目的：探索重度颅脑损伤、脑出血等需要长时间留置导尿患者更换导尿管的最佳间隔时间，以减轻患者痛苦，降低尿路感染发生率。方法：将留置导尿时间超过5周的病人作为研究对象，随机分为A组、B组和C组，其中A组每3周更换一次导尿管，B组每4周更换一次导尿管，C组每5周更换一次，3组患者分别于第1、7、14、21、28天和第35天留取中段尿做细菌培养检查，并将更换后的导尿管前端进行细菌培养检查，找出更换导尿管的最佳间隔时间。结果：3组患者尿液及导尿管前端细菌培养阳性率比较差异均无统计学意义。结论：重度颅脑损伤、脑出血等长期留置导尿管患者每5周更换一次导尿管是切实可行的。

Objective:To investigate the optimal intervals for replacement of the indwelling urinary catheter for long-term bladder drainage in patents with severe traumatic brain injury or cerebral hemorrhage in order to reduce their sufferings and incidence of urinary tract infection .Methods:Eligible subjects consisted of those requiring use of the indwelling urinary catheter over five weeks ,and randomly allocated to group A ( catheter replacement once every 3 weeks),group B(replacement of the catheter once every 4 weeks) and group C(catheter replacement once every 5 weeks).Specimens were collected from the midstream urine and at the tip of the catheter at day 1,7,14,21,28 and 35,respectively in the three groups,for bacterial culture in order to determine the optimal intervals for the catheter replacement .Results:Positive culture showed no significant difference among the groups regarding either the speci-mens from midstream urine or at the tip of the catheter .Conclusion:Indwelling urinary catheter can be replaced once every 5 weeks for patients with severe traumatic brain injury or cerebral hemorrhage requiring long-term bladder drainage.
