title: Use of occlusive dressings on central venous catheter sites in hospitalized children.
abstract: Although the use of occlusive dressings in adults has been criticized in the literature, there has been little written on their use in the pediatric population. Management of dressing sites requires nursing judgement unique to this population. This study focused on the progression of microbial colonization and signs of inflammation occurring beneath repeated occlusive dressings applied to central venous catheter (CVC) insertion sites among 104 hospitalized children (neonate to 18 years). A noninvasive skin culture was obtained within 24 hours of CVC placement, 3 to 7 days later before the next routine dressing change, and at the time the CVC was discontinued or the child was discharged, whichever occurred first. Results showed a significant increase in microbial growth (p < or = .001) at the second dressing change, when serosanguinous drainage was heaviest, and continued significant growth (p < or = .001) when the dressing was discontinued. This microbial growth pattern was curious in the face of a 0.3% systemic sepsis rate. When neonates under 1,800 g were excluded from calculation, the pattern was not notable (p = .2119). Findings suggest the use of occlusive dressings during prolonged hospitalization for tunnelled CVCs does not lead to increased site infections in children over 1,800 g.
