Glucocorticosteroid and Silicone Gel During Patch Application Without Clinical Scar Improvement After Central Venous Catheter Removal: A Randomized Trial.

INTRODUCTION

We studied whether glucocorticosteroid during patch occlusion has a beneficial effect on scar outcome in children and adolescents treated for cancer.

METHODS

A double-blinded placebo-controlled randomized clinical trial was performed. The main outcome was the Vancouver Scar Scale. Secondary outcomes were scar width and scar quality measured using the Patient and Observer Scar Assessment Scale. The patients were divided into an intervention groups and a control group. The intervention group was randomized into active and placebo group. The active treatment consisted of cream with glucocorticosteroid and fusidic acid. The placebo treatment consisted of cream with fusidic acid. Both groups received silicone gel patch after central venous catheter removal. The control group received no specific skin care.

RESULTS

Assessment at 12 months showed that the intervention group had a significantly lower Vancouver Scar Scale and a smaller scar (0,1 cm) compared with the control group ( P =0.00, P =0.02) but no benefit of glucocorticosteroid. The Patient and Observer Scar Assessment Scale showed no significant difference between the intervention and control groups ( P =0.84, P =0.36).

CONCLUSIONS

Silicone gel sheet alone or in combination with application of glucocorticosteroid during sheet occlusion does not clinically improve scar outcome after removal of central venous catheter in children treated for neoplastic diseases.
