Talk:Saline (medicine)

message: can i know whether  there will be any difference in salines used in india and usa
: depends on where the saline is bought. ie. saline in hospitals will usually have the same constituents, however if you buy saline from a shop, it depends on what salt is used and what the constituents are (dextrose etc.)C3045051 04:06, 31 August 2006 (UTC)

message: In Bøyum A.; Fjerdingstad H.B; Martinsen  I.; Lea T. and Løvhaug D., Separation of human lymphocytes from citrated blood by density gradient (NycoPrep) centrifugation: Monocyte depletion depending upon activation of membrane potassium channels, Scandinavian Journal of Immunology (2002) vol. 56, 76-84, Arne Bøyum uses the formula 
 d = 0.9977 + 0.7 * x /100
for calculating the density of an NaCl solution at 22°C, with which I get 1.004 , not 1.009, for 0.9% saline at 22°C. Bøyum is the person behind Ficoll separation of lymphocytes  and other cell separation techniques, such as Nycodenz  for monocyttes, and thus a person unlikely to get this wrong. There is a reference for the formula in the paper, but to another Bøyum paper that I didn't get hold of. --NorwegianBlue talk 18:26, 13 October 2009 (UTC)

thread_title:  Density of 0.9% Saline 

message: Let's explain the relationship between the 0.9 and 9 figures in the text, if we are showing calculations for other units of concentration as well. I want to explain why a NaCl solution with 0.9% w/v concentration contains 9 grams of NaCl in 1 litre of pure water. This is very simple, yet because there are other basic calculations there too, it has a place after the statement "The solution is 9 grams of sodium chloride (NaCl) dissolved in 1 liter of water". So I suggest to include this after: ", which is equivalent to 0.9 % g / 100mL weight/volume concentration."  
(Checking this: % w/v is a designation for the unit g / 100mL => 0.9 % weight/volume is the same as saying 0.9 g NaCl / 100 milli-liter water, which is equivalent to 9 g NaCl / 1 liter.)

message: I can't for the life of me parse any logical meaning out of this sentence:  "In medicine, saline (also saline solution) is a general phrase referring to a sterile solution of sodium chloride (NaCl, more commonly known as table salt) in water, but is only sterile when it is to be placed parenterally (such as intravenously); otherwise, a saline solution is a salt water solution."  Is this saying that the medical term "saline" only refers to a sterile solution of NaCl, whereas a non-sterile solution is referred to as "salt water"? I don't think that's factually true. Or, is it supposed to say that saline is only medically required to be sterile for certain applications but not others? Cleaning contact lenses is certainly not a parenteral use, so the sentence contradicts the next one on that point. I would just edit this to say what I think it's supposed to mean, but since this is a high importance pharmacology article it seems like it would be best for the question to be resolved definitively.

message: If I understand the term correctly, there is no such thing as a mol of a mixture. Saline is a mixture of two compounds (H2O and NaCl), thus it doesn't have a molar mass. I guess it could have a "mol of the relevant molecules at the specified ratio" and a mass thereof, but that doesn't sound right. Please someone correct me if I've got this wrong, or delete the molar mass value in the data box.

message: This distinction is buried in the article, but it needs to be stated more explicitly.
One shouldn't need to dig so diligently in a general knowledge article to find that the term used in medicine differs in its meaning from that found in standard chemistry texts.
If someone tried to make "normal" saline based on what they learned in chemistry class, the concentration of salt in their mixture would differ greatly from the medical meaning. -71.166.100.197 (talk) 01:34, 20 May 2018 (UTC)
