ReviewMinimizing complications associated with percutaneous central venous catheter placement in children: recent advances.
To summarize existing knowledge regarding the prevalence of complications associated with temporary percutaneous central venous catheters placed in critically ill children, and to review evolving strategies to minimize the prevalence of these complications. ⋯ Complications during percutaneous central venous catheter placement in children are not rare and may be in part attributable to abnormalities in vascular anatomy. Thromboses in children with central venous catheters are increasingly recognized as an important problem for which evidence-based preventive measures are lacking. Catheter-associated bloodstream infection rates in critically ill children have markedly decreased over the last decade, associated with an increased emphasis on staff education and the use of insertion and maintenance bundles. Available evidence tends to support the use of two-dimensional ultrasound to augment the landmark technique for catheter placement, but more studies are needed.

ReviewMeasuring cystatin C to determine renal function in neonates.
The incidence of acute kidney injury in neonates is high and associated with up to a 50% mortality rate. The purpose of this review was to determine the feasibility of using serum cystatin C measurements to assist clinicians in making early and accurate diagnoses of acute kidney injury in neonates. ⋯ Cystatin C has all of the theoretical properties needed to be an ideal marker of renal function. It can be used to determine baseline renal function on day 1 and is increasingly being used to determine renal function in sick neonates. In the majority of studies, the day 1 cystatin C level ranged between 1 and 2 mg/L, which gradually declined in the first year of life. However, the number of available studies evaluating cystatin C in sick neonates is currently limited, and there are also no studies linking cystatin C levels in sick babies with short-term and long-term outcomes.
