Objective:The aim of this study was to investigate effects of oral carbohydrate (maltodextrin) administration on splanchnic circulation and erythrocyte deformability in endotoxemic rats.

Methods: 

Forty-eight male Wistar rats (weighing 180–200 g) were used in this study. Group SC (n=8) was designated as sham control. Group S (n=10) served as starvation only. Group S+ lipopolysaccharide [LPS] (n=10) was subjected to endotoxemia. Group CH (n=10) received carbohydrate (Preop, 240 mOsm/lt, 12.5% maltodextrin, sodium 50 mg), 0.5 mL in every 4 hours for 48 hours, through orogastric lavage. Group CH+LPS) (n=10) ingested same amount of carbohydrate and was subjected to endotoxemia. Endotoxemia was induced by intraperitoneal injection of 30 mg/kg of LPS. Erythrocyte deformability index was measured using a filtration technique 5 mm in diameter polycarbonate filter with a fixed flow (1.5 ml / min.) Pyloric, ileal, portal and hepatic surfaces were measured by a laser Doppler microvascular perfusion monitor.

Results: 

According to control group, (S + LPS) group, deformability was significantly and negatively affected (p <0.05). Deformability of (S + LPS) and (Ch+LPS) group was measured positively affected although there was no significant difference. LPS caused a significant decrease in hepatic surface blood flow (p<0.05). Ingestion of carbohydrate significantly improved (p<0.05) ileal, pyloric blood flows in endotoxemic rats. Increases in hepatic surface blood flow were found in S and Ch groups, although these changes were not statistically significant.

Conclusions: 

These results have shown that endotoxemia caused a significant decrease in splanchnic blood flow. We suggest that decreased blood flow with an increase in bacterial translocation can cause infection development in the gastrointestinal system.
