What exactly is Entonox?

Entonox is a pain killing/relieving gas made up of 50% Nitrous Oxide & 50% Oxygen. It’s a very effective analgesic agent with rapid onset & offset characteristics.

Nitrous oxide was discovered in the mid-1700s. Its was first used in America to reduce the pain of tooth extraction & was introduced to Europe in 1867.

Studies show 20-30% nitrous oxide has a comparable analgesic effect to 15mg of sub cut morphine. 50% nitrous oxide (Entonox) was equivalent to 100mgs of pethidine. (Chapman et al, The analgesic effects of low concentrations of Nitrous Oxide compared in humans with morphine sulphate).

When we use Entonox

You should consider using entonox for pain relief after traumatic injuries to your players. You can use it prior to splinting a suspected fracture or painful soft tissue injury in adults & children.

Entonox is a self-administered, inhaled analgesic agent indicated for moderate to severe pain.

Why we use Entonox in Sport

Traumatic sports injuries occur in all sport from grassroot to professional levels.

Your club may be well equipped to deal with these injuries, but not all clubs have access to the appropriate equipment or training. This can leave your players at risk and in pain while waiting for the emergency services to arrive.
