|38.||When removing a CVAD the patient MUST be placed in bed in a supine position (1). Prior to repositioning the patient following removal of a CVAD , ensure the dressing is airtight and occlusive.||Consensus|
|39.||Removal of a CVAD should be timed to occur at end inspiration or during expiration for patients who are not on a ventilator.||Consensus|
|40.||Following CVAD removal pressure must be applied with sterile gauze until haemostasis is achieved. The insertion site must be sealed immediately using an airtight occlusive dressing. This dressing is to remain intact and insitu for 48 hours to reduce the risk of late air embolism.||Consensus|
|41.||Routine collection of the CVAD tip is not required when removing the device. If a catheter-related bloodstream infection is suspected the medical team may request that the tip is sent for microbiological examination and a blood culture collected from a peripheral vein within 4 hours of CVAD removal (2).||Consensus|
Removal of the CVAD must be documented in the clinical record.
|43.||Following removal of a CVAD the condition of the site must be monitored at 24 and 48 hours at a minimum. This must be documented in the clinical record.||Consensus|
Safety alert 3: Air embolism
Many of the recommendations relating to removal have been made in the context of risk minimisation for air embolus. Data from the Incident Information Management System in NSW indicates that a number of patients are subject to this complication every year and in some cases this has been related to the removal technique. The practice review yielded numerous techniques for ensuring patients (without positive pressure ventilation) do not inhale during the procedure. See also the CEC Clinical Focus Reports.
Practice point 6 - Check CVAD when removed
When removing a CVAD, which may have been trimmed on insertion (i.e. PICC), the entire length removed must be visualised and checked against the original documentation to ensure that the entire catheter has been removed. This should be recorded in the patient’s medical record.
Grading of recommendations
|Grade of recommendation||Description|
|A||Body of evidence can be trusted to guide evidence|
|B||Body of evidence can be trusted to guide practice in most situations|
|C||Body of evidence provides some support for recommendation/s but care should be taken in its application|
|D||Body of evidence is weak and recommendation must be applied with caution|
|Consensus||Consensus was set as a median of ≥ 7|
