To examine predictive relationships among intrapartum maternal fluid intake, birth type, neonatal output, and neonatal weight loss during the first 48 hours after birth.
Prospective descriptive design.
Women's center of a 900-bed regional acute care facility with 6,700 births per year.
A convenience sample of 200 mother/neonate dyads. The Optimality Index of Murphy and Fullerton guided the inclusion and exclusion criteria to ensure healthy dyads.
Data collection began in the intrapartum period and concluded with maternal/neonatal discharge. Measures included maternal intrapartum fluid intake from admission to birth, daily neonatal weight, output, and feedings. Data were analyzed via descriptive statistics, tests of significance and multiple regression.
Neonatal weight loss was not significantly related to intrapartum maternal fluid intake. Strong predictors of neonatal weight loss and significant weight loss within the first 48 hours were type of feeding (p=.000) and average number of wet diapers (p=.003).
Variables predictive of neonatal weight loss can facilitate identification of at-risk neonates to prevent significant weight loss. Close monitoring of the number of wet diapers in the first 48 hours and accurate daily weights at birth time can lead to early detection and preventive interventions.
研究分娩期母体液体摄入量、分娩类型、新生儿尿量及出生后48小时内新生儿体重减轻之间的预测关系。
前瞻性描述性设计。
一家拥有900张床位的地区性急症护理机构的妇女中心，每年有6700例分娩。
200对母婴的便利样本。Murphy和Fullerton的最佳指数指导纳入和排除标准，以确保母婴健康。
数据收集从分娩期开始，至母婴出院结束。测量指标包括从入院到分娩时母体的分娩期液体摄入量、新生儿每日体重、尿量和喂养情况。数据通过描述性统计、显著性检验和多元回归进行分析。
新生儿体重减轻与分娩期母体液体摄入量无显著关系。喂养方式（p = .000）和平均湿尿布数（p = .003）是新生儿体重减轻及出生后48小时内显著体重减轻的有力预测因素。
预测新生儿体重减轻的变量有助于识别高危新生儿，以防止显著体重减轻。密切监测出生后48小时内的湿尿布数和准确的出生时每日体重可实现早期发现和预防性干预。
