The Bromcresol purple modified (BCPm) method for testing albumin (Alb) is superior to the Bromcresol green (BPG) method. The Alb in 592 specimens including cases administered hypertonic albumin products (hHSA) was measured using both methods. A multiple regression analysis including the A/G ratio showed r=0.98, and the BCG value varied more as the A/G ratio decreased, with a higher average value of 0.3 g/d
l than that of BCPm. There was no difference in the average Alb value for both groups prior to administration with a BCG value of 2.0 g/d
l converted to a BCPm value, and the hHSA dosage did not increase during the BCPm period. The average Alb value (BCPm) prior to administration during the 25% and 20% hHSA dosage period (102 cases and 113 cases, respectively) was 2.0 g/d
l, with no substantial difference between the two, and the amount used was significantly less during the 20% stage (p<0.01). Comparing the groups based on the value (g/d
l) prior to administration (group I: 1.2 to 1.6 [82 cases], group II: 1.7 to 2.1 [178 cases], and group III: 2.2 to 2.7 [118 cases]), there were no differences in the average value, median value, or IQR of the average number of days of initial successive administration within three days, with the average dosage showing significantly less in lower Alb values (<0.05). Although the overall mortality rate within one month was significantly higher in the cases with a lower Alb value prior to administration (p=0.03), there was no difference in the dosage between the death and survival group. During the investigation (April 2008 to March 2011), the HSA/RCC ratio was less than 2, the average Alb value prior to administration was 2.0 g g/d
l, with more than 60% of all cases having a value of less than 2.2 g/d
l. The amount of hHSA used for each case decreased from the initial dose of 67.2 to 37.9 g, but increased to 56.4 g in 2010, suggesting difficulty in warning clinicians when the Alb value prior to administration is 2.5 g/d
l or more. The amount used may therefore be suppressed by setting the value to less than 2.2 g/d
l prior to administration, continuing to use 20% hHSA, and evaluating all cases two days following administration, as well as by regularly recording the administration objective and effect in the medical records.
