Administration of intravenous therapy using a cannula , relieves the patient of multiple punctures, helps maintain a continuous intravenous line , continuous infusion , bolus administration , etc. .
After each injection was washed with dilute heparin solution or normal saline to prevent clotting . If the diluted solution was washed with heparin , to the heparin treatment , before each administration of the other drug solution is washed first with normal saline , heparin in the event that it is compatible with the medication to be administered .
Materials needed :
- medication prescribed and, if appropriate , the infusion set where the infusion is about
- alcohol pads 3 ml syringe
- normal saline solution
- fixator or plaster
- dilute solution of heparin
- check medication
- wash hands
- heparin dilution was prepared ( can be prepared with 10 to 100 units per ml ) and is drawn into the syringe, 3 ml
- the stem or disinfected rubber vial stopper
- perfusions attached to the infusion bag and remove the air, or pull the substance in the vial or ampoule into the syringe.
confirming patient identity
disinfected with a pad fortified cannula end , where it will attach syringe or perfusions
first aspirate the syringe to check if there is blood. If there cannula is correctly positioned and is permeable , if blood appears in suction , apply a tourniquet , not very closely , over the place where cannula , take about a minute and then
draws again. If blood still does not appear , loosen the tourniquet and inject a few ml of normal saline . If you encounter resistance to injection will not force, but will dilute heparin . If you feel resistance, then administer normal saline solution (to wash the traces of heparin may be incompatible with some drugs ) , noting carefully if you experience pain or signs of infiltration of the substance. However, if pain occurs , signs of resistance to injection and infiltration is observed , remove the catheter and will mount a new one.
after the administration of medication by the syringe , the solution is washed with normal saline and then diluted heparin , so as not to form thrombi
if adminstrează infusion on central line will adapt perfusions the central line will adjust the flow rate and , after removal , proceed in the same way that the injection syringe .
Special considerations :
must be administered if both infusion and medication compatible or not, establish an intravenous line secondary that will attach to the primary . Thus, if the substances are compatible and wants to go in parallel , the two solutions will be at the same level and will adjust the flow rate . If the patient has an intravenous line continues to be maintained and must be administered a substance that is not compatible with that infusion will establish the substance secondary venous line located above the primary and the secondary will only start at the end of the administration of restart the maintenance infusion .
remains functional even if the cannula should be changed to 48-72 hours , changing the insertion site .
