OBJECTIVE
To analyse impact of delayed cord clamping (DCC60sec) on cerebral regional tissue oxygenation (crSO2) and fractional tissue oxygen extraction (cFTOE) in spontaneously breathing preterm neonates during the first 15 min after birth.
METHODS
Two-centre observational study, crSO2 and cFTOE was monitored in neonates with DCC60sec or early cord clamping (ECC < 30 s).
RESULTS
Seventy-six infants (birth weight and gestational age 1736 ± 508 g and 31.8 ± 2.5 weeks) were included. DCC was associated with lower initial crSO2 and higher cFTOE and lower initial Apgar-score and heart rate.
CONCLUSION
Attending practitioners should be aware that DCC might impact initial immediate transition in spontaneously breathing preterm neonates.
目的
分析延迟脐带结扎（DCC 60秒）对出生后前15分钟自主呼吸早产儿脑局部组织氧合（crSO2）和组织氧摄取分数（cFTOE）的影响。
方法
双中心观察性研究，对采用DCC 60秒或早期脐带结扎（ECC＜30秒）的新生儿监测crSO2和cFTOE。
结果
纳入76例婴儿（出生体重和胎龄分别为1736±508克和31.8±2.5周）。DCC与较低的初始crSO2、较高的cFTOE、较低的初始阿氏评分和心率相关。
结论
执业医师应意识到DCC可能会影响自主呼吸早产儿的初始即刻过渡。
