IV cannulas can become occluded from blood clots (fibrin) and \/ or build up of precipitates from meds, IV fluids including PN.\u00a0 In addition, proper flushing and locking might eliminate potential nesting material for microorganisms and as such reduce the risk of catheter related blood stream infections (Ferroni et al., 2014).\u00a0<\/em><em>The nurse needs to know what kind of venous access device the patient has, what solutions are being infused and how often, if the device is peripheral or centrally located, the number of lumens, and if the lumens are open (non-valved) or closed (valved).\u00a0<\/em><em>Generally <\/em><em>CVC<\/em><em> lumens are flushed before and after all IV meds. <\/em><em>CVC<\/em><em> lumens that are in use <\/em><em>AND<\/em><em> those not in use are routinely flushed. It is important to follow agency guidelines.<\/em>\r\n\r\n<em><span style=\"text-decoration: underline\">Think about the structure of the IV cannula:\u00a0<\/span>A valved CVAD has an internal mechanism to prevent blood reflux thus the use of an anticoagulant (heparin) is not necessary as part of the locking procedure. A valved CVAD has an internal mechanism to prevent blood reflux thus the use of an anticoagulant (heparin) is not necessary as part of the locking procedure.<\/em>\r\n\r\n<em><span style=\"text-decoration: underline\">Think about what guidelines are available in your agency:<\/span> Agencies should have flushing protocols available to provide the nurse with guidance in relation to volume and frequency of flushing.<\/em>\r\n\r\n<em><span style=\"text-decoration: underline\">Think about add on IV equipment and what maintenance they need:<\/span> The nurse must also understand the equipment available to them. Ie. what kind of needleless cap is being used. Neutral displacement and positive pressure valves (caps) can be used. Some syringes are specifically designed and if used correctly (remove the syringe before bottoming out) create the necessary positive pressure to prevent blood reflux into the catheter. This is important if the lumen will not have a continuous infusion running following the flush.<\/em>\r\n\r\n&nbsp;\r\n\r\n<em>Some general guidelines include:<\/em>\r\n<ul>\r\n \t<li><em>Before use, CVADs should be checked for patency using a 10 ml or larger syringe containing saline.<\/em><\/li>\r\n \t<li><em>Patency is checked by aspirating. On a PICC, midline, and percutaneous non hemodialysis CVAD aspirating should reveal blood flashback into the tubing.<\/em><\/li>\r\n \t<li><em>10 ml syinges of 0.9% NS should be used to flush CVADs to reduce the risk of catheter fracture. Smaller syringes have higher <\/em><em>PSI<\/em><em> thus risk of catheter damage.<\/em><\/li>\r\n \t<li><em>Always follow the manufacturer\u2019s instructions when using needleless caps, as different techniques are required for different caps.<\/em><\/li>\r\n \t<li><em>The volume of the flush solution will depend on the volume of the catheter and any add on devices.<\/em><\/li>\r\n \t<li><em>Turbulent flush is a rapid stop-start or push-pause technique that is meant to clear the catheter of blood or drugs that may adhere to the inner lumen of the catheter.<\/em><\/li>\r\n \t<li><em>Cleanse the needleless cap before attaching and after detaching any syringe to reduce risk of infection.<\/em><\/li>\r\n \t<li><em>If no aspirate,\u00a0reposition the patient's arm (for PICC) or neck (other CVCs); assess the line for kinks; request patient take deep breaths, turn head and cough and\/or perform Valsalva maneuver. If still no aspirate, change positive \/ neutral pressure cap. If still no aspirate consult PICC \/ IV team for possible declotting. Do not forward flush due to risk of dislodging thrombus from the lumen.<\/em><\/li>\r\n \t<li><em>Always clamp after removing syringe from the needleless cap. Positive displacement occurs in a neutral displacement cap when the syringe is disconnected from the cap before the syringe is completely emptied.<\/em><\/li>\r\n<\/ul>\r\nSample flushing and Locking Protocol\r\n<table>\r\n<tbody>\r\n<tr>\r\n<td><em>Vascular Access Device<\/em><\/td>\r\n<td><em>Flushing<\/em><em> and Locking Solution, and Volume<\/em><\/td>\r\n<td><em>Frequency<\/em><\/td>\r\n<\/tr>\r\n<tr>\r\n<td><em>CVAD, <strong>non-valved <\/strong>(e.g., percutaneous, tunneled, PICC)<\/em><\/td>\r\n<td><em>Flush: 10 to 20 ml, 0.9% sodium chloride followed by<\/em>\r\n\r\n<em>Lock: Heparin 3 ml of 100 units\/ml<\/em><\/td>\r\n<td><em>Flush before and after each IV medication or access.<\/em>\r\n\r\n<em>When retrograde blood observed<\/em>\r\n\r\n<em>Lock after each access, or weekly if not in use.<\/em><\/td>\r\n<\/tr>\r\n<\/tbody>\r\n<\/table>\r\nSources:\r\n\r\nAnderson, R.

IV cannulas can become occluded from blood clots (fibrin) and \/ or build up of precipitates from meds, IV fluids including PN.\u00a0 In addition, proper flushing and locking might eliminate potential nesting material for microorganisms and as such reduce the risk of catheter related blood stream infections (Ferroni et al., 2014).\u00a0<\/em><em>The nurse needs to know what kind of venous access device the patient has, what solutions are being infused and how often, if the device is peripheral or centrally located, the number of lumens, and if the lumens are open (non-valved) or closed (valved).\u00a0<\/em><em>Generally <\/em><em>CVC<\/em><em> lumens are flushed before and after all IV meds. <\/em><em>CVC<\/em><em> lumens that are in use <\/em><em>AND<\/em><em> those not in use are routinely flushed. It is important to follow agency guidelines.<\/em><\/p>\n<p><em><span style=\"text-decoration: underline\">Think about the structure of the IV cannula:\u00a0<\/span>A valved CVAD has an internal mechanism to prevent blood reflux thus the use of an anticoagulant (heparin) is not necessary as part of the locking procedure. A valved CVAD has an internal mechanism to prevent blood reflux thus the use of an anticoagulant (heparin) is not necessary as part of the locking procedure.<\/em><\/p>\n<p><em><span style=\"text-decoration: underline\">Think about what guidelines are available in your agency:<\/span> Agencies should have flushing protocols available to provide the nurse with guidance in relation to volume and frequency of flushing.<\/em><\/p>\n<p><em><span style=\"text-decoration: underline\">Think about add on IV equipment and what maintenance they need:<\/span> The nurse must also understand the equipment available to them. Ie. what kind of needleless cap is being used. Neutral displacement and positive pressure valves (caps) can be used. Some syringes are specifically designed and if used correctly (remove the syringe before bottoming out) create the necessary positive pressure to prevent blood reflux into the catheter. This is important if the lumen will not have a continuous infusion running following the flush.<\/em><\/p>\n<p>&nbsp;<\/p>\n<p><em>Some general guidelines include:<\/em><\/p>\n<ul>\n<li><em>Before use, CVADs should be checked for patency using a 10 ml or larger syringe containing saline.<\/em><\/li>\n<li><em>Patency is checked by aspirating. On a PICC, midline, and percutaneous non hemodialysis CVAD aspirating should reveal blood flashback into the tubing.<\/em><\/li>\n<li><em>10 ml syinges of 0.9% NS should be used to flush CVADs to reduce the risk of catheter fracture. Smaller syringes have higher <\/em><em>PSI<\/em><em> thus risk of catheter damage.<\/em><\/li>\n<li><em>Always follow the manufacturer\u2019s instructions when using needleless caps, as different techniques are required for different caps.<\/em><\/li>\n<li><em>The volume of the flush solution will depend on the volume of the catheter and any add on devices.<\/em><\/li>\n<li><em>Turbulent flush is a rapid stop-start or push-pause technique that is meant to clear the catheter of blood or drugs that may adhere to the inner lumen of the catheter.<\/em><\/li>\n<li><em>Cleanse the needleless cap before attaching and after detaching any syringe to reduce risk of infection.<\/em><\/li>\n<li><em>If no aspirate,\u00a0reposition the patient&#8217;s arm (for PICC) or neck (other CVCs); assess the line for kinks; request patient take deep breaths, turn head and cough and\/or perform Valsalva maneuver. If still no aspirate, change positive \/ neutral pressure cap. If still no aspirate consult PICC \/ IV team for possible declotting. Do not forward flush due to risk of dislodging thrombus from the lumen.<\/em><\/li>\n<li><em>Always clamp after removing syringe from the needleless cap. Positive displacement occurs in a neutral displacement cap when the syringe is disconnected from the cap before the syringe is completely emptied.<\/em><\/li>\n<\/ul>\n<p>Sample flushing and Locking Protocol<\/p>\n<table>\n<tbody>\n<tr>\n<td><em>Vascular Access Device<\/em><\/td>\n<td><em>Flushing<\/em><em> and Locking Solution, and Volume<\/em><\/td>\n<td><em>Frequency<\/em><\/td>\n<\/tr>\n<tr>\n<td><em>CVAD, <strong>non-valved <\/strong>(e.g., percutaneous, tunneled, PICC)<\/em><\/td>\n<td><em>Flush: 10 to 20 ml, 0.9% sodium chloride followed by<\/em><\/p>\n<p><em>Lock: Heparin 3 ml of 100 units\/ml<\/em><\/td>\n<td><em>Flush before and after each IV medication or access.<\/em><\/p>\n<p><em>When retrograde blood observed<\/em><\/p>\n<p><em>Lock after each access, or weekly if not in use.<\/em><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Sources:<\/p>\n<p>Anderson, R.
