To describe and compare the intra- and interexaminer reliability of four techniques for measuring length in full-term newborns and to determine whether the different techniques yield significantly different measurements.
A descriptive study, describing the intra- and interexaminer reliability of four length measurement techniques: crown-heel, supine, paper barrier, and Neo-infantometer. The nurses were blind to their own and to the other nurse's measurements. The order of the nurses and the order in which the measurements were obtained was randomized.
Mothers' rooms in a university hospital.
Thirty-two healthy full-term newborns.
Length measurements using four different length techniques were obtained twice each by two experienced neonatal nurses.
To measure the intra- and interexaminer reliability, the following statistics were calculated: mean absolute differences, standard deviations, technical error of measurement; percentage less than .5 and 1.0 cm, and percentage of error.
Intra- and interexaminer differences were significantly larger when examiners used the crown-heel measurement technique. Although the intra- and interexaminer reliability of length measurements obtained with the supine, paper barrier, and Neo-infantometer techniques did not differ significantly, the amount of error in these measurements was large.
Measurements obtained using the crown-heel technique are significantly less reliable than measurements obtained using the supine, paper barrier, or Neo-infantometer techniques.
描述并比较四种测量足月儿身长技术的检查者内和检查者间可靠性，并确定不同技术所得到的测量值是否存在显著差异。
一项描述性研究，描述四种身长测量技术（顶跟、仰卧位、纸屏障和新生儿测长仪）的检查者内和检查者间可靠性。护士对自己及另一名护士的测量结果不知情。护士顺序及测量顺序均随机安排。
一所大学医院的产妇病房。
32名健康足月儿。
两名经验丰富的新生儿护士分别使用四种不同的身长测量技术对每名新生儿测量两次。
为测量检查者内和检查者间可靠性，计算以下统计量：平均绝对差值、标准差、测量技术误差；小于0.5厘米和1.0厘米的百分比以及误差百分比。
当检查者使用顶跟测量技术时，检查者内和检查者间差异显著更大。虽然仰卧位、纸屏障和新生儿测长仪技术所获得的身长测量的检查者内和检查者间可靠性无显著差异，但这些测量中的误差量很大。
使用顶跟技术获得的测量结果远不如使用仰卧位、纸屏障或新生儿测长仪技术获得的测量结果可靠。
