Silver was used as a poison test material in ancient times. In modern times, through the advancement of material science, silver can be divided into extremely small particles. In the field where the particle size is reduced to sub-micron, the physical and chemical properties of silver have undergone great changes. , silver produces many different effects (such as: anti-bacteria, anti-virus, anti-inflammation, promotion of wound healing, etc., can refer to thispaper), and therefore have many different clinical uses, and among them, the most common and closest to the needs of the public is the treatment of wound infections.
In the current medical environment, the use of silver (ion/particle state) is still relatively limited, and the silver-containing medical materials used are also relatively expensive. Taking burns as an example, silver-containing ointment is often applied to the affected area in clinical practice, and it needs to be cleaned and applied regularly every day; for more serious wounds that bleed a large amount of tissue fluid (such as bedsores, deep-seated infections), it may also be considered to use a silver-containing ointment in clinical practice. Silver-containing dressings with hygroscopic materials are more expensive, and the dressings need to be replaced every day to prevent the wound from being filled with tissue fluid and becoming a petri dish for bacteria. However, in fact, besides ointments and dressings, silver-containing medical materials also come in the form of sprays, which are more convenient to use and relatively affordable in price. In addition, high-quality silver sprays have excellent bactericidal effects , as shown in the following two diagrams, for common pathogenic bacteria (Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Candida albicans, Aspergillus niger), silver in addition to being able toIn a short period of time (1 minute), the bactericidal effect of 99.9% is achieved, and this effect can also be maintained for several weeks (14, 28 days), so it is very suitable for clinical application.
After understanding the super strong bactericidal effect that silver can achieve, the following will provide some examples to share with you, so that everyone can better understand the clinical application of silver spray:
severe acne skin
Second degree burns (extensive blisters and redness)
diabetic foot(infected tissue necrosis in extremity wounds)
However, silver isThe quality of the clinical application effect is related to the particle size, concentration, dosage, stability, chelation method and other factors of the silver material used., and can be used clinicallySilver-containing materials need to have a medical certificate. Do not use silver-containing products of unknown origin on the affected area,in addition,Periodic evaluation by a clinician familiar with silver-containing materials is recommended during treatment, in order to make the utility of the silver material more effective.
In life, the author often carries a small package of silver spray with him in case of emergency. When going abroad, it is an indispensable item in the first aid kit; More people understand the application of silver spray and take care of more similar clinical needs. Finally, the author still wants to remind everyone that the use of silver spray should be discussed with clinicians first, and everyone is welcome to come to my serviceand a clinicChat with me~! I wish everyone a healthy and happy life!
