To assess the safety of surfactant administration prior to transport of premature infants.
DESIGN/METHODS: We performed a retrospective review of 24- to 34-weeks premature infants admitted to the Newborn Intensive Care Unit (NICU) between July 1, 1999 and September 30, 2004. Outcome measures were the presence of hyperventilation (PCO2 <40 mm Hg) and/or pneumothorax on admission to the NICU. Factors associated with the presence of hyperventilation and pneumothorax were identified.
955 infants born at 24 to 34 weeks' gestation were admitted to the NICU during the study period. 217 (22.7%) received surfactant prior to transport within 48 hours of birth. The incidence of hyperventilation was 18.9%. Hyperventilated infants had longer transport times, lower birth weights, and lower PCO2 on blood gases obtained prior to transport. Pneumothorax occurred in six subjects (2.9%). Neonates with pneumothorax had lower APGAR scores.
We found the administration of surfactant prior to transport to be safe as evidenced by a low incidence of pneumothorax. Pneumothorax was more likely to occur in infants who needed significant resuscitation at birth. The incidence of hyperventilation appeared to be high and was inversely associated with birth weight.
评估在转运早产婴儿之前给予表面活性剂的安全性。
设计/方法:我们对1999年7月1日至2004年9月30日期间入住新生儿重症监护病房(NICU)的24至34周早产婴儿进行了回顾性研究。观察指标为入住NICU时是否存在通气过度(PCO2<40 mmHg)和/或气胸。确定与通气过度和气胸存在相关的因素。
在研究期间,955名妊娠24至34周出生的婴儿入住了NICU。217名(22.7%)在出生后48小时内转运前接受了表面活性剂治疗。通气过度的发生率为18.9%。通气过度的婴儿转运时间更长、出生体重更低,且在转运前采集的血气中PCO2更低。6名受试者(2.9%)发生了气胸。气胸新生儿的阿氏评分更低。
我们发现转运前给予表面活性剂是安全的,气胸发生率低证明了这一点。气胸更有可能发生在出生时需要大量复苏的婴儿中。通气过度的发生率似乎较高,且与出生体重呈负相关。
