Objective. Determine the level of environmental and periauricular noise in preterm babies and identify the sources generating noise in the Neonatal Intensive Care Unit -NICU- of a reference hospital in San Luis Potosí, Mexico. Methods. Cross-sectional and analytic study of the measurement of the level of environmental noise in five critical areas of the NICU, according with the method of measurement of noise from fixed sources by the Mexican Official Norm and periauricular at 20 cm from the preterm patient’s pinna. The measurements were carried out during three representative days of a week,morning, evening and nocturnal shifts. A STEREN 400 sound level meter was used with 30 to 130 dB range of measurement and a rate of 0.5 s. Results. The average level of periauricular noise (64.5±1.91dB) was higher than the environmental noise (63.3±1.74 dB) during the days and shifts evaluated. The principal noise sources were activities carried out by the staff, like the nursing change of shift and conversations by the staff, which raised the level continuously or intermittently, operation of vital support equipment (alarms) and incidences (clashing of baby bottles and moving furnishings) producedsudden rises of noise. Conclusions. Environmental and periauricular noise in NICU exceeds by two and almost three times the 45 dB during the day and 35 dB at night from the norm in hospitals. It is necessary to implement permanent noise reduction programs to prevent sequelae in the preterm infant and professional burnout in the nursing staff.

The aim of this study was to identify needs of families with premature newborns in the Neonatal Intensive Care Unit, perceived by parents and nurses. The study was conducted in the Kaunas Perinatal Center, Neonatal Intensive Care Unit, Hospital of Kaunas University of Medicine. The sample consisted of 181 parents and 37 nurses. The NICU Family Needs Inventory was used for data collection. The instrument included five dimensions of needs. Reliability of the scale was identified as 0.94 using Cronbach’s a. Results. The importance of the needs by parents was prioritized as following: assurance, proximity, information, support, and comfort, and by nurses – assurance, information, proximity, support, and comfort. The needs for assurance, proximity, and information were significantly more important for parents as compared with nurses. Needs for support were significantly more important for nurses. Forty-seven (83.9%) items (out of 56) were identified as important by parents and 49 (87.5%) items – by nurses. Both parents and nurses identified the same 7 items within the group of 10 most important. Parents and nurses identified the same 7 items within the group of 10 least important. Conclusions. Both groups of respondents identified needs for assurance as the most important for parents. The needs for comfort were perceived as the least important by parents and nurses. All groups of needs, except the needs for support, were significantly more important for parents as compared with nurses. Both parents and nurses identified the same 44 items (out of 56) as important for parents in the Neonatal Intensive Care Unit. The 10 most important need statements and 10 least important need statements were identified by parents and nurses.
