Abstract
SummaryThe limitations of the Apgar score are well recognised, yet it remains the only method widely used for neonatal assessment. Cord blood gas analysis is more accurate and objective, but the misconception that immediate analysis is required limits its use. This study was performed to determine the effect of storing cord blood (in a heparinised syringe at room temperature) on acid-base status. The mean change of pH at 30 min was 0-029 (95 per cent confidence limits: 0-017-0-041). Corresponding values for base deficit were 1-85 and 1-54-2-17 mmol/1. These changes were not clinically significant, and the samples represent the condition at birth. Using this simple method, analysis can be deferred up to 30 min, making it feasible in most obstetric units.
