Experiences and perceptions of critical care nurses on the use of point-of-care ultrasound (POCUS) to establish peripheral venous access in patients with difficult intravenous access: a qualitative study.

Ultrasound-guided peripheral intravenous access can become a valuable skill for CCN's caring for patients with DIVA in the intensive care unit. This practice can potentially reduce patient suffering, improve patient outcomes, enable the CCN to provide high-quality care, improve action readiness, time management and job satisfaction for the nurses.
