Abstract:
Objective To test the performances and applicability of the pressure infusion cuff and blood warmer under severe cold environments in the field.Methods Under the severe cold conditions in the field,the simulated hemorrhagic shock patient was placed on a stretcher and transported to a transfer vehicle 2 km away,a pressure infusion cuff and blood warmer was used to perform fluid resuscitation and heating and pressurization blood transfusion during the transport,and the effect of heating and pressurization of the device during the transport was evaluated;two healthy adult male pigs were selected to construct animal models of hemorrhagic shock from war wounds,of which one pig was used as an experimental animal to be treated by blood transfusion with a pressure infusion cuff and blood warmer and the other pig was recognized as a control animal to be treated by blood transfusion using commercially available inflatable pressurized bags and thermostats,and comparison analysis was carried out on the changes in vital signs of animals before and after treatment by the 2 methods of warming and pressurization and the effects of warming and pressurization transfusion.Results The pressure infusion cuff and blood warmer gained advantages in convenience,efficiency and applicability during patient transport;the experimental animal behaved better than the control animal in vital signs such as blood volume,pressure and respiration,transfusion speed and fluid warming.Conclusion The pressure infusion cuff and blood warmer has high efficiency and is applicable under severe cold conditions in the field.[Chinese Medical Equipment Journal,2023,44(11):117-120]
