In current clinical practice, the mercury sphygmomanometer (MS) is being replaced by alternatives as aneroid sphygmomanometer and semiautomatic and automatic-type digital sphygmomanometers (DS). However, a validated DS in adults may not be appropriate for use in the pediatric population, particularly for wrist-type devices. A pilot study was conducted to determine if wrist DS can replace the MS for clinical use in children population. Measuring blood pressure for pediatric patients with wrist diameter greater 13.5 cm was made. The correlation between wrist DS and mercurial device was evaluated and compared by Bland-Altman. The flexible-bracelet wrist DS (CH-656C) showed discrepancies in the mean ± standard deviation differences from 2.6 ± 5.5 to 5.8 ± 6.2 mmHg compared to the mercury device, while the rigid-wrist DS (CH-607) showed variations from 3.9 ± 5.2 to 11.4 ± 7.6 mmHg compared to the MS. For some cases, the agreement was not presented because the results are above the criteria of the American Association for Advancement Medical Instrumentation. This study revealed that the discrepancy of the results is so high for both digital devices, which makes it impossible suggest that any of them can replace the MS. Therefore, it is recommended that hospitals should ensure validation in the pediatric population before the wrist DS is used, particularly when it is utilized for diagnosis in children under 11 years. |
