Doppler ultrasonic brachial blood pressure measurements in normal Chinese neonates: a preliminary report.
The purpose of this study was to determine brachial blood pressures in normal Chinese neonates using a Doppler ultrasonic blood pressure monitor (Roche Arteriosonde 1020). The systolic (SP) and diastolic (DP) pressures of 100 healthy, full-term Chinese neonates were determined in triplicate under resting conditions. The pulse pressures (PP) were derived from the SP and DP. Correlation studies reveal significant positive correlation between age and PP (r = 0.34, P less than 0.0002), between weight and SP (r = 0.23, P less than 0.02) and between weight and PP (r = 0.40, P less than 0.02). No significant difference exists between blood pressures of males and females (P greater than 0.05). Comparison with three Western studies reveals that our mean SP is the lowest (1-3). This may be due to technical factors, e.g. different Doppler ultrasonic device, anthropometric factors or true genetic or environmental differences.
