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.
测量了使用硅橡胶真空吸引器分娩患者的脐血气，作为新生儿结局的客观参数，并与自然分娩、产钳分娩或先后使用真空吸引器和产钳分娩患者的这些值进行比较。结果表明，各组间脐血pH值、二氧化碳分压、氧分压、碱剩余或碳酸氢盐值无临床显著差异。这些观察结果让人放心，对于适当选择的足月胎儿，硅橡胶真空吸引器是阴道分娩的一种安全替代方法。
