CVC's have two or more lumens / ports what is each one used for
|
Distal = incompatible medication, colloids, viscous fluids
Medial= TNP Proximal= blood sampling, blood admin |
|
how do we prevent blood reflux
|
maintain positive pressure except for Groshong they have a slit or pressure sensitive valve
|
|
Methods to assist in aspirating blood
|
1. have pt. turn head toward the opposite shoulder
2. raise arm on the same sidwe ad CVC 3 have pat. turn side to side 4 have pt. sit up 5. have pt. cough 6. use the push-pause tech |
|
Air emobolism interventions
|
1 clamp catheter
2. position in left lateral trendenburg 3. admin 100% o2 4. take vital signs 5. notify md |
|
S/S of air embolism
|
dyspnea, tachypnea, cough - often with hemptoysis, substernal pain or chest pain when breathing, diaphoriesis, confusion, anxiety, feeling of impending boom, hypotension, decreased breath sounds, pleural friction rub
|
|
;removing of the CVC
|
Valsalva maneurver:
have patient take a deep breath - hold it with mouth closed and bear down or push like having a bowel movement for 10 sections |
|
how is contraindicated for the Valsalva maneuver
|
increased intracranial pressure, recent eye surgery, myocardial infarcation, experiencing bradycardia or respiratory distress
|
|
procedures for removing a non-tunneled central venous line
|
1 place pt supine or trendenlenburg position
2. remove dressing in aseptic manner 3. remove stiches 4. have pt take a deep breath, hold and bear down 4. pull back on catheter slowly/steadily 5. apply pressure fwith a 4x4 for 15 min. or until homeostasis is acquired 6. inspect central line for intacness 7. instruct pt. to remain supine for 15 min 8. inspect site for 1 hr for bleeding, pain, edema, warmth, redness 9 assess pat for SOB, dyspnea, altered mental status |
|
4 types of central lines
|
non-tunneled
tunneled PICC implanted ports |
|
where is the tip of the CVAD located
|
superior vena cava = right before the heart
|
|
non-tunneled facts
|
can stay in for a lengthy time
good for emergancies 1 to 4 lumens has the highest rate for risk for infection flushed q8hr with 10cc NS when not in use |
|
tunneled catheter facts
|
used for long term use or chronically ill
least change for infection d/t tunnel and cuff matures and the scar tissue anchors the cath w/in 7 to 10 days then no dressing necessary ideal for active patients |
|
PICC facts
|
inserted in peripheral vein nad threaded into the superior vena cava
used for all therapies/blood collection for pts requiring daily infusion therapies up to 6 mos can clot more easily high risk for infection no vaccum containers when drawing blood |
|
Imported port facts
|
out of sight
used for 2000 sticks best for chemo or antibiotics need a huber needle to access port change dressing q48 hours |
|
CATHETER RELATED SEPSIS S/S
|
sudden spike in temp
shoulder pain look for reddened area and purulent drainage notify physician |
|
catheter malfunction S?S
|
access a port and obtain blood return (not just pink tinged fluid) if not clamp, do not flush, notify physician
|
|
evravasion
|
admin of a vesicant substance into the tissues can have a disastrous outcome = fluid gets under the skin
|
|
infiltrate
|
inadvertent admin of non vesicant solution / medication into the surrounding tissues
|
|
phlebitis
|
infusion phlebitis is inflammatin of the vein first sign is tenderness at the insertion site
|
