Abstract：
UNASSIGNED: The purpose of this research was to evaluate the differences between rectal and axillary temperature measurements in preterm infants who were born less than 32 weeks\' gestation using digital thermometers upon their admission to the Neonatal Intensive Care Unit (NICU).
UNASSIGNED: Prospective, observational, single centre study. Rectal and axillary temperatures measurements were performed using a digital thermometer. The study examined various maternal and neonatal factors to describe the study group, including the use of prenatal corticosteroids, the occurrence of maternal diabetes and hypertension, a history of maternal prolonged rupture of membranes (PROM), maternal chorioamnionitis, the mode of delivery, along with the neonate\'s gender, birth weight, and gestational age. The Pearson correlation coefficient (R) was calculated to ascertain the linear relationship between the temperatures taken at the rectal and axillary sites. The concordance between the two sets of temperature data was analyzed using the Bland-Altman method.
UNASSIGNED: Eighty infants with a mean gestational age of 28.4 weeks (SD = 2.9) and a mean birth weight of 1,229 g (SD = 456) were included in the study. The mean axillary temperature was 36.4 °C (SD = 0.7), which was lower than the mean rectal temperature of 36.6 °C (SD = 0.6) (p = 0.012). Rectal temperatures surpassed axillary measurements in 59% of instances, while the reverse was observed in 21% of cases. Rectal and axillary temperatures had a strong correlation (Pearson correlation coefficient of 0.915, p < 0.001). Bland-Altman plot showed a small mean difference of 0.1C between the two temperatures measurements but the limits of agreement were wide (+0.7 to -0.6 °C). For hypothermic infants, the mean difference between rectal and axillary temperatures was 0.27 °C, with a wide limit of agreement ranging from -0.5 °C to +1 °C. Conversely, for normothermic infants, the mean difference was smaller at 0.1 °C, with a narrower limit of agreement from -0.4 °C to +0.6 °C.
UNASSIGNED: While there is a good correlation between axillary and rectal temperatures, the wider limits of agreement indicate variability, particularly in hypothermic infants. For a more accurate assessment of core body temperature in hypothermic infants, clinicians should consider using rectal measurements to ensure effective thermal regulation and better clinical outcomes.

摘要：
■这项研究的目的是在新生儿重症监护病房（NICU）入院时使用数字温度计评估出生不到32周的早产儿的直肠和腋窝温度测量值之间的差异。
■预期，观察,单中心研究。使用数字温度计进行直肠和腋窝温度测量。该研究检查了各种孕产妇和新生儿因素来描述研究组，包括使用产前皮质类固醇,母亲糖尿病和高血压的发生，产妇长期胎膜破裂（PROM）的历史，母体绒毛膜羊膜炎,交付方式，随着新生儿的性别，出生体重,和胎龄。计算皮尔逊相关系数（R）以确定直肠和腋窝部位的温度之间的线性关系。使用Bland-Altman方法分析两组温度数据之间的一致性。
■80名平均胎龄为28.4周(SD=2.9)、平均出生体重为1,229g(SD=456)的婴儿被纳入研究。平均腋窝温度为36.4°C（SD=0.7），低于平均直肠温度36.6°C（SD=0.6）（p=0.012）。在59％的情况下，直肠温度超过了腋窝测量值，而在21%的病例中观察到相反的情况。直肠和腋窝温度具有很强的相关性（皮尔逊相关系数为0.915，p<0.001）。Bland-Altman图显示，两次温度测量之间的平均差为0.1C，但一致的界限很宽（0.7至-0.6°C）。对于低体温的婴儿，直肠和腋窝温度之间的平均差为0.27°C，在-0.5°C至+1°C的范围内具有广泛的一致性。相反，对于体温正常的婴儿，在0.1°C时，平均差较小，从-0.4°C到+0.6°C的更窄的协议极限。
■虽然腋窝和直肠温度之间有很好的相关性，更广泛的协议限制表明可变性，特别是低体温的婴儿。为了更准确地评估低体温婴儿的核心体温，临床医生应考虑使用直肠测量,以确保有效的热调节和更好的临床结果.
