Body temperature is an important vital sign in clinical practice which can be measured via electronic contact thermometers and infrared non-contact thermometers.
To compare temperature readings taken by non contact infrared thermometer with the conventional digital axillary, rectal and oral temperature readings as well as the influence of environmental temperature on noncontact infrared thermometer readings.
A prospective study carried out in the Paediatric outpatient clinic of the Rivers State University Teaching Hospital, Nigeria from September 2020 to December 2020. Infrared noncontact forehead and jugular temperatures along with contact axillary, oral and rectal temperatures at a recorded atmospheric temperature and pressure were measured. Data collected was analysed.
A total of 247 children aged 1month to 16 years were enrolled, the mean differences of the temperature pairs of contact and non-contact thermometry ranged from 0.45 - 0.77°C (1.64, -1.81°C) 95% LoA. The highest mean difference was found between infrared forehead and axillary [MD; 0.45(1.64,-0.73°C) 95%LoA] temperatures. There was a significant positive correlation between the mean difference of infrared forehead/ rectal temperature and atmospheric temperature (r = 0 .211 p = 0.029). Linear regression model showed that infrared forehead temperature of 37.1°C was equivalent to rectal temperature of 38°C and axillary of 37.4°C which is the standard cut off for fever. Infrared jugular of 37.2°C was equivalent to rectal of 38°C and axillary temperature of 37.4°C was equivalent to infrared jugular of 37.03°C all at a mean atmospheric temperature of 28.3±1.8°C.
The mean difference by which infrared noncontact thermometry predicts core temperatures may differ based on atmospheric temperature. Infrared non-contact forehead thermometer reading of 37.1°C could be considered as the fever cut off for non-contact forehead thermometry in Nigeria in regions where the mean atmospheric temperature is 28.3±1.8°C.
体温是临床实践中的一个重要生命体征,可以通过电子接触式温度计和红外非接触式温度计进行测量。
比较非接触式红外温度计与传统的数字腋窝、直肠和口腔温度读数的差异,以及环境温度对非接触式红外温度计读数的影响。
这是一项在 2020 年 9 月至 2020 年 12 月期间在尼日利亚河流州立大学教学医院儿科门诊进行的前瞻性研究。测量了记录大气温度和压力下的红外非接触式额温和颈内温度以及接触式腋窝、口腔和直肠温度。收集的数据进行了分析。
共纳入 247 名 1 个月至 16 岁的儿童,接触式和非接触式测温的温度差值平均范围为 0.45-0.77°C(1.64,-1.81°C)95%可信区间。红外额温与腋温差值最大[MD;0.45(1.64,-0.73°C)95%可信区间]。红外额温/直肠温度的平均差值与大气温度呈显著正相关(r=0.211,p=0.029)。线性回归模型显示,红外额温 37.1°C 相当于直肠温度 38°C,腋温 37.4°C,这是发热的标准临界值。在平均大气温度为 28.3±1.8°C 时,红外颈内温度 37.2°C 相当于直肠温度 38°C,腋温 37.4°C 相当于红外颈内温度 37.03°C。
红外非接触式测温预测核心温度的平均差值可能因大气温度而异。在平均大气温度为 28.3±1.8°C 的尼日利亚地区,红外非接触式额温计读数 37.1°C 可作为非接触式额温计发热的临界值。
