Infants at neonatal intensive care units (NICU) are invariably exposed to various procedural and environmental stimuli. The study was performed to compare the pain responses in three NICU stimulants and to examine the clinical feasibility for NICU infants using CRIES, FLACC and PIPP.
In a correlational study, a total of 94 NICU stimulants including angio-catheter insertions, trunk-rubbings and loud noises, was observed for pain responses among 64 infants using CRIES, FLACC and PIPP.
A significant difference was identified among the mean scores in CRIES(F(2, 91)=47.847, p=.000), FLACC(F(2, 91)=41.249, p=.000) and PIPP(F(2, 91)=16.272, p=.000) to three stimulants. In a Post-hoc Scheff test, an angio-catheter insertion showed the highest scores in CRIES, FLACC and PIPP compared to the other two stimulations. A strong correlation was identified between CRIES and FLACC in all three stimulations(.817 < r < .945) while inconsistent findings were identified between PIPP and CRIES or FLACC.
The results of the study support that CRIES and FLACC are reliable and clinically suitable pain measurements for NICU infants. Further studies are needed in data collection time-point as well as clinical feasibility on PIPP administration to assess pain response in infants, including premature infants.
This was a cross sectional descriptive study to introduce the Infants Coma Scale (ICS), describe mental status of high risk infants using ICS and explore the relationships between ICS and clinical variables in infants hospitalized in a neonatal intensive care unit of a university hospital in Korea.
After ICS was developed and tested by the authors, a research nurse evaluated the mental status of the infants using the English version of ICS and obtained clinical information on the infants from their medical records.
Data from 88 infants were analyzed. About 60% were male, 90% were preterm births, and 40% had pathologic abnormalities. Their mean gestational age was 32.4 (±3.50) weeks and the mean birth weight was 1,842 (±728.6) grams. The Cronbach's alpha for the ICS was .78. There was a statistically significant positive correlation between ICS total score and five clinical variables including gestational age, birth weight, 1 and 5 min Apgar scores and respiration status.
Mental status is an important parameter in nursing assessment. ICS is a valid and reliable instrument, which clinicians can easily use to evaluate the mental status of high risk infants.
