To compare the overnight 12-hour oximetry component of 24-hour oximetry recordings with the complete 24-h recording in terms of cardiorespiratory status data in preterm infants.
Preterm infants from the Wellington neonatal intensive care unit underwent a 24-h pulse oximetry recording immediately prior to discharge home. Each recording was edited to resemble a 12-h overnight recording and compared to the full 24-h recording. Differences in a range of cardiorespiratory variables were assessed as to whether they were statistically significant and, if so, likely to be clinically significant.
The nadirs for heart rate and SpO (both P < 0.001), the time spent <80% SpO (P = 0.017) and highest heart rate (P < 0.001) were significantly different between the two recordings. Only the heart rate nadir differed by more than 5%, suggesting that this may be of clinical significance (median (interquartile range) 54 (28-69) for 24-h recording vs. 78 (54-96) for 12-h recording).
The 24-h oximetry reports were clinically similar to 12-h recordings for the majority of variables, and therefore, we suggest that 12-h oximetry studies are sufficient for determining cardiorespiratory status in infants.
比较早产儿 24 小时血氧仪记录的 12 小时夜间血氧测量部分与完整 24 小时记录在心肺状态数据方面的差异。
惠灵顿新生儿重症监护病房的早产儿在出院前立即进行 24 小时脉搏血氧仪记录。对每个记录进行编辑，使其类似于 12 小时夜间记录，并与完整的 24 小时记录进行比较。评估一系列心肺变量的差异是否具有统计学意义，如果具有统计学意义，则评估其是否具有临床意义。
心率和 SpO 的最低值（均 P < 0.001）、SpO < 80%的时间（P = 0.017）和最高心率（P < 0.001）在两种记录之间存在显著差异。只有心率最低值的差异超过 5%，这表明这可能具有临床意义（24 小时记录的中位数（四分位距）为 54（28-69），12 小时记录为 78（54-96））。
对于大多数变量，24 小时血氧仪报告与 12 小时记录在临床上相似，因此，我们建议 12 小时血氧仪研究足以确定婴儿的心肺状态。
