![]() ![]() Power PICCs of 4Fr single lumen, 5Fr single or double lumen and 6Fr single or double lumen can be power injected at 5 mls/sec and a maximum power injector pressure setting of 300 psi. Refer to the marking on the hub of the catheter to determine the maximum rate of injection and to choose the correct lumen for power injection. The Power PICC is a purple central venous catheter that has been approved by the FDA for power injection of contrast in adults and children. The PowerPICC line by BARD Access Systems.These lines include, but are not limited to the following: and should only be be used according to manufacturer's guidelines in the presence of appropriately trained personnel. PICCs that are power injectable are clearly marked "power injectable" and have a maximum flow rate printed on the catheter lumen or hub itself. If the patient complains of pain the injection should be stopped and the patient examined for signs of extravasation.Ģ) PICCs (peripherally inserted central catheters) If extravasation is detected, the injection is stopped immediately. If no problem is encountered during the initial injection, the individual monitoring the injection exits the CT scan room before the scanning begins. ![]() ![]() A critical step in preventing significant extravasation is direct monitoring of the venipuncture site by palpation during the initial portion of the contrast medium injection. Standard procedures should be used to clear the syringe and pressure tubing of air before connecting to the catheter. A saline test flush may be used to test the power injection. in pediatrics) to suit the smaller bore catheter.Ī small peripheral line IV of 24 gauge, may only be used for contrast by hand injection.īefore initiating the injection, the position of the catheter tip should be checked for venous backflow by withdrawing blood and flushing with normal saline. When a 22-gauge catheter is used, the technologist should adjust the injection rate to < 3.0 cc/sec in adults (2.0 cc/sec. Although 22-gauge catheters may be able to tolerate flow rates up to 5 ml/sec, the 20-gauge or larger catheter is preferable for flow rates of 3 ml/sec or higher. A peripheral intravenous line (20 gauge) in the antecubital or forearm area is preferred when power injections are needed in adults. The follow flowchart will assist in the decision of obtaining proper venous access for contrast administration.ĭoctors, nurses and Radiology technologists can insert peripheral IV catheters in the adult arm for the purpose of contrast administration. However other routes may need to be used and each is considered separately below. ![]() A short peripheral IV catheter in the antecubital or forearm area is the preferred route for contrast administration. When the proper technique is used, contrast medium can safely be administered intravenously by power injector, at high-flow rates of up to 5 mls/second. Proper technique is used to avoid the potentially serious complications of contrast media extravasation and/or air embolism. Safe intravenous access, for the injection of intravenous contrast, is vital in obtaining high quality contrast enhanced or angiographic studies.
