In this study, some hematological and hemodynamic changes were studied in hypovolemic dogs. For this purpose 20 dogs were used as material. After anasthesis with sodium tiopental (30 mg/kg iv) in dogs, hemorrhagic shock was experimentally created. The average arterial compressor (OAB) was reduced to 40±5 mmHg and kept at this level for 30 minutes (hypotensive period). At the beginning of the study and at the end of the hypotensive period, blood samples for the determination of the hemogram and blood gases were taken, other parameters were recorded. Pre-test average arterial pressure (OAB), average systolic pressure (OSB) and average diastolic pressure (ODB) in order; 120. 7, 151.4 and 105.4 mmHg were identified. These values were found at the end of the hypotensive period respectively; 41.5, 54.0 and 35.3 mmHg. On the other hand, the average pre-test heart rate and respiratory rate were determined as 64.3 and 15.6 respectively, while the same value was found as 102.2 and 33 at the end of the hypotensive period. At the end of the hypotensive period, the average number of aquariums, the hematocrit values and the hemoglobin levels declined clearly compared to the pre-test values. At the end of the hypotensive period, apH, vpH, aHC03, vHC03, ap CO2 at CO2 vtCO2 arterial and venous oxygen saturation, arterial and venous oxygen micrates fell. On the other hand, at the end of the hypotensive period, the arterial and venous base excess fell clearly.
