Vaseline gauze, also known as oil gauze, is a very common type of gauze used in clinical practice. Vaseline gauze is composed of sterile gauze that has been degreased and petroleum jelly. Patients who suffer from trauma, if the wound bleeds more, or if the wound is more contaminated, with more blood and ooze, covering Vaseline gauze in this case can block the contact between bacteria and skin, thus reducing the possibility of infection. In addition, Vaseline gauze can also promote the growth of granulation tissue on the wound surface and facilitate wound healing. Wounds that bleed more may form crusts when applying normal gauze dressings, and the crusts may stick to the gauze, while applying petroleum jelly gauze will avoid this situation and will not irritate the wound when changing the dressing on it.
