The objective of this study is to assess the diagnostic accuracy of a novel hypothermia monitoring and alert bracelet device (BEMPU Bracelet) in low birth weight (LBW) neonates weighing less than 2000 g.
This was a controlled prospective study.
This study was done in the step-down nursery of a tertiary level newborn unit of a major teaching hospital in India.
Eligible cases fulfilling inclusion criteria were given BEMPU Bracelets for a period of 24 h. A comparison was made between skin temperatures taken at the axilla by a mercury thermometer and skin temperatures taken at the wrist by the BEMPU Bracelet. Temperatures were taken every 6 h and every time the BEMPU Bracelet alarmed. Trained nurses obtained temperature measurements on newborns during their 24-h stay in the hospital step-down nursery.
A total of 461 neonates were screened for hypothermia, giving 2428 temperature readings. Three hundred and eleven of 461 babies experienced hypothermia at some point. The 461 babies studied experienced 495 episodes of hypothermia in total. The sensitivity and the specificity of the bracelet in diagnosing hypothermia were 98.6% and 95% respectively. The positive and negative predictive values of the bracelet were 83.6% and 99.6%, respectively. The accuracy of the bracelet in diagnosing hypothermia was 95.8%.
The BEMPU Bracelet is an accurate screening tool to detect and alert for neonatal hypothermia, thereby facilitating prompt management, which could prevent complications.
本研究的目的是评估一种新型低温监测与警报手环设备（BEMPU手环）对体重小于2000克的低出生体重（LBW）新生儿的诊断准确性。
这是一项对照前瞻性研究。
本研究在印度一家主要教学医院三级新生儿病房的降阶梯病房进行。
符合纳入标准的合格病例佩戴BEMPU手环24小时。将水银温度计测量腋窝处的皮肤温度与BEMPU手环测量手腕处的皮肤温度进行比较。每6小时测量一次温度，每次BEMPU手环发出警报时也进行测量。经过培训的护士在新生儿入住医院降阶梯病房的24小时内对其进行体温测量。
共筛查了461例新生儿是否体温过低，获得了2428次体温读数。461例婴儿中有311例在某些时候出现体温过低。所研究的461例婴儿总共经历了495次体温过低发作。该手环诊断体温过低的敏感性和特异性分别为98.6%和95%。该手环的阳性预测值和阴性预测值分别为83.6%和99.6%。该手环诊断体温过低的准确性为95.8%。
BEMPU手环是一种准确的筛查工具，可检测并警示新生儿体温过低，从而便于及时处理，预防并发症。
