| Abstract |
|
To determine the optimal position for the neonatal intensive care, transcutaneous oxygen tension
(TCPO2) was monitored in 20 healthy preterm infants and 20 healthy term infants using the
Radiometer Tc Oxgen Monitor in both supine and prone position. Also, transcutaneous oxygen
tension (TcPO2) was monitored with tilting change in each position.
When the infants were prone, TcPO2 rose by a mean of 7.36 mmHg (p<0.05), an increase of 11%
in the preterm infants and by a mean of 7.7 mmHg (p<0.05), an increase of 12% in the term infants.
And TCPO2 on 20 degree head-up tilt in the prone position was increased by a mean of 3.13 mmHg (p<
0.05) and 4,69 mmHg (p<0.05) in the term infants and the preterm infants respectively. In the supine
position TCPO2 on 20 degree head-up tilt was increased by a mean of 3.07 mmHg (p<0.05) and 4.30
mmHg (p<0,05) in the term infants and the preterm infants respectively. Also, 20 degree head-down
tilts were associated with an equivalent fall in the TcPO2.
These higher TcPO2 were directly associated with an improvement of PaO2 and these improved
oxygenation in the prone poition and head-up tilts appear to be the result of enhanced vetilation-
pefusion ratios and a significant decrease in the amount of time the chest wall moved asynchronously.
These findings may have the important implifications in the neonatal intensive care. |
