不同膀胱冲洗频率对长期留置导尿管患者尿路感染及细菌定植的影响分析
Effect of different bladder irrigation frequency on urinary tract infections and bacterial colonization of patients with catheterization
摘要
Abstract
Objective To investigate the effect of different bladder irrigation frequency on urinary tract infec‐tions and bacterial colonization of patients with catheterization .Methods A total of 275 patients with long‐term in‐dwelling catheterization were recruited in this study ,and divided into group A ,B ,C ,D randomly .All patients were carried out bladder irrigation in the same manner ,group A (n=67) with flushing frequency 2 times a day ,group B (n=69) with 1 times a day ,group C (n=70) with 2 times per week ,group D (n=69) without flushing .The inci‐dence of urinary tract infections after placing the catheter 3 ,7 ,14 ,21 d of the four groups were recorded ,after placing the catheter 21 d ,isolation and culture of bacteria from midstream urine were conducted ,the number of colonies were recoded .Results The incidence of urinary tract infections in group A after placing the catheter 3 ,7 ,14 ,21 d were 2 .99% ,10 .45% ,16 .42% and 35 .82% ,those of group B were 0 .00% ,10 .14% ,20 .29% and 33 .33% ,those of group C were 0 .00% ,2 .86% ,10 .00% and 17 .14% ,those of group D were 0 .00% ,10 .14 % ,23 .19% and 40 .58% . The infection rate of four groups after treating 3 d had no statistical difference (P> 0 .05);The infection rate in group C after treating 7 ,14 ,21 d was significant lower than other groups ,while those of the group D were significant higher than other groups ,the differences were statistical significant (P<0 .05) .The pathogens colonies of Escherichia coli ,Proteus ,Klebsiella ,Streptococcus faecalis and other pathogens were (9 .38 ± 0 .87) ,(6 .33 ± 0 .54) ,(4 .97 ± 0 .38) ,(2 .12 ± 0 .24) and (0 .92 ± 0 .06) ,which were significant less than the other three groups(P<0 .05) .Conclu‐sion The bladder irrigation could effectively reduce the incidence rate of urinary tract infection of patients with long‐term indwelling catheterization ,but frequent washing isn′t good ,the frequency of bladder irrigation as twice a week is appropriate .关键词
