Abstract:
Objective:To investigate the diagnostic value of umbilical cord blood lactic acid and base excess for multi-organ dysfunction following neonatal asphyxia.Methods:A retrospective analysis was conducted on the clinical data of 244 patients at high risk for perinatal asphyxia who received treatment at Dongyang People's Hospital from January 2021 to December 2023.Based on the presence of organ dysfunction, the infants were divided into three groups: a single organ dysfunction group (Group A, n = 55), a multi-organ dysfunction group (Group B, n = 16), and a no organ dysfunction group (Group C, n = 173). Lactic acid levels and base excess values were compared among the three groups. Receiver operating characteristic curves were used to validate the predictive value of lactic acid and base excess values for organ dysfunction. Results:There were no statistically significant differences in general data among the three groups ( P > 0.05). In Group B, the lactic acid level was 15.10 (13.85, 16.83) mmol/L, and the base excess value was 9.80 (6.65, 15.18) mmol/L. In Group A, the lactic acid level was 7.70 (6.25, 11.70) mmol/L, and the base excess value was 5.70 (3.85, 9.60) mmol/L. In Group C, the lactic acid level was 6.80 (4.30, 9.00) mmol/L, and the base excess value was 4.00 (3.00, 6.50) mmol/L. The lactic acid level and base excess value in Group B were significantly higher than those in both Group A and Group C. Additionally, the lactic acid level and base excess value in Group A were significantly greater than those in Group C ( t = 2.60, 20.19, 2.95, 1.92, all P < 0.05). Receiver operating characteristic curve analysis revealed that the combined assessment of base excess value and lactic acid level was more effective than evaluating each parameter individually in predicting the presence of organ damage and multiple organ dysfunction syndrome. Additionally, the detection of base excess value was found to be superior to the measurement of lactic acid level. The areas under the curve values for the combined assessment of base excess value and lactic acid level for the presence of organ damage and multiple organ dysfunction syndrome were 0.694 and 0.856, respectively. In comparison, the AUC values for base excess value detection were 0.678 and 0.846, while the AUC values for lactic acid level measurement were 0.633 and 0.797, respectively. Conclusions:Umbilical cord blood lactic acid and base excess are correlated with organ dysfunction following neonatal asphyxia, and both parameters have clinical value in assessing organ damage.
