[Blood pressure measurement with Doppler in normal newborn infants and infants]
Insights
This study measured systolic blood pressure in 251 Chilean children using the Doppler method. Results show higher blood pressure values compared to traditional sphygmomanometry, especially in infants.
Area of Science:
- Pediatrics
- Cardiovascular Health
- Biomedical Engineering
Context:
- Establishing normative blood pressure values is crucial for pediatric health monitoring.
- The Doppler method offers a non-invasive approach to cardiovascular assessment in children.
- Previous studies may not fully capture the nuances of blood pressure in diverse pediatric populations.
Purpose:
- To determine systolic blood pressure (SBP) percentiles in healthy Chilean children aged 0-24 months using the Doppler method.
- To compare SBP values obtained via Doppler with those from sphygmomanometry in a matched pediatric cohort.
- To investigate age-related variations in SBP within the first two years of life.
Summary:
- Systolic blood pressure was measured in 251 healthy children (0-24 months) from Santiago, Chile, using the Doppler method.
- Significant dispersion of SBP was observed in newborns (85-125 mmHg), with narrower ranges in older infants.
- Fifty and 95 percentiles for SBP varied across age groups, generally increasing with age.
- Doppler-derived SBP values were higher than those measured by sphygmomanometry in a comparable group.
Impact:
- Provides updated, method-specific reference ranges for pediatric systolic blood pressure in a South American population.
- Highlights potential discrepancies between Doppler and sphygmomanometry, informing clinical practice and future research.
- Contributes to a better understanding of normal cardiovascular development in infancy and early childhood.
Abstract:
Systolic blood pressure (SBP) was measured by Doppler method in an aleatory sample of 251 healthy children from south-east Santiago Chile (131 females and 120 males) which were divided by age in five groups: 0 to 28 days (n = 5) 1 to 5 months (n = 48), 6 to 11 months (n = 48), 12 to 17 months (n = 46) and 18 to 24 months (n = 45). Great dispersion of SBP values occurred among newborn infants (range 85 to 125) in comparison with groups 1 to 5 months (105 to 130), 6 to 11 months (118 to 130). Fifty and 95 percentiles were, respectively, 107 to 125; 116 to 130; 121 to 130; 118 to 130 and 120 to 130. These values were greater than those obtained by sphygmomanometry in a similar matched group of children.
