    A hydrocolloid dressing is an opaque or transparent [1] dressing for wounds. A hydrocolloid dressing is biodegradable, [2] breathable, and depending on the dressing selected, may adhere to the skin, so no separate taping is needed.

  9. Carbonated soda treatment of phytobezoars - Wikipedia

    en.wikipedia.org/wiki/Carbonated_soda_treatment...

    Carbonated soda treatment of phytobezoars is the use of carbonated soda to try to dissolve a phytobezoar. Bezoars consist of a solid and formed mass trapped in the gastrointestinal system, usually in the stomach. [1] [2] [3] These can also form in other locations. [4] [5] Carbonated soda has been proposed for the treatment of gastric phytobezoars.
