Week 2 Flashcards
Mechanism of injury (MOI)
How an injury happened
Sources of MOI
Trauma
Overuse
Trauma
From an external force on the body
Overuse
Repetitive strain on a tissue
Onset of MOI
Acute/traumatic
Insidious
Acute/traumatic
Sudden onset
Insidious
Gradual and often of unknown origin
Signs
Something you see
Symptoms
Something the athlete feels/describes
Examples of signs
- bruising
- swelling
- heat/cold
- spasm/guarding
- sweating
- shivering
- vomiting
Examples of symptoms
- pain
- tingling
- numbness
- burning
- tight
- pressure
- nausea
Pain
- no every experience is the same
- comes with fear and shock
- imp to reassure
Psychological affects of injuries
- anger
- fear
- denial
- sadness
- catastrophizing
- regret
Things to consider for psychology of injuries and performance
- coping strategies
- support at home
- access to care
- professional support
- team/coach support
How can we help with the psychology of injuries?
- listen
- reassure
- know when to refer
- educate
- coach/player/family/friend support
- mindful and sequential return to play
- keep them part of the team
Types of skin wounds
- lacerations
- abrasions
- punctures
- contusions
- blisters
Laceration
Slice in tissues
Management of lacerations
- Control bleeding
- Clean he wound
- Steri-strips
Step 1: Control the bleeding
- PPE (gloves)
- Pressure
- Elevation
Pressure to control bleeding
- “all gauze sponges” ie. non-sterile loose gauze
- add extra layer of gauze as needed (don’t remove previous layer)
- conforming stretch gauze bandage
Step 2: Clean the wound
- soap and water
- cinder suds (lifts dirt and debris)
Step 3: Steri-strips field coverage considerations
- dry the area around the laceration
- adhesive spray via Q-tip
- rub Q-tip on either side of laceration where steri-strips will be applied
When do we send for stitches?
- only done effectively within 24hrs of injury
- deep wounds affecting more then just skin
- unable to stop the bleeding
- wound is to the face
- wound is across the joint
Minor cuts and abrasions
- superficial layers of skin
- for return to play: non-stick gauze and cover roll
Punctures
- if object is still in, leave it in
- pad around it with gauze rolls
- send for medical attention
Contusions
- bleeding under skin from blunt trauma
Deep contusions
- need proper management to avoid myositis ossificans
- no deep tissue massage
- effleurage or lymph drainage
- ice
- protective padding (donut pad)
How can contusions be supervised in clinic?
- ultrasound (pulsed setting)
- interferential current (IFC)
Blister prevention
- skin lube over areas of friction
Blister treatment
- if broken, clean well
- second-skin
- coverroll/hypafix
When do we seek medical attention?
- unable to control bleeding
- wound is dirty and unable to be cleaned
- deep wound or puncture
- object os still impaled
- changes in sensation
- wound is from human/animal bite
- wound is from rusty object
Cartilage and meniscus healing
- limited capacity to heal
- little or no direct blood supply
Ligament healing
- during repair phase, collagen or connective tissue fibres lay down randomly
- gradually scar is formed
- over following months collagen fibres align in response to joint stress/strain
Skeletal muscle healing
- regeneration of new myofibers is minimal
- healing and repair follows the same process of random collagen alignment and develops tensile strength in response to stress/strain
Healing of nerves
- regeneration can take place very slowly (3-4mm/day)
- peripheral nerves regenerate better than central nervous system
Phases of wound healing
- Hemostasis
- Inflammation
- Repair and regeneration
- Remodelling
Hemostasis
Process leading to cessation of bleeding
