Meta-analysis of replacement time for long-term indwelling catheter in patients with silicone catheter in China / 现代临床护理

ABSTRACT

ObjectiveTo explore the best time for replacing the long-term indwelling catheter in patients with silicone catheter.MethodsDomestic literature were retrieved and analyzed using Cochrane systematic review,and the meta-analysis of randomized controlled trials was conducted in accordance with inclusion criteria and exclusion criteria so as to look into the most suitable time for replacing the indwelling catheter for patients with silicone catheter at clinical trials.The replacement frequency for the catheters of different size together with the relevant infections in urinary tract infection and relative risk(RR)were used as values for effectiveness of interventions.ResultsA total of 11 literature were retrieved. Meta-analysis results suggested that the RR values of urinary tract infections when the catheters were replaced once every two weeks vs. every four weeks,and once every three weeks vs. every four weeks were 0.51[95% CI(0.40,0.66),P <0.001],0.79[95% CI(0.58,1.08),P = 0.14],respectively.The urinary infection rate of replacing a silicone cathether every 2 weeks was higher than that of every 4 weeks,but there was no difference between that of every 3 weeks and 4 weeks.Conclusion According to the nature of silicone catheter material as well as the clinical indexes, it is most reliable to replace a silicone catheter every four weeks to reach a best clinical outcome.
