BACKGROUND

Umbilical-cord acidemia may indicate perinatal asphyxia and places a neonate at increased risk for hypoxic ischemic encephalopathy (HIE). Our specific aim was to develop a standardized clinical care pathway, ensuring timely identification and evaluation of neonates with umbilical-cord acidemia at risk for HIE.

METHODS

A standardized clinical care pathway to screen inborn neonates ≥36 weeks with abnormal cord blood gases (a pH of ≤7.0 or base deficit of ≥10) for HIE was implemented in January 2016. Abnormal cord blood gases resulted in a direct notification from the laboratory to an on-call physician. Evaluation included a modified Sarnat examination, postnatal blood gas, and standardized documentation. The percentage of neonates in which physician notification, documented Sarnat examination, and postnatal blood gas occurred was examined for 6 months before and 35 months after implementation.

RESULTS

Of 203 neonates with abnormal cord gases in the post–quality improvement (QI) period, physician notification occurred in 92%. In the post-QI period, 94% had a documented Sarnat examination, and 94% had postnatal blood gas, compared with 16% and 11%, respectively, of 87 neonates in the pre-QI period. In the post-QI period, of those evaluated, >96% were documented within 4 hours of birth. In the post-QI period, 15 (7.4%) neonates were cooled; 13 were in the NICU at time of identification, but 2 were identified in the newborn nursery and redirected to the NICU for cooling.

CONCLUSIONS

A standardized screening pathway in neonates with umbilical-cord acidemia led to timely identification and evaluation of neonates at risk for HIE.
