Introduction
This study was constructed to compare the effects of resuscitation with gelatine and hydroxyethyl starch (HES) on coagulopathy, haemodynamics, and tissue damage during an uncontrolled haemorrhagic shock model in rats.

Material and methods
Twenty 6-month-old Sprague-Dawley rats were included in the study and divided into 4 groups. There was no haemorrhage in the sham group. The others were randomised into haemorrhage without volume replacement (control group), haemorrhage and gelatine (group G), and haemorrhage and HES (group V). Blood samples for thromboelastogram and annexin 5 values were obtained before bleeding and after resuscitation.

Results
In the control group, R (16.18 ± 2.74) and K (5.8 ± 1.1) were significantly higher than in all other groups (P = 0.001), and the TEG alpha angle was 39.54 ± 5.94°, which was found to be significantly lower than in the sham group (P = 0.001). In group V, the TEG MA value was found to be significantly lower at 30.54 ± 8.89 (P = 0.001). The annexin A5 value was significantly higher in the control group, group V, and group G than in the sham group and was highest in the control group (P = 0.001). Lung damage score measurement was 0.60 ± 0.19 in the control group, higher than in the gelatine and HES groups (P = 0.001).

Conclusions
Lung tissue damage and coagulation were positively affected by HES or gelatine resuscitation. A reduction in clot formation in the HES group might be observed due to the possible negative effect on platelets. Therefore, we concluded that the use of gelatine might be advantageous until blood transfusion is initiated in traumatic haemorrhagic shock.
