We assessed the sensitivity, specificity and likelihood ratio of a low cost liquid crystal strip thermometer (LCT) compared with axillary mercury thermometry for the detection of neonatal hypothermia in Nepal. The subjects were 76 healthy newborns in the government maternity hospital of Kathmandu, Nepal in winter. The validity of LCT for the detection of neonatal hypothermia (less than 36 degrees C) showed a sensitivity of 83 per cent, specificity 96 per cent, positive predictive value 98 per cent and a likelihood ratio of 23. Use of LCT on newborns in this setting raises a measured pretest probability of first day hypothermia of 63 per cent to a post-test probability of 97 per cent. Liquid crystal thermometry is a simple, low-cost, and valid method for identifying core hypothermia in newborns. It is ideal for isolated rural communities where LCT strips could be added to delivery kits.
我们评估了一种低成本液晶条式体温计（LCT）与腋温汞柱体温计相比，用于检测尼泊尔新生儿体温过低的敏感性、特异性和似然比。研究对象为冬季在尼泊尔加德满都政府妇产医院的76名健康新生儿。LCT检测新生儿体温过低（低于36摄氏度）的有效性显示，敏感性为83%，特异性为96%，阳性预测值为98%，似然比为23。在此环境下对新生儿使用LCT，可将首日体温过低的测量前验概率从63%提高到验后概率97%。液晶体温计是一种简单、低成本且有效的识别新生儿核心体温过低的方法。对于孤立的农村社区而言非常理想，在这些社区，LCT试纸条可添加到分娩包中。
