Pulse Oxygen Saturation Levels and Arterial Oxygen Tension Values in Newborns Receiving Oxygen Therapy in the Neonatal Intensive Care Unit: Is 85% to 93% an Acceptable Range?

Objective. To determine the effect of being in the neonatal intensive care unit (NICU) on pain responses in infants of 32 weeks' postconceptual age (PCA). Design. A cross-sectional comparative design was used. Setting. Two level III NICUs, each in metropolitan, university teaching hospitals. Patients. Infants of 32 weeks' PCA born within the past 4 days (the newly born group; n = 53) were compared with infants of the same PCA who had been born 4 weeks earlier (the earlier-born group; n = 36) and had spent that time in an NICU. Outcome Measures. Heart rate, oxygen saturation levels, and facial actions were used as outcomes in a between-group repeated measures analysis of variance across the heel stick procedure. Background variables of Apgar, weight at birth and data collection, severity of illness, age group, and total number of invasive procedures were entered into a stepwise regression. Results. The two groups responded differently to the heel stick: the earlier-born infants had less behavioral manifestations of pain than the newly born infants. The number of invasive procedures was the primary factor that explained those behavioral differences, with Apgar as a second explanatory factor. The earlier-born infants had higher heart rates and lower oxygen saturation than the newly born infants before as well as during the procedure. These physiological differences were explained by the perinatal factors of age at birth and birth weight. Conclusion. Preterm infants who spend PCA weeks 28 through 32 in an NICU are less mature in their pain response than newborn premature infants of 32 weeks' PCA. Greater frequency of invasive procedures is associated with behavioral immaturity, whereas birth factors are associated with physiological immaturity.

Oxygen Saturation Level

Preterm infants are babies who are delivered before the completion of 37 weeks gestation period. They are born with immature functioning of the brain. In Neonatal Intensive Care Unit (NICU), these infants receives many environmental stimuli, and their comfort will be disturbed. These various sensory stimulus received in NICU influence the functional and neurodevelopmental outcome of these infants and also their quality of life. So this study was intended to evaluate the axillary temperature, heart rate, respiratory rate and oxygen saturation level of these infants prior to nesting and after nesting at the 60th minute. Forty preterm infants who fulfilled the criteria of selection were included in the study by simple random sampling and segregated into case and control groups by blocked randomization. Data was collected and recorded. The temperature was recorded by a digital thermometer, respiratory rate was counted by the number of times the infants' chest rises, heart rate and oxygen saturation readings from the pulse oximeter. The result of the study showed that there was statistically significant effect of nesting at 60th minute, temperature (t=5.03966,p<0.05), respiratory rate(t= -2.13,p<0.05) and heart rate (t=-2.59766,p<0.05). But the effect was not significant on oxygen saturation level (t=1.2,p=0.238). Hence this study result supports the use of nesting in NICU.

Optimal Position

To determine the optimal position for the preterm infant, arterial oxygen tension (Pao2) was monitored in 16 preterm infants by the transcutaneous method with the infants in both supine and prone positions. When the infants were prone, Pao2 rose by a mean of 7.4 mm Hg (P < .001), an increase of 15%. In those infants with residual cardiopulmonary disease, a 25% increase was noted. The higher Pao2 in the prone position was accompanied by a significant decrease in the amount of time the chest wall moved asynchronously. This improved oxygenation in the prone position appears to be the result of enhanced ventilation/ perfusion ratios and not merely secondary to an alteration in sleep state with positioning of the infant. These findings may have important implications in the management of preterm infants requiring neonatal intensive care.
