Recall that the rationale for the initial flush was to ensure IV patency so that the medication would be administered via the correct route. The flush following the medication administration was to clear the extension tubing and to maintain patency of the venous access device until the next time it required access.\r\n\r\nIn this section we discuss flushing and locking of PVAD-short catheters and CVADs (PICCs and percutaneus non hemodialysis catheters) as part of routine care and maintenance.\u00a0 Flushing and locking of IVADs, CVAD hemodialysis lines, and tunnelled catheters require additional education and training beyond the scope of this textbook.\r\n\r\nIf IVs are not being infused, they are often locked. Locked lumens require care and maintenance to allow them to remain patent until the next time they are needed. PVAD-short cannulas that are locked are commonly referred to as a <em>saline lock<\/em> (Figure 8.21) . CVADs that are locked are referred to as being either <em>capped<\/em> or <em>locked<\/em>; for example \"a <em>locked<\/em> PICC,\" \"a <em>capped<\/em> percutaneous non hemodialysis CVAD,\" or \"a PICC with one <em>capped<\/em> lumen and two accessed lumens.\" (See Figure 8.6.)\r\n\r\n[caption id=\"attachment_6155\" align=\"aligncenter\" width=\"297\"]<a href=\"http:\/\/opentextbc.ca\/clinicalskills\/wp-content\/uploads\/sites\/82\/2015\/09\/DSC_0896.jpg\"><img class=\"wp-image-6155 \" src=\"https:\/\/pressbooks.bccampus.ca\/clinicalproceduresforsaferpatientcaretrubscn\/wp-content\/uploads\/sites\/472\/2015\/06\/DSC_0896-300x199.jpg\" alt=\"Saline lock (Max Plus end attached)\" width=\"297\" height=\"197\" \/><\/a> Figure 8.21 PVAD short saline lock with needleless cap[\/caption]\r\n\r\n[caption id=\"attachment_1704\" align=\"aligncenter\" width=\"297\"]<img class=\"wp-image-1704 \" src=\"https:\/\/pressbooks.bccampus.ca\/clinicalproceduresforsaferpatientcaretrubscn\/wp-content\/uploads\/sites\/472\/2018\/08\/PICC-300x225.jpg\" alt=\"\" width=\"297\" height=\"223\" \/> Figure 8.6 PICC with one capped lumen (blue) and two accessed lumens.[\/caption]\r\n\r\nRoutine flushing and locking of IV catheters is meant to prevent catheter occlusion (Goossens, 2015). Besides mechanical reasons, IV catheter occlusion can result from blood clot (fibrin) in the lumen or at the catheter tip and\/or build up of precipitates in the lumen from medications and parenteral nutrition. Flushing and locking protocols are meant to maintain patent lumens. 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).\r\n\r\nHistorically a <strong>positive pressure<\/strong> technique was used to prevent back flow of blood into the IV catheter; thus posing a risk of occlusion. Manual ways of achieving positive pressure include disconnecting the syringe from the needleless cap while still exerting pressure on the plunger during the last 0.5 ml. Another technique involves clamping the catheter while injecting the last 0.5 ml. Fast forward to the present and we now have technology to help us. Neutral displacement and positive pressure valves (caps) can be used and some IV catheters have valves built into their structure to prevent back flow of blood into the lumen. In addition, 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 (Goossens, 2015).\r\n\r\nUnderstanding the available IV equipment will direct the nurse to the proper flushing and locking protocols. This includes knowing 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).\r\n\r\nFlushing and locking protocols are developed based on knowledge of the IV catheters (the type, size, and structure) and the patient condition (prescribed IV medications). Check your agency guidelines for specifics, but know that some general guidelines do apply for PICC and percutaneous non hemodialysis CVAD flushing and locking procedures (Gorski et al., 2016):\r\n<ul>\r\n \t<li>Follow principles of asepsis to reduce risk of infection.<\/li>\r\n \t<li>Before use, CVADs should be checked for patency using a 10 ml or larger syringe containing saline.<\/li>\r\n \t<li>Patency is checked by aspirating. On a PICC, midline, and percutaneous non hemodialysis CVAD aspirating should reveal blood flashback into the tubing.<\/li>\r\n \t<li>Aspirating on a PVAD-short often does not result in blood flashback due to small size of the veins. As such, patency will be assessed during the forward flush observing for resistance, leaking, and pain at the site.<\/li>\r\n \t<li>10 ml syinges of 0.9% NS should be used to flush CVADs to reduce the risk of catheter fracture.<\/li>\r\n \t<li>Always follow the manufacturer\u2019s instructions when using needleless caps, as different techniques are required for different caps.<\/li>\r\n \t<li>The volume of the flush solution will depend on the volume of the catheter and any add on devices. The goal of locking an IV line is to fill the catheter entirely and preserve its integrity for future use (Goossens, 2014).<\/li>\r\n \t<li>The solution and frequency depends on whether the catheter is open-ended or valved, and what solution is being infused (i.e., blood, PN, etc.).<\/li>\r\n \t<li>Follow the agency guidelines. Recognize that guidelines for specific patient populations may vary.<\/li>\r\n \t<li>When using heparin, use the lowest possible dose that will maintain patency. Heparin always presents risk of bleeding. The goal is to heparinize the line not the patient.<\/li>\r\n \t<li>Some lines require the heparin locking solution to be removed prior to using the line.<\/li>\r\n \t<li>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.<\/li>\r\n \t<li>Closed-ended or valved CVCs usually have no external clamps. Open-ended or non-valved CVCs usually have external clamps (non-removable) present. Check the patient chart.<\/li>\r\n \t<li>Cleanse the needleless cap before attaching and after detaching any syringe to reduce risk of infection.<\/li>\r\n<\/ul>\r\nTable 8.11 is a sample of a flushing and locking protocol. Your agency should have a protocol available for you to follow.

Recall that the rationale for the initial flush was to ensure IV patency so that the medication would be administered via the correct route. The flush following the medication administration was to clear the extension tubing and to maintain patency of the venous access device until the next time it required access.<\/p>\n<p>In this section we discuss flushing and locking of PVAD-short catheters and CVADs (PICCs and percutaneus non hemodialysis catheters) as part of routine care and maintenance.\u00a0 Flushing and locking of IVADs, CVAD hemodialysis lines, and tunnelled catheters require additional education and training beyond the scope of this textbook.<\/p>\n<p>If IVs are not being infused, they are often locked. Locked lumens require care and maintenance to allow them to remain patent until the next time they are needed. PVAD-short cannulas that are locked are commonly referred to as a <em>saline lock<\/em> (Figure 8.21) . CVADs that are locked are referred to as being either <em>capped<\/em> or <em>locked<\/em>; for example &#8220;a <em>locked<\/em> PICC,&#8221; &#8220;a <em>capped<\/em> percutaneous non hemodialysis CVAD,&#8221; or &#8220;a PICC with one <em>capped<\/em> lumen and two accessed lumens.&#8221; (See Figure 8.6.)<\/p>\n<figure id=\"attachment_6155\" aria-describedby=\"caption-attachment-6155\" style=\"width: 297px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/opentextbc.ca\/clinicalskills\/wp-content\/uploads\/sites\/82\/2015\/09\/DSC_0896.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-6155\" src=\"https:\/\/pressbooks.bccampus.ca\/clinicalproceduresforsaferpatientcaretrubscn\/wp-content\/uploads\/sites\/472\/2015\/06\/DSC_0896-300x199.jpg\" alt=\"Saline lock (Max Plus end attached)\" width=\"297\" height=\"197\" \/><\/a><figcaption id=\"caption-attachment-6155\" class=\"wp-caption-text\">Figure 8.21 PVAD short saline lock with needleless cap<\/figcaption><\/figure>\n<figure id=\"attachment_1704\" aria-describedby=\"caption-attachment-1704\" style=\"width: 297px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1704\" src=\"https:\/\/pressbooks.bccampus.ca\/clinicalproceduresforsaferpatientcaretrubscn\/wp-content\/uploads\/sites\/472\/2018\/08\/PICC-300x225.jpg\" alt=\"\" width=\"297\" height=\"223\" srcset=\"https:\/\/pressbooks.bccampus.ca\/clinicalproceduresforsaferpatientcaretrubscn\/wp-content\/uploads\/sites\/472\/2018\/08\/PICC-300x225.jpg 300w, https:\/\/pressbooks.bccampus.ca\/clinicalproceduresforsaferpatientcaretrubscn\/wp-content\/uploads\/sites\/472\/2018\/08\/PICC-65x49.jpg 65w, https:\/\/pressbooks.bccampus.ca\/clinicalproceduresforsaferpatientcaretrubscn\/wp-content\/uploads\/sites\/472\/2018\/08\/PICC-225x169.jpg 225w, https:\/\/pressbooks.bccampus.ca\/clinicalproceduresforsaferpatientcaretrubscn\/wp-content\/uploads\/sites\/472\/2018\/08\/PICC-350x263.jpg 350w, https:\/\/pressbooks.bccampus.ca\/clinicalproceduresforsaferpatientcaretrubscn\/wp-content\/uploads\/sites\/472\/2018\/08\/PICC.jpg 600w\" sizes=\"auto, (max-width: 297px) 100vw, 297px\" \/><figcaption id=\"caption-attachment-1704\" class=\"wp-caption-text\">Figure 8.6 PICC with one capped lumen (blue) and two accessed lumens.<\/figcaption><\/figure>\n<p>Routine flushing and locking of IV catheters is meant to prevent catheter occlusion (Goossens, 2015). Besides mechanical reasons, IV catheter occlusion can result from blood clot (fibrin) in the lumen or at the catheter tip and\/or build up of precipitates in the lumen from medications and parenteral nutrition. Flushing and locking protocols are meant to maintain patent lumens. 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).<\/p>\n<p>Historically a <strong>positive pressure<\/strong> technique was used to prevent back flow of blood into the IV catheter; thus posing a risk of occlusion. Manual ways of achieving positive pressure include disconnecting the syringe from the needleless cap while still exerting pressure on the plunger during the last 0.5 ml. Another technique involves clamping the catheter while injecting the last 0.5 ml. Fast forward to the present and we now have technology to help us. Neutral displacement and positive pressure valves (caps) can be used and some IV catheters have valves built into their structure to prevent back flow of blood into the lumen. In addition, 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 (Goossens, 2015).<\/p>\n<p>Understanding the available IV equipment will direct the nurse to the proper flushing and locking protocols. This includes knowing 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).<\/p>\n<p>Flushing and locking protocols are developed based on knowledge of the IV catheters (the type, size, and structure) and the patient condition (prescribed IV medications). Check your agency guidelines for specifics, but know that some general guidelines do apply for PICC and percutaneous non hemodialysis CVAD flushing and locking procedures (Gorski et al., 2016):<\/p>\n<ul>\n<li>Follow principles of asepsis to reduce risk of infection.<\/li>\n<li>Before use, CVADs should be checked for patency using a 10 ml or larger syringe containing saline.<\/li>\n<li>Patency is checked by aspirating. On a PICC, midline, and percutaneous non hemodialysis CVAD aspirating should reveal blood flashback into the tubing.<\/li>\n<li>Aspirating on a PVAD-short often does not result in blood flashback due to small size of the veins. As such, patency will be assessed during the forward flush observing for resistance, leaking, and pain at the site.<\/li>\n<li>10 ml syinges of 0.9% NS should be used to flush CVADs to reduce the risk of catheter fracture.<\/li>\n<li>Always follow the manufacturer\u2019s instructions when using needleless caps, as different techniques are required for different caps.<\/li>\n<li>The volume of the flush solution will depend on the volume of the catheter and any add on devices. The goal of locking an IV line is to fill the catheter entirely and preserve its integrity for future use (Goossens, 2014).<\/li>\n<li>The solution and frequency depends on whether the catheter is open-ended or valved, and what solution is being infused (i.e., blood, PN, etc.).<\/li>\n<li>Follow the agency guidelines. Recognize that guidelines for specific patient populations may vary.<\/li>\n<li>When using heparin, use the lowest possible dose that will maintain patency. Heparin always presents risk of bleeding. The goal is to heparinize the line not the patient.<\/li>\n<li>Some lines require the heparin locking solution to be removed prior to using the line.<\/li>\n<li>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.<\/li>\n<li>Closed-ended or valved CVCs usually have no external clamps. Open-ended or non-valved CVCs usually have external clamps (non-removable) present. Check the patient chart.<\/li>\n<li>Cleanse the needleless cap before attaching and after detaching any syringe to reduce risk of infection.<\/li>\n<\/ul>\n<p>Table 8.11 is a sample of a flushing and locking protocol. Your agency should have a protocol available for you to follow.
