RESUMO
Objective To evaluate the effects on catheter related blood stream infection by different dressing frequency of peripherally inserted central catheter(PICC)with neonates. Methods A systematic review of randomized controlled trials (RCTs) from databases, Data were searched about the transparent dressing replacement frequency for neonatal PICC catheterization. The meta-analysis was performed by using RevMan 5.2 software. Results Nine RCTs were included in a total of 1 730 patients. Meta analysis showed that there was no significant difference in the incidence of PICC puncture dressing, catheter-related infections (including puncture port infection, catheter-related blood flow infection, catheter bacterial colonization) at every 3, 5, and 7 days (P> 0.05). Conclusion the dressing of PICC catheter are replaced will not increase the incidence of catheter-related infections within 7 days, throughout the more appropriate frequency of dressing replacement is once every 7 days.
