Clinical Analysis of Blood-gas Changes and Acid-base Balance in 67Cases of Acute Stroke Patient

Beijing Haidian Hospital(100080) Liu Haiyan PLAGaneral Hospital Pu Chuanqiang Chinese Rehabilitation Institute Center Zhao Yimin  
To study the Change of blood-gas and acid-base balanoe in 67 acute stroke patients, which inc luded cerebral hemorrhage(32 cases), subarachnoid hemorrhage(3 cases)and cerebral infarction(32 cases), that confirmed by CT scan. We observed that 60% of cerebral hemorrhage (volume30ml), blood broken into ventricle, SAH and large cerebral infarction patients were acid-base unbalance from blood-gas analysis 24 to 48 hours after stroke. Main three kinds of acid-base unbalance were respiratory alkalosis and metabolic acidosis. the second were metabolic acidosis and the third were respiratory alkalosis and metabolic acidosis or metabolic acidosis and metabolic alkalosis. In addition, the mortali-ty of variegated acid-base unbalance is higher than that of only one kind of acid-base unbalance or normal range of blood-gas examination(p0.05).There is sign ificant difference of PaCO2 and HCO3between survival group and death group. It shows they have important relation between the severity of acidbase unbalance and the character and size of v asular disease. It also shows they are positive relationship between the descent of PaCO2 and value of HCO3-and mortality.
