3.4.3 – Risk assessment and safety Learning objectives To understand the difference between a strain and a sprain. To be able to explain treatment for a soft tissue injury. To describe joint injuries sustained in sport. To understand the different type of fractures. To understand the terms concussion, dehydration, and hypothermia. First aid First aid and emergency aid are necessary following an injury in sport. Minor and major injuries are treated in different ways. Sports such as badminton are less likely to involve injuries than contact sports. Muscles and injury When exercising there is always a risk of muscle injury. A STRAIN is a soft tissue injury (pulled or overstretched muscle). Treatment: R.I.C.E. (Rest, Ice, Compression, Elevation) Avoidance: Warm up thoroughly. Muscles and injury A SPRAIN is a soft tissue injury (Twisted or wrenched ligament). Sprains occur when ligaments at joints get stretched and torn. i.e. Sprained ankles are very common Severe sprains result in torn ligaments. Treatment: R.I.C.E. (Rest, Ice, Compression, Elevation) Avoidance: Strengthen area using weight training Treatment for soft tissue injuries R Rest the injured part. I Apply Ice to reduce the swelling for 10 minutes (max). Frozen peas work well! C Compress the injury, possibly using a tubigrip bandage. Elevate the part to decrease the blood E supply. Joint Injuries Dislocation – Occurs at a joint. What is a joint? Causes Dislocations are usually caused by a sudden impact to the joint. This usually occurs following a blow or a fall. The bones that meet at that joint becomes dislocated (not connected). Symptoms of a dislocation – How can you tell? A dislocated joint may be: • Visibly out-of-place, discoloured, or mis-shapen • Limited in movement • Swollen or bruised • Intensely painful, especially if you try to use the joint or bear weight on it Soft tissue injuries An open injury means that the skin has been broken – blood usually escapes. Cuts - require immediate attention to stop bleeding and allow the blood to clot. Grazes or abrasions where skin is scraped off the body. Grazes that result from falls can often contain dirt and grit. Bruises Bruises occur when small blood vessels are damaged under the skin. This causes bleeding beneath the skin, leading to swelling and discolouration. Bruises and strains should be treated with ice to reduce the swelling. Tennis Elbow Tennis elbow is an inflammation, soreness, or pain on the outside side of the upper arm near the elbow. Causes: This injury is caused by repetitively twisting the wrist or forearm. The injury is classically associated with tennis playing, hence the name "tennis elbow," but any activity that involves repetitive twisting of the wrist (like using a screwdriver) can also lead to it. Tennis elbow treatment: - R.I.C.E. - Steroid injection Strapping can help prevent the occurrence of tennis elbow Golfer’s Elbow Golfer’s elbow is similar to tennis elbow. The repetitive strain is on the inside of the elbow. Treatment: RICE Fractures A fracture is a break or crack in the bone Bones can break when a direct impact is received (hockey stick striking the shin) or indirect force is produced by a twist or a wrench (a trip or stumble). Fracture Types Closed Fracture The surrounding skin is unbroken. This is also known as a simple fracture. Closed fractures usually occur during rugby and football matches. Open Fracture Close to the fracture, the skin is broken and the bone may protrude through. This can cause complications with infection from germs. Treating Fractures To deal with a major fracture you should keep the casualty still and ring 999. Never move the casualty (unless in danger). Never try to replace a dislocated bone. Reassure the patient Recovery Position Head is supported/ tilted so tongue or vomit doesn’t block airway Support/stability so person doesn’t roll over Safest position for an unconscious person BUT breathing Makes the casualty comfortable, able to breathe and safe from choking When might someone need to be put into a recovery position? What sporting incident? Cardio-Pulmonary Resuscitation (CPR) Mouth to Mouth Ventilation -Seal mouth over mouth and pinch nose. This forms a seal and ensures no air escapes. Provides vital oxygen to the body artificially. - 2 breathes – continue until ambulance arrives, they breathe or too tired Chest compressions - Perform 30 compressions of the chest at the sternum - Know as cardiac massage. The aim is to squeeze the heart so blood pumps through the body Concussion Concussion is a common cause of unconsciousness while playing sport. Concussion occurs when an individual has received a blow to the head. The signs can include disorientation, loss of vision, vomiting, paleness, a racing pulse and shallow breathing. Concussion should be treated at hospital. Dehydration When we exercise, especially in hot conditions, the body loses water as a result of sweating. If the performer does not re-hydrate by drinking lots of water, they may suffer from dehydration. This results in the performer feeling very tired and faint. Hypothermia If a performer’s body temperature falls below 35°C, they begin to suffer from hypothermia. Common symptoms of hypothermia are shivering, paleness, loss of dexterity and erratic behaviour. Summary Questions: Describe the difference between a strain and a sprain. What is concussion? What is a open/closed fracture? How do you treat a soft tissue injury? Describe the signs of hypothermia.
