Complications of preterm birth cause more than 1 million deaths each year, mostly within the first day after birth (47%) and before full post-natal stabilisation. Kangaroo mother care (KMC), provided as continuous skin-to-skin contact for 18 h per day to fully stabilised neonates ≤ 2000 g, reduces mortality by 36-51% at discharge or term-corrected age compared with incubator care. The mortality effect of starting continuous KMC before stabilisation is a priority evidence gap, which we aim to investigate in the eKMC trial, with a secondary aim of understanding mechanisms, particularly for infection prevention.
We will conduct a single-site, non-blinded, individually randomised, controlled trial comparing two parallel groups to either early (within 24 h of admission) continuous KMC or standard care on incubator or radiant heater with KMC when clinically stable at > 24 h of admission. Eligible neonates (n = 392) are hospitalised singletons or twins < 2000 g and 1-24 h old at screening who are mild to moderately unstable as per a trial definition using cardio-respiratory parameters. Randomisation is stratified by weight category (< 1200 g; ≥ 1200 g) and in random permuted blocks of varying sizes with allocation of twins to the same arm. Participants are followed up to 28 ± 5 days of age with regular inpatient assessments plus criteria-led review in the event of clinical deterioration. The primary outcome is all-cause neonatal mortality by age 28 days. Secondary outcomes include the time to death, cardio-respiratory stability, hypothermia, exclusive breastfeeding at discharge, weight gain at age 28 days, clinically suspected infection (age 3 to 28 days), intestinal carriage of extended-spectrum beta-lactamase producing (ESBL) Klebsiella pneumoniae (age 28 days), and duration of the hospital stay. Intention-to-treat analysis will be applied for all outcomes, adjusting for twin gestation.
This is one of the first clinical trials to examine the KMC mortality effect in a pre-stabilised preterm population. Our findings will contribute to the global evidence base in addition to providing insights into the infection prevention mechanisms and safety of using this established intervention for the most vulnerable neonatal population.

早产儿并发症每年导致超过 100 万人死亡,其中大部分发生在出生后第一天(47%)和完全产后稳定之前。袋鼠式护理(KMC),即每天持续 18 小时的皮肤对皮肤接触,适用于体重≤2000 克的完全稳定新生儿,可以将死亡率与保温箱护理相比降低 36-51%。在稳定前开始持续 KMC 的死亡率影响是一个优先的证据空白,我们旨在 eKMC 试验中对此进行研究,次要目标是了解机制,特别是感染预防。
我们将进行一项单中心、非盲、个体随机、对照试验,比较两组:早期(入院后 24 小时内)连续 KMC 或标准护理(保温箱或辐射加热器),对于入院后>24 小时稳定的新生儿,在临床稳定时给予 KMC。符合条件的新生儿(n=392)为住院单胎或双胞胎,体重<2000 克,筛查时年龄为 1-24 小时,根据使用心肺参数的试验定义,属于轻度至中度不稳定。随机化按体重类别(<1200 克;≥1200 克)和大小不同的随机排列块进行分层,双胞胎分配到同一组。参与者随访至 28±5 天龄,定期进行住院评估,在临床恶化时根据标准进行评估。主要结局是 28 天龄时的全因新生儿死亡率。次要结局包括死亡时间、心肺稳定性、低体温、出院时纯母乳喂养、28 天龄时体重增加、临床疑似感染(3-28 天龄)、肠道携带产Extended-spectrum beta-lactamase producing (ESBL) Klebsiella pneumoniae(28 天龄)以及住院时间。所有结局均采用意向治疗分析,调整双胞胎妊娠。
这是首次在稳定前早产儿人群中检验 KMC 死亡率影响的临床试验之一。我们的研究结果将为全球提供证据,此外还将为该最脆弱新生儿人群使用这种既定干预措施的感染预防机制和安全性提供见解。
