本研究對87位需做餘尿量評估的復健病人，在排尿後以膀胱超音波BVI 3000機型測量掃描餘尿量，然後接著給予間歇導尿，以repeat measures ANOVA分析，結果發現膀胱超音波及導尿測量所得尿量是無差異(F=0.38 p=.68)，再以性別、診斷、姿勢、腹部脂肪厚度、膀胱形狀、尿量、操作間隔時間等因素做分析，以repeat measures ANOVA檢定亦無差異，同時測量兩種測量方法所花費護理時數：膀胱超音波平均為45±18秒(range: 17-119秒)，導尿為平均280±106秒(range: 136-664秒)，結論是膀胱超音波與導尿方式對餘尿量的測量一樣好，膀胱超音波與導尿時間相差約3-8倍的護理時數，先以超音波來測量餘尿量可以減少不必要的導尿次數及節省醫療人力成本。 The purpose of this study was to examine the difference between using bladder scan and catheterization on 87 rehabilitation patients to evaluation the amount of residual urine. After voiding, each subject was scanned with a BladderScan BVI 3000, then catheterized for postvoid residual urine volume (PVR). Repeat measure ANOVA analysis showed that the factors of gender, diagnosis, posture, the thickness of abdominal fat, bladder shape, the amount of urine, and the interval of operation time have no difference in this study. It takes 45 ± 18 seconds (range: 17-119) to accomplish a bladder scan, and it takes 280 ±106 seconds (range: 136-664) for nursing staff to complete a catheterization for patient. However, the catheterization process takes nursing staff 3-8 times longer then operating a bladder scan. This would diminish unnecessary catheterization and save on medical staff resources.
