BACKGROUND This is the first reported study of histologically confirmed migration from intravenous access devices in children. METHODS The capsules from around intravenous access devices were examined by light microscopy to determine the extent of the foreign body response; energy dispersive x ray analysis was performed to document the elemental content of the foreign material. RESULTS A fi...

Patent ductus arteriosus (PDA) is common congenital heart disease which may require treatment as transcatheter percutaneous device closure (PDA device closure) or surgical ligation in symptomatic full-term patients. Surgical ligation is an invasive procedure and has more complications especially in the neonates. Problems in PDA device closure are difficult vascular access, manipulation of cathe...

This paper proposes an uplink non-orthogonal multiple access (NOMA) system with device-to-device (D2D) communication, enabling NOMA users to communicate other users/devices using D2D communication improve the capacity. In NOMA-D2D system, two cellular communicated BS NOMA, and simultaneously downlink NOMA. Closed-form solutions for ergodic sum capacity of proposed are derived analytically. The ...

The availability of ultrasound (US) devices has refined techniques for vascular access. The resident trainee’s ability to learn US techniques depends upon device availability, skills, and motivation of instructors. We hypothesized that hands-on teaching program of US techniques for vascular access would have a positive impact on the trainee’s perceptions. After IRB approval, PGY3 anesthesiology...
