Basic information about surgical wounds
Most surgical treatments are cut through the skin to allow the surgeon to handle deeper tissues or organs. Most surgical Wound Dressing are fully closed at the end of the procedure, and the surgeon is covered with a wound or a sticky adhesive tape on a sutured surgical wound.
Such dressing can be used as a physiological barrier to protect the wound until the skin is restored (within 48 hours), and can absorb the wound exudate, keep the wound dry and clean and prevent bacterial contamination in the external environment.
Some studies have found that dressing to create a moist environment can accelerate wound healing, even if some people believe that the damp environment harmful, such as excessive exudate can cause the wound and the surrounding healthy skin softening and deterioration.
We reviewed the medical literature from July 2013 to find out four early surgical wounds (within 48 hours after surgery to remove the dressings) with delayed removal of the dressing (more than 48 hours after surgery to remove the dressings permanently, but allow the period Replacement dressing) compared to randomized controlled trials.
The degree of deviation of these studies is mostly high or unclear, for example, the failure to perform the test leads to incorrect results. A total of 280 participants who received scheduled surgery were included in this literature review.
140 people removed the dressing within 48 hours after surgery, and 140 wound dressings for more than 48 hours after surgery. Dispose of in an early removal dressing (within 48 hours) or use dressings for more than 48 hours in a random manner similar to throwing copper.
There was no significant difference between the two groups in the presence of superficial surgical site infection (wound infection), superficial wound dehiscence (wound partial dissection leading to skin surface re-cleavage) or experienced serious adverse events.
No complications were reported in the study of deep wound infection or wound complete cleft (wound completely re-split, interrupt wound healing). However, the size of the study is not sufficient to distinguish between minor differences in the incidence of complications.
There is no research report on the quality of life. The early removal of the participants in the dressing group significantly shortened the number of hospital days and reduced the cost of treatment compared to the delayed removal of the dressing group, but this result was based on a randomized controlled trial with a small size and very low quality of evidence.
The Since the present evidence was obtained in three small-scale, randomized controlled trials with very low quality of evidence, we recommend that a randomized controlled trial should be performed to further explore the necessity of post-operative wound dressings for more than 48 hours.
