Complications of IV Line Removal

Introduction to Risks

Patient removal of IV lines can cause significant complications, including bleeding, air embolism, catheter embolism, and infection, potentially leading to serious morbidity or mortality, as noted by the American Society of Anesthesiologists 1
The risk of these complications can be mitigated with proper removal techniques and patient education, according to the American College of Radiology 2

Firm digital pressure should be applied for at least 5 minutes after IV removal to prevent bleeding, as recommended by the American Society of Anesthesiologists 1
Risk factors for excessive bleeding include coagulopathy, larger catheter size, and central venous access devices, as identified by the American Society of Anesthesiologists 1 and the European Society for Clinical Nutrition and Metabolism 3
The strength of evidence for these risk factors is moderate to high, based on studies published in Anaesthesia and Clinical Nutrition 1, 3
Routine reversal of coagulopathy is only necessary if platelet count <50 × 10⁹/L, aPTT >1.3 times normal, or INR >1.8, as recommended by the American Society of Anesthesiologists 1

Air embolism can occur during IV removal and may be fatal, with an incidence of up to 0.8%, as reported by the American Society of Anesthesiologists 1
Presentation of air embolism ranges from subtle neurological, respiratory, or cardiovascular signs to shock, loss of consciousness, and cardiac arrest, according to the American Society of Anesthesiologists 1
Prevention of air embolism requires proper removal techniques, including patient positioning, application of occlusive dressings, and head-down positioning with left lateral tilt if air embolism is suspected, as recommended by the American Society of Anesthesiologists 1

The risk of catheter fragment embolization is higher during uncontrolled removal, as noted by the American Society of Anesthesiologists 1
Catheter embolism occurs more often with long-term devices, and retained catheter fragments are usually asymptomatic and discovered incidentally on imaging, according to the American Society of Anesthesiologists 1
Management of catheter embolism requires urgent radiological or surgical retrieval, as recommended by the American Society of Anesthesiologists 1

Improper IV removal increases the risk of catheter-related bloodstream infections (CRBSI), as reported by the American College of Radiology 2
Common pathogens include coagulase-negative staphylococci, Candida species, Staphylococcus aureus, and Enterococcus, according to the American College of Radiology 2
Infection risk is higher with central lines versus peripheral lines, and proper exit site care after removal reduces infection risk, as noted by the European Society for Clinical Nutrition and Metabolism 3 and the American College of Radiology 2
Use of maximal sterile barrier precautions during insertion is essential to prevent infections, as recommended by 4

Abrupt removal of central venous catheters with associated thrombosis may disrupt thrombi and increase the risk of emboli, as reported by the American Society of Hematology 5
Guidelines recommend delayed removal of central venous catheters with associated thrombosis until after anticoagulation initiation, to reduce the risk of emboli leading to pulmonary embolism or paradoxical stroke, according to the American Society of Hematology 5

Generally, peripheral lines have a lower risk of serious complications compared to central lines, as noted by the European Society for Clinical Nutrition and Metabolism 3
Main risks associated with peripheral lines include local bleeding, phlebitis, and infiltration/extravasation injury, according to the American Society of Anesthesiologists 1
Central lines, particularly tunneled or implanted devices, require surgical cut-downs for proper removal and may leave behind fibrin sleeves or become attached to vessel walls, as reported by the American Society of Anesthesiologists 1
Choosing a catheter with the smallest caliber compatible with intended therapy is advised to minimize bleeding risk, as recommended by the European Society for Clinical Nutrition and Metabolism 3
Positioning the catheter tip at the superior vena cava-right atrium junction is recommended to reduce the risk of complications, according to [3] [6]

Improper removal of IVC filters by healthcare providers carries significant risks, as noted by the American College of Radiology 7 and the American College of Chest Physicians 8
Institutions should have systems to monitor patients with IVC filters and ensure proper reassessment for removal, according to the American College of Chest Physicians 8

Immediate assessment after IV removal should include evaluation for active bleeding, signs of air embolism, and inspection of the removed catheter, as recommended by the American Society of Anesthesiologists 1
Documentation of the condition of the catheter and any complications is essential, according to the American Society of Anesthesiologists 1
Monitoring for delayed complications, such as infection or thrombosis, is crucial, as noted by the American College of Radiology 2 and the American Society of Hematology 5
Secure fixation of catheters, patient education, and consideration of less visible or accessible placement sites can help prevent accidental dislodgement, according to the American Society of Anesthesiologists 1
Use of ultrasound guidance for vessel identification and cannulation is recommended to reduce complications, as noted by 3
More experienced operators should perform the procedure to reduce complications, as recommended by the American Society of Anesthesiologists 1
Choosing insertion sites that allow easy compression is recommended to facilitate bleeding management, according to the American Society of Anesthesiologists 1
Monitoring for hematoma formation, signs of hemothorax, and airway compromise with neck hematomas is essential after managing initial bleeding, as noted by the American Society of Anesthesiologists 1
