Variations in incubator temperature and humidity management: a survey of current practice

Abstract Aim: To describe and assess routine procedures and practices for incubator temperature and humidity management in France in 2009. Methods: A questionnaire was sent to all the 186 neonatal care units in France. Results: The questionnaire return rate was 86%. Seventy‐five per cent of the units preferred skin servo‐control to air temperature control in routine practice. Air temperature control was mainly used for infants with a gestational age of more than 28 weeks and aged over 7 days of life. In general, thermal management decisions did not depend on the infant’s age but were based on a protocol applied specifically by each unit. All units humidified the incubator air, but there was a large difference between the lowest and highest reported humidity values (45% and 100% assumed to be a maximal value, respectively). More than 65% of the units used a fixed humidity value, rather than a variable, protocol‐derived value. Conclusion: We observed large variations in incubator temperature and humidity management approaches from one neonatal care unit to another. There is a need for more evidence to better inform practice. A task force should be formed to guide clinical practice.
