To explore the feasibility of portable ultrasound guided pre-hospital treatment of traumatic cerebral hemorrhage through animal experiments.

Six female Wuzhishan pigs were used in this study. Ultrasound-guided intraventricular catheterization was performed on the animals with traumatic cerebral hemorrhage. The time of small bone window craniotomy and the changes of signs before and after operation were recorded.

Traumatic cerebral hemorrhage was successfully in six experimental pigs, with one pupil dilated and ipsilateral limbs paralyzed. The success rate of model establishment by this method was 100%. It took (2.33±0.61) minutes to make a bone window with a diameter of 1 cm with a micro-electric craniotomy drill. After decompression by ventricular catheterization guided by portable ultrasound in the animal models, the pupillary volume of the experimental animals was gradually retracted and the limb activity was gradually restored after (2.4±0.7) h. The systolic blood pressure [(127±5.66) mmHg] was higher than that before decompression [(103.33±3.33) mmHg; t=4.996, P=0.004], and the heart rate declined to (75.17±4.31) beats/min before decompression, and increased to (90.17±3.76) beats/min 2 h later (t=5.839, P=0.002).

Ventricular catheterization guided by portable ultrasound makes it feasible to control the injury rapidly in traumatic cerebral hemorrhage so as to save time for further surgical treatment and improve the prognosis. The feasibility and practicability of this method provide a new avenue for the pre-hospital clinical treatment of patients with traumatic cerebral hemorrhage.
