“…The first studies using fetal pulse oximetry demonstrated that fetal SpO 2 was B58 ± 10% during labor. 40 The rate of change from fetal to neonatal values after birth has been demonstrated by multiple investigators to be more gradual than previously believed, with actual SpO 2 values reaching the expected neonatal levels after 5 to 15 min of life. [41][42][43][44][45] House et al 46 reported that average oxygen saturation was 59% at 1 min, 68% at 2 min, 82% at 5 min and 90% at 15 min.…”

In an effort to determine the actual conduct of neonatal resuscitation and the errors that may be occurring during this process, we developed a method of video recording neonatal resuscitations as an ongoing quality assurance project. We initiated video recordings of resuscitations using simple video recorders attached to an overhead warmer and reviewed the resultant tapes during biweekly quality improvement meetings. We also added the continuous recording of analog information such as heart rate, oximeter values, fraction of inspired oxygen and airway pressure. We subsequently developed a checklist that includes a preresuscitation briefing and a postresuscitation debriefing, all of which are reviewed at the same time as the video recording. We have examined the use of oxygen in the very preterm infant, the effectiveness of bag and mask ventilation, including the detection of airway obstruction during such ventilation, intubation in the delivery area and environment. In addition, we have trained our teams and leaders using Crew Resource Management and focused on improved communication. The availability of a dedicated room for resuscitation allows an increased ambient environment and the ability to provide a userfriendly setting similar to the neonatal intensive care unit to optimize performance. There are numerous opportunities for improving team and leader performance and outcomes following neonatal resuscitation. Further prospective studies are required to evaluate specific interventions.

“…Zuverlässi-ge präduktale Sättigungswerte lassen sich bei über 90 % der gesunden Neugeborenen, etwa 80 % der Frühgeborenen und 80-90 % der Neugeborenen, die Reanimationsmaßnahmen benötigten, innerhalb von 2 min nach der Geburt ableiten [167]. Unbeeinträchtigte, reife Neugeborene haben unter der Geburt eine arterielle Sauerstoffsättigung (S p O 2 ) von etwa 60 % (gemessen auf Normalhöhennull) [169]. Diese steigt innerhalb von 10 min auf Werte über 90 % an (.…”

“…The critical Spo2 value in the human fetus is not known. In a multi centre study, Dildy et al [13] reported a wide range of Spo2 values (30-81%) in the human fetus with normal outcome. In fetuses with abnormal delivery and outcome, such as unreassuring fetal heart rate, low Apgars and low umbilical arteiy pH, the average saturation did not appear to be lower.…”

Objective: To determine if oxygen saturation measurement with pulse oximetry (Spo2) in combination with cardiotocograghy (CTG), improves the assessment of the intrapartum fetal condition. Study Desig?2: Four expert obstetricians individually evaluated 119 cases that were monitored during labor; during the first session the CTG data were available, and in the second session CTG and Spo2 data were evaluated. They were instructed to indicate the need for intervention and to estimate the umbilical artery pH. Results: In the non-acidotic group (umbilical artery pH >7.15, n = 112) the average(±S.D.) number of interventions decreased from 27(±17) to 16(±9) when Spo2 was available. This reduction in number of interventions resulted in an significantly increased specificity for two referees. In the acidotic group (n = 7) the average number of interventions also decreased, from 6( ± 2) to 4( ± 2), and as a consequence the sensitivity decreased. The pH estimate based on CTG + Spo2 was higher in both acidotic and non-acidotic fetuses than the estimated pH based on CTG alone. Conclusion: In this study all referees intervened less frequently when Spo2 was used as an adjunct to CTG. This resulted in fewer unnecessary operative interventions, but may also lead to unidentified fetal acidosis. The number of acidotic newborns (n = 7) was too small, however, to draw definite conclusions. Larger studies should address the efficacy of Spo2 in detecting fetal compromise before clinical use can be advocated. © 1997 Elsevier Science Ireland Ltd.
