Effect of antiseptic agents on skin flora of the perineum of men with spinal cord injury.

Male patients with spinal cord injury are frequently colonized with P. aeruginosa and K. pneumoniae on the perineum. Regular bathing with bar soap has not influenced this colonization. We have attempted to remove these bacteria using antiseptic agents. The number of P. aeruginosa, K. pneumoniae and total aerobic bacteria on the perineum and the penile shaft was determined before and after cleaning with bar soap, chlorhexidine, povidone-iodine and pHresh. Povidone-iodine and chlorhexidine had no advantage over bar soap or pHresh in the removal of P. aeruginosa or K. pneumoniae from the perineum of patients with spinal cord injury.
