[Prolonged intraosseous blockades in first aid practice].

Under conditions of the emergency medical service 217 prolonged blockades were fulfilled in 138 patients with different injuries of extremities. The anesthesizing mixture was composed of 5% of novocaine and a large moplecule protein preparation (aminokrovin, aminopeptide, 8% gelatinol). The prolonged intraosseous blockade was found to be a highly effective procedure in the complex treatment of traumatic shock. No infectious complications were noted.
