Evaluation of Carolina Rinse solution as a treatment for ischaemia reperfusion of the equine jejunum.

The research article discusses the evaluation of Carolina Rinse (CR) as a method of treating ischaemia reperfusion, a common complication in equine jejunal surgeries, which is conditioned by reduced blood flow followed by its restoration. The study reveals a significant decrease in inflammation and scarring associated with reperfusion injury when using the CR solution.

Objectives and Methods

The research aimed to investigate whether Carolina Rinse, a solution previously recognized for reducing inflammation and subsequent scarring associated with reperfusion injuries, could have similar effects on the equine jejunum.

• The experiment involved both the intra-arterial infusion and the topical application of Carolina Rinse to the equine jejunum subjected to induced ischemia.
• The study further compared treated and untreated intestines by evaluating vascular permeability, neutrophil accumulation (white blood cells that remove bacteria and cellular debris), and serosal scarring.

Results

The outcome of the study indicated promising results when incorporating Carolina Rinse as a treatment method in the reperfusion of the equine jejunum.

• Both the intra-arterial and topical use of Carolina Rinse maintained a normal osmotic reflection coefficient, a crucial factor in ensuring the normal functioning of cell membranes.
• The solution reduced the migration of neutrophils into the serosa, the membrane lining the abdominal cavity and covering the abdominal organs, during the reperfusion process.
• After 10 days, the intestine treated with Carolina Rinse showed fewer signs of scarring and fibroblast proliferation, indicative of less tissue damage. Notably, the treated intestine looked normal.
• At biopsy sites in the treated intestine, there was a significant decrease in fibroplasia, a phase of wound healing where the wound is filled with granulation tissue.

Conclusions

From the results, the researchers concluded:

• Carolina Rinse reduces immediate reperfusion injury and limits post-operative scarring when used both intra-arterially and topically during jejunal ischaemia.
• The solution should ideally be used as a local perfusate, reducing potential damage to the mesenteric arteries that could result from systemic use.
• Carolina Rinse was recommended as a supplementary treatment in surgical procedures and post-operative care plans to manage surgical complications better.
