Limb-lead electrocardiography versus pulse oximetry for heart rate monitoring during neonatal resuscitation in the delivery room: A prospective observational study from developing country.

This article focuses on comparing limb-lead electrocardiography (ECG) and pulse oximetry (PO) for heart rate monitoring during neonatal resuscitation in the delivery room. Conducted in a tertiary hospital in India with term and late pre-term neonates, the study found that while ECG lead placement took slightly longer than PO probe application, ECG provided a significantly faster and more reliable heart rate display (mean 25.3 seconds vs. 44.3 seconds, p < 0.0001). Limb-lead ECG was favored for its ease of application without interfering with resuscitation procedures, despite minor delays in neonates with vernix or meconium-stained skin. The authors suggest that ECG serves as a valuable adjunct to pulse oximetry, which also measures oxygen saturation, and recommend combined use for comprehensive monitoring during neonatal resuscitation.
