The Bayley Scales of Infant and Toddler Development—Third Edition (Bayley-III) is a gold standard series of behavioural assessments used by clinicians and researchers to assess the developmental functioning of young children. The rigorous psychometric properties of the tool are attributed to the carefully standardised normative sample and quantitative scoring system. It is a common end-point assessment used in neonatal trials and is routinely used in a clinical setting to assess the development of children at risk of delay. Incidence of developmental delay is higher in clinical populations such as those born preterm or with complications such as neonatal encephalopathy. Early identification of delay is critical as early intervention is most effective in minimising impairment; therefore, routine assessment of developmental outcomes is recommended, particularly among high-risk populations.

Blood cTnT, NTpBNP and a PDA scoring system at 48 h may facilitate the identification of those infants with a PDA, who are at greatest risk of poor neurodevelopmental outcome at 2 years of age.

This study demonstrates that Quiet periods are feasible for infants undergoing neonatal intensive care. The NICU environment was altered significantly for light, noise, infant handling and staff activity for a specified time period. These changes were associated with a reduced median diastolic blood pressure and mean arterial pressure and a decrease in infant movements.

Aims/background-In a prospective study the degree of distress caused by retinopathy of prematurity (ROP) screening in a cohort of preterm infants was assessed and the modifying eVects of nesting in reducing their discomfort was evaluated. Methods-38 preterm infants were included in the study. 19 infants were placed in a nest with boundaries (intervention group) and 19 infants were placed on a cot blanket (control group). Observations were made 2 minutes before, throughout, and 2 minutes after ROP examination. The factors observed were crying responses, neurobehavioural activity, and physiological changes (heart rate, oxygen saturation). Recordings were made using a video camera for crying and neurobehavioural activity and an Oxypleth monitor for heart rate and oxygen saturation. Results-During ROP screening, the total group of 38 infants (nested and nonnested combined) displayed increased neurobehavioural activity (p<0.01) and crying (p<0.01). The increased activity and crying coincided with the invasive part of the procedure. The distress caused by ROP screening was significantly less for the nested group compared with the non-nested group for both movement activity (p<0.01) and crying (p<0.01). The physiological data, heart rate, and oxygen saturation were not statistically significant. Conclusion-ROP screening is distressing for preterm infants. Nesting can significantly reduce this discomfort. The findings in this study are of value in designing more optimal ROP examination schedules for infants.
