Comparative Study Observational Study
The intracavitary electrocardiography method for positioning the tip of epicutaneous cava catheter in neonates: Pilot study.
The neonatologists of Sant'Anna and San Sebastiano Hospital of Caserta have carried out a pilot study investigating the safety, feasibility, and accuracy of intracavitary electrocardiography for neonatal epicutaneous cava catheter tip positioning. ⋯ We conclude that the intracavitary electrocardiography method is safe and accurate in neonates as demonstrated in pediatric and adult patients. The applicability of the method is 97% and its feasibility is 79%. The overall accuracy is 76% but it rises to 97% if "peak" P wave is detected.

Comparative Study
Comparison of two types of catheters through femoral vein catheterization in patients with lung cancer undergoing chemotherapy: A retrospective study.
This study aimed to investigate the effects and complications of different types of peripherally inserted central catheters through femoral vein catheterization in patients with lung cancer undergoing chemotherapy. ⋯ Single-lumen power-injectable peripherally inserted central catheters with no valve had a high gravity flow rate, were strong and not prone to rupture, tolerant to high-pressure injection, and were more suitable for femorally inserted central venous catheterization in patients with lung cancer undergoing chemotherapy.

Observational Study
Electrocardiography-controlled central venous catheter tip positioning in patients with atrial fibrillation.
A significant increase of the p-wave of a real-time intracavitary electrocardiography is a reliable and safe method to confirm the central venous catheter tip position close to the atrium. However, conflicting data about the feasibility of electrocardiography exist in patients with atrial fibrillation. ⋯ Electrocardiography-guided central venous catheter tip positioning is a feasible real-time method for patients with atrial fibrillation. Combined with ultrasound, the electrocardiography-controlled central venous catheter placement may eliminate the need for postinterventional radiation exposure.

Comparative Study
Effect of catheter diameter on left innominate vein in breast cancer patients after totally implantable venous access port placement.
To evaluate the effect of catheter diameter on left innominate vein stenosis in breast cancer patients after placement of totally implantable venous access ports. ⋯ The incidence of left innominate vein stenosis was higher after implantation of totally implantable venous access ports with 8F catheter rather than with 6.5F catheter. Considering that using 8F catheter versus 6.5F catheter has no advantage in terms of performance of the device, the results of our study suggest that ports with catheters >7F should be avoided.

Hemodialysis is the main modality of renal replacement therapy in Singapore. However, a majority of the patients in Singapore are initiated on hemodialysis via a catheter. This study examines the complication rates and factors predicting catheter-related bloodstream infections and mortality rates in patients who were initiated on hemodialysis at our institution. ⋯ In conclusion, prolonged duration of catheter insertion is found to be a risk factor for catheter-related bloodstream infection in hemodialysis patients, and its development is associated with increased mortality. Early referral to a nephrologist and creation of arteriovenous fistula in pre-end-stage renal disease patients are pivotal in improving the outcomes of patients.
