Introduction. According to numerous researches, transitory hypothermia is a
part of the neonatological energetic triangle and represents a significant
prognostic factor within morbidity and mortality in newborns with
intrauterine growth retardation (IUGR), that are, due to their
characteristics, more inclined to transitory hypothermia. Objective. The aim
of the study was an analysis of frequency of transitory hypothermia in term
newborns with IUGR, as well as an analysis of frequency of the most frequent
pathological conditions typical of IUGR newborns depending on the presence of
transitory hypothermia after birth (hypoglycaemia, perinatal asphyxia,
hyperbilirubinaemia and hypocalcaemia). Methods. The study included 143 term
newborns with IUGR treated at the Neonatology Ward of the Gynaecology-
Obstetrics Clinic ?Narodni front?, Belgrade. The newborns were divided into
two groups: the one with registered transitory hypothermia - the observed
group, and the one without transitory hypothermia - the control group. The
data analysis included the analysis of the frequency of transitory
hypothermia depending on gestation and body mass, as well as the analysis of
pathological conditions (perinatal asphyxia, hypoglycaemia, hypocalcaemia,
hyperbilirubinaemia) depending on the presence of hypothermia.The analysis
was done by statistical tests of analytic and descriptive statistics.
Results. In morbidity structure dominate hypothermia (65.03%), hypoglycaemia
(43.36%), perinatal asphyxia (37.76%), hyperbilirubinaemia (30.77%),
hypocalcaemia (25.17%). There were 93 newborns in the observed group, and 50
in the control one. Mean value of the measured body temperature was 35.9?C.
20 newborns (32.26%) had moderate hypothermia, and 73 newborns (67.74%) had
mild hypothermia. In the observed group, average gestation was 39.0 weeks,
and 39.6 (p<0.01) in the control group. Average body mass at birth in the
whole group was 2339 g: 2214 g in the observed and 2571 g in the control
group. The frequency of hypoglycaemia in the observed group was 53.8%, and
24% in the control group (p<0.01). In the observed group, the frequency of
pH<7.25 was 38.71%, and 14% in the control group (p<0.05). The frequency of
hyperbilirubinaemia was 38.71% in the observed group, and 16% in the control
group (p<0.01). The frequency of hypocalcaemia was 32.26% in the observed,
and 12% in the control group (p<0.01). Conclusion. Transitory hypothermia in
the first ten hours of life represents a significant risk factor for
deepening hypoglycaemia, asphyxia, hyperbilirubinaemia and hypocalcaemia in
term newborns with IUGR.
