WHy on occasions CALLing 999 can be better than just going to A&E.

As the NHS suggest
In some situations such as a heart attack, stroke, or major trauma as examples. “Every second counts with these conditions.” When to call 999 – NHS . Also an ambulance can ensure that you are taken to the correct place such as a stroke centre.

EMERGENCIES

The purpose of this section is to cover some of the common serious conditions divided up by symptoms and signs. If you might have any of these serious conditions then you should act immediately. This is not an exhaustive list so if you are not sure call 111.

CONFUSION

As the NHS points out
“Call 999 for an ambulance if someone suddenly becomes confused. Many of the causes of sudden confusion need assessment and treatment as soon as possible. In some cases, it may be life threatening.”

Also consider confusion after a head injury as a reason to call 999

As the NHS suggests after a head injury
“Symptoms of a subdural haematoma can include:

  • a headache that keeps getting worse
  • feeling and being sick
  • confusion
  • personality changes, such as being unusually aggressive or having rapid mood swings
  • feeling drowsy
  • loss of consciousness

The symptoms can develop soon after a severe head injury (acute subdural haematoma), or very occasionally a few days or weeks after a more minor head injury (subacute or chronic subdural haematoma).”

If you develop the symptoms above any time after a minor head injury, you should also go to your nearest A&E department or call 999 for an ambulance as soon as possible.” Subdural haematoma Subdural haematoma – NHS

SPEECH problems

The NHS points out speech changes which can be found with a stroke or TIA

SKIN CHANGES (INCLUDING SEVERE ALLERGIC REACTION – ANAPHYLAXIS)

As part of some conditions there can be skin changes (changes in colouring, swelling, or rashes) which can indicate with the other symptoms that an urgent assessment at A&E is needed

As the NHS suggests
“Call 999 or go to A&E if:

  • lips, tongue, face or skin suddenly turn blue
    may also have:

    Cyanosis can mean there’s not enough oxygen in your blood and as such can be caused by many serious conditions which can impact on oxygen transport including in the airways, lungs, and heart.

THE MENINGITIS RASH

As Meningitis Now suggests
“People with septicaemia may develop a red rash of tiny ‘pin pricks’, which can develop into purple bruising. This rash does not fade under pressure.”

SKIN CHANGES OF ANAPHYLAXIS (SEVERE ALLERGIC REACTION)

The skin changes of anaphylaxis on their own do not necessarily in themselves indicate a serious condition, it is the combination of the skin changes with the other symptoms of anaphylaxis (such as difficulty swallowing, difficulty in breathing and confusion) which can give the clue to anaphylaxis.

As the Anaphylaxis Campaign suggest the skin changes might include

  • “Widespread flushing of the skin
  • Nettle rash (otherwise known as hives or urticaria)
  • Swelling of the skin (known as angioedema) anywhere on the body (for example, lips, face).”

SKIN CHANGES OF CELLULITIS

In the majority of cases cellulitis is treated just by your GP, but on occasions you should attend A&E. This is when the rash of cellulitis (examples shown in the article from NHS choices) is combined with other symptoms which may suggest sepsis.

  • purple patches on your skin, but this may be less obvious on brown or black skin

  • difficulty breathing, breathlessness or breathing very fast
    They may not have all these symptoms. Sepsis Symptoms of sepsis – NHS 

For more information on sepsis see under Spotting Sepsis.

VOMITING

Vomiting on its own does not necessarily indicate a very serious condition but on occasions when they are combined with other symptoms or signs this can mean attendance at A&E is required.

VOMITING BLOOD (HAEMATEMESIS)

As patient info suggests

DEHYDRATION

As the NHS suggests
“Dehydration means your body loses more fluids than you take in. If it’s not treated, it can get worse and become a serious problem.”

OTHER SERIOUS CONDITIONS WHICH CAN HAVE VOMITING OR FEELING SICK (NAUSEA) AS A SYMPTOM

Importantly it is the other symptoms which indicate a serious condition, so look for these other symptoms.

Vomiting does not necessarily need to be part of the following serious conditions but can be:

BLEEDING

Call 999 if you have severe bleeding that cannot be stopped.

Bleeding in certain situations or when combined with other symptoms or signs may indicate an emergency response is needed and calling 999. If you are not sure call 111. Some important examples include:
