Bottom Line: TOSCA resulted easily and safely usable in the DR, allowing reliable noninvasive SaO(2) estimation.Moreover, PtcCO(2) levels were less precise if compared to the conventional transcutaneous monitoring.However, PtcCO(2) measurement by TOSCA was useful as trend-monitoring after stabilization and during transport to NICU.

ABSTRACT
Arterial oxygen saturation (SaO(2)) and partial arterial pressure of carbon dioxide (PaCO(2)) are important respiratory parameters in critically ill neonates. A sensor combining a pulse oximeter with the Stow-Severinghaus electrode, required for the measurement of peripheral oxygen saturation (SpO(2)) and transcutaneous partial pressure of carbon dioxide (PtcCO(2)), respectively, has been recently used in neonatal clinical practice (TOSCA(500Ò)Radiometer). We evaluated TOSCA usability and reliability in the delivery room (DR), throughout three different periods, on term, late-preterm, and preterm neonates. During the first period (period A), 30 healthy term neonates were simultaneously monitored with both TOSCA and a MASIMO pulse oximeter. During the second period (period B), 10 healthy late-preterm neonates were monitored with both TOSCA and a transcutaneous device measuring PtcCO(2) (TINA(Ò) TCM3, Radiometer). During the third period (period C), 15 preterm neonates were monitored with TOSCA and MASIMO after birth, during stabilization, and during transport to the neonatal intensive care unit (NICU). Blood gas analyses were performed to compare transcutaneous and blood gas values. TOSCA resulted easily and safely usable in the DR, allowing reliable noninvasive SaO(2) estimation. Since PtcCO(2) measurements with TOSCA required at least 10 min to be stable and reliable, this parameter was not useful during the early resuscitation immediately after birth. Moreover, PtcCO(2) levels were less precise if compared to the conventional transcutaneous monitoring. However, PtcCO(2) measurement by TOSCA was useful as trend-monitoring after stabilization and during transport to NICU.

Mentions: Of the 30 neonates born during period A (GA: 37.9 ± 1 weeks; BW: 3138 ± 459 g, 13 males and 17 females), none needed respiratory support at birth. No differences between SpO2TOSCA and SpO2MASIMO were detected at all time points (Figure 2(top)). For both monitors, data were available 60 s after sensor placement. The clipping of the TOSCA sensor was easy. Sensor repositioning was necessary in 16/30 registrations (53%) with TOSCA and in 5/30 registrations (16.6%) with MASIMO (p = 0.003). After sensor repositioning, time required to obtain a stable reading was shorter for TOSCA than for MASIMO (about 10 vs. 15 s). PtcCO2TOSCA progressively increased during the whole monitoring (Figure 2(bottom)).
