Scalp Sampling for Fetal Surveillance

Biosampling for Markers of Hypoxia in Fetal Blood Scalp Sampling During Labor

The purpose of this study is to compare lactate and total acid-base status in fetal scalp blood with lactate and total acid-base status in maternal blood and amniotic fluids to provide information on how lactate and base deficit correlates with scalp samples.

Furthermore, the investigators want to study whether angiogenic factors in fluids above may be a possible marker of asphyxia during labor.

Inclusion Criteria:

• All deliveries eligible for fetal blood sampling

Exclusion Criteria:

• Non Swedish speaking
• Those who decline to participate in the study
