Does episiotomy prevent perineal trauma and pelvic floor relaxation?
We found no evidence that liberal or routine use of episiotomy prevents perineal trauma or pelvic floor relaxation. Virtually all severe perineal trauma was associated with median episiotomy. Restriction of episiotomy use among multiparous women resulted in significantly more intact perineums and less perineal suturing.
The data suggested nociceptors in osteoarthritic joints are more sensitive to inflammatory mediators than in normal joints. Such nociceptive sensitization to inflammatory mediators may participate in the joint pain in osteoarthritis.
