Abstract:
Objective: To explore how the timing of the initial dressing change influences bacterial growth when alginate dressings were used after peripherally inserted central catheter (PICC) line insertion in tumor patients.
Methods: In total, 186 tumor patients who had an alginate dressing after PICC insertion were randomly divided into a control group, observation group one (OG1), and observation group two (OG2). The control group had their first dressing change 48 h after PICC insertion, while OG1 was after 72 h and OG2 was after 96 h after. Samples were taken at the dressing change from the insertion site and surrounding skin. The results of the bacterial culture were compared to investigate how the timing of the first dressing change affected catheter infection.
Results: Of the 186 patients, 29 had a positive bacterial culture. Of these, 10 were in the control group, 9 were in OG1, and 10 were in OG2. IBM SPSS Statistics 21.0 was adopted to analyze the correlation between the timing of the first dressing change and insertion site infection. No statistical significance between the timing of the first dressing change and insertion site infections was found (P > 0.05).
Conclusions: The condition of each tumor patient should be comprehensively evaluated after PICC placement to determine when the first dressing change should occur, but it can likely be extended to 96 h after insertion to promote wound healing, reduce clinical workload, and lower patient economic burden.
