輪班制護理人員血壓之研究

本研究由十三位21至25歲，工作於心臟科加護病房的女性護理人員組成 (平均年齡23.2 +/- 1.52歲)，研究輪班制工作對於24小時血壓韻律的影響。使用Dyna Pulse 5000A記錄連續在白班工作 (08:00~16:00) 兩個月之後的護理人員24小時血壓資料，相同的護理人員在轉換至大夜班 (00:00~08:00) 工作7~14天之後進行第二次的血壓資料記錄。結果顯示：轉換至大夜班之後，全日平均收縮壓較高( 白班 112.08 +/- 14.27 mmHg ; 夜班 115.94 +/- 15.04 mmHg, P=0.004)，舒張壓與心跳在日夜間的數值差異消失，心跳的日夜波動未沉降現象由15.4% 增加至 92.3%。本研究顯示加護病房護理人員的輪班制工作與日夜波動平坦化及24小時平均血壓上升相關。

13 normotensive female nurses aged between 21 y/o and 25 y/o (mean 23.2 +/- 1.52y/o) worked in cardiac intensive care unit comprised the subjects of this study to determine the relationship between shift schedule working and 24 hrs blood pressure rhythm. 24 hrs ambulatory blood pressure data obtained using Dyna Pulse 5000A when they worked in day-shift schedule (08:00~16:00) for more than 2 months, the second data of the same subjects obtained after they shift to night-shift schedule (00:00~08:00) working for 7~14 days. The results shown significant higher 24 hrs mean systolic blood pressure ( day-shift = 112.08 +/- 14.27 mmHg to night shift = 115.94 +/- 15.04 mmHg, P=0.004); loss of the difference of DBP and HR between awake and sleep period ; significant increased in the percentage of non-dipper in HR (day-shift 15.4% to night-shift 92.3%) after shift to night-shift schedule. This study shown shift schedule work of intensive care givers was associated with flattened circadian change of blood pressure and higher mean 24 hr blood pressure.
