Ultrasonographic measurements of the inferior vena cava diameter in newborns: is it a useful tool for choosing an umbilical venous catheter?

Objectives: The primary outcomes of this study were to evaluate the diameters of the inferior vena cava (IVC) in a cohort of newborns and the correlation between newborn weight and IVC diameter. The secondary outcome was to evaluate the concordance between the measurements performed by the two investigators.

Methods: Two blind examiners performed an ultrasonographic (US) evaluation of the IVC diameter in neonates with a weight ranging from 2 to 4 kg.

Preterm Newborn Adaptive Responses to Daily Nursing during Neonatal Intensive Care Unit Stay, Associate with Neurodevelopment, 2 Years Later.

Objective: This study aimed to evaluate if adaptive responses of very preterm newborns to neonatal intensive care unit (NICU) daily nursing, specifically bathing and weighing procedures are associated with their neurodevelopment after 2 years.

Study Design: Twenty-six very preterm newborns, with a gestational age <32 weeks, were enrolled. Infants' adaptive responses to daily nursing were evaluated, at 30 to 32 to 35 postmenstrual age (PMA) weeks by an observational sheet.

The role of weighing-bathing sequence and postmenstrual age in eliciting adaptive/maladaptive responses in very low birth weight preterm infants.

Purpose: In the neonatal intensive care unit, preterm infants are exposed to several stressful stimuli. Inappropriate stimulation led to high risk for short- and long-term neurocognitive disabilities. This study aimed to evaluate whether the sequence of execution of weighing/bathing nursing procedures and postmenstrual age (PMA) have any effect on preterm infants' stress responses.
