Abstract:
After observing inconsistencies in care of acute surgical wounds healing by secondary intention and reviewing the potential cost savings of implementing clean dressing change technique policies, surgical nurses at a university-based medical center monitored supply usage and infection rates of these wounds using a nonexperimental, longitudinal study design. Staff from two acute care surgical units provided data for 3 months before and 3 months after standardization of wound care to a clean wound care technique. All adult patients requiring dressing changes three times per day with normal saline moistened gauze of their open surgical wound(s) participated in the study. Before changing the wound care procedures, nine (9) of 1,070 (0.84%) admissions to the two surgical units had a surgical site infection. During the 3 months following implementation of clean wound care protocols, eight (8) surgical site infections were documented in 963 admissions (rate.83%). Dressing supply costs were $380 less. In this study, using nonsterile wound care procedures for wounds healing by secondary intention did not negatively impact infection rates and saved supply costs.

Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
