BACKGROUND
Despite all recent developments, bleeding is still one of the main causes of increasing morbidity and mortality following both trauma and elective hepatic surgery. The main goal of treatment is stop the bleeding immediately. In this study, the hemostatic and histopathological effects of Ankaferd blood stopper (ABS), oxidized cellulose (OC), and calcium alginate (CA) were compared in an experimental liver injury.
METHODS
Forty Wistar albino rats were randomly divided into four groups of ten animals each, receiving 0.9% NaCl, CA, OC, or ABS following liver resection. After 5 days, the samples from the resection site were acquired for histopathological evaluation. The efficacy of the agents was assessed using the hematocrit level and histopathological examination. Statistical analyses were applied.
RESULTS
The amount of bleeding was lowest in ABS-treated rats, followed by those treated with OC, CA, and NaCl, respectively. The difference among the groups was statistically significant (P < 0.001). ABS-treated rats also had significantly less necrosis than those receiving OC; other differences in this regard were not significant. Inflammatory status was significantly different between OC- and CA-treated rats (P < 0.05) but not among the other groups (P > 0.05). No significant difference was determined between the groups regarding granulation (P > 0.05).
CONCLUSIONS
ABS reduced the volume of bleeding in liver surgery and partial liver resection. The hemostatic effect of CA was limited.
