Blood precipitate associated with intra-abdominal carboxymethylcellulose administration.

This research paper investigates the occurrence of blood precipitate in horses and a cow following an intra-abdominal infusion of sodium carboxymethylcellulose (SCMC) to prevent abdominal adhesions. It was found that the intensity of the precipitate increased with the administered SCMC dose and was more prominent in foals. Fibrinogen was the only consistently abnormal parameter related to SCMC administration.

Study Overview

• The study was carried out on a group of horses, including one cow. It aimed to examine the effect of sodium carboxymethylcellulose (SCMC), a biochemical administered to prevent abdominal adhesions, on the blood of these animals.
• An observable precipitate was found on the blood films of 15 out of the 16 horses and the cow that were given a peritoneal infusion of 1% SCMC.

Correlation between SCMC Dose and Precipitate Intensity

• The researchers found that the intensity of the precipitate, which could be seen 2 to 3 days post-infusion, was strongly correlated with the administered dose of SCMC.
• The doses of SCMC given ranged from 0.96 to 11.7 ml/kg, the higher the dose, the greater the intensity of the precipitate seen.
• Interestingly, the dose given was inversely correlated with bodyweight, meaning that the lighter the animal, the higher the dose given. As a result, the most prominent precipitates were observed in foals.

Temporal Aspect of Precipitate Appearance

• The precipitate could be observed as early as 24 hours after the administration of the SCMC solution. This precipitate was found to persist for as long as 9 days after the administration.

Fibrinogen Abnormality

• During the study, fibrinogen, a protein in the blood plasma that is essential in the blood clotting process, was the only hematological or biochemical parameter that was consistently abnormal in horses receiving SCMC.
• Mild increases in fibrinogen levels, between 500 to 700 mg/dl, were noted in 11 out of 16 cases. However, these increases were not found to be correlated with SCMC administration, suggesting that further research is needed to understand the link between SCMC and fibrinogen levels.
