Abstract

Background: Few primary studies have examined the impact of olfactory and gustatory stimulation on premature infants, and variability exists in reported outcomes.

Purpose: To explore the effects of olfactory and gustatory stimulation on feeding outcomes in preterm infants.

Data sources: A literature search was conducted in 4 databases (CENTRAL, PubMed, Embase, CINAHL) from the inception of the databases to May 2024.

Study selection: Randomized controlled trials (RCTs) or quasi-RCTs to explore the effects of olfactory and gustatory stimulation on feeding outcomes in preterm infants were included.

Data extraction: Two reviewers independently extracted data from the included studies and completed the form designed for data extraction.

Results: Eleven RCTs and quasi-RCTs comprising 1009 preterm infants were included. Meta-analysis found that olfactory and gustatory stimulation significantly shortened the time to reach full oral feeds ( days ) (mean difference [MD]: -2.52, 95% confidence interval [CI]: -3.88 to -1.16, P = .0003), while they had no significant differences in time to achieve full enteral feeds ( days ), postmenstrual age (PMA) at the removal of the nasogastric tube ( weeks ), weight at discharge ( grams ), weight gain ( grams ), head circumference at discharge ( cm ), length at discharge ( cm ), total duration of parenteral nutrition ( days ), necrotizing enterocolitis, hospitalization duration ( days ), PMA at discharge ( weeks ).

Implications for practice and research: Large sample, multicenter studies are needed to demonstrate the effectiveness of olfactory and gustatory stimulation on feeding outcomes in preterm infants.

味觉和嗅觉刺激对早产儿喂养结果的影响：系统回顾与元分析》。

背景：目的：探讨嗅觉和味觉刺激对早产儿喂养结果的影响：数据来源：在 4 个数据库（CENTRAL、PubMed、Embase、CINAHL）中进行了文献检索，检索时间从数据库建立之初至 2024 年 5 月：纳入了探讨嗅觉和味觉刺激对早产儿喂养结果影响的随机对照试验（RCT）或准RCT：两名审稿人独立从纳入的研究中提取数据，并填写数据提取表格：结果：共纳入 11 项 RCT 和准 RCT 研究，涉及 1009 名早产儿。Meta 分析发现，嗅觉和味觉刺激可显著缩短婴儿完全口喂的时间（天数）（平均差 [MD]: -2.52, 95% 置信区间 [CI]: -3.88 to -1.16, P = .0003），而在实现完全肠内喂养的时间（天数）、拔除鼻胃管时的月经后年龄（PMA）（周数）、出院时体重（克）、体重增加（克）、出院时头围（厘米）、出院时身长（厘米）、肠外营养总持续时间（天数）、坏死性小肠结肠炎、住院时间（天数）、出院时的 PMA（周数）方面没有显著差异：需要进行大样本、多中心研究，以证明嗅觉和味觉刺激对早产儿喂养效果的有效性。
