

-Performed by specialized Nurse
-catheter threaded through peripheral vein to the Superior Vena Cava
-make sure to check under sleeve
-up to 6 weeks

4

Vascular Access Device (VAD)

Catheters, cannulas, or infusion ports
Designed for long term repeated assess to vascular system

5

Extravasation

(vesicant solution) administered into surrounding tissue
Capable of ->tissue injury/ destruction ( blistering of skin)

Examples: chemo meds, pressor agents (dopamine), K+Cl-, Zosyn, dilantent

6

Infiltration

NONvesicant admin. into surrounding tissue
Swelling, puffy, leaking at puncture site

7

Delayed extravasation

S/s 48+ hrs post med admin

8

S/s of Septicemia

Gradual/ sudden rise in T
Shaking chills
Tachycardia
HA
Gastric symptoms
CAN -> SEPTIC SHOCK

9

Tx of Septicemia

Relocate IV site using different lot # for ALL medical equipment used

Collect and culture specimen

10

Air embolism

Air inadvertently enters venous system
More frequent w/ central lines

11

Tx Air Embolism

- Place pt on LEFT side w/ HOB flat - trap air in rt atrium
- Administer 100% O2
- Cariocentesis may be required to aspirate air

12

ICF

Intracellular fluid
2/3 body's water weight
Kept in cells by proteins

13

Interstitial

Fluid between cells/ surrounds cells

14

ECF

Extracellular Fluids
1/3 water weight
Includes Intravascular, Interstitial, Transcellular, &Lymph

15

Serum osmolarity

Concentration of body fluids
Normal range 280-300mOsm/kg
Glucose = major determinant

16

Fluid intake/ output

General I/O a day (2500mL)
Ht, wt, gender impact rate of fluid

17

PICC is good for

~six weeks
