GENERAL INJECTION GUIDELINES
1. Always test line first with 10 cc NS rapid injection and flush line with 20 cc NS after injection 2. Stay in room after injection to ensure no extravasation 3. EJ: MANUALLY inject in emergency situations if no other line available. Avoid injecting if possible. 4. Triple Lumen central venous catheter Brown port can tolerate 3.5cc/s max and can be used for angio studies Can only power inject through brown port for angio study if TPN not running White/blue ports can handle 1.7cc/s max, only hand inject through white/blue ports! 5. Never inject leg/ foot. Hands ok with slow injection 6. Raise arm up onto scanner to ensure adequate contrast flow 7. Increase flow rates for larger patients 8. Decrease flow rates for smaller patients with fragile veins 9. MEDIPORT – FLUSH AFTER! GAUGES AND MAXIMUM INJECTION RATES GAUGE RATE cc/sec 24 (yellow) 1.5-1.7 22 (blue) 2.0 – 3.0 20 (pink) 3.0-4.0 (really up to 5.0) 18 (green) up to 5.0 Power PICC (purple) First check manufacturer (if in doubt if it is a power picc, do hand injection) if Power PICC (purple), follow manufacturer's max allowed injection rate MediPort First check manufacturer (if in doubt if it it is a power port, do hand injection) if Power PORT to be injected at high rate ( i.e. PE study), you need SPECIAL NEEDLE access GAD CONTRAST & DOSE eGFR>45 routine agent Magnevist, dosed approximately 2 cc/kg~1 cc/lb, max 20cc eGFR<45 Follow departmental guidelines IODINATED CONTRAST & DOSAGES Isovue 300 Intravenous contrast is the routine agent Chest/Abdomen/Pelvis (not PE/dissection) GAUGE 22 20 RATE 1.5-1.7 1.7-2.0 (3.0) VOLUME 100 100 DELAY Chest 25 sec, A/P 70 sec Abdomen/Pelvis Routine GAUGE 22 20 RATE 1.5-1.7 2.0-2.5 VOLUME 100 100 DELAY 70-75 seconds Abdomen/Pelvis Angio GAUGE 20 18 RATE 3.0 3.5-4.0 VOLUME 100 100 DELAY 25 seconds or SureStart PE/Dissection GAUGE 18 20*** RATE 3.5-4.0 2.5-3.0 VOLUME 140 DELAY SureStart, Dissection is appxm 20-24s, PE is 16s If only 20 Gauge is available, study may be limited.
