Percutaneous oxygen delivery to the preterm infant
1Department of Neonatal Medicine and Surgery, City Hospital, Nottingham.
Insights
Transdermal oxygen therapy can supplement oxygen delivery for preterm infants with respiratory distress. This method showed increased arterial oxygen levels, particularly in less mature infants.
Area of Science:
- Neonatal Medicine
- Respiratory Physiology
- Dermatology
Background:
- Preterm infants often experience severe respiratory distress.
- Pulmonary gas exchange can be compromised in premature neonates.
- Current oxygen delivery methods may have limitations.
Purpose of the Study:
- To investigate the feasibility of percutaneous oxygen delivery in preterm infants.
- To assess the efficacy of transdermal oxygen absorption in supplementing oxygenation.
- To determine factors influencing oxygen absorption through the skin.
Main Methods:
- Studied 13 preterm infants (25-31 weeks gestation) requiring ventilation for respiratory distress.
- Measured changes in arterial oxygen tension following increased ambient oxygen concentration.
- Correlated oxygen absorption with infant maturity and epidermal barrier integrity.
Main Results:
- Percutaneous oxygen absorption increased arterial oxygen tension by 4.5 to 13.8 mm Hg (mean 8.9 mm Hg).
- The effect was more pronounced in less mature infants.
- Infants with weaker epidermal barriers showed greater transdermal oxygen uptake.
Conclusions:
- Transdermal oxygen therapy is a feasible method for delivering oxygen to preterm infants.
- This approach can usefully supplement oxygen delivery in neonates with poor pulmonary gas exchange.
- The efficacy of transdermal oxygen is influenced by gestational age and skin condition.
Abstract:
The feasibility of delivering therapeutically useful amounts of oxygen percutaneously was investigated in 13 preterm infants. Their gestation ranged from 25 to 31 weeks and all were being ventilated for severe respiratory distress. Raising the ambient oxygen concentration resulted in an increase in arterial oxygen tension of 4.5 to 13.8 mm Hg (mean 8.9 mm Hg) as a result of percutaneous oxygen absorption. The change was greatest in the least mature infants and in those with the weakest epidermal barrier. Transdermal oxygen therapy can usefully supplement oxygen delivery to very premature infants with poor pulmonary gas exchange.
