Uroperitoneum in 32 foals: influence of intravenous fluid therapy, infection, and sepsis.

The research study analyzes the impact of intravenous fluid therapy, infection, and sepsis on foals diagnosed with uroperitoneum. The study compares these variables between foals presenting with this condition and those developing it while in hospital.

Objective and Methodology of the Research

• The study sought to understand the effects of various elements related to the development and treatment of Uroperitoneum (UP) in foals – very young horses. This condition causes urine leakage into the abdominal cavity.
• To achieve this, it compared historical, physical, laboratory, and diagnostic data between the foals that came in already with UP and those that developed UP while hospitalized for other reasons.
• Key areas of interest included the presence of electrolyte abnormalities, evidence of infection or sepsis, and the occurrence of complications during the surgical correction of the problem causing UP.

Findings of the Research

• The research discovered that foals that developed UP during their hospital stay often had a history of dystocia (difficulty in birthing) and were usually very young (less than 48 hours old) when admitted. Their key clinical signs were compatible with intrauterine compromise, or a presumed lack of oxygen or blood supply (hypoxia or ischemia), with or without sepsis.
• Conversely, foals that were referred to the hospital with suspected UP often had additional issues unrelated to the urinary system. They usually had low sodium (hyponatremia) and high potassium (hyperkalemia) levels on presentation.
• Foals that received intravenous fluid therapy using a balanced electrolyte solution did not develop the typical pattern of electrolyte abnormalities. However, they often exhibited an increase in serum creatinine and a decrease in urine production, which suggests kidney, dysfunction.
• Infection was found in 63% of these foals, and 78% exhibited signs suggestive of sepsis or infection, indicating a high risk of concurrent infection in foals with UP.
• Complications during anesthesia occurred in 16% of the foals undergoing surgery to correct UP, but only half of these foals had high potassium levels. This reveals that other hidden factors besides hyperkalemia might be contributing to anesthetic complications.

Implications of the Research

• The research suggests that complications such as hypoxia, ischemia, infection, and sepsis may predispose foals to UP development.
• The finding that electrolyte balance can be maintained through intravenous fluid therapy highlights its importance in managing UP.
• The study’s findings on the prevalence of infection and sepsis among foals with UP underline the importance of monitoring for concurrent infections in these cases.
• The research also puts forth that there might be more factors at play behind the occurrence of anesthetic complications, which warrants further investigation.
