Background: One of the most frequent life-threatening emergencies is extremity
haemorrhage. In such cases, patient survival depends on a fast on-scene intervention.
Thus, both the potential witnesses and medical emergency staff should have the ability
to control haemorrhages. However, simulator-based courses do not fully reflect the
structures and physiology of the human body. Therefore, invasive procedure training in
trauma patients is limited.

Objective: The aim of the study is to evaluate the effectiveness of cadavers as
educational tools during a training course in extremity haemorrhage control with the
use of the Combat Application Tourniquet (CAT).

Methods: The study was conducted among 31 paramedic students, who applied a
tourniquet to the upper extremity of an unembalmed (fresh) human cadaver with
simulated bleeding. Two time measurements were performed, the latter being
preceded by a short CAT application training on a human cadaver.

Results: The mean time needed to stop the simulated bleeding in the first attempt was
38.33 seconds (SD ± 35.14). After the training, the mean time decreased to 20.58
seconds (SD ± 5.77). A statistically significant difference was observed between these
two values (p=0.004).

Conclusions: The study demonstrated that training conducted on human cadavers led
to a significant improvement in the effectiveness of CAT use. Cadavers constitute a
high-quality educational tool which, after adequate preparation, allows for practising
invasive medical procedures such as extremity haemorrhage control.
