RESUMO
Objective To establish a quality control model ensuring good stability and compatibility of manually compounded total nutrient admixtures (TNA). Methods A parenteral nutrition medication order entry system was establish for standardizing nutritional medication usage and supporting physician's TNA prescribing. TNA medication orders were reviewed by pharmacists for validating the stability and compatibility. TNAs were compounded by pharmacists in a standard way following "four factors of sterile compounding". The goal of quality control was achieved by establishment of the preliminary standard. Results The quality of manually compounded total nutrient admixtures achieved the goal since pharmacy intravenous admixture service (PIVAS) started on 2003. Conclusions The quality of TNA is well assured while manually compounded by pharmacists in PIVAS.

RESUMO
Objective To compale the physical and chemical parameters of three market available medi-an/long chain fat emulsions.Methods The quality properties were determined and compared according to the fat emulsion injection quality standards in the Chinese Pharmacopeia Convention,the United States Pharmacopeia Con-vention,and the National Standard.Results Products A:the pH value was between 8.2-8.3;the particles with a size larger than 1 μm were 1.23%-1.53% and no particles were larger than 5 μm;the mean particle size was 0.246-0.256μm;the acid value was 0.2;the peroxide and methoxyl aniline values were 0 and 0.9-1.4;the he-molysis phosphatide was 0.6-0.9 g/L. The contents of fat,glycerin,and triglycerides were more than 97% of the labeled amounts;the content of phosphorus was 0.46-0.49 g/L. Products B:the pH value was between 8.2;the partocles with a size larger than 1 μm were 0.81%-1.62% and no particles were larger than 5 μm;the mean parti-cle size was 0.239-0.241 μm;the acid value was 0.4-0.5;the peroxide and methoxyl aniline values were 0 and 0.8-1.4;the hemolysis phosphatide was 0.2-0.6 g/L. The contents of fat,glycerin,and triglycerides were more than 94% of the labeled amounts;the content of phosphorus was 0.42 g/L. Products C:the pH value was between 7.7-8.1;the particles with a size larger than 1 μm were 0.42%-0.86% and no particles were larger than 5 μm;the mean particle size was 0.249-0.262 μm;the acid value was 0.3-0.4;the peroxide and methoxyl aniline values were 0 and 1.8-2.9;the hemolysis phosphatide was 0.5-0.8 g/L. The contents of fat,glycerin,and triglycerides were mole than 96% of the labeled amounts;the content of phosphoms was 0.44-0.46 g/L. Conclusion All properties of the median/long chain fat emulsions produced by the three manufacturers met the National Standard.
