Cord blood acid-base status in neonates delivered by Silastic vacuum cup extraction: comparison with forceps and spontaneous deliveries.
Umbilical cord blood gases were measured as objective parameters of neonatal outcome in patients delivered by Silastic vacuum extractor and were compared with those values from patients delivered spontaneously, by forceps, or by sequential use of vacuum and forceps. The results demonstrated no clinically significant differences among the groups in cord blood pH, pCO2, pO2, base excess, or bicarbonate values. These observations provide reassurance that the Silastic vacuum extractor is a safe alternative for vaginal delivery of the appropriately selected term fetus.
