Abstract
BACKGROUND: Therapeutic hypothermia is a method of treatment in newborns with hypoxic ischemic encephalopathy. Hypothermia should be initiated no later than 6 h after birth. The purpose of this study was to evaluate the quality of the passive therapeutic cooling during neonatal transport. PURPOSE: The study aims to evaluate the efficiency of our transport in maintenance of target body temperature during transport. METHODS: We conducted a 10-year retrospective study in neonates, transported by helicopter or ambulance, who received therapeutic passive-induced hypothermia during transport to the Department of Pediatric Surgery and Intensive Therapy at the University Medical Centre Ljubljana between September 1, 2006, and December 31, 2016. RESULTS: Out of 68 transported newborns, 57 met the criteria for therapeutic induced hypothermia. Eight out of 51 (15.7%) were within therapeutic temperature zone before start of transport while 30 out of 57 (52.6%) were within therapeutic temperature zone at the end of transport. There was a negative correlation between the duration of transport and temperature at the admission (ρ = - 0.306; p = 0.026). A positive correlation was found between the body temperature before and at the end of transport (ρ = 0.410; p = 0,003). A positive correlation between axillary and rectal temperature on admission was found (ρ = 0,832; p < 0,0005). The type of transport, meteorological season, or gender differences did not affect any of measured parameters. Newborns who received chest compression had lower temperature. CONCLUSION: Therapeutic temperature zone during transport was achieved in 52.6% of transported neonates. Axillary temperature positively correlated with rectal temperature on admission.
