Zusammenfassung:Background and aimsTemperature control during therapeutic hypothermia in newborns with hypoxic ischaemic encephalopathy needs to be monitored with great care since this treatment can cause serious side effects. The temperature measured in the pulmonary artery is considered the ‘gold standard’; however, this is not suited to patients in the NICU. A reliable and less invasive method is the temperature measured in the oesophagus.AimWe hypothesised temperature measurements during hypothermia using an oesophageal probe reflects higher temperatures than measurements using a rectal probe.Methods20 newborns treated with hypothermia were provided with a continuous rectal temperature probe as well as an oesophageal temperature probe. Both measurements were registered over a period of 72 h of hypothermic therapy.ResultsLinear multilevel regression analysis revealed significant associations between rectal and oesophageal temperatures. We recorded a mean difference per degree between rectal and oesophageal temperatures of 0.12°C. This difference is 0.17°C higher during the cooling phase when compared to the rewarming phase.ConclusionThe differences between oesophageal and rectal temperatures do not result in any clinical effects. Temperature control during hypothermia can be done with either an oesophageal probe or a rectal probe; however, in order to reduce the risk of inadequate cooling due to a defective or dislocated probe, it is safer to use both probes simultaneously.Abstract PO-0718 Figure 1Oesophageal temperature, rectal temperature, surface temperature and zero heat flow temperature during 72 h of hypothermic treatment followed by the rewarming period[Figure omitted.
