Catheter failure can result in treatment interruption, additional procedures, loss of valuable vascular access sites and increased stress for patients, families and clinical teams.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Importantly, many complications do not occur suddenly. They often develop gradually, with subtle warning signs appearing before significant clinical deterioration. For this reason, complication prevention should be considered a continuous process rather than a response to problems once they occur.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This article provides a practical guide to the most common complications associated with neonatal PICCs and Midlines, including risk factors, early warning signs and preventative strategies that can support safer vascular access practice.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">A Practical Approach to Complication Prevention<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Successful complication prevention begins with a simple principle:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The best complication is the one that never occurs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Clinicians can reduce risk by focusing on:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Appropriate device selection<\/li>\n\n\n\n<li>Careful vein assessment<\/li>\n\n\n\n<li>Optimal insertion technique<\/li>\n\n\n\n<li>Effective securement<\/li>\n\n\n\n<li>Routine maintenance<\/li>\n\n\n\n<li>Vigilant monitoring<\/li>\n\n\n\n<li>Timely removal when devices are no longer required<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Risk Factors<\/strong> <strong>\u2192 Early Warning Signs<\/strong> <strong>\u2192 Prevention Strategies<\/strong> <strong>\u2192 Escalation Considerations<\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h2 class=\"wp-block-heading\">Complication 1: Catheter Occlusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why It Matters<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Occlusion is one of the most common causes of catheter dysfunction and unplanned device removal in vascular access practice.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Occlusions may be:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Partial<\/li>\n\n\n\n<li>Intermittent<\/li>\n\n\n\n<li>Complete<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Reduced catheter function can delay therapy, increase manipulation of the device and ultimately necessitate replacement.<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-regular\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Risk Factors<\/strong><\/td><td><strong>Early Warning Signs<\/strong><\/td><td><strong>Prevention Strategies<\/strong><\/td><td><strong>Escalate If<\/strong><\/td><\/tr><tr><td>-Inadequate flushing

flushing protocols.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Complication 2: Catheter Migration<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why It Matters<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Migration occurs when the catheter position changes after insertion.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Even relatively small changes in external catheter length may alter catheter tip location and affect device performance.<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-regular\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Risk Factors<\/strong><\/td><td><strong>Early Warning Signs<\/strong><\/td><td><strong>Prevention Strategies<\/strong><\/td><td><strong>Escalate If<\/strong><\/td><\/tr><tr><td>-Inadequate

Matters<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Accidental dislodgement remains a major cause of unplanned catheter removal within neonatal units.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Each unplanned removal may expose the infant to additional vascular access procedures and further vessel trauma.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table

Matters<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Phlebitis refers to inflammation of the vessel wall and may occur with vascular access devices.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Although often mild initially, untreated phlebitis can compromise catheter function and patient comfort.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Risk Factors<\/strong><\/td><td><strong>Early Warning Signs<\/strong><\/td><td><strong>Prevention Strategies<\/strong><\/td><td><strong>Escalate

class=\"wp-block-heading\">Complication 5: Infiltration and Extravasation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why It Matters<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Infiltration occurs when non-vesicant solutions enter surrounding tissue, while extravasation involves the leakage of vesicant or potentially harmful substances into tissue.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Although less common with well-functioning PICCs and Midlines, these complications can result in significant tissue injury.<\/p>\n\n\n\n<figure

class=\"wp-block-paragraph\"><strong>Why It Matters<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Catheter-associated infections remain among the most significant vascular access complications encountered in neonatal care. They have the potential to lead to a Catheter Related Blood Stream Infection (CRBSI) and in severe cases Sepsis.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Prevention requires attention throughout the catheter&#8217;s lifespan rather than focusing solely on insertion.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Risk Factors<\/strong><\/td><td><strong>Early Warning Signs<\/strong><\/td><td><strong>Prevention Strategies<\/strong><\/td><td><strong>Escalate If<\/strong><\/td><\/tr><tr><td>-Poor hand hygiene<br>-Dressing disruption<br>-Frequent catheter manipulation<br>-Breaches in aseptic technique<br>-Prolonged catheter dwell times<\/td><td>-Temperature instability<br>-Unexplained clinical deterioration<br>-Local redness<br>-Drainage at the insertion site<br>-Increased respiratory support needs<br>Reduced feeding tolerance<\/td><td>-Adhere to hand hygiene protocols<br>-Use Aseptic Non-Touch Technique (ANTT\u00ae)<br>-Maintain dressing integrity<br>-Minimise unnecessary access<br>-Perform routine site assessment<\/td><td>-Infection is suspected<br>-Systemic signs emerge<br>-Local site changes worsen<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Complication 7: Thrombosis<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why It Matters<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Thrombosis may affect both catheter performance and long-term vessel health.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Although some cases are asymptomatic, others may compromise vascular access and increase clinical complexity.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Risk Factors<\/strong><\/td><td><strong>Early Warning Signs<\/strong><\/td><td><strong>Prevention Strategies<\/strong><\/td><td><strong>Escalate If<\/strong><\/td><\/tr><tr><td>-Vessel trauma<br>-Large catheter-to-vessel ratio<br>-Catheter movement<br>-Prolonged dwell time<br>-Reduced blood flow around the catheter<\/td><td>-Unexplained catheter dysfunction<br>-Limb swelling<br>-Changes in catheter performance<br>-Recurrent occlusion events<\/td><td>-Prioritise vessel assessment<br>-Select appropriately sized catheters<br>-Optimise securement<br>-Monitor performance trends<br>-Investigate recurrent dysfunction promptly<\/td><td>-Thrombosis is suspected<br>-Limb swelling develops<br>-Persistent performance issues occur<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Red Flags Requiring Immediate Escalation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The following findings should trigger urgent review according to local policy:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udd34 Rapid or unexplained swelling<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udd34 Suspected extravasation<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udd34 Significant catheter migration<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udd34 Catheter-related infection concerns<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udd34 Loss of catheter function<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udd34 Catheter damage or rupture<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\ud83d\udd34 Unexplained limb swelling<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Clinical Scenario<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Recognising a Developing Complication<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A 30-week infant has a Midline that has been functioning well for seven days.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During a routine assessment:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Infusions remain running.<\/li>\n\n\n\n<li>The dressing is intact.<\/li>\n\n\n\n<li>Mild resistance is noted during flushing.<\/li>\n\n\n\n<li>Two infusion pump alarms have occurred during the previous shift.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Although therapy continues successfully, these findings may represent early catheter dysfunction.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Recommended action:<\/strong> Further assessment should occur before complete occlusion develops. Waiting until the catheter becomes non-functional may result in avoidable device loss.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Key Practice Points<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\u2705 Assess every catheter at every interaction.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2705 Monitor trends, not just individual observations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2705 Investigate subtle changes early.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2705 Standardise escalation pathways.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2705 Protect vessel health through proactive intervention.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2705 Consider complications before they occur, not after.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2705 Treat every unplanned removal as a learning opportunity.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Complications associated with neonatal PICCs and Midlines cannot always be prevented, but many can be anticipated, recognised early and managed before they result in device failure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A structured approach that combines careful assessment, routine monitoring, effective maintenance and prompt escalation can help preserve vascular access, minimise treatment interruption and improve patient outcomes. Ultimately, successful complication prevention is a key component of vessel preservation and should be embedded within every stage of the neonatal vascular access pathway.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Next Article:<\/p>\n\n\n\n<div class=\"wp-block-media-text alignwide is-stacked-on-mobile is-vertically-aligned-center is-image-fill-element has-white-color has-text-color has-background has-link-color wp-elements-1\" style=\"background-color:#004431;grid-template-columns:20% auto\"><figure class=\"wp-block-media-text__media\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"http:\/\/campusvygon.com\/uk\/wp-content\/uploads\/sites\/9\/2026\/04\/shutterstock_Neonate-VA-1024x683.jpg\" alt=\"\" class=\"wp-image-53817 size-full\" style=\"object-position:50% 50%\" srcset=\"http:\/\/campusvygon.com\/uk\/wp-content\/uploads\/sites\/9\/2026\/04\/shutterstock_Neonate-VA-980x653.jpg 980w, http:\/\/campusvygon.com\/uk\/wp-content\/uploads\/sites\/9\/2026\/04\/shutterstock_Neonate-VA-480x320.jpg 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1024px, 100vw\" \/><\/figure><div class=\"wp-block-media-text__content\">\n<h2 class=\"wp-block-heading has-white-color has-text-color has-background\" style=\"background-color:#004431;font-size:22px\"><strong>Neonatal PICC and Midline Removal: When Is the Right Time?<\/strong><\/h2>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n<div class=\"wp-block-button is-style-fill\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/campusvygon.com\/uk\/neonatology\/neonatal-vascular-access-a-practical-guide-to-piccs-and-midlines\/neonatal-picc-and-midline-removal-when-is-the-right-time\/\">Learn more<\/a><\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Supporting Materials<\/strong><\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>Sharpe EL, Wyckoff MM, Pettit J, et al. <em>Peripherally Inserted Central Catheters: Guideline for Practice<\/em>. 4th ed.
