Objective To investigate the characteristics of arterial blood gas analysis, time of mechanical ventilation and hospital stay in different age patients with Pirre Robin sequence (PRS). Methods Sixty children with III-grade PRS were divided into two groups according to their age, as neonate group and non-neonate group. The blood samples were collected from radial artery after admission for blood gas analysis, the characteristics of pH value, partial pressure of carbon dioxide (PCO₂), partial pressure of blood oxygen (PO₂), bicarbonate ion (HCO^-₃), base excess (BE), lactic acid (Lac), anion gap (AG) , alveolar artery oxygen pressure difference (A-aDO₂) , postoperative mechanical ventilation time and hospital stay were compared between the two groups. Results The levels of PCO₂, HCO^-₃, BE, Lac and A-aDO₂ in neonate group were higher than those in non-neonate group, and the levels of PO₂ and AG in non-neonate group were higher than those in neonate group. The pH value, PO₂ and AG of the two groups were in the normal range. Post-operative mechanical ventilation time and hospital stay were positively correlated with Lac and negatively correlated with age. Conclusions In different age groups, the results of arterial blood gas analysis in PRS children were different, and the time of mechanical ventilation and hospital stay were longer in higher Lac level and younger patients with PRS.
