Right, I am daoing homework for something more fulfilling(:
Bone, Joint and Muscle Injuries Fracture:
- A break or crack in a bone
- Category:
- Closed Fracture: Where skin is not broken (OUCH!)
Open Fracture: Where the skin is broken (DOUBLE OUCH! WITH GROSS FACTOR)
- Types of Fracture:
- Simple Fracture: Only the bone is broken/cracked
- Compound Fracture: Bone and tissue damage
- Complicated Fracture: Bone, tissue and organ damage
- Signs and Symptoms:
- Deformity, swelling and bruising on fracture site
- Pain and difficulty in moving
- Shortening, bending or twisting of limb
- Coarse grating sound heard at bone ends
- Loss of function
- An open wound in case of open fracture
- First Aid Treatment
- Instruct casualty not to move
- Check for bleeding
- Check for shock (life threatening condition where body does not get enough blood flow, can cause multiple organ damage and death)
- Immobilize and support the fracture
- Use bandages or splints or a combination of both
- Monitor circulation (observing capillary refill at fingers and discoloration if any) and pulse
- Arrange for immediate removal to hospital
Dislocation
- Joint: Junction where one bone meets another. Joints are joined by ligaments
- A Dislocated Joint is an injury where the bones are partially or completely pulled out of position
- Causes:
- Violent Muscle Contractions
- Violent Twisting
- Signs and Symptoms:
- Pain
- Limited Movement
- Shortening, bending or twisting of dislocated area
- First Aid Treatment:
- Immobilize affected area
- Supported affected area after immobilization
- Check for pulse and respiration
- Check for circulation at fingers and toes every 10 minutes
- Precautions:
- Do not reposition dislocated bone into socket!
- Do not move affected part before immobilization
- Do not allow casualty to eat or drink
Sprains and Strains
- Definitions
- A sprain is a joint injury in which some of the fibres of a supporting ligament are ruptured but the continuity of the ligament remains
- A strain is an overstretching of some part of the musculature
- No dislocation is involved in sprains and strains
- Signs and Symptoms:
- Limited movement in the joints
- Pain and tenderness
- Swelling and bruising
- First Aid Treatment
- RICE
- Rest
- Ice for less than 10 minutes
- Compression
- Elevation
Heatstroke
- Definition:
- Failure of the body's biological thermostat (hypothalamus)
- LIFE THREATENING EMERGENCY
- Causes:
- High fever
- Prolonged exposure to heat
- Signs and Symptoms:
- Headache, dizziness and discomfort
- Restlessness and confusion
- Hot, flushed, dry skin
- Decrease in level of response
- Bounding oulse
- Body temperature above 40 degree Celsius
- First Aid Treatment:
- Transport casualty to cooler location
- Remove as much clothing as possible
- Wrap casualty in cold wet sheet, keep sheet moist until body temperature falls to 38 degree Celsius
- One temperature lowers to 38 degree Celsius, replace wet sheet with dry one
- Monitor vital signs (pulse, respiration, response)
- Repeat procedure should temperature rise
Heat Exhaustion
- Definition:
- Loss of salt and water from the body due to excessive sweating
- More common than heatstroke
- First Aid Objective:
- Replace lost body fluids and salt
- Decrease temperature if necessary
- Signs and Symptoms:
- Headache, dizziness and confusion
- Nausea, loss of appetite
- Hot, flushed, dry skin
- Sweating with pale clammy skin
- Cramps on the legs, arms and/or abdominal wall
- Rapid, weakening pulse and breathing
- First Aid Treatment:
- Have victim drink fluids
- Have victim lie down with feet elevated to allow blood flow to brain
- Use cold compresses and a fan to lower body temperature
Another major cause of concern:
Hyperventilation or Over-breathing
- Definition:
Excessive breathing leading to increase levels of oxygen that causes drastic chemical changes within body
- Causes:
- Excitement
- Hysteria
- Other random emotions and outbursts
- Signs and Symptoms:
- Normal or pink skin colour
- Rapid or deep breathing
- Attention seeking behaviour !
- Giddiness
- Cramps in hands and feet
- First Aid Treatment:
- Firm reassurance
- Encourage casualty to take slow regular breaths
- Instruct casualty to breath in and out a paper bag until symptoms disappear
This is a
serious cause of concern!
