Unlocking Common ED Procedures: Approach to the Patient with Difficult Vascular Access
Obtaining peripheral intravascular (IV) access is a common procedure in the Emergency Department and an essential aspect of managing critically ill patients... up to 30% of which are in patients with difficult vascular access (DVA). Factors associated with DVA include obesity, diabetes, and IV drug use, among others. While some of these patients may ultimately require central venous catheter placement, any astute emergency physician should have a few tricks up his or her sleeve to obtain initial vascular access and avoid the time and associated risks of this invasive procedure.

Approach to the Patient with Difficult Vascular Access
Obtaining peripheral intravascular (IV) access is a common procedure in the Emergency Department and an essential aspect of managing critically ill patients.
New Kid on the Block: The “Easy IJ”
The “Easy IJ” involves placing an extra-long 18-gauge single-lumen catheter (those typically used for US-guided IVs) in the internal jugular vein. In one study in the emergency setting among patients who had failed traditional ultrasound-guided PIV placement, this technique was successful 88% of the time.
Unlocking Common ED Procedures: Micropuncture Kits for Difficult Vascular Access
The micropuncture needle’s echogenic nature improves visualization with ultrasonography, providing the most benefit for patients with small vascular structures or aberrant anatomy. In short, the use of echogenic micropuncture needles is a vital skill for the emergency physician, and can be beneficial when placing peripheral IV or arterial catheters in challenging cases, although little literature has been published in this area.
Approach to Difficult Vascular Access
Deep veins of the upper arm are generally larger and are the best targets, especially the basilic and cephalic veins.
Difficult venous access in the emergency department
Placement of peripheral venous devices (PIV) could be challenging, especially in difficult venous access (DIVA) patients. Ultrasound guided long peripheral intravenous devices (US-LPIV) have been proposed as an alternative. The aim of our study is to compare performance of PIVs vs US-LPIVs in DIVA patients admitted to the emergency department.
Hemodynamic access for the crashing patient: The dirty double
Currently I begin by placing two catheters in the femoral artery and vein, immediately next to each other. This may be done using a single sterile field. The central venous catheter is placed first because it is generally more important. In highly acute situations, a nurse may attach extension tubing to the central line and start using it immediately (prior to inserting the arterial catheter). This will compromise the sterility of a portion of the sterile field, which can then be covered with a sterile towel. These lines are placed with the intention that they will be “dirty” lines which must be removed within ~24 hours. They are placed using sterile gloves, a mask, and a sterile sheet but without full sterility.
Peripherally inserted central catheter
Peripherally inserted central catheters (PICCs), often incorrectly tautologically termed PICC lines, are a type of central venous catheter predominantly used amongst oncology patients and those with chronic diseases (e.g. cystic fibrosis). Basilic and brachial veins are most commonly used; preprocedure ultrasound can be performed to identify an appropriately-sized vessel and ensure it is clot-free.
Seldinger Technique for Placement of “Peripheral” Internal Jugular Line: Novel Approach for Emergent Vascular Access
Since its introduction in 1953, the Seldinger technique has been used with great success to cannulate a multitude of blood vessels, hollow viscous structures, and potential anatomical spaces.
The Vanishing Target Sign: Confirmation of Intraluminal Needle Position for Ultrasound Guided Vascular Access
In our experience, consistent success with USGPIV placement in patients with difficult access using a dynamic one-person technique is a challenging procedure. In an attempt to help teach this effectively, we have developed a method that employs a sign we call the “vanishing target” to ensure intraluminal positioning of the catheter needle tip.
Ultrasound: Skills of Ultrasound-guided Vascular Access
Vascular access is a common procedure in the emergency department. Using ultrasound to visualise vessels is helpful, but the additional skill of using ultrasound to guide the procedure is even more so. Central, femoral and basilic vein cannulations are described, together with key aspects of imaging technique.
Vascular Access in Pediatric Patients in the Emergency Department: Types of Access, Indications, and Complications
It is a mainstay of any ED practice, and often a life-saving procedure: vascular access. But it is challenging to obtain and maintain in pediatric patients, especially in life-threatening cases when every second is critical.
Unlocking Common ED Procedures: Approach to the Patient with Difficult Vascular Access
Consider the external jugular vein before jumping to ultrasound-guided PIV. Once landmark-based attempts have been unsuccessful, before reaching for an ultrasound, consider the oft-neglected external jugular vein. Place the patient in Trendelenburg position and have them rotate their head away from the target vessel. While standing at the head of the bed, use your left thumb to provide traction and your index finger to compress the vein proximally. Cannulate midway between the angle of the jaw and the clavicle. Having the patient perform a Valsalva maneuver can also further distend the vessel. If ultrasound-guided peripheral IV placement isn’t successful, consider an “easy-IJ” before placing a CVC. Midline catheter placement is an emerging alternative to both ultrasound-guided IVs and CVCs.
SAEM
Vascular Access is the cornerstone of emergency medicine and part of every emergency medicine physician’s safety net. With that said, not every patient that enters the ER will require vascular access. It is important to know when to obtain access and what type of access should be used. Furthermore, an emergency medicine physician must be comfortable placing all forms of access.
Association for Vascular Access
The Association for Vascular Access (AVA) is an organization of healthcare professionals founded in 1985 to support and promote the specialty of vascular access. The mission of AVA is to distinguish the vascular access specialty and define standards of vascular access through an evidence-based approach designed to enhance healthcare.
