For this research we have used the world health organization who guidelines 1997 for temperature range which is between 365c and 375c. Temperatures measured at the four sites agreed closely in this group of largely.

Measurement of core body temperature in preterm infants. Foot temperature means ranged from 353c to 371c. The target body temperature was set at 368c as recommended by. Body temperatures of 99 term and 44 preterm infants were measured at four sites. Body temperature is commonly measured to confirm the presence or absence of fever. Serial assessments of body composition in preterm infants at 32 and 36 weeks postmenstrual age show consistent increments in body fat up to 3 months of corrected age. Temperature measurements were performed simultaneously within 2 minutes for each infant using three methods.
The shielded abdominal skin temperature is known to correlate with the core body temperature due to near zero heat flux 12 13. And 3 rectal temperature t r using a soft flexible vinyl covered thermistor probe model ew 08432 00 cole parmer. What constitutes normal temperature in preterm and term infants is still unclear resulting in a wide range of temperatures being accepted as normal. 2 axillary temperature tax using a digital electronic thermometer model mds9656 medline industries mundelein il. Temperatures measured at the four sites agreed closely in this group of largely normothermic infants. Mean daily abdominal temperatures for the four infants ranged from 351c to 369c.

The who recognises maintaining an appropriate body temperature as a primary principle of newborn care and recommends thermal protection for all infants with special attention for infants who are premature or small for their gestational age for example 25 kg at birth or born before 37 weeks gestation and also recommends frequent measurements from every hour in a seriously ill baby to two to four times per day in a small or very small baby and once daily in an infant progressing well. Core temperature is generally defined as the temperature measured within the pulmonary artery. Hand temperature was very close to foot temperature in each infant with means ranging from 358c to 368c. Infant prematurephysiology monitoring physiologicmethods.
1 temporal artery temperature t ta using an infrared temporal artery thermometer model tat 5000 exergen corporation watertown ma. Core 5 cm beyond the anus with an electronic telethermometer rectum 2 cm with a mercury in glass thermometer axilla and between the skin and mattress. Transcutaneous thermometry is reliable for monitoring core body temperature as indicated by rectal temperature in stable preterm infants in a convective incubator. Body temperatures of 99 term and 44 preterm infants were measured at four sites. However there remains considerable controversy regarding the most appropriate thermometer and the best anatomical site for temperature measurement.
