Anaphylactic Shock

26 July 2024

Anaphylactic shock is a severe allergic reaction affecting the whole body.

Developing Anaphylactic Shock

The anaphylactic shock may develop within seconds or minutes of contact with a trigger and is potentially fatal. In an anaphylactic reaction, chemicals are released into the blood that widen (dilate) blood vessels. For this reason blood pressure will fall and air passages narrow (constrict), resulting in breathing difficulties. In addition, the tongue and throat can swell, obstructing the airway. The amount of oxygen reaching the vital organs can be severely reduced causing hypoxia.

Common Triggers of Anaphylactic Shock

Common triggers of anaphylactic shock include food (such as nuts, shellfish and eggs), wasp and bee stings, latex, certain medications, etc. In the event that a person develops an anaphylactic shock, an emergency treatment with an injection of adrenaline will be required.

It can sometimes be difficult to distinguish anaphylaxis from asthma, fainting, and panic attacks. Asthma however typically does not entail itching or gastrointestinal symptoms, fainting presents with pallor rather than a rash, and a panic attack may have flushing but does not have hives.

Anaphylactic Shock and Food

Many foods can trigger anaphylaxis. This may occur after the first known ingestion. Common triggering foods vary around the world due to cultural cuisine. For example, in Western cultures, ingestion of or exposure to peanuts, wheat, nuts, certain types of seafood like shellfish, milk, fruit and eggs are the most prevalent causes. On the other hand, sesame is common in the Middle East, while rice and chickpeas are frequently encountered as sources of anaphylaxis in Asia. Severe cases are usually caused by ingesting the allergen, However, some people experience a severe reaction upon contact. On the positive side, children can outgrow their allergies. By age 16, 80% of children with anaphylaxis to milk or eggs and 20% who experience isolated anaphylaxis to peanuts can tolerate these foods. However, any type of alcohol, even in small amounts, can trigger anaphylaxis in people with Aspirin-exacerbated respiratory disease.

To educate about common food allergens, eLearn Safety has developed a fully online Management of Food Allergens course. The course is designed to introduce participants to understanding food allergens and management of associated risks. Furthermore, after completing the course, participants will be able to understand their requirements under Irish food safety legislation as well as following best work practices.

What to do if someone Suffers Anaphylactic Shock

In case someone is developing anaphylactic shock:

Call 999/112 for emergency assistance. Specifically, tell the ambulance dispatcher that you suspect anaphylaxis.
If the casualty has an auto-injector of adrenaline, help them to use it. If they are unable to administer it, and only if you are trained to use it, apply the injector as trained to do so.
Help the casualty to sit up in the position that best relieves any breathing difficulty. If they become pale with a weak pulse, help them to lie down with legs raised and treat for shock.
Monitor and record vital signs; breathing, pulse and level of response, while waiting for help to arrive. Repeated doses of adrenaline can be given at five-minute intervals if there is no improvement or the symptoms return.

How to Recognise Anaphylactic Shock

Development of anaphylactic shock might have features of allergy:

Red, itchy rash or raised areas of skin (weals).
Red itchy, watery eyes.
Swelling of hands, feet and/or face.
Abdominal pain, vomiting and diarrhoea.

In addition, the following signs might be present:

Difficulty breathing, ranging from a tight chest to severe difficulty, causing the casualty to wheeze and gasp for air.
Pale or flushed skin.
Visible swelling of tongue and throat with puffiness around the eyes.
Feeling of terror.
Confusion and agitation.
Signs of shock, leading to collapse and loss of consciousness.

Remember, the aim of helping someone in anaphylactic shock is to ease their breathing. In addition, a shock treatment might be required. In the event that the patient’s condition is deteriorating, an urgent transport to the hospital might be required. Unfortunately, anaphylactic shock can develop rapidly and patients’ health might degrade even faster, ultimately resulting in fatality.

Online Health and Safety Training

Proactive Health and Safety training is critical to ensure a safe workplace. An effective training program can reduce the number of worker injuries and deaths. It can also reduce instances of property damage, legal liability, illnesses, and missed time from work.

Health and Safety training helps establish a culture in which employees themselves help promote proper safety procedures while on the job. It is important that new employees be properly trained and embrace the importance of workplace safety. The role of training in developing and maintaining effective hazard control activities is a proven and successful method of intervention.

This is why we have established Myelearnsafety school. We pride ourselves in how we guide, support and mentor our students. They receive support throughout their learning experience and into their working lives. Our staff have extensive training experience and also have many years industry experience. We understand the challenges that exist within Environmental and Occupational Health and Safety. Our priority is to ensure that all learners are fully prepared to differentiate themselves in the workplace after completing our Health and Safety courses.

Myelearnsafety offers fully online Health and Safety courses.
