Low BP for age or relative to person's previously recorded values
Do not
Do not remove any object sticking out of a wound
Do not remove any bandages that blood soaks through. Apply another bandage on top and maintain
pressure
Do First
Try to stop visible bleeding
Apply firm direct pressure with gloved hands with or without pad — Figure 2.18
If something in wound — apply pressure to pads above and below or around object
Reduce fractures or dislocations
Infiltrate site with lidocaine (lignocaine) 1% + adrenaline (epinephrine) 1:100,000 (eg scalp wounds) up to 50mL
When bleeding controlled — bandage pad in place, elevate (raise) part and immobilise if needed
If lot of blood has been lost — lie person down

Check
Calculate age-appropriate REWS
Adult — AVPU, RR, O2 sats, pulse, BP, Temp
Child (less than 13 years) — AVPU, respiratory distress, RR, O2 sats, pulse, central capillary refill time, Temp
Weight, BGL
Do
Urgent medical consult if signs of shock — see red flags
Give oxygen to target O2 sats 94–98% OR if moderate/severe COPD — 88–92%
Put in 2 IV cannula, largest possible or gain intraosseous access
Run blood if available otherwise Hartmann's solution or normal saline — adult 500mL, pregnant woman 1L, child 20mL/kg — doses
Reassess for more fluids
Give tranexamic acid if within 3 hours of injury
Adult — tranexamic acid IV — 1g (in 100mL compatible fluid) over 10 minutes THEN 1g (in 1000mL of a compatible fluid) over 8 hours —doses
Child — tranexamic acid IV — 15mg/kg up to 1g over 10 minutes THEN 2mg/kg/h for 8 hours, dilution 500mg in 500mL of compatible fluid and infuse at 2mL/kg/h
(maximum dose 125mg per hour) — doses
Medical consult — send to hospital
On-going care
Monitor for signs of shock — see red flags
Check every 15 minutes
Pulse — consider more IV fluids if pulse more than 100/min (adult). Pain and anxiety
also cause fast pulse
BP — give more IV fluids if systolic BP less than 90mmHg (adult)
If urine output less than 0.5mL/kg/hr — probably needs more fluids
Keep patient warm — aim for normal temp
Bleeding limb
Do
If firm pressure for 10 minutes and elevating limb doesn’t stop bleeding
Put BP cuff on arm/leg above and close to wound, blow up to 30mmHg above systolic
BP — Figure 2.19
Leave for 30 minutes
Let BP cuff down for 2 minutes
Blow up again and leave for another 30 minutes
Repeat until more help arrives
AND/OR
Try to find bleeding point and stop by
Direct pressure and infiltration of lidocaine (lignocaine) + adrenaline (epinephrine) 1:100,000 up to 50mL
If this doesn't work and good view of blood vessel — suture or clamp, if skilled (put
clamps on carefully or nerves that run beside blood vessels may be permanently damaged)
Figure 2.19
If torrential bleeding that still hasn't stopped
Medical consult — about further management
Put on tourniquet, several centimetres proximal (above) to wound — do not remove
Record time applied
Send to hospital urgently
Best chance to save limb if arrive within 4 hours of putting on tourniquet
If on warfarin give vitamin K
Give tranexamic acid 1g in 0.9% sodium chloride (100mL) over 10 minutes if not already administered within
3 hours of injury, then 1g in 1000mL over 8 hours
