Background

To construct a new and improved model of acute subdural hematoma in rats.

New method

30 male adult Sprague-Dawley rats(SD rats) were selected and randomly divided into two groups. The traditional model group was based on Miller's model construction method, and the improved model group was based on improved needle, injection site and operation method. The improved model was evaluated by comparing the physiological indicators, behavioral scores, magnetic resonance performance and HE staining results of the two groups of rats.

Results

The physical signs of the rats in the two groups were similar. The survival rate of the improved group was higher than that of the traditional group. The hematoma in the improved model was thicker and concentrated in the ipsilateral side, as revealed by HE staining and MRI. The improved method has less intrusions on the cortex around the injection site and is more stable than the traditional model.

Comparison with existing method(s)

The operation difficulty of the improved model is reduced and easier. The survival rate of the improved group was higher than that of the traditional group. And the improved model will have more research possibilities.

Conclusion

The improved model is based on the traditional model. Although it has some shortcomings, it can also be used in different research fields of the traditional model. The operation for the improved model is easier to perform. And the improved model has more applications in research.
