Answer 1

• sodium lactate
• Na 131
• cl 111
• k - 5
• ca - 2
• lactate - 29

Question 2

hartmanns indications

Answer 2

• provide na and h20 for those who cannot take orally

- to expand cirulating volume in states of impaired tissue eprfusion e.g. shock - can be as fluid challenge

Question 3

MOA hartmanns

Answer 3

• infused lactate metabolised = bicarb
• as compound it contaons similar conc to ECF and is retained there.
• 20% remains in vessels to expand circulating volume

Question 4

why is hartmanns sometimes better than nacl

Answer 4

• lower chloride so less likely to make hyperchloraemic acidosis

Question 5

SE hartmanns

Answer 5

• oedema as too much sodium can enter insterstitium

- overfilled LV - pulmonary oedema

Question 6

Answer 6

• infusions - volume and rate

common - 500ml at 100ml/hr and glucose 5% 2l at 100ml/hr - together this works as maintenance for a day/

Question 7

dose of hartmanns to expand circulating volume

Answer 7

• sodium lactate 500ml/5mins

Question 8

nacl indications

Answer 8

• haemodynamic instability

- expand circulting volume in shock
