Valores de saturación periférica de oxígeno por oximetría de pulso en recién nacidos de término sin patología respiratoria

Abstract

Introduction

Saturation is a basic physiological factor that reflects the delivery of oxygen to the tissues, and has become a crucial tool in neonatology, particularly especially in patients receiving oxygen therapy.

Objective

To obtain the values of peripheral saturation by pulse oximetry in term newborns without respiratory disease and compare them with the term newborns admitted to the Mother and Baby Unit.

Material and methods

An observational, cross-sectional analytical study was carried out on term neonates, born in the National Institute of Perinatology. The pulse oximetry values were taken in the first hours of life, for up to 2 days. The data were processed using the SPSS program, version 13.

Results

No statistically significant differences were found between the oxygen saturation patterns during the day, or between the groups. In the group of newborns admitted to the Minimal Invasion Therapy (MIT) unit, a significant decrease in oxygen levels was observed in the pulse oximetry 5 minutes after starting feedings.

Conclusions

Newborns admitted to the Mother and Baby Unit have less desaturation compared to newborns in the MIT. This may be because they are exclusively breastfed, which promotes better coordination in sucking, swallowing and breathing, a situation that is reflected in the saturation blood levels.
