The Effective Analysis Of Bladder Irrigation For Prevention Against Catheter-associated Infection Of The Spinal Injury Patients

Purpose: To compare and analysis the preventive effects for catheter-associated urinary tract infection by passive bladder irrigation and physical bladder irrigation by encouraged water-intake, so as to bring out a further investigation on the efficiency of bladder irrigation for prevention against catheter-associated urinary tract infection and to direct our clinical nursing management.Method: 83 patients with spinal injury admitted to our hospital from March, 2006 to December, 2006 were studied. At first, the nurses should educate the patients on preventive effects on catheter-associated urinary tract infection of water intake .The patients who would like to increase water intake were selected as control group (physical bladder irrigation); those who refused were selected as contrast group (passive bladder irrigation), within which was further analyzed according to different irrigation flow speed (80~100 drop/min and 120~150 drop/min) and frequency (once/two days and twice/one week). The irrigation of contrast group was started from the second day after catheterization. Nursing of outer urinary tract opening was performed in both control and contrast groups two times one day .Result: Catheter-associated urinary tract infection rate of the patients treated by physical bladder irrigation is 32.43%; catheter-associated urinary tract infection rate of the patients treated by passive bladder irrigation is 63.04%。The occurrences of catheter-associated urinary tract infection in patients treated by physical bladder irrigation were significantly lower than by passive bladder irrigation (p<0.05). The group by irrigation every other day had significantly more infection risk than the group by irrigation twice a week (p<0.05). There was not significantly difference between bladder irrigation at 100drops/min and 200drops/min (p>0.05).Conclusion: For patients with spinal injury who underwent urinary tract catheterization, it showed a more effective method to prevent catheter-associated urinary tract infection by physical bladder irrigation (encouraged massive water-intake) than traditional passive bladder irrigation. The infection risks would be increased with irrigation frequency increase. The irrigation speed of 100drops/min and 200drops/min seemed no difference. So the two methods should be applied flexibly according to individual case to prevent catheter-associated urinary tract infection effectively, relieve the mental and economic burden of the patients, so as to improve the nursing quality.
