RESUMO
OBJECTIVE: We assessed the association between a short antenatal corticosteroid administration-to-birth interval and neonatal outcome. STUDY DESIGN: A retrospective study was conducted between 2010 and 2020. Eligible cases were singleton preterm live-born neonates born between 24-0/7 and 33-6/7 weeks of gestation and were initiated an ACS course of betamethasone. We divided the first 48 h following the first ACS administration to four time intervals and compared each time interval to those born more than 48 h following ACS administration. The primary outcome was a composite of adverse neonatal outcome, including neonatal mortality or any major neonatal morbidity. RESULTS: A total of 200 women gave birth less than 48 h from receiving the first betamethasone injection, and 172 women gave birth within 2-7 days (48-168 h) from ACS administration. Composite adverse neonatal outcome was higher for neonates born less than 12 h from initial ACS administration compared to neonates born 2-7 days from the first betamethasone injection (55.45% vs. 29.07%, OR 3.45 95% CI [2.02-5.89], p value < 0.0001). However, there was no difference in composite adverse neonatal outcomes between neonates born 12-48 h following ACS administration and those born after 2-7 days. That was also true after adjusting for confounders. CONCLUSIONS: 12-24 h following ACS administration may be sufficient in reducing the same risk of neonatal morbidities as > 48 h following ACS administration. It may raise the question regarding the utility of the second dose of ACS.

Pregnant women with lower back tattoos who wish to have an epidural placed during labour pose a dilemma to anesthesiologists. Clear guidelines have not been established. We reviewed the epidural risks in pregnant women with low back tattoos and have suggested precautionary measures to minimise them. Given the limited information available, and in the absence of a clear evidence-based medical contraindication, an epidural technique should not be excluded in those women with a lower back tattoo.
