[Determination of the magnitude of blood loss in emergency surgery]

Six most frequently used methods of determination of the blood loss value are compared. The method of determination by the blood specific weight is shown to be unreliable in stab-cut wounds. For early stages of the surgical aid calculations by shock index are more reasonable, for the prehospital stage the circulating blood volume should be determined by the method of dilution of indicators allowing to determine the severity of posthemorrhagic hypovolemia, the degree of blood loss being calculated by the globular volume deficit.
