The effect of intermittent bladder irrigation on the bacterial counts in urine samples was studied in patients with indwelling catheter and pre-existing urinary tract infection. Four different irrigating solutions were used. Irrigation with saline or 0.25% acetic acid had no effect on the urinary bacterial count. The bacterial counts were effectively reduced during intermittent irrigation both with 0.02% chlorhexidine and with 0.25% silver nitrate. Silver nitrate gave the greatest reduction of bacterial counts but chlorhexidine is preferable due to fewer side effects and greater convenience.
在留置导尿管且已存在尿路感染的患者中，研究了间歇性膀胱冲洗对尿液样本中细菌计数的影响。使用了四种不同的冲洗液。用生理盐水或0.25%醋酸冲洗对尿液细菌计数没有影响。在间歇性冲洗过程中，0.02%氯己定和0.25%硝酸银均能有效降低细菌计数。硝酸银使细菌计数降低幅度最大，但由于副作用较少且更方便，氯己定更可取。
