Numerous scholars have reported that inconsistent levels of incubator humidity in the neonatal intensive care unit (NICU) require attention. Evidence synthesis was needed to identify optimal incubator humidity levels and duration to decrease transepidermal water loss (TEWL) and the potential for infection.
The purpose of this systematic review was to appraise and synthesize the evidence of preterm outcomes related to incubator humidity. The primary aim of this study was to determine how patient outcomes were impacted by incubator humidity levels and duration in premature infants born before 320/7 weeks cared for in the NICU.
METHODS/SEARCH STRATEGY: The foundation of this systematic review was the Joanna Briggs Institute method for systematic reviews. Mefford's theory of health promotion for the preterm infant was used to address the wholeness of the preterm infant's body system. Evidence was classified using the Johns Hopkins evidence-based practice levels and quality of evidence.
Twelve studies met inclusion criteria. The evidence demonstrated that the practice of incubator humidity is warranted; however, it does not come without risks. Microbial growth was increased in high levels of incubator humidity. Unnecessary TEWL was prevented by lowering high levels of incubator humidity after the first week of life, improving skin barrier formation.
Incubator humidity of 60% to 70% in the first week of life was effective in preventing TEWL in infants born 26 weeks or more.
Future incubator humidity research is needed for infants born before 26 weeks.Video Abstract available athttps://journals.lww.com/advancesinneonatalcare/Pages/videogallery.aspx?autoPlay=false&videoId=39.
许多学者报告称，新生儿重症监护病房（NICU）中孵化器湿度不一致需要引起重视。需要进行证据综合，以确定最佳孵化器湿度水平和持续时间，以减少经皮水分流失（TEWL）和感染的可能性。
本系统评价旨在评估和综合与孵化器湿度相关的早产儿结局的证据。本研究的主要目的是确定早产儿在 NICU 中出生前 320/7 周时，孵化器湿度水平和持续时间如何影响早产儿的患者结局。
方法/搜索策略：本系统评价的基础是 Joanna Briggs 研究所的系统评价方法。Mefford 的早产儿健康促进理论用于解决早产儿身体系统的整体性。证据使用约翰霍普金斯循证实践水平和证据质量进行分类。
12 项研究符合纳入标准。证据表明，孵化器湿度的做法是合理的；然而，它并非没有风险。高孵化器湿度会增加微生物生长。通过在生命的第一周后降低高孵化器湿度，可以防止不必要的 TEWL，从而改善皮肤屏障形成。
在生命的第一周内，孵化器湿度为 60%至 70%可有效预防 26 周或以上出生的婴儿的 TEWL。
需要对 26 周前出生的婴儿进行未来的孵化器湿度研究。视频摘要可在以下网址查看：https://journals.lww.com/advancesinneonatalcare/Pages/videogallery.aspx?autoPlay=false&videoId=39.
