Are Colloidal Silver Gel and Betadine Effective Against Infections - Treatment Practices

Betadine And Colloidal Silver Gel for wound infections

from both colloidal silver gel As well as topical. From antiseptic betadine known to be effective kill infectious bacteria and are therefore suitable for disinfecting wounds. Now a current study suggests that the effects of the two agents complement each other in combination, so that the overall effect is stronger than the individual effect.

researchers of Association for Professionals in Infection Control in Arlington, Washington, has demonstrated that a Combination of Betadine and Colloidal Silver Gel Inhibits the growth of common infectious bacteria more effectively than either agent alone. The results were recently published in “”.american journal of infection control” Presented.

Wound Infection Still a Medical Problem

Shape sore more heavy burns are prone to entry of microorganisms, In addition, wounds have a risk that biofilms will adhere to the wound surface and delayed treatment Or even stop it.

“Despite significant advances in wound management and supportive care, wound infection remains a serious problem, particularly in large burns”One of the study authors explains Dr. Jonathan Copele,

According to him, it first studywho systematically evaluated the use of betadine versus colloidal silver gel alone, and betadine in combination with colloidal silver gel for bacterial clearance and biofilm growth.

Silver enhances the effects of Betadine

The disinfectant betadine is widely used to treat and prevent wound infections because it has a particularly broad spectrum of antimicrobial activity. Nevertheless, the remedy is ineffective against some bacteria.

Therefore, bandages, some of which contain silver, have long been used to support healing and prevent wound infection. Practice has already suggested at this point that silver Uses a different mechanism to kill microorganisms than Betadine.

What was checked?

The team around Dr. So Kopel compared the effectiveness of a 5% betadine solution alone and that of a colloidal silver (Ag) gel alone. Combination of 5% Betadine Solution with Ag Gel,

The agents were used against five bacterial strains most often responsible for wound infections, including

  • Staphylococcus aureus (Sauris),
  • Pseudomonas aeruginosa (Peruginosa),
  • Klebsiella pneumoniae (K. pneumoniae),
  • Staphylococcus epidermidis (S. epidermidis),
  • Methicillin-resistant S. aureus (MRSA).

The researchers soaked cellulose papers with the three test solutions and placed them on the respective biofilms of the bacterial strains, which had been exposed for the first 24 hours to spread. Then, using standard tests and imaging, the working group checked how effective the three agents were at repelling bacteria.

learning outcome

The evaluation showed the following results:

  • The use of 5 percent betadine alone was able to inhibit four out of five bacterial cultures by about 90 percent. However, P. aeruginosa, betadine showed little or no effect.
  • Ag-Gel alone inhibited bacterial growth by 100 percent in four of the five bacterial strains. Colloidal silver gel was less effective only against K. pneumoniae.
  • The combination of Betadine and Ag Gel resulted in complete inhibition of all five bacterial strains tested.

Colloidal silver works differently from betadine

The results support the theory that colloidal silver has a different bactericidal mechanism than betadine. “This study provides important new insights that may help improve infection prevention and treatment to reduce this burden.”, summarizes Linda Dickey, president of the Association for Professionals in Infection Control.
