A premeasurement period of 5 minutes quiet resting is recommended prior to measuring blood pressure. The aim of this study was to determine the effect of this period of rest on the level of blood pressure in pregnant women. One hundred pregnant women had their blood pressure measured on a single visit using a QuietTrak ambulatory blood pressure monitor, used to remove human observer bias. Group 1 (n = 50) had blood pressure measured as soon as possible on entering the clinic room and again after 5 minutes rest. Group 2 were rested for 5 minutes on entry to the clinic room prior to the first blood pressure measurement and had the second measurement taken after a further 5 minutes rest. Results were compared in the 2 groups using ANOVA. In Group 1, the initial, mean systolic blood pressure was 116.6 versus 115.5 mmHg taken after 5 minutes quiet rest (p = 0.66). The corresponding diastolic values were 66.2 versus 64.1 (p = 0.40). In Group 2, the initial mean systolic blood pressure was 116.2 versus 115.6 taken after 5 minutes quiet rest (p = 0.85). The corresponding diastolic values were 68.5 versus 65.6 (p = 0.34). Blood pressure was as likely to rise as to fall after a period of quiet rest. It is not necessary to have pregnant women quietly resting during routine visits before having blood pressure measured.
建议在测量血压前进行5分钟的安静休息预测量期。本研究的目的是确定这段休息时间对孕妇血压水平的影响。100名孕妇在单次就诊时使用QuietTrak动态血压监测仪测量血压，该监测仪用于消除人为观察者偏差。第1组（n = 50）进入诊室后尽快测量血压，5分钟休息后再次测量。第2组在首次测量血压前进入诊室休息5分钟，再休息5分钟后进行第二次测量。使用方差分析比较两组结果。在第1组中，初始平均收缩压为116.6 mmHg，安静休息5分钟后为115.5 mmHg（p = 0.66）。相应的舒张压值分别为66.2和64.1（p = 0.40）。在第2组中，初始平均收缩压为116.2 mmHg，安静休息5分钟后为115.6 mmHg（p = 0.85）。相应的舒张压值分别为68.5和65.6（p = 0.34）。安静休息一段时间后，血压升高和降低的可能性相同。在常规就诊时测量血压前，没有必要让孕妇安静休息。
