[Study on blood pressure standard in children using the automatic sphygmomanometer].
In Japan, two treatment guidelines exist for pediatric patients with hypertension. The Guidelines for Drug Therapy in Pediatric Patients with Cardiovascular Diseases (JCS2012), by the Japanese Circulation Society, cite the stethoscopy-based American guidelines. The Guidelines for the Management of Hypertension (JSH2009), by the Japanese Society of Hypertension, focus on Japanese data obtained from automated sphygmomanometry. The frequent use of automated sphygmomanometers in clinical practice implies that the JSH2009 guidelines might be better; however with strict low reference values for the diastolic phase, overtreatment may result. Only the Japanese Circulation Society's guidelines include a therapeutic strategy, and the Chronic Kidney Disease (CKD) Guide, CKD Guidelines, and school urinary screening tests all cite these guidelines on stethoscopy-based blood pressure determination. Stethoscopy should be conducted during a medical examination; however, due to limited time in clinical practice, most physicians use automated sphygmomanometers while nevertheless relying on the Japanese Circulation Society reference values--which are stethoscopy-based. To find a compromise, we compared reference values in Japan with those from South Korea (automated sphygmomanometer-based) and those from the United States (stethoscopy-based). Moreover, we examined the results of recent accuracy tests for automated sphygmomanometers. Although the JSH2009 reference values for the systolic phase were consistent with those in the United States (stethoscopy-based), the reference values for the diastolic phase were lower. We observed the same tendency when comparing JSH2009 reference values with those in South Korea (automated sphygmomanometer-based). Conversely, there were only small differences between automated sphygmomanometry and mercury measurement, and we found it was possible to substitute the values from automated sphygmomanometry for stethoscopy. A large-scale study that takes into account patient height, measurement method, and treatment criteria is required to establish appropriate reference values. Even if automated sphygmomanometry is used until appropriate values are established, we consider the criteria provided in the American guidelines as appropriate.
