[edit] can

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)
Medical saline solutions for IV use are likely exactly the same in USA and India. alteripse 03:04, 22 December 2006 (UTC)

[edit] Saline's preperties as a catalyst to healing

there should be a section on why and how this works Rtcpenguin 22:06, 21 December 2006 (UTC)

Not sure what you mean. If you give us a link to some evidence as to how it is used and that it does work, and then we will see what we can do with the why and how it works. alteripse 03:04, 22 December 2006 (UTC)

[edit] Role in Lap-Band

Is it worth mentioning that saline is the key ingedient to the functionality of Lap-band?? -MrBucket 17:37, 27 February 2007 (UTC)

I don't think so. In what sense is it a key ingredient? --Una Smith (talk) 02:31, 1 May 2008 (UTC)

[edit] pH of saline

Definitelyphazed 18:56, 19 October 2007 (UTC)Why are bags of saline labelled that they are pH5.5 or pH 5.0?

If they do indeed just contain NaCl in pure water, then at 298K the pH should be 7.0.

For Na+ you need to take the pK (dissociation constant) of NaOH into account, and for Cl- the pK of HCl. The ionisated sodium kation in water acts as a strong acid, the chloride anion as a weak base. Thus the resulting pH is 5.XX. Wkr, --Paunaro 17:10, 22 October 2007 (UTC)

I know nothing about standard saline, but I believe Paunaro is incorrect. When pure NaCl is dissolved in pure water the solution will be at pH 7 - NaOH is a strong base and HCl a strong acid (ie both completely dissociate). However, pure water left in air will become acidic due to the carbon dioxide in the atmosphere. 155.198.213.89 12:39, 24 October 2007 (UTC)

OSMOLALITY OF NORMAL SALINE. If the osmotic coefficient of NaCl is 93%, then shouldn't the osmolality of normal saline be 286 (93% x 2 x 154), not "300" (as the article states)? —Preceding unsigned comment added by 152.130.6.136 (talk) 03:46, 11 April 2008 (UTC)

[edit] Photo

Surely someone can get a quick picture of an IV bag full of saline? This could be useful on so many articles (anything that involves an IV infusion, for example). WhatamIdoing (talk) 01:45, 29 April 2008 (UTC)
