手術前 NPO 手術後 減壓引流管 Decompression - NG decompression  pressure:? - J-P drain - Hemovac drain 引流管 - Foley-sump drain:一般不用負壓引流,採free drainage     臨床經驗,負壓引流無特別情況, 術後照護重點: 1. 適當引流及腸胃道減壓 2. 營養建立:需長期靜脈營養? 七天以上無法給予腸胃道。                         PPNLP\PPNNP\TPN

[Phsiology] 溶液滲透度osmolaluty & osmolarity

Osmolarity is a measure of the osmoles of solute per liter of solution, while the osmolality is a measure of the osmoles of solute per kilogram of solvent . from http://en.wikipedia.org/wiki/Osmolarity Plasma osmolality Plasma osmolality is a measure of the concentration of substances such as sodium , chloride , potassium , urea , glucose , and other ions in human blood . It is calculated as the osmoles of solute per kilogram of solvent. Normal osmolality in plasma is about 280 - 303 milli-osmoles per kilogram. It is affected by changes in water content. To calculate plasma osmolarity (osmolality) use the following equation: P osm = 2[Na + ] + [Glucose]/18 + [ BUN ]/2.8 The above equation holds true if the glucose & ureas blood chemistry units are given as: mg/dL. If the units are given as: mmol/l; then the calculated osmolality is given by: P .OSM = 2[NA] + 2[K+] + [Urea] + [Glucose] Osmolality can be measured on an analytical instrument called an Osmometer....
