Perineal skin injury: extrinsic environmental risk factors.
Little research has been performed to evaluate factors that may exacerbate perineal skin injury in the adult population. But extensive research has been done and knowledge has been gained from studies with diaper dermatitis in infants. Our objectives in writing this article are to define the anatomical area affected, the terms used, and to review the available literature for diaper dermatitis in infants, elucidating the similarities and differences between diaper dermatitis in infants and perineal dermatitis in adults. The six extrinsic environmental factors that have been identified and extensively studied in diaper dermatitis are skin wetness, urine, ammonia, feces, local skin pH and microorganisms. Although the complex interactions of the six factors are still not totally defined, we do know that to prevent perineal skin injury, it is helpful to prevent excessive skin hydration, minimize the interaction of urine and feces, minimize local microorganisms, and maintain skin near its physiologic pH. In general, the six extrinsic factors can be extrapolated and applied to the care of adults. Further research in adult fecal enzymes and pH is still necessary.
