ABSTRACT

NB: commonest cause of ¡Na in hospital is overuse of 5% glucose as fluid replacement.

• Glucose* saline: 1 litre contains mixture of NaCl (30 mmol Na) and glucose (4% 222 mmol). Useful as contains correct proportions of constituents (excluding KCl, which can be added to each bag)

for average daily requirements (see below). Suboptimal long term, as

does not account for individual patient needs (esp if these are far from

average). Also used as ivi in insulin sliding scales (see p. 203).
