世界早产儿日 | 有爱有未来——多力姆守护脆弱小生命
  2024/11/17| 阅读次数:265

早产儿是指胎龄小于37周出生的新生儿,为倡导人们更多关注早产儿的生存与发展,便将每年11月17日设立为世界早产儿日。


“有爱,有未来”是世界早产儿日的中文永恒主题,旨在呼吁全社会关爱早产儿及其家庭,提高早产儿生命质量,促进母婴健康。


01
脆弱的早产儿


早产儿是指不足37周的新生儿,不论出生体重多少,孕周越小,各系统发育越不成熟,出现健康问题的风险就越高。


首先由于他们的肺部发育不完善,肺不能完全地膨胀,影响正常的呼吸,很容易出现缺氧,甚至因呼吸窘迫综合征、呼吸暂停发作而造成死亡。


而且早产儿免疫球蛋白水平低下,皮肤和粘膜屏障功能差,以及需要各种插管等医疗操作,导致感染风险很高,可能发生细菌性或真菌性败血症、肺炎、尿路感染以及脑膜炎等。


其次,他们消化功能差,喂养比较困难,很容易引起低血糖,还可能导致坏死性小肠结肠炎,这是一种严重的肠道疾病,肠壁内膜细胞会受损。


最后,早产儿还存在着发育的风险,可能面临脑瘫、学习困难、视力问题(如早产儿视网膜病变)、听力问题、牙齿问题、行为和心理健康问题以及持续的健康问题,这对于早产儿、妈妈和其家属都是很大的难题。

预防先兆早产很关键

虽然现在医疗技术发达,很多早产儿都能平安长大,但为了避免这种风险,预防孕妇先兆早产才是最关键的事情。


导致早产的原因有很多,包括感染、胎膜早破、子宫膨胀过度及胎盘因素、妊娠合并症与并发症、子宫畸形、宫颈机能不全等。


既往有早产史或有晚期流产史、宫颈手术史和发育异常、年龄≤17岁或者年龄>35岁的孕妇、妊娠间隔<6个月、多胎妊娠、羊水量异常、辅助生殖妊娠、吸烟、消瘦等均是早产的高危因素。


而早产症状主要包括3点:第一是阴道分泌物改变,比如分泌物增加,尤其是感觉到类似水样的分泌物持续流出,很可能出现了胎膜早破。若是阴道排出血性分泌物,但是量未超过月经量时,可能是出现了先兆早产;


第二个是腹痛、腹胀,当孕妈妈感受到“腹紧、腹硬”样的宫缩感,且频率很高,休息后也不缓解,或/和伴腹痛症状,也要警惕早产;第三个是b超发现宫颈缩短,必要时要进行药物治疗或宫颈环扎以防早产。


03
如遇先兆早产,一定要科学保胎

先兆早产的治疗主要包括药物治疗和产时管理两个方面,其中药物治疗包括以下4种。

1.宫缩剂
目的是抑制子宫收缩来延长孕周,完成糖皮质激素促胎肺成熟的治疗或为实现胎儿宫内转运赢得时间。临床上常用的宫缩抑制剂主要有以下几类:钙离子通道阻滞剂、缩宫素受体拮抗剂、前列腺素合成酶抑制剂等。

其中烯丙雌醇属于17α羟基孕激素类保胎药,可以使胎盘滋养层的内分泌活性增强,提高催产素酶的浓度和活性,能够拮抗前列腺素对子宫产生的刺激作用,从而起到保胎作用。

烯丙雌醇片(多力姆)治疗先兆早产中建议自孕16周起口服多力姆10~15mg/d至36周。另外在宫颈环扎术后、侵入性产前诊断术后可适当加量口服至20~40mg/d。

2.硫酸镁

硫酸镁能降低早产儿的脑瘫风险,而且能减轻34周及以下胎龄早产儿的脑瘫严重程度。

3.糖皮质激素

包括地塞米松、倍他米松,对妊娠24~34+6周,估计1周内早产或早产临产者,推荐使用1个疗程地塞米松或倍他米松。如果1周内未分娩,而再次出现早产表现,可给予第2个疗程。

4.抗生素

对于分娩在即且下生殖道B族溶血性链球菌检测阳性者则需使用抗生素。

除了药物治疗,对于胎龄<32周的早产儿出生后也需要医护人员进行产时处理,包括体温管理、胎盘输血、呼吸管理、喂养等,这些措施可以直接影响新生儿的存活率。

每个宝宝都是独一无二的,早产儿需要更长的时间才能达到,与足月儿相同的生长发育水平,这需要家长和医护人员给予他们更多的耐心和支持。


让我们一起为早产儿的健康成长共同努力,为他们创造一个更加美好的未来!
