摘要

Abstract

Objective

To determine the injury patterns of helicopter crash injuries based on the platform of biological crash equipment with adult minipig suffered from claudo-cephalad decelaration impacts.

Methods

Eighteen adult Congjiang minipigs were randomly divided into 2 groups (

=9). All the pigs were fixed in the supine position and restrained in the rigid seat to simulate the claudo-cephalad deceleration impact. The velocities of crash were 8 m/s for group Ⅰ and 11 m/s for group Ⅱ. From the moment of crash to 6 h after it

the survival situation

morphological changes of injured tissues

blood gas analysis

medical imaging

abbreviated injury scale (AIS)

and injury severity score (ISS) were observed in the 2 groups.

Results

Ultimate velocity of impact were 8.21±0.13 m/s in group Ⅰ

and 10.69±0.41 m/s in group Ⅱ. The peak values of accelerations in pelvis were 127.85 and 164.35 g. The damages located in the central nervous

axial skeleton

and thoracoabdominal organs in both groups. The ISS score was 26.67±5.02 in group Ⅰ

significantly lower than that in group Ⅱ (52.71±6.13

0.05). The total injuries were severe and life-threatening.

Conclusion

The animal models of severe and life-threatening helicopter vertical impact injuries are established successfully. And the characteristic of spleen rupture and pulmonary contusion are major injuries in the thoracoabdominal region.
