Lamaze breathing has been widely used as a breathing training method. Nursing intervention including postural nursing, delivery ball, doula nursing, massage and psychological nursing is usually provided by nurses during labor. A number of clinical studies have investigated the effect of Lamaze breathing training combined with nursing intervention on maternal pain relief and outcomes improvement. But there were some scholars who were against it.
Randomized controlled trials from January 2000 to November 2019 in PubMed, Cochrance Library, Medline, Web of Science, Embase, Chinese Academic Journals, Chinese Biomedical Literature Database, VIP Database, Wanfang Database were searched. Two researchers independently screened the literature according to the criteria. After extracting the data, the researchers used Cochrane system to evaluate the literature quality. Statistical analyses were performed by using Comprehensive Meta Analysis V2 software.
Twenty-two randomized controlled trials conducted on 7035 primiparas were eligible. The results revealed that Lamaze breathing training combined with nursing intervention increased the rate of natural delivery (relative risk [RR] = 2.97, 95% confidence interval [CI] [2.48, 3.56]), shortened the length of labor (-2.604, 95% CI [-3.120, -2.087]), alleviated labor pain (RR = 0.194, 95% CI [0.115, 0.325]) and reduced postpartum bleeding (-2.966, 95% CI [-4.056, -1.877]).
Lamaze breathing training combined with nursing intervention was effective for ameliorating the process and outcomes of childbirth in primiparae and deserves to be promoted and applied in clinical practice.
拉玛泽呼吸法已被广泛用作呼吸训练方法。在分娩过程中，护士通常会提供包括姿势护理、分娩球、导乐护理、按摩和心理护理在内的护理干预。一些临床研究已经调查了拉玛泽呼吸训练结合护理干预对减轻产妇疼痛和改善结局的效果。但也有一些学者对此表示反对。
检索了 2000 年 1 月至 2019 年 11 月期间在 PubMed、Cochrance Library、Medline、Web of Science、Embase、中国学术期刊全文数据库、中国生物医学文献数据库、维普数据库和万方数据库中发表的随机对照试验。两名研究人员根据标准独立筛选文献。提取数据后，研究人员使用 Cochrane 系统评估文献质量。使用 Comprehensive Meta Analysis V2 软件进行统计分析。
有 22 项针对 7035 名初产妇的随机对照试验符合纳入标准。结果表明，拉玛泽呼吸训练结合护理干预增加了自然分娩率（相对风险 [RR] = 2.97，95%置信区间 [CI] [2.48, 3.56]），缩短了产程（-2.604，95% CI [-3.120, -2.087]），减轻了分娩疼痛（RR = 0.194，95% CI [0.115, 0.325]）和减少了产后出血（-2.966，95% CI [-4.056, -1.877]）。
拉玛泽呼吸训练结合护理干预对改善初产妇分娩过程和结局有效，值得在临床实践中推广应用。
