![]() Within low- and middle-income countries, the main complication is mortality and studies have shown that hypothermia increases a neonate's risk of mortality by up to 23 times ( 8). Hypothermia during the neonatal period leads to significant short- and long-term complications. Risk factors include prematurity (birth prior to 37 weeks completed gestation) ( 3), low birth weight (birth weight <2500 g) ( 4, 5), low maternal socioeconomic status, younger maternal age ( 6) and birth outside of the hospital ( 7). It is defined by the World Health Organization as an axillary temperature below 36.5☌ ( 1) and is estimated to affect 11–92% of neonates ( 2). Neonatal hypothermia is a global problem that causes significant morbidity and mortality particularly in low- and middle-income countries. However, the accuracies of different devices are hard to determine due to variable methodologies used in relevant studies and hence, further research that addresses these gaps is needed. This paper discusses the current evidence available regarding the utility of these devices, and identifies barriers to valid comparison of different thermometry methods.Ĭonclusion: Many methods for temperature monitoring in neonates are currently available, each with their own advantages and disadvantages. Newer innovations that are also available include liquid crystal thermometers and the BEMPU TempWatch. ![]() The main methods available for temperature monitoring in neonates are human touch and mercury-in-glass, electronic, infrared tympanic and other infrared thermometers. Results: A total of 160 papers were retrieved for narrative synthesis. Methods: A recent search and narrative synthesis of relevant studies published between Januand on the OVID Medline, PubMed and Google Scholar databases. Objectives: The aim of this review was to identify and compare current methods available for temperature monitoring of neonates beyond the delivery room, including the accuracy, advantages and disadvantages of each. Many studies have compared different thermometers in neonates, however, there is a lack of consensus regarding which of the currently available thermometers is most suitable for use in neonates. Introduction: Accurate temperature monitoring of neonates is vital due to the significant morbidities and mortality associated with neonatal hypothermia. 3The Ritchie Centre, Hudson Institute of Medical Research, Melbourne, VIC, Australia.2Monash Newborn, Monash Children's Hospital, Monash Health, Clayton, VIC, Australia.1Department of Paediatrics, Monash University, Clayton, VIC, Australia.The linear relationship between the three sites studied was not found to be affected by age, gender, number of temperature samples taken, post/non-operative admission or peripheral temperature.Donna Lei 1 Kenneth Tan 1,2,3 Atul Malhotra 1,2,3 * Very high statistical correlations were obtained which demonstrate the strength of the relationships between the three sites (rectal-axillary temperature difference R = 0.97 PA blood-rectal temperature difference R = 0.99 PA blood-axilla temperature difference R = 0.97). Of the 16 patients who had their PA blood temperature monitored mean rectal temperature was 0.1 degree C above PA blood temperature and mean axillary temperature was 0.19 degree C below PA blood temperature. The mean difference between rectal and axillary temperature for all 31 patients was 0.32 degree C. Simultaneous recordings of PA blood temperature, rectal temperature and axillary temperature were taken every 4h for up to 7 days. 31 adults had their temperatures monitored. This research study was undertaken to determine the relationship between pulmonary artery (PA) blood temperature, rectal temperature and axillary temperature for adult patients admitted to an intensive care unit (ICU).
