Clinical Research of Arterial Blood Gas Analysis for Neonatal Asphyxia

Objective: To explore the clinical value of arterial blood gas analysis in the diagnosis of neonatal asphyxia. Method: Choose 40 infants born from October, 2013 to April, 2014 in our hospital with 1 min Apgar score ≤ 7 as asphyxia group, within which 3 < 1 min Apgar score ≤ 7 as mild asphyxia group, Apgar ≤ 3 as severe asphyxia group; at the same time, choose 50 infants with 1 min Apgar score ≥ 8 points, and without symptoms of asphyxia, relatively stable as contrast group. One hour after the infants born, we carry out an analysis of blood gas, and make a relevant analysis with Apgar evaluation. Results: The result comes out that compared with the contrast group, infants in asphyxia group have decreased value in PH, PO2, BE, 3 − HCO and Lactic acid, and have increased value in PCO2. While, severe asphyxia group has more obvious changes in values. Conclusion: Arterial blood gas analysis, together with Apgar evaluation can help to diagnose neonatal asphyxia. What’s more, they can reflect the quality and severity of HIE more objectively, and help to predict the prognosis of neonatal.
