ABSTRACT
Aim
To   compare    different   available   modes   (forehead   infrared  thermometer   ,axillary  temperature  by  thermister  probe and  digital  thermometer,  with   axillary  temperature  by  gold  standard  mercury  thermometer)  of  temperature  measurement  in  neonatal  hypothermia  in  order  to  come  out  with  most  accurate  one  among  them.
Background
Hypothermia is very important in essential newborn care as it can lead to mild to severe life threatening complication, so detecting hypothermia takes important role in its management.
Material Methods
Study  Design:  Setting  was   Neonatal  Intensive  Care  Unit (Level 3),   Kamla  Raja  Hospital  ,Gajra  Raja  Medical  College,  Gwalior,  India.  A  Prospective  study  of  one  year  (July  2010  -  June  2011 )  duration   done   with  1690  admissions   of  neonatal  intensive  care  unit  (full  fill  inclusion  criterion )   by applying   Fisher  test  on  2×2  contingency  table  to  get   sensitivity , specificity , positive  predictive  value , negative  predictive  value  and  accuracy  of  above  4  methods   by  STATA  9.1 (STATA  corporation,  college  station  ,  TX,  USA).
Results
Digital  thermometer  is  having  highest  sensitivity  (99.1%),  specificity   (98.1%),  positive  predictive  value  (97.4%)  and  negative  predictive  value(99.3%).
Conclusion
Digital axillary thermometry is the best alternative to mercury thermometer for measuring neonatal temperature compared with axillary temperature by thermister probe and forehead temperature by infrared thermometer.
KEY WORDS
Neonatal temperature recording, Digital thermometer,   Forehead infrared   thermometer, mercury thermometer, Thermister probe.
