Systematic Review of the Effectiveness of Involving Parents During Painful Interventions for Their Preterm Infants

ObjectiveTo systematically review the literature related to the effectiveness of parents’ active involvement during painful interventions for their preterm infants.Data SourcesWe performed a systematic search of PubMed, EMBASE/Ovid, CINAHL, Livivio, and PsycInfo using the keywords “preterm infants,” “pain,” and “parents.”Study SelectionArticles were eligible for inclusion if they were published between 2000 and 2021 and reported randomized controlled trials (RCTs) in which preterm infants underwent painful interventions, and parents were present and actively involved in pain-reducing measures.Data ExtractionWe used the Consolidated Standards of Reporting Trials (CONSORT) checklist for RCTs for data extraction. We assessed methodologic quality using critical appraisal for RCTs according to the Joanna Briggs Institute.Data SynthesisIn total, 22 articles met the inclusion criteria. These articles reported 19 studies focused on kangaroo/skin-to-skin care, one focused on breastfeeding, and two focused on facilitated tucking. The methods used to evaluate pain in the infant varied substantially. Overall, kangaroo/skin-to-skin care and facilitated tucking resulted in clinically and statistically significant decreases in pain. For breastfeeding, effectiveness was linked to a more mature sucking pattern of the preterm infant.ConclusionThe current evidence suggests that involving parents in pain-reducing measures during painful interventions for their preterm infants is beneficial. However, more research is needed for the different methods of involving parents in pain-reducing measures.     

窒息鼠脑组织型纤溶酶原激活物活性变化与脑水肿的关系

目的：探讨窒息对鼠脑分泌组织型纤溶酶原激活物（TPA）的影响与脑水肿的关系。方法：通过“延迟剖宫产术”致胎鼠宫内窘迫，实验分空白对照组，窒息15min组，窒息30min组，窒息15min复氧30min组，窒息30min复氧30min五个实验组，每组各取8例测试脑组织TAP的活性及含水量，结果：窒息后鼠脑TPA活性与含水量均升高（P＜0．01），结论：窒息可致TAP活性增高，同时发生脑水肿，高活性的TPA可能是脑缺氧缺血致不可逆神经元损伤的一个重要媒介。     

窒息新生儿出生体重与血清同型半胱氨酸关系

目的探讨窒息新生儿出生体重对其血清中高同型半胱氨酸血症及低叶酸水平的关系。方法同期出生的新生儿分为正常组和窒息组,并分别分为正常体重及低体重组。应用酶联免疫吸附实验方法检测血清中Hcy水平。应用放射免疫法测定血中叶酸浓度。结果窒息组正常体重儿血清同型半胱氨酸为(10.50±2.19)μmol/L,低体重儿为(15.82±2.51)μmol/L,对照组正常体重儿血清同型半胱氨酸为(7.73±0.61)μmol/L,低体重儿为(7.45±0.43)μmol/L。在窒息组内低体重儿血清同型半胱氨酸水平明显高于正常体重儿(P<0.001),且窒息低体重组儿血清同型半胱氨酸水平明显高于正常对照组儿,不论其出生体重如何(P<0.001)。血清叶酸水平检测结果显示窒息组正常体重儿血清叶酸水平为(2.74±0.16)μg/L,低体重儿为(2.29±0.25)μg/L,对照组正常体重儿血清叶酸为(3.33±0.23)μg/L,低体重儿为(3.02±0.29)μg/L。窒息组患儿无论正常体重儿还是低体重儿其血清叶酸水平变化均不显著(P>0.05)。结论缺氧窒息合并低出生体重者血清同型半胱氨酸水平显著升高。     

Sulphasalazine and Sulphapyridine Serum Levels in Children to Mothers Treated with Sulphasalazine during Pregnancy and Lactation

ABSTRACT. Serum concentrations of sulphasalazine and sulphapyridine were measured during the first week of life in 15 children whose mothers had been on sulphasalazine during pregnancy. The serum concentrations of sulphapyridine and sulphasalazine were similar in the children and their mothers at delivery. The elimination rate of the drugs in the newborn children was slow but the concentrations were not so high that a bilirubin displacing effect could be expected. In eight mothers who were breast-feeding and taking sulphasalazine, analyses were done of mothers'serum, breast-milk and serum from their children. The results showed that the amount of sulphasalazine and sulphapyridine transferred to the child via the breast-milk is negligible with regard to the risk of kernicterus. It is concluded that a woman in need of sulphasalazine treatment can continue the medication throughout pregnancy and lactation without risk of development of kernicterus in her child. Only term infants without haemolytic disease were included in the study. Thus our conclusion is not necessarily valid for the prematurely born child or the child with haemolytic disease.     

纯氧和空气复苏患儿24个月随访观察

目的 探讨纯氧和空气复苏对新生儿发育的影响,为新生儿复苏用氧选择提供依据.方法 对2005年1月-2007年1月在保定市妇幼保健院进行窒息复苏的30例患儿在24个月时进行随访,依据复苏用氧浓度分为纯氧复苏组(20例)和空气复苏组(10例),内容包括出生时胎龄、出生体重、身长、头围、阿氏评分(1 min,5 min)、心率(1 min,5 min)、随访时体重、身长、头围及运动发育标志(坐、爬、站、走时间).结果 出生时患儿身体数据差异无统计学意义,24个月随访,患儿身高、体重、头围及运动发育标志差异均无统计学意义(P>0.05).结论 空气复苏对新生儿窒息患者是安全有效的.     

Arachidonic acid metabolites in CSF in hypoxic-ischaemic encephalopathy of newborn infants

The aim of this study was to evaluate the cerebral synthesis of eicosanoids in the asphyctic newborn and to investigate the relation between the prostanoid profiles in cerebrospinal fluid (CSF) and the appearance and severity of hypoxic-ischaemic encephalopathy (HIE). Levels of 6-keto-PGF _1-α, TXB₂, PGE₂ and PGF_2-α in CSF were measured in 40 full term newborns during the first day of life. Thirty of these newborns had birth asphyxia and were divided into three groups: 10 without HIE, 12 with mild HIE and 8 with moderate-severe HIE. They were compared to a control group of 10 non-hypoxic newborns. Determinations of the metabolites in CSF were performed by RIA and expressed as pg/ml (mean ± SD). The CSF TXB₂ (thromboxane A₂ metabolite) in asphyxiated newborns was always higher than in the control group (28.12 ± 10.6), and related to the severity of HIE ( p = 0:005): without HIE (50.84 ± 16.4; p = 0:02), mild HIE (80.65 ± 12.64; p ± 0:01) and moderate-severe HIE (178.14 ± 20.5; p < 0:01). The CSF 6-keto-PGF _1-α (prostacyclin metabolite) in asphyxiated newborns was always higher than in the control group (80.55 ± 12.56), but indirectly related to the severity of HIE: without HIE (240.95 ± 28.12; p < 0:01), mild HIE (183.65 ± 30.1; p < 0:01) and moderate-severe HIE (140.55 ± 25.12; p < 0:01). In the moderate-severe HIE group, the increase in TXB₂ was higher than the rise in 6-keto-PGF _1-α.

脐带缠绕与新生儿窒息及分娩方式

目的 探讨脐带缠绕与新生儿窒息及分娩方式的关系。方法 回顾性分析2001年5月于2002年4月脐带缠绕246例，与同期分娩的无脐带缠绕者800例进行对照性研究。结果 脐带缠绕组新生儿窒息和剖宫产率高于对照组，差异有显著性（P＜0．05，P＜0．01）；脐带越长，脐带缠绕率越高；脐带长度正常，新生儿窒息率低，脐带过长及过短，新生儿窒息率高；脐带缠绕周数越多，新生儿窒息率越高，差异有显著性（P＜0．01）。结论 脐带缠绕与脐带长度有关，脐带缠绕可导致新生儿窒息，故对脐带缠绕者应加强产前诊断及产时监护。

目的探讨预防新生儿窒息的措施，以降低新生儿窒息的发生率。方法收集我院124例新生儿窒息的临床资料，分析发病的相关高危因素。结果窒息的相关因素依次为：早产因素34例居首位，占27．4％；羊水过少占14．5％；胎位异常占10．5％；产程异常占9．7％；脐带因素（缠绕、脱垂及过短）占8．9％；巨大儿占8．9％；胎盘早剥及前置胎盘占6．5％；妊娠高血压综合征占5．6％；宫内生长迟缓（IUGR）占3．2％。结论加大孕产妇分级管理的力度，加强孕期保健和产前检查，适时纠正臀位，尽量减少早产，及早发现和正确处理胎儿宫内窘迫，是降低新生儿重度窒息的有效措施。     

Outbreak of Coxsackievirus A-14 Meningitis among Newborns in a Maternity Hospital Ward

ABSTRACT. During the late winter of 1983, 16 newborns with vague symptoms of failure to thrive, reluctance to feed and a slight rise in body temperature, were found to have meningitis caused by Coxsackievirus A-14. The cerebrospinal fluid showed pleocytosis with polymorphonuclear cells in excess but was otherwise normal. The clinical course was uneventful in all infants, but two of them demonstrated clinical signs of incipient cerebral oedema during the acute phase of the illness. An electroencephalogram (EEG) during the initial course of the disease and at nine months of age was normal in all. During a follow-up period of 21/2 years they all developed normally and no sequelae were noted. The presentation also demonstrates the usefulness of Vero cells for the propagation of the responsible virus.
