|October 1, 2013
Summary
Both chlorhexidine and polyhexanide antiseptics cause significant human osteoblast cell death. Cautious use is recommended in septic surgery to prevent severe toxicity and ensure patient safety.
Area of Science:
- Biomedical Engineering
- Cell Biology
- Surgical Innovation
Background:
- Antiseptics are crucial for wound care and preventing surgical site infections.
- Chlorhexidine and polyhexanide are widely used broad-spectrum antiseptics.
- Their impact on human osteoblasts, critical for bone health, remains under-investigated.
Purpose of the Study:
- To assess the in vitro toxicity of clinically relevant concentrations of chlorhexidine and polyhexanide on human osteoblasts.
- To evaluate the safety and applicability of these antiseptics in septic surgery.
Main Methods:
- Human osteoblasts were isolated and cultured in vitro.
- Cells were exposed to 0.1% chlorhexidine and 0.04% polyhexanide.
- Toxicity was measured via cell morphology, vital cell counts, and lactate dehydrogenase (LDH) release.
Main Results:
- Microscopic analysis revealed significant damage to osteoblast cell structure.
- Both antiseptics increased LDH activity, indicating cell damage.
- A substantial reduction in the number of viable osteoblasts was observed.
Conclusions:
- Chlorhexidine and polyhexanide induce significant osteoblast cell death at typical exposure levels.
- Judicious application of these antiseptics is advised in septic surgery to mitigate osteoblast toxicity.
- Further research may explore alternative or modified antiseptic strategies for bone infection management.

01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

01:23Hand 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.

01:31Osteoclasts in Bone Remodeling
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during bone...
