[Unspecific tissue reactions caused by glove powder]
Summary
Surgical glove powders containing starch, unlike talcum powder, showed minimal adhesion formation in rats. These resorbable powders were associated with fewer foreign body granulomas and were largely resorbed by the study
Area of Science:
- Histopathology
- Toxicology
- Biomaterials
Context:
- Surgical glove powders are widely used in medical procedures.
- Talcum powder is a known cause of foreign body reactions and adhesions.
- Resorbable, starch-based powders are alternatives to talcum.
Purpose:
- To compare the histopathological effects of resorbable surgical glove powders (Brauns and Bio-sorb) with talcum powder in a rat model.
- To evaluate the potential for adhesion formation and foreign body reactions.
Summary:
- Macro- and histopathological examinations were conducted on 200 Wistar rats treated with Brauns resorbable surgical glove powder, Bio-sorb surgical glove powder, or talcum powder.
- Talcum powder induced foreign body granulomas and adhesions.
- Starch-based powders caused an initial inflammatory response followed by solitary granulomas, with minimal adhesion development and significant powder resorption over 12 weeks.
Impact:
- Resorbable starch-based surgical glove powders demonstrate a favorable safety profile compared to talcum powder.
- These findings suggest that starch-based powders may reduce the risk of post-surgical adhesions.
- Further research could explore the long-term biocompatibility and efficacy of these resorbable materials.

Overview
Hand hygiene
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.

Personal Protective Equipment
Personal protective equipment (PPE) is unique clothing or equipment worn by an employee to minimize or prevent exposure to infectious agents. PPE creates a barrier between the employee and the infectious materials. PPE must be readily available in the patient care area. PPE includes gloves, gowns and aprons, masks and respirators, goggles, face shields, shoes, and headcovers:
PPE Use in Healthcare Settings I: Donning
Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...
PPE Use in Healthcare Settings II: Doffing
The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.
Hypersensitivity Reactions: Delayed Hypersensitivity Reactions
Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...
