what is the tubing through which retention sutures are threaded to prevent tearing of the skin? | bolsters |
if closing the wound with sutures would increase infection, the wound is healed by___? | second intention |
wounds that have ragged or weak edges must heal before closure will remain secure. this is healing by ___? | third intention |
the process of granulation occurs in what type of healing? | second intention |
in what type of healing are wound edges brought together and sutured, and wound heals with minimun scarring? | first intention |
this type of healing may require weeks to months because edges are continually inflamed. | second intention |
