Effects of increase in body temperature on the breathing pattern in premature infants.

摘要: This study was designed to determine the effects of a mild increase in body temperature within physiological range (0.8 degrees C) healthy premature infants. Seven unsedated infants (38.4 wk +/- 1.5 postconceptional age) were monitored polygraphically during "morning naps" an incubator under two different environmental temperatures: (1) normothermia with set at 25 C and rectal equal 36.9 0.1; (2) hyperthermia 35 37.7 0.15. Respiratory frequency heart rate, respiratory events, i.e., central obstructive apnea, periodic breathing without apneic oscillations tabulated. Results for events expressed as indices total number specific per hour total, quiet active sleep times; duration percentage sleep, times. rate significantly increased by (P less than 0.05). Hyperthermia did not modify or apnea. But 0.05) but sleep. The present shows that enhances instability pattern
