Rapid Assessment of Vascular Exit Site and Tunneling Options (RAVESTO): A new decision tool in the management of the complex vascular access patients.

In the last decade, different standardized protocols have been developed for a systematic ultrasound venous assessment before central venous catheterization: RaCeVA (Rapid Central Vein Assessment), RaPeVA (Rapid Peripheral Vein Assessment), and RaFeVA (Rapid Femoral Vein Assessment). Such protocols were designed to locate the ideal puncture site to minimize insertion-related complications. Recently, subcutaneous tunneling of non-cuffed central venous access devices at bedside has also grown in acceptance. The main rationale for tunneling is to relocate the exit site based on patient factors and concerns for dislodgement. The tool we describe (RAVESTO-Rapid Assessment of Vascular Exit Site and Tunneling Options) defines the different options of subcutaneous tunneling and their indications in different clinical situations in patients with complex vascular access.

Alternative exit sites for central venous access: Back tunneling to the scapular region and distal tunneling to the patellar region.

Uncooperative elderly patients with cognitive disorder are often confused and/or agitated. Risk of involuntary venous access device dislodgment is high in these patients. This is equally likely with peripherally inserted central catheters and centrally inserted central catheters but less common with femorally inserted central catheters. Solutions to this problem include strict continuous patient observation, using sutures or subcutaneous anchored securement, wrapping the arm to "hide" the line, or using soft mittens to occupy the hands. However, some patients are able to disrupt the dressing, dislodge the catheter, and often pull the catheter out completely. In some cases, the patient may also overcome the resistance offered by the stitches or by the subcutaneous anchored securement device. In a recent paper on the impact of subcutaneously anchored securement in preventing dislodgment, the only demonstrated failures occurred in non-compliant elderly patients. Creation of an alternative exit site is an emerging trend in patients with cognitive impairment at high risk for catheter dislodgement. Subcutaneous tunneling from traditional insertion sites such as the jugular, axillary, or femoral veins allows placement of the exit site in a region inaccessible to the patient. The following two case reports demonstrate the technique for tunneling a femorally inserted central catheter downward to the patellar region and for tunneling a centrally inserted central catheter to the scapular region. Internal review board approval was not deemed necessary as subcutaneous tunneling is not a new technique. In our experience, such maneuvers can be successfully performed at the bedside.

Venous catheter at alternate exit site in a 2-year-old requiring long-term antibiotics for osteomyelitis: A case report.

In the pediatric population, vascular access is often challenging to secure and to maintain, especially for long-term intravenous (IV) treatment. The traditional approach for patients who require long-term IV antibiotics is placement of a peripherally inserted central catheter (PICC). The challenge in the pediatric population is the high risk of dislodgement after PICC placement, as these patients tend to pull their line out accidentally or purposefully. Current bedside options to prevent catheter dislodgement include adhesive securement devices, subcutaneous securement devices, sutures, and wrapping the site in gauze. However, these modalities often fail, leading to delay in administration of IV therapies, including life-saving antibiotics.A novel approach to this very common and serious issue is to tunnel the catheter subcutaneously, thereby placing the exit site in a location difficult for the patient to reach. Tunneled catheters generally are placed in children for long-term vascular access and insertion has primarily been reserved for surgeons in the operating room or by interventional radiologists. The following case report describes a central venous access catheter placed in the internal jugular vein and tunneled to the medial dorsal thoracic region successfully at the bedside, using intracavitary electrocardiogram (ECG) navigation under moderate sedation. Although a novel exit site, the technique of tunneling and use of the jugular vein is no different than traditional tunneling techniques therefore it was not deemed necessary to seek internal review board approval.

Report of Modification for Peripherally Inserted Central Catheter Placement: Subcutaneous Needle Tunnel for High Upper Arm Placement.

The majority of peripherally inserted central catheters (PICCs) are currently inserted with the aid of ultrasound guidance in the middle third of the upper arm. A growing patient population is presenting with challenging vessel access requiring placement of the PICC in the high upper third of the arm. To avoid this suboptimal exit site, a subcutaneous tunneling of the PICC is established away from the axilla to a more appropriate skin exit site. A prospective evaluation was performed in a single facility for all PICC placements from September 2014 to June 2015. Of the results of 685 PICC requests received during the study, 50 (7.2%) were placed with the modified Seldinger tunneling technique with 96% success. There were no reports of increased pain, insertion complications, or therapy failures. Subcutaneous tunneling, when applied to bedside PICC insertions, provides a safe, effective, and cost-efficient option for a select, more challenging patient population.
