加護病房兩種血壓測量方法之相關研究

Relevant Research of Two Blood Pressure Measuring Methods in Intensive Care Unit

本研究旨在調查侵入性動脈血壓直接法和自動非侵入性間接血壓間接法測量所得的血壓值之間的相關性。研究樣本取自於南部某醫學中心加護病房已放置侵入性動脈導管，而且手臂能測量非侵入性間接血壓值的患者，共收案位病患，每位病患最多測量次，最少測量次，共測得人次血壓值。本研究六位測量員先進行前趨研究測試，取得測量員間一致性達。資料分析以建檔，再以軟體版進行描述性分析，並運用統計軟體之進行重複測量分析，比較直接法與間接法的相關性及相關性之強弱。研究結果顯示：侵入性動脈血壓和自動非侵入性間接血壓測量所得的血壓值具有顯著相關；即非侵入性間接收縮壓、舒張壓、平均血壓分別為歸零前侵入性動脈收縮壓、舒張壓、平均血壓之＋、＋、＋。非侵入性間接收縮壓、舒張壓、平均血壓分別為歸零後侵入性動脈收縮壓、舒張壓、平均血壓之＋、－、＋。故建議對於已放置侵入性動脈導管的病患，即可直接採用侵入性動脈血壓測量值來監測及處置病人的病情變化，不需同時測量兩種血壓值。關

The purpose of this study was to investigate the relevance between the invasivearterial pressure measurement value and noninvasive blood pressure measurementvalue. A total of 1,186 blood pressure values from 144 patients were obtained. Thestatistical procedures applied in data management (by Excel) were descriptive statisticsfrom EPI-INFO (6.01 edition). Repeat measurement analysis used GeneralizedEstimating Equations(GEE). The result indicated that there was significant relevancebetween these two kinds of blood pressure measuring methods. It indicated that thesystolic, diastolic and mean blood pressure value of noninvasive blood pressurewere equal to the systolic, diastolic and mean blood pressure value of invasive arterialpressure's 62 percent+ 31.6; 78.3 percent + 0.72; 70.6 percent + 8.8 before the monitorof invasive arterial pressure returned to zero. We therefore suggest that patientswho already set the invasive arterial pressure line do not need to measure two kindsof blood pressure at the same time.
