OBJECTIVE
To assess the accuracy of the OMRON-MIT (inflationary) and OMRON-M7 (deflationary) devices for measuring blood pressure in a pregnant population, including women with preeclampsia, according to the British Hypertension Society protocol.
METHODS
Forty-five pregnant women, including 15 with preeclampsia, were recruited at a large teaching hospital. Nine sequential same arm measurements were taken from each patient alternating between the test device and mercury sphygmomanometry. Both devices were assessed in the same women. Data were analysed according to the British Hypertension Society protocol.
RESULTS
The OMRON-MIT achieved an A/A grade in both pregnancy and preeclampsia with an overall mean difference (SD) of -1.3 (5.6) mmHg and 0.4 (5.6) mmHg for systolic and diastolic pressures, respectively. The OMRON-M7 achieved an A/A grade in pregnancy and a B/B grade in preeclampsia with an overall mean difference (SD) of -5.3 (6.6) mmHg and -3.5 (6.9) mmHg.
CONCLUSION
Both the OMRON-MIT and the OMRON-M7 can be recommended for use in pregnancy and preeclampsia. Inflationary oscillometry (OMRON-MIT) was more accurate in preeclampsia.
目的
根据英国高血压学会的方案，评估欧姆龙MIT（充气式）和欧姆龙M7（放气式）设备在测量孕妇（包括子痫前期女性）血压方面的准确性。
方法
在一家大型教学医院招募了45名孕妇，其中15名患有子痫前期。对每位患者的同一侧手臂进行9次连续测量，在测试设备和汞柱式血压计之间交替进行。两种设备均在同一批女性中进行评估。数据根据英国高血压学会的方案进行分析。
结果
欧姆龙MIT在妊娠和子痫前期均达到A/A级，收缩压和舒张压的总体平均差异（标准差）分别为-1.3（5.6）mmHg和0.4（5.6）mmHg。欧姆龙M7在妊娠中达到A/A级，在子痫前期达到B/B级，总体平均差异（标准差）分别为-5.3（6.6）mmHg和-3.5（6.9）mmHg。
结论
欧姆龙MIT和欧姆龙M7均可推荐用于妊娠和子痫前期的血压测量。充气式示波法（欧姆龙MIT）在子痫前期中更准确。
