Point of Care Ultrasound to Evaluate Peripheral Intravenous Catheters

Abstract

Background: Several studies have described the use of ultrasound for the placement of peripheral intravenous catheters (PIV); however, visual and tactile inspection remains the primary clinical tool for the identification of infiltration. An improperly positioned PIV is an avoidable cause of significant morbidity and mortality to a patient. Case: We describe a technique using point of care ultrasound for the assessment of two PIV to confirm functionality in a 68-year-old male scheduled for an above the knee amputation. This technique can be used for both superficial and deep peripheral veins where the detection of catheter infiltration by physical exam alone is often challenging. Conclusion: The ubiquitous use of ultrasonography has revolutionized the field of medicine. Point of care ultrasound for the evaluation of questionable peripheral catheters can help prevent harm to a patient, especially during transitions of care.
