Study Notes
Basic Life Support (BLS)
- Refers to care given initially by first responders during cardiac arrest or respiratory distress.
- Immediate, fundamental action. Early BLS can restart a heart. Delays are fatal.
- Cardiac arrest:
- Unresponsive, absent or abnormal breathing (labored breathing, agonal breathing).
- Seizure-like movements at initial stage.
- Heart stops beating; blood circulation stops.
- BLS Steps:
- Check for a response.
- Check for abnormal or absent breathing.
- Call emergency services.
- Start CPR and rescue breaths.
- After AED arrives, switch to AED use.
- AED:
- Detects abnormal heart rhythms.
- Delivers electrical shocks if needed.
- Clear instructions.
- CPR:
- Main priority: Chest compressions (lower half of sternum, 5-6 cm deep, 100-120/min) allowing full recoil of the chest.
- 30:2 compression-to-breath ratio.
- Continue until help arrives or becomes exhausted.
Bleeding
- Direct pressure is the initial response to control bleeding.
- Apply direct pressure to the bleeding site with clean cloth, tissue, or gauze.
- Maintain pressure until bleeding stops or help arrives.
- For wounds on arms or legs, elevate the limb above the heart.
- Deep wounds, large blood vessels, neck, or torso injuries may need special consideration.
- Avoid removing embedded objects. Instead, apply pressure around the object.
Embedded Objects
- Do not remove objects.
- Apply pressure around the object (above and below).
Amputations and Trauma
- Do not use tourniquets in crush injuries or amputations.
- Tourniquets are for life-threatening bleeding.
- Wrap the tourniquet above the wound and constrict blood flow.
- Keep the bleeding site and heart a few inches apart.
- Do not remove the tourniquet until medical help arrives.
- Note potential complications.
Wound Packing
- Wash hands. Remove bandages.
- Clean the wound with saline and sterile gauze or padding.
- Push packing material into wound areas.
- Cover and secure the wound.
Homeostatic Agents
- Substances that promote blood clotting and control bleeding.
- Topical hemostatic agents are applied directly to the bleeding.
- Systemic hemostatic agents are taken orally or injected to promote blood clotting systemically.
- Example: Desmopressin, Factor concentrates, Tranexamic acid.
Wound Healing and Sutures
- Wound healing phases: Lag, Fibroplasia, and Maturation.
- Equipment for wound closure includes staplers, sutures, and instruments for wound preparation.
- Patient preparation: Informed consent, assessment of the wound.
- Debridement removes dead tissue.
- Principles for wound closure: Minimizing tension, closing with minimal trauma, eliminating dead space.
- Sutures include Simple interrupted, Simple running, Deep to inverted knot, Vertical mattress, Horizontal, and Subcuticular.
- Wound healing complications include infection, pain, and bleeding.
