The objective of this study was to explore the umbilical cord separation time, predictors, and healing complications from birth until the newborn was one month old.
A quantitative longitudinal observational analytical study by stratified random sample was adopted.
Public health system hospitals in southern Spain and at newborns' homes.
Between April 2016 and December 2017, the study included 106 neonates born after 35-42 weeks of gestation whose umbilical cord was cured with water and soap and dried later as well as newborns without umbilical canalisation whose mothers enjoyed a low-risk pregnancy.
The data collection procedure comprised two blocks: from birth to the time of separation of the umbilical cord and from cord separation to the first month of life of the newborn. Umbilical cord separation time was measured in minutes; socio-demographic and clinical characteristics were measured by means of questionnaires, and the external diameter of the umbilical cord was measured using an electronic stainless-steel calliper and trailing roller.
The mean umbilical separation time: 6.61 days (±2.33, IC 95%:6.16-7.05). Incidence of omphalitis was 3.7%; granuloma was 8.6%. Separation time predictors were wetting recurrence, birth weight, intrapartum antibiotics, birth season, and Apgar < 9 (R2 = 0.439 F: 15.361, p <0.01).
The findings support the World Health Organization recommendations: dry umbilical cord cares is a safe practice that soon detaches the umbilical cord, taking into account the factors studied that will vary the length of time until the umbilical cord is separated.
本研究旨在探讨新生儿脐带分离时间、预测因素以及从出生到新生儿一个月时的愈合并发症。
采用分层随机抽样的定量纵向观察分析研究。
西班牙南部的公共卫生系统医院和新生儿家中。
2016 年 4 月至 2017 年 12 月期间，本研究纳入了 106 名胎龄 35-42 周后出生的新生儿，其脐带用清水和肥皂处理后干燥，以及脐带未结扎而母亲妊娠风险较低的新生儿。
数据收集过程包括两个阶段：从出生到脐带分离以及从脐带分离到新生儿出生后第一个月。脐带分离时间以分钟为单位进行测量；通过问卷调查测量社会人口统计学和临床特征，使用电子不锈钢卡尺和滚轮测量脐带的外径。
平均脐带分离时间为 6.61 天（±2.33，95%置信区间：6.16-7.05）。脐炎发生率为 3.7%；肉芽肿为 8.6%。脐带分离时间的预测因素包括再次浸湿、出生体重、产时抗生素、分娩季节和 Apgar<9（R2=0.439，F：15.361，p<0.01）。
这些发现支持世界卫生组织的建议：干燥脐带护理是一种安全的做法，可使脐带很快脱落，同时考虑到研究中所研究的因素会影响脐带分离的时间长度。
