Apnea intervals frequently occur in premature infants. Periods of apnea occur more often with decreases in gestational age. Periods of apnea can cause damage to the infant's developing brain and other organs. This study was designed to investigate the preventive effects of caffeine on apnea incidence in higher-risk neonates.
In this single-center randomized control trial study, premature infants with a birth weight of ≤1200 g were eligible for enrollment. Twenty-six infants were randomly assigned to receive 20 mg/kg caffeine, as the loading dose, which was followed by 5 mg/kg daily as the maintenance dose until the 10 day of life; these infants were compared with 26 infants in the control group. Primary outcomes were incidence of apnea, bradycardia, and cyanosis.
Fifty-two infants were enrolled (26 in the caffeine group and 26 in the control group). The preventive effect of caffeine on apnea was significant in these infants. The relative risk for incidence of apnea in preterm neonates with a birth weight of <1200 g was 0.250 (95% confidence interval, 0.097-0.647). Only four infants (15.4%) in the caffeine group developed apnea, compared with 16 (61.5%) in the control group (p = 0.001).
It seems that preventative effects of caffeine on apnea become apparent by using the drug in very premature infants.
呼吸暂停间歇在早产儿中频繁发生。随着胎龄降低,呼吸暂停发作更为常见。呼吸暂停会损害婴儿发育中的大脑和其他器官。本研究旨在探讨咖啡因对高危新生儿呼吸暂停发生率的预防作用。
在这项单中心随机对照试验研究中,出生体重≤1200g的早产儿符合纳入标准。26例婴儿被随机分配接受20mg/kg咖啡因作为负荷剂量,随后每天5mg/kg作为维持剂量,直至出生后第10天;这些婴儿与对照组的26例婴儿进行比较。主要结局为呼吸暂停、心动过缓和发绀的发生率。
共纳入52例婴儿(咖啡因组26例,对照组26例)。咖啡因对这些婴儿呼吸暂停的预防作用显著。出生体重<1200g的早产儿呼吸暂停发生率的相对风险为0.250(95%置信区间,0.097 - 0.647)。咖啡因组仅4例婴儿(15.4%)发生呼吸暂停,而对照组为16例(61.5%)(p = 0.001)。
似乎在极早产儿中使用咖啡因对呼吸暂停的预防作用较为明显。
