Zusammenfassung: | Objective
To correlate arterial umbilical cord gas (aUCG) and infant blood gas with severity of neurological injury.
Study design
Retrospective single-site study of infants evaluated for therapeutic hypothermia. Clinical neurological examination and a validated MRI scoring system were used to assess injury severity.
Results
Sixty-eight infants were included. aUCG base deficit (BD) and lactate correlated with infant blood gas counterparts (
r
= 0.43 and
r
= 0.56, respectively). aUCG and infant pH did not correlate. Infant blood gas lactate (
R
ADJ
2
= 0.40), infant BD (
R
ADJ
2
= 0.26), infant pH (
R
ADJ
2
= 0.17), aUCG base deficit (
R
ADJ
2
= 0.08), and aUCG lactate (
R
ADJ
2
= 0.11) were associated with clinical neurological examination severity. aUCG and infant blood gas measures were not correlated with MRI score.
Conclusion
Metabolic measures from initial infant blood gases were most associated with the clinical neurological examination severity and can be used to evaluate hypoxic-ischemic cerebral injury risk. |
