Effect of needle size and type, reuse of needles, insertion speed, and removal of hair on contamination of joints with tissue debris and hair after arthrocentesis. | Semantic Scholar (2024)

Angled needle insertion reduces joint contamination with tissue and hair after arthrocentesis, and spinal needles should be inserted with a stylet in place and 22 g spinal needles are preferable to 20G spinal needles.

Nineteen-gauge needles significantly increase the risk of joint contamination with hair compared to 20 g needles; non-lubricated 19 g needles have the greatest risk.

In clean shorthaired dogs without visible evidence of dermatological disease, leaving arthrocentesis sites unclipped rather than performing traditional surgical clipping did not result in increased bacterial skin counts after aseptic skin preparation.

This research aims to further understand the interfacial mechanics of coated needle insertion by studying the forces at the needle and tissue interface and developing an analytical insertion force model through a combined experimental and numerical method.

Clinical, ultrasonographic, and arthroscopic characteristics of confirmed hair shafts within synovial structures of seven horses showed support for the use of ultrasonography as a complementary diagnostic method for ruling out hair foreign material in horses with signs of inflammatory or septic synovitis/tenosynovitis.

The findings in the present case demonstrate that in the case of a penetrating head trauma with a wooden foreign body, surgical removal and active debridement should be the treatment of first choice.

Septic arthritis is an uncommon complication of IAM in horses, yet the risk is substantially higher than that reported in humans and may be greater with certain types of corticosteroids.

It is believed that better quality control during manufacture of epidural and intradural needles can help to eradicate the rare neurological complications derived from the removal of epithelial cells and their subsequent deposit inside the spinal channel.

The presence of hair over the midcarpal and distal interphalangeal joints does not appear to inhibit the ability of antiseptics to effectively reduce bacterial flora to an acceptable level for arthrocentesis in horses.

Skin disinfection before insertion of an acupuncture needle is controversial and observations of lack of infection following injections without prior skin disinfection support this; however, contamination by micro-organisms not normally resident on skin can pose a higher risk of infection.

Endoscopic surgery makes a valuable contribution to the management of synovial contamination and infection in non-Thoroughbred horses, including a group combining nonsurviving animals and those with reduced post operative performance.

The incidence of postspinal headache appears to be related not only to the gauge of the needle but also to its capacity for coring, and this possible aetiology is presented as an alternate hypothesis.

Closed suction drainage appeared to be a useful treatment in horses with infectious arthritis, and although arthroscopy was not necessary, it facilitated fibrin removal, lavage, and partial synovectomy.

The results confirm that the phlebotomy cannula may cause superficial tissue fragments to be punched out of the donor’s skin during blood donation and should be taken into account when devising methods to reduce bacterial contamination in blood products.

Balloon constant rate infusion systems may be used effectively in treatment of septic arthritis, septic tenosynovitis, and contaminated synovial wounds and clinical response and long-term outcome appeared to be comparable to results obtained with other techniques.

There is at present no single consensus technique for intra-articular and soft tissue injections amongst British consultant rheumatologists, and a wide divergence of practice in almost every aspect of technique is shown.

The results of bacterial cultures suggest that the initial antimicrobial agents used should be effective against penicillin-resistant staphylococci.
