Medical Emergencies
Hypoglycaemia
This page discusses Hypoglycaemia, a lowering of the blood sugar most commonly associated with diabetes. This emergency can usually be readily managed by a prepared dental team should a patient have an episode at the dental surgery.
Diabetic Emergencies: Hyperglycaemia and hypoglycaemia - first aid
This video shows first aid outside the surgery. See the text on this page for more detailed management information.

The video provides essential information on how to handle diabetic emergencies, focusing on both hypoglycaemia (low blood sugar) and hyperglycaemia (high blood sugar). It begins by explaining diabetes as a long-term condition characterised by the body's inability to produce sufficient insulin, which can lead to severe fluctuations in blood sugar levels requiring medical intervention.
Hypoglycaemia occurs when blood sugar levels drop too low, often due to an imbalance between insulin and glucose, missed meals, excessive exercise, or as a rare result of binge drinking. Symptoms include weakness, confusion, sweating, and a rapid pulse. Individuals with diabetes may recognise these symptoms and carry a blood testing kit but can also become unresponsive if not treated timely. The video emphasises the importance of checking responsiveness and prepares viewers for the step to take in the event of unresponsiveness.
For immediate care of someone experiencing hypoglycaemia, the video suggests sitting the person down and providing them with sugary foods or drinks, such as fruit juice or jelly babies. If the individual recovers quickly, they should be allowed to rest, and their blood sugar levels can be monitored with a personal testing kit. However, if their condition does not improve, it advises calling emergency services.
In contrast, hyperglycaemia is highlighted as high blood sugar levels that require urgent attention. The video advises calling emergency services without attempting to give food or drink if the person is unresponsive, stressing the need to keep checking their level of responsiveness.
Overall, this video serves as a vital resource to guide dental professionals and members of the dental team on recognising and responding to diabetic emergencies effectively, promoting safety and preparedness in their practice.
The video below discusses and demonstrates Glucagon injection, for when a patient is unconscious due to hypoglycaemia. Note that a patient can feel nauseous after glucagon, so keep them in the recovery position while they come round. Delay giving sugar orally for about half an hour.

In this video, Sarah, a certified diabetes educator, provides a step-by-step demonstration on how to use a glucagon emergency kit for treating severe hypoglycaemia. She begins by explaining what glucagon is and when it should be administered: specifically, it is used when a person is unable to consume food or fluids due to low blood sugar, and it is typically given by someone who witnesses the hypoglycaemic event.
Sarah walks through the process of retrieving and opening the glucagon kit. Inside, there are two components: a vial containing powdered medication and a syringe filled with liquid. She instructs viewers to carefully mix the contents by injecting the liquid into the vial, swirling it until the medication is clear, and then drawing the liquid back into the syringe.
Next, Sarah demonstrates the proper injection technique. She emphasises that the syringe should be held like a dart, and the glucagon can be injected into areas where insulin is typically administered, such as the abdomen, thighs, arms, or buttocks. It is important to inject at a 90-degree angle and ensure that the entire dose is administered. After the injection, the individual should be placed on their side due to potential nausea and vomiting that glucagon can induce.
Sarah notes that the person should start to regain consciousness and awareness within 15 minutes. If there is no response, it's very important to call emergency services. Once the individual is alert enough to swallow, they should be given a source of carbohydrates to treat the hypoglycaemia, such as glucose tablets, fruit juice, or sugar-sweetened soda. She advises rechecking the blood sugar level after 15 minutes and continuing to monitor it every 30 to 60 minutes for the next few hours. If difficulties in maintaining blood glucose levels arise, emergency assistance should be sought.

Hypoglycaemia is literally “low blood sugar”. Hypoglycaemia officially occurs when the blood glucose goes below 3 mmol / litre. more…
Who gets it?
Hypoglycaemia is most likely to occur in patients with diabetes. Lack of natural insulin in these patients causes the blood sugar to rise, and this is treated with self-administered insulin injections, or oral hypoglycaemic tablets.
Hypoglycaemia occurs when insulin has been administered but not enough food has been taken (or too much insulin is administered).
Signs & Symptoms
Depending on the severity, the patient may show
Sweating, clamminess
Trembling
Poor concentration, slurred speech
Aggression
Fitting
Unconsciousness
Diagnosis
Diagnosis is confirmed with an automated blood glucose measurement device. If below 3.0 mmol per litre, the diagnosis is confirmed. (However, some people may have symptoms of hypoglycaemia above this level.) It is a recommendation of the UK Resuscitation Council that every dental practice has this device, as the symptoms of hypoglycaemia are easily confused with other forms of collapse.
Precautions
If a patient is known to have diabetes, ensure they have eaten normally, and taken their normal dose of insulin or oral medication, before any dental treatment.
Management
If the patient is conscious and cooperative, give them oral glucose to take. This can be in the form of sugar, a sugary drink, glucose tablets, or glucose gel.
If the patient is unable to swallow safely, losing consciousness, or uncooperative, consider either buccal glucose gel, or Intramuscular Glucagon injection.
Glucagon IM dose:
1mg in adults and children over 8 years or above 25kg weight.
0.5 mg if under 8 years, or under 25kg.
If Glucagon is given, it may take up to 10 minutes for recovery. When recovered, the patient must take some oral glucose, as the effects of glucagon are very temporary.
If the patient becomes unconscious, follow the procedure for unconscious patients (i.e. check for Signs Of Life, and start CPR if appropriate)
