Delayed cord clamping: Impact on fetal cord blood gas analysis

Aust N Z J Obstet Gynaecol. 2022 Apr;62(2):328-331. doi: 10.1111/ajo.13488. Epub 2022 Feb 7.


Both delayed cord clamping (DCC) and cord blood gas (CBG) analysis are recommended practices for preterm births. However, the compliance rates remain lower than expected, with a DCC rate of only 48.9% and CBG sampling of 66.6% in the preterm cohort. DCC was associated with a significant reduction in success rate of paired CBG analysis in both the term and preterm cohort of 8.3% and 7.7% respectively. Our study highlights the difficulty in achieving both recommendations.
