In Australia, When Should You Use the Pressure Immobilisation Technique?

Introduction:

Australia is home to a variety of venomous creatures, including snakes, sea snakes, cone shells, funnel-web spiders, and the blue-ringed octopus. While encounters with these creatures are relatively rare, it is crucial for residents and visitors alike to be aware of first aid measures incase of envenomation. One such technique recommended in specific situations is the Pressure Immobilisation Technique (PIT). In this article, we will explore when and how to use PIT, focusing on the guidelines provided by ANZCOR(Australian and New Zealand Committee on Resuscitation) and the contributions of Professor Struan Sutherland.

Understanding the Threats:

Snakes:

Australia is home to some of the world's most venomous snakes, including the Inland Taipan and the Coastal Taipan. Encounters with snakes can lead to potentially life-threatening bites, necessitating immediate first aid.

Sea Snakes:

Australia's coastal waters are inhabited by various species of sea snakes, some of which are venomous. Bites from these creatures can result in envenomation, requiring prompt attention.

Cone Shells:

Cone shells, found in marine environments, are known for their potent venom. Stings from cone shells can lead to severe symptoms, emphasizing the need for quick and appropriate first aid.

Funnel-Web Spiders:

Found predominantly on the eastern coast of Australia, funnel-web spiders are notorious for their toxic bites. The venom can cause serious health issues, especially in children and the elderly.

Blue-Ringed Octopus:

Despite their small size, blue-ringed octopuses possess venom that can be fatal. Quick action is essential in the event of a bite, as symptoms can progress rapidly.

The Aim of Pressure Immobilisation Technique:

The Pressure Immobilisation Technique is a first aid method designed to slow the spread of venom through the lymphatic system. The primary aim is to restrict the movement of venom from the bite site into the bloodstream. This technique is not appropriate for all types of bites or stings but is specifically recommended for creatures such as snakes, where venom travels through the lymphatic system.

How to Use Pressure Immobilisation Technique:

Ensure Safety:

Before attempting any first aid, ensure the safety of yourself and others. Move away from the source of danger and call 000.

Apply Pressure Bandage:

Starting from the extremities (fingers or toes) and working towards the body, apply a firm pressure bandage. The bandage should be tight but not to the extent that it cuts off blood circulation.

Immobilise the Entire Limb:

Extend the bandage as far up the limb as possible, covering the entire bitten area. This helps to slow the movement of venom through the lymphatic system.

Mark the Bite Site:

If possible, mark the bite site on the bandage with the time of the bite. This provides essential information for healthcare professionals.

ANZCOR Guidelines and Professor Struan Sutherland's Contributions:

ANZCOR Guidelines, specifically Guideline 9.4.8 on Envenomation - Pressure Immobilisation Technique, provide detailed instructions on when and how to use PIT in Australia. These guidelines are based on extensive research and expert consensus, including the work of Professor Struan Sutherland.

Professor Struan Sutherland, an Australian pharmacologist, played a crucial role in developing the Pressure Immobilisation Technique. His research laid the foundation for the understanding of snake venom and the efficacy of PIT in slowing its spread.

Conclusion:

Encounters with venomous creatures in Australia can be dangerous, but knowing how to respond with appropriate first aid measures, such as the Pressure Immobilisation Technique, can significantly improve outcomes. By following ANZCOR guidelines and building on the contributions of experts like Professor Struan Sutherland, individuals can be better prepared to handle envenomation incidents and mitigate the potential risks associated with bites and stings.
