Dakin's solution is a dilute solution of sodium hypochlorite (0.4% to 0.5%) and other stabilizing ingredients, traditionally used as an antiseptic, e.g. to cleanse wounds in order to prevent infection. [1] The preparation was for a time called also Carrel–Dakin solution or Carrel–Dakin fluid. [2]
Saline solution for irrigation. Normal saline (NSS, NS or N/S) is the commonly used phrase for a solution of 0.90% w/v of NaCl, 308 mOsm/L or 9.0 g per liter. Less commonly, this solution is referred to as physiological saline or isotonic saline (because it is approximately isotonic to blood serum, which makes it a physiologically normal solution).
- delivery of an irrigant (usually normal saline) under direct pressure that is produced by an electrically powered device, useful in cleaning e.g. chronic wounds. [ 1 ] Look up lavage in Wiktionary, the free dictionary.
Water as a cleansing agent, especially in chronic wounds has been proposed [23] and is widely used [26] especially in the management of infected wounds. [27] Despite the plethora of work focussing on the value of water/saline in wound cleansing there is no current consensus as to whether water has an active role to play in the promotion of healing.
The dressings used for the technique include foam dressings, sealed with an occlusive dressing intended to contain the vacuum at the wound site. [1] Where NPWT devices allow delivery of fluids, such as saline or antibiotics to irrigate the wound, intermittent removal of used fluid supports the cleaning and drainage of the wound bed. [6]
The proximal end of the catheter is connected to the port within the skin pocket later after irrigation of the pocket with normal saline. [3] The port is then sutured on two sites to the underlying muscles. The tip of the catheter is checked for kinks and position using a fluoroscope. Besides that, aspiration of blood and contrast injection ...
The dressing should be changed and the wound irrigated with normal saline at least twice each day. [4] In addition, it is recommended to administer an antibiotic active against staphylococci and streptococci, preferably vancomycin when there is a risk of methicillin-resistant Staphylococcus aureus. [4]
After a few days the dressing has a tendency to dry out, and must be changed often. Left on too long, it can engage with wound tissue and wound secretions when drier, and be more difficult to remove. [4] This tendency to adhere to wounds is usually resolved by soaking the wound for a few minutes with normal saline. [3]
