Hand hygiene01:23

Hand hygiene

6.5K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Chemical Agents for Microbial Control01:27

Chemical Agents for Microbial Control

1.4K
Chemicals play important roles in controlling microbial growth by targeting microbial structures and functions as sanitizers, antiseptics, disinfectants, and sterilants.Alcohols are commonly used sanitizers, effectively disrupting lipid membranes, which compromises cell integrity. They are also used as antiseptics and disinfectants due to their rapid action and versatility.Phenols and their derivatives phenolics , known for denaturing proteins and disrupting cell membranes, are particularly...

Antimicrobial Effectiveness01:28

Antimicrobial Effectiveness

1.8K
The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...

Handwashing II: Pre-procedure and Initial Procedure Steps

1.6K
The pre-procedure steps of handwashing include removing jewelry and rolling up sleeves. However, many organizations allow staff to wear wedding rings.
The hand washing procedure itself includes the following steps. First, cover cuts, if any, on hands with a waterproof dressing. Cuts and abrasions can become contaminated with bacteria hindering the ability to clean the area thoroughly. In addition, repeated hand washing can worsen an injury.  The nails must be short and clean, without nail...

Physical Properties of Alcohols and Phenols02:32

Physical Properties of Alcohols and Phenols

17.2K
Alcohols are organic compounds in which a hydroxy group is attached to a saturated carbon. Phenols are a class of alcohols containing a hydroxy group attached to an aromatic ring. The physical properties of the alcohols and phenols are influenced by hydrogen bonding due to the oxygen–hydrogen dipole in the hydroxy functional group and dispersion forces between alkyl or aryl regions of alcohol and phenol molecules.
Alcohols possess a higher boiling point than aliphatic hydrocarbons of similar...

Surface Membrane Barriers01:18

Surface Membrane Barriers

3.3K
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Summary
This summary is machine-generated.

Polyhexamethylene biguanide hydrochloride (PHMB) shows antimicrobial effects in vitro. However, more robust clinical studies are needed to confirm its safety and efficacy for skin, wound, and mucosal applications.

Area of Science:

  • Microbiology
  • Dermatology
  • Infectious Diseases

Background:

  • Polyhexamethylene biguanide hydrochloride (PHMB) is a widely used disinfectant and antiseptic.
  • This review focuses on PHMB's application as an antiseptic agent.

Purpose of the Study:

  • To summarize existing data on the antimicrobial efficacy of PHMB in vitro.
  • To evaluate the clinical effects and safety profile of PHMB on skin, wounds, and mucosa.

Main Methods:

  • A literature search was conducted using PubMed, focusing on articles published within the last five years (up to June 2014).
  • A total of 332 articles were identified, with 27 ultimately included in the review.

Main Results:

  • In vitro studies confirm PHMB's antimicrobial activity against Gram-negative bacteria, Gram-positive bacteria, and Candida albicans.
  • Clinical studies reviewed were generally small, lacked robust controls, and were often industry-sponsored.
  • Limited adverse effects were reported in the clinical studies.

Conclusions:

  • PHMB demonstrates in vitro antimicrobial properties against common pathogens.
  • Current clinical evidence supporting PHMB's use on skin, wounds, and mucosa is limited due to study design.
  • Larger, well-controlled clinical trials are necessary to establish definitive recommendations for PHMB's clinical application and safety.
