The authors recommend reference values of blood gas, co-oximetry and acid-base balances in arterial blood of normal people (n=53) by using ABL-520 of radiometer Copenhagen.

The site of operation is one of the most significant factors affecting the degree of decreased respiratory function and arterial hypoxemia in the postoperative period. To elucidate the relationship between the site of operation and the postoperative hypoxemia, the authors have performed pre-and post-operative arterial blood gas analysises on the 1st POD through the 4th POD on 30 subjects. The experiment was performed on 3 groups, each of which consisted of 10 subjects; an upper abdominal surgery group, lower abdominal surgery group and extremity surgery group. We have selected only those who have had no preoperative cardiopulmonary problems and excluded those who have developed such complications. The results were as follows; 1) In the upper abdominal surgery group, all postoperative PaO2, values were found to be decreased significantly. 2) In the lower abdominal surgery group, only the 2nd POD PaO2 value was found to be significantly decreased. 3) No demonstrable postoperative change of PaO2, was noted in the extremity surgery group.

A retrospective horizontal cross-sectional study performed on 134 newborn babies with pneumonia from Dec. 2001 to Nov. 2002 at the National Institute of Pediatry. Blood samples were taken from the arteries to evaluates pH, PCO2, PO2, SaO2, HCO3. Results showed: common age > 7 days (73.1%). Boys: 62.7% and girls 37.3%. Pneumonia babies have had commonly mixt acidosis PCO2 in arterial blood < 80 mmHg, pH < 7.29 (63.4%). Almost cases must use oxygene (76.1%), including 12 cases (9%) of assisted ventilation, 4 cases of severe shock must be treated by intensive metabolism

After 2 years studying on 100 patients with acute respiratory failure due to pneumonia from 2002 to 2004, the authors found out there were changes of the blood arterial gases (BAG) values compared with the normal values, as follows: there was a decrease of pH, PaO2, BEecf, PaCO2 decreased at the first phase and increased at next ones; there was increase of AaDO2; slight changes of HCO3. The changes of BAG correlated to levels of acute respiratory failure. The changes returned to normal values among the patients respond to the therapy, and worsen in patients who not responding and going to die.

A retrospective study of the value of blood gas in prognosis of early respiratory failure postoperation was performed on 50 newborns admitted to Children N0 II hospital, HCM city from 2000 to 2002. Examination of blood gas 24 hours before and after operation in 50 newborns. The results as followed: the lower PaCO2 and CRIB score were the good predictor for non respiratory failure in postoperating patients. This study suggested, tests of blood gas before and after operation should be done routinely to predict early respiratory failure for the newborns in NICU

Blood sugar and blood gas analysis changes caused by a 10 hour fast and a 15 hour fast were studied in sixtythree patients. In the 10 hour fast group, mean blood sugar level was 79.58+/-8.77mg/dl compared with the 15 hour fast group was 77.22+/-14.93 mg/dl. There were no remarkable changes on blood gas analysis for both the 10 hour fast group and 15 hour fast group. Neither age nor sex had any significant influence on blood sugar level or blood gas analysis. Thus, in order to make preoperative recommendations as well as to give appropriate intravenous fluids during and following operation, the anesthesiologist must be acquainted with the physiology of fasting.

BACKGROUND: Arterial blood gas analysis are highly susceptible to preanalytic error due to improper method of obtaining or handling the blood sample before analysis. The error in measurement of blood gas analysis are loss of CO2 by exposure to atmospheric air, effect of anticoagulant itself, temperature difference between the experimental subject and the measuring electrode and metabolic change which occur between blood sampling and measurement. METHOD: To study the effect of the delay in estimation of blood gas and drawn blood on values of blood gas partial pressure and pH. Blood sample were divided into 2 groups according to the method of storage, group I stored at 24~25degrees C(room temperature) under anaerobic condition. ;group II stored at 0~4degrees C(refrigerator) under anaerobic condition. The samples were analyzed by time interval through 180 minutes in each group. RESULTS: The result were as follows: 1) PaO2 decreased significantly after 10 mins in group I, whereas it decreased significantly after 20 mins in group II. 2) PaO2 increased significantly after 20 mins in group I, whereas it increased significantly after 120 mins in group II. 3) pH decreased significantly after 60 mins in group I, whereas it decreased significantly after 120 mins in group II. 4) No significant changes of bicarbonate and SaO2 were noted in each group CONCLUSION: From above results, it would be advisable to analyze the sample in a short period of time or to store in a refrigerator when the measuring will be delayed. So we highly recommend that blood gas analysis should be performed as soon as possible after sampling, especially within 10 minutes.
