Patients admitted to cardiac intensive care unit need administration of drugs intravenously often in concomitance of therapeutic techniques such as non-invasive ventilation, continuous renal replacement therapy and intra-aortic balloon counterpulsation. Therefore, the insertion of central venous catheters provides a reliable access for delivering medications, laboratory testing and hemodynamic monitoring, but it is associated with the risk of important complications. In our study, we tested the efficacy and safety of peripherally inserted central catheters to manage cardiac intensive care. ⋯ In patients admitted to cardiac intensive care unit, peripherally inserted central catheters' insertion was feasible in a high percentage of patients and was associated with low infective complications and clinical thrombosis rate.

Comparative Study Observational Study
Ultrasound-guided intravenous access in adults using SonoStik®, a novel encapsulated sterile guidewire: A prospective cohort trial.
We evaluated the performance of an encapsulated guidewire designed for single-handed use with ultrasound-guided vascular access (SonoStik) with Seldinger technique, as compared with conventional intravenous catheters placed under ultrasound guidance in healthy subjects. ⋯ This study demonstrated that emergency department technicians skilled in ultrasound-guided intravenous access could successfully place SonoStik 83.3% of the time in vessels that were unable to be palpated or visualized. Compared to standard ultrasound intravenous cannulation, the odds ratio of successful cannulation with SonoStik was 0.91 (95% confidence interval = 0.04-17.5). In all cases, the time required to successfully insert SonoStik was less than 4 min from tourniquet application to catheter advancement to hub, with a mean time of less than 2.5 min.

Medium-term intravenous access in children is normally achieved by means of repeated multiple peripheral intravenous cannula insertions or peripherally inserted central catheters. Long peripheral cannulas might offer an alternative to these devices in children. Our aim was to clarify whether long peripheral cannulas provide reliable medium-term intravenous access avoiding the need for multiple peripheral intravenous cannulations or peripherally inserted central catheter insertion in children undergoing surgery. ⋯ Long peripheral cannulas represent a valid option for medium-term intravenous access in children undergoing surgery. Majority of patients will be successfully treated with one long peripheral cannula for the duration of their treatment without the need for further cannulation.
