# The effects of temperament type on infusion extravasation in newborns

## TL;DR

Newborns with certain temperaments are more likely to experience infusion extravasation, a complication during IV therapy.

## Contribution

This study identifies temperament types as a novel risk factor for infusion extravasation in newborns.

## Key findings

- Newborns with intermediate temperament type had a higher risk of infusion extravasation.
- Low body weight and specific medical conditions increased the likelihood of extravasation.
- Temperament types like consolability and peak of excitement were independent risk factors.

## Abstract

Infusion extravasation has an increased incidence in newborns, which can result in various adverse outcomes. This study aimed to investigate the effects of different types of temperament on infusion extravasation in newborns. A total of 209 newborns aged 4–7 days who were treated with infusion therapy were assessed for temperament type using the neonatal behavioral assessment scale score (NBAS). The 2009 Infusion Nurses Society clinical grading criteria for extravasation were used, and the clinical data of the newborns, such as gestational age and body weight, were collected. Out of 209 newborns assessed, 107 developed infusion extravasations, with an incidence rate of 51.2%. Newborns with intermediate temperament type were more prone to develop infusion extravasation. Newborns with low body weight, amniotic fluid aspiration syndrome, or meconium aspiration syndrome were prone to develop infusion extravasation. Body weight, temperament type of consolability, temperament type of peak of excitement, diseases, general temperament type, and NBAS total scores of the neonates were independent risk factors for infusion extravasation. Thus, different types of temperament can have an impact on neonatal extravasation.
