In our experiments on 5 pigs of weight between 40-50 kg we've noticed changes of the parameters occurring precociously during the initial stage of the shock. Particularly we observed a sudden reduction of diuresis reaching total anuria in 15 min and persistence of this anuria for the entire time of the shock (120 min). Immediately after introduction of the removed blood the arterial pressure and the diuresis return to normal value. Concerning the blood flow in renal artery it was observed a gradual decreasing to 10-30 ml/min (normal value = 120-180 ml/min). After the restoration of the blood volume we did'nt notice a clean resumption of the flow although arterial pressure reached normal levels (flow value = 70% of the basal value). The hematic level of K+ undergoes a sudden increase that reaches. Maximal level compatible with animal's life. Within 45-60 min from the beginning of the shock and than decrease with restarting of the diuresis. Creatinine reaches 2 mg/ml in 60 min and remain constant during the following 120 min. The value of the plasma renin were precociously raised, reaching values particularly elevated after 90-120 min from the beginning of the shock and decreasing rapidly with the introduction of the removed blood (parallel behaviour of the arterial pressure). |
