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: Recent blood gas analyzers offer electrolytes, Hb-derivatives (O2 Hb, HHb, COHb, MetHb and SulfHb), content of total hemoglobin (ctHb), and metabolites (glucose and lactate) as well as conventional blood gas parameters. Evaluation and efficient control of these instruments affect greatly monitoring and therapy of patients. The authors evaluated a recently introduced blood gas analyzer, the Roche OMNI 9 (Roche Diagnostics) for precision, analytic speed, function, features and comparability with other instruments according to NCCLS guidelines to see if it was suitable for the stat analyzer. METHODS: Commercial control materials, AUTO-trol PLUS Level 1, 2, 3 (Roche Diagnostics) were analyzed to evaluate the within-day precision, the between-day precision, and patient samples were used to evaluate comparability with other instruments. RESULTS: The within-day and the between-day precisions of the Roche OMNI 9 showed a very low CV of 0- 3.93% and 0- 3.99%, respectively, in all parameters except the lactate, which had moderate CV values of 7.74% and 5.93% in Level 3 QC material (low concentration). In compari-son with the Bayer instrument, correlation was high in all parameters with the r(2) value ranging from 0.9441 to 0.9901 except for COHb (r(2)=0.4239) and MetHb (r(2)=0.0034) whose concentrations were in the lower level. Glucose (r(2)=0.991), lactate (r(2)=0.9824), and hemoglobin (r(2)=0.9961) showed a rather high correlation. The Roche OMNI 9 could analyze 40 samples of blood gas and 27 samples of full parameter per hour, which was comparable to the Bayer M855. CONCLUSIONS: The Roche OMNI 9 showed high precision and rapid turnaround time for blood gas and in a selection of glucose, lactate and hemoglobin.
