To investigate whether infants < 29 weeks gestation who receive positive pressure ventilation (PPV) immediately after birth with a T-piece have higher oxygen saturation (SpO₂) measurements at 5 minutes than infants ventilated with a self inflating bag (SIB).
Randomized, controlled trial of T-piece or SIB ventilation in which SpO₂ was recorded immediately after birth from the right hand/wrist with a Masimo Radical pulse oximeter, set at 2-second averaging and maximum sensitivity. All resuscitations started with air.
Forty-one infants received PPV with a T-piece and 39 infants received PPV with a SIB. At 5 minutes after birth, there was no significant difference between the median (interquartile range) SpO₂ in the T-piece and SIB groups (61% [13% to 72%] versus 55% [42% to 67%]; P = .27). More infants in the T-piece group received oxygen during delivery room resuscitation (41 [100%] versus 35 [90%], P = .04). There was no difference in the groups in the use of continuous positive airway pressure, endotracheal intubation, or administration of surfactant in the delivery room.
There was no significant difference in SpO₂ at 5 minutes after birth in infants < 29 weeks gestation given PPV with a T-piece or a SIB as used in this study.
研究出生后立即接受 T 型管正压通气(PPV)的<29 周龄婴儿与接受自膨式气囊(SIB)通气的婴儿相比,5 分钟时的氧饱和度(SpO₂)测量值是否更高。
T 型管或 SIB 通气的随机对照试验,出生后立即用 Masimo Radical 脉搏血氧仪从右手/手腕处记录 SpO₂,平均时间为 2 秒,灵敏度最高。所有复苏均以空气开始。
41 名婴儿接受 T 型管 PPV,39 名婴儿接受 SIB PPV。出生后 5 分钟,T 型管和 SIB 组的中位数(四分位间距)SpO₂无显著差异(61%[13%至 72%]与 55%[42%至 67%];P =.27)。T 型管组在产房复苏期间接受氧气的婴儿更多(41[100%]与 35[90%],P =.04)。两组在产房使用持续气道正压通气、气管内插管或表面活性剂方面无差异。
在本研究中,接受 T 型管或 SIB 通气的<29 周龄婴儿出生后 5 分钟时的 SpO₂无显著差异。
