Is it Necessary to Verify Blood Return in Monthly Port Flushes? Gloria B. Ascoli, RN, CRNI, Amy C. Brown, BSN, RN, Jessica L. Cooper, BSN, RN, Allison N. Crawford, BSN, RN, CRNI 3. To identify causes of central venous access device (CVAD) occlusion. 4. To state complications caused by CVAD occlusions A literature search was conducted to accomplish the research aims: Inclusion Criteria: Adult population, implanted port, malfunctioning port, recommendations for treatment Infusion Nurses Society (INS) archives and our internal policies (Sentara WaveNet) were also searched Sixteen articles met inclusion criteria Fifteen articles were selected for review Articles provided evidence supporting establishing blood return during monthly port flush Search of WaveNet revealed an established policy, providing an assessment tool and subsequent interventions in the setting of an occluded CVAD 2 3 4 Major complications include infection, infiltration, etc. (see chart 3) 2. To determine appropriate assessment criteria 1 Major causes of occlusion include mechanical, non-thrombotic, and thrombotic(see chart 2)

1. To determine the necessity of obtaining blood return during monthly implanted port flushes for patients with non-utilized ports Results Method Keywords: Monthly flush, blood return, fibrin sheath, implanted port, withdrawal occlusion We had four overall research aims: Assessment includes multiple pathways for determining causes of occlusion (see chart 1) Nurses in our outpatient infusion center see patients with implanted ports requiring routine monthly flushes for maintenance only Nurses were often encountering partial withdrawal occlusions from implanted ports during routine monthly port flushes Partial withdrawal occlusion the ability to flush easily but inability to aspirate blood Nurses questioned the necessity of a thrombolytic agent to establish blood return when no therapy was ordered Data Bases: Google Scholar, CINHAL, and PubMed Conclusions Research Aims It is necessary to establish blood return during a routine monthly port flush

Background Implications For Practice Blood return must be verified prior to any therapy via an implanted port, including monthly port flushes Thorough assessment of the patient and the CVAD for the potential cause of an occlusion will be performed, and the appropriate intervention will be performed to restore catheter patency (INS, 96) Nurses should be educated about the importance of the ability to aspirate blood from a CVAD prior to use Assessment of Central Line Catheter Occlusion Chart 1 Complete occlusion (unable to flush or aspirate blood) Complete (unable to flush or aspirate blood) Partial occlusion (negative blood aspiration) Partial (negative blood aspiration) Assess for external mechanical causes Assess for thrombotic causes Assess for non thrombotic causes Per protocol, instill catheter clearance agent Positive blood

return, proceed with catheter use Contact Interventional Radiology to assess Types of CVAD Occlusions Chart 2 Types of central venous catheter occlusion Mechanical External: Clamped or kinked IV tubing Tight suture at catheter exit site Non-coring needle dislodgement and misplacement Internal: Improper catheter tip placement Catheter kinking or compression Non-thrombotic Thrombotic Drug precipitates Crystallization of total parenteral nutrition admixtures Drug-to-drug incompatibilities Drug-to-solution incompatibilities Deposits of fibrin and blood components Intraluminal Fibrin Sheath Fibrin Tail Mural Thrombus Irritation from catheter rubbing against the intima of the vessel wall Portal Reservoir Occlusion 42% non thrombotic 58% Thrombotic

Complications Associated with Central Line Occlusions Chart 3 Central line occlusions compromise patient care Risk for Infection Formation of fibrin deposits and biofilm is a natural response that can start upon catheter placement Attracts, encloses, and protects bacteria and other microorganisms Microorganisms can be released into the bloodstream causing central line associated infection Infiltration or Extravasation Infiltration causes pain, discoloration, and swelling Extravasation is more severe, and can result in pain, edema, and tissue necrosis Thrombosis A thrombus between the catheter and the cell wall can lead to complete blockage of the vein This can be a life-threatening condition with potential complications, such as pulmonary embolism Delay in treatment Canceled or delayed procedures Increased length of stay (LOS) Interruption in administration of medications and solutions, especially vesicants References Andris, D., Elizabeth, K., Schulte, W., Ausman, R., & Quebbeman, E.
