The effect of breast- and bottle-feeding on oxygen saturation and body temperature in preterm infants
Insights
Breastfeeding offers significant clinical benefits for preterm infants, including higher oxygen saturation and body temperature. Bottle-feeding may cause more physiological stress, indicated by apnea and oxygen desaturation events.
Area of Science:
- Neonatal care
- Infant nutrition
- Physiological monitoring
Background:
- Preterm infants (<1800 g) require careful nutritional support.
- Assessing the physiological impact of different feeding methods is crucial for neonatal well-being.
Purpose of the Study:
- To compare the clinical effects of breastfeeding versus bottle-feeding in preterm infants.
- To evaluate physiological parameters during different feeding methods.
Main Methods:
- Prospective study of 25 preterm infants (birth weight < 1800 g).
- Continuous monitoring of oxygen saturation, heart rate, respiratory rate, and body temperature during feeding.
- 80 pairs of breast- and bottle-feeding sessions analyzed.
Main Results:
- Significantly higher oxygen saturation and body temperature observed during direct breastfeeding.
- Bottle-feeding was associated with 2 episodes of apnea and 20 episodes of oxygen desaturation.
- No apnea or oxygen desaturation events occurred during breastfeeding.
Conclusions:
- Breastfeeding is a more physiological feeding method for preterm infants.
- Bottle-feeding may induce physiological stress in preterm infants.
- Findings support breastfeeding as a preferred method for preterm infant care.
Abstract:
From July 1997 to June 1998, 25 preterm infants (birth weight < 1800 g) were included in a prospective study to compare the clinical effects of breast- and bottle-feeding. Oxygen saturation, heart rate, respiratory rate, and body temperature were recorded every minute for 20 minutes during feeding periods. Eighty pairs of breast- and bottle-feeding sessions were observed at the chronological age of 9.3 +/- 4.3 (range = 2.1-25.3) weeks. Oxygen saturation and body temperature of the preterm infants were significantly higher when they were directly breastfed. There were 2 episodes of apnea (breath pause more than 20 seconds) and 20 episodes of oxygen desaturation (PaO2 < 90%) during bottle-feeding and none during breastfeeding. We conclude that breastfeeding is a more physiological feeding method for the preterm infant and bottle-feeding may be more stressful.

Assessing Body Temperature - Oral
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...
