BACKGROUND:Auscultatory mercury sphygmomanometers to measure blood pressure (BP) have been banned from health services because of risk of pollution and environmental accidents with mercury. Aneroid appliances could be an alternative. OBJECTIVE:To validate the Missouri aneroid device for blood pressure measurement in cancer patients according to the protocol of the European Society of Hypertension (ESH). METHODS:33 patients hospitalized or under outpatient care at the Cancer Institute of the State of São Paulo, FMUSP, were evaluated. Three trained and blinded observers performed nine sequential blood pressure measurements interspersed with the mercury sphygmomanometers. The differences between the values of systolic blood pressure (SBP) and diastolic blood pressure (DBP) of the test device with the mercury sphygmomanometer were classified according to the ESH protocol. RESULTS:The Missouri equipment underwent all three phases required by the ESH Protocol for SBP and DBP, and it was approved in all of the phases. The average difference between the test device and the mercury sphygmomanometer was 0.62 (SD = 4.53) and 0.06 (SD = 6.57) mmHg for SBP and DBP, respectively. No association was found between the differences in BP measurements with sex, age, body mass index and arm circumference and length. CONCLUSION:The results revealed that the aneroid Missouri device meets ESH accuracy recommendations for the measurement of SBP and DBP, and it can be used to replace the mercury sphygmomanometer.

背景:由于汞污染的风险和环境事故的危险,已经禁止在医疗服务部门使用用于测量血压(BP)的听诊水银血压计。无液器具可以替代。
目的:根据欧洲高血压学会(ESH)的协议,验证用于癌症患者血压测量的密苏里州无液装置。
方法:对33名在圣保罗州癌症研究所FMUSP住院或接受门诊治疗的患者进行了评估。三名训练有素且不知情的观察员进行了九次连续的血压测量,并穿插了水银血压计。根据ESH协议对使用水银血压计的测试设备的收缩压(SBP)和舒张压(DBP)值之间的差异进行分类。
结果:密苏里州的设备经历了ESH协议针对SBP和DBP所要求的所有三个阶段,并且在所有阶段都得到了批准。对于SBP和DBP,测试设备与水银血压计之间的平均差分别为0.62(SD = 4.53)和0.06(SD = 6.57)mmHg。在血压测量与性别,年龄,体重指数以及臂围和长度之间的差异之间未发现关联。
结论:结果表明,密苏里州无液装置符合SSH和DBP测量的ESH精度建议,可用于替代水银血压计。
