Complications of vascular access devices

Area of Science:

• Emergency Medicine
• Vascular Access Devices
• Medical Technology

Background:

• The aging population and advancements in medical treatments lead to a rise in patients with vascular access devices (VADs).
• Emergency departments (EDs) are seeing more patients presenting with both external and internal VADs.
• These devices, while beneficial, can also lead to complications and require specific management considerations.

Purpose of the Study:

• To outline best practices for emergency physicians managing patients with vascular access devices.
• To highlight potential complications associated with VADs in the emergency setting.
• To emphasize the importance of device awareness for diagnostic procedures and patient safety.

Main Methods:

• Review of current literature and clinical guidelines regarding vascular access devices in emergency medicine.
• Discussion of aseptic techniques, anticoagulation, and management of device-related issues.
• Consideration of implications for diagnostic imaging and patient safety protocols.

Main Results:

• Safe and rapid vascular access can be achieved with proper aseptic technique and heparinization.
• Potential catheter and pump complications should be included in the differential diagnosis for patients with functioning VADs.
• Patients with metallic implantable devices must avoid electromagnetic radiation unless nonmetallic alternatives are used.
• Documentation of VAD presence is essential to prevent misinterpretation of imaging studies.

Conclusions:

• Emergency physicians must be proficient in managing patients with vascular access devices.
• Vigilance for device-related complications and adherence to safety protocols are paramount.
• Understanding device limitations, particularly concerning imaging, is critical for comprehensive patient care.
