PICC insertion and veins of the arm size variation during dialysis treatment: A prospective observational study.

Background: Peripherally Inserted Central Catheters play an increasingly important role in Central Venous Access Devices. However, the use of these devices should be carefully considered in specific situations such as central catheterisation in patients with chronic kidney disease. When evaluating the feasibility of placement for a patient undergoing dialysis, the relationship between changes in circulating volume before and after dialysis treatment, and potential variations in the size of deep veins in the upper limbs, should be considered.

Midline catheters for blood gas and acid/base monitoring in critical patients: A prospective observational study.

Background: Arterial lines and central venous catheter (CVC) allow to monitor patients' acid-base status and gas exchange. Their placement and maintenance may however be burdened by severe complications. Midline Catheters (MC) are peripheral venous accesses that are less invasive and easier to insert compared to CVC and arterial lines.

Femorally inserted central catheters with exit site at mid-thigh: A low risk alternative for central venous catheterization.

Background: Femorally inserted central catheters are increasingly used, especially after the COVID-19 pandemic, also thanks to widespread of tunneling techniques that allow the exit site to be moved away from the groin.

Methods: In this retrospective observational study, femorally inserted catheters, with exit site at mid-thigh and the tip in Inferior vena cava or in Inferior vena cava at the junction with right atrium, have been observed and complications have been analyzed. All catheters were inserted by trained Nurses of a tertiary hospital Vascular Access Team.

Management of vascular access for extracorporeal life support: A cohort study.

Extracorporeal membrane oxygenation (ECMO) is required for patients with refractory cardiac or respiratory failure. Inadequate securement of ECMO cannulae may lead to adverse events, ranging from line kinking to catastrophic accidents, such as air entrainment into the circuit or massive bleeding. Furthermore, the micro-motion of the cannulae at the entry site might increase the risk of local infections.

Reliability of cutaneous landmarks for the catheter length assessment during peripherally inserted central catheter insertion: A retrospective observational study.

Introduction: Peripherally inserted central catheters are very common devices for short, medium and long-term therapies. Their performance is strictly dependent on the correct tip location, at the junction between the upper caval vein and the right atrium. It is very important to obtain an estimated measure of the catheter, in order to reach the cavo-atrial junction and optimize the catheter length.

Ultrasound-guided tip location of midline catheters.

Introduction: Midline catheters are widely used in clinical practice. Proper placement of midline catheter tip is usually assessed only by aspirating blood and flushing with normal saline without resistance.

Purpose: To describe the ultrasound-guided tip location for midline catheters and its feasibility and to compare incidence of catheter-related venous thrombosis associated with or without ultrasound tip localization.

Seafloor doming driven by degassing processes unveils sprouting volcanism in coastal areas.

We report evidences of active seabed doming and gas discharge few kilometers offshore from the Naples harbor (Italy). Pockmarks, mounds, and craters characterize the seabed. These morphologies represent the top of shallow crustal structures including pagodas, faults and folds affecting the present-day seabed.
