TRANSCRIPT
General objective:At the end of our 30-minute discussion,
the learners will be able to comprehend knowledge about bleeding.
Moreover, the learners will be able to understand the significance of proper management of bleeding in application for their upcoming profession.
Specific Objectives:
After the 30-minute lecture discussion about the subject matter,• the learners will be able to:
– define what bleeding means;– figure out some causes of such;– recognize the classes of hemorrhage;– enumerate the types of bleeding;– differentiate the characteristics of the three (3) types of external
bleeding according to what kind of blood vessel is damaged;– recognize the signs of internal bleeding; – know the operative techniques in bleeding-control; and– be familiarized on what to do when bleeding occurs.
Specific Objectives:• the lecturers will be able to:
– explain what the subject matter is about;– define what bleeding is;– distinguish the difference of the two types of bleeding;– make clear the different classes of hemorrhage;– present the different characteristics of the types of external
bleeding;– impart the knowledge about the treatment and management
when bleeding occurs; – present the operative techniques in controlling bleeding; and– encourage participation by asking some questions during the
lecture proper.
Massive Bleeding/Hemorrhage

What is hemorrhage?
• Hemorrhage is the medical term for bleeding (lost of blood from the body)
•Refers to the amount of bleeding (500cc) in a short time.
Causes of hemorrhage:
• Trauma – blunt or penetrating injury, iatrogenic trauma, surgical procedures.
• Underlying pathology – peptic ulcers, aneurysms, AV malformations, malignancy, uremia, etc.
• Coagulation disorders – e.g hemophilia • Drugs – NSAIDS, warfarin, etc
Classes of hemorrhage:• Class I – up to 15% blood loss - usually, no change in BP, pulse pressure
or respiratory rate - minimal tachycardia may be there
- CRT > 3 seconds ≈ volume loss 10%
• Class II – blood loss 15-30%- tachycardia, tachypnea, decreased pulse
pressure, cold clammy skin, delayed capillary refill, slight anxiety
• Class III – loss of 30-40%-marked tachycardia and tachypnea, decreased systolic BP, oliguria, altered mental status like confusion or agitation-most will require blood transfusion
• Class IV – loss of > 40% blood volume-marked tachycardia, decreased BP (diastolic may be unrecordable), markedly decreased or no urinary output, depressed mental status ( or loss of consciousness) cold and pale skin.- immediately life threatening.
Two types of bleeding:
• Internal Hemorrhage• External hemorrhage
External Bleeding:
• Refers to blood coming from an open wound.• Can be classified into three types according to
blood vessel that is damaged: - an artery, vein or capillary
External Bleeding:
• Bleeding which is visible• Also called revealed hemorrhage• Easy to assess the blood loss and to control
the hemorrhage• E.g hemorrhage due to cut wounds, ruptured
varicose veins, hematemesis
Arterial bleeding:
• Blood spurts (up to several feet) from the wound).
• Is the most serious type of bleeding because a large amount of blood can be lost in a very short period of time.
Venous bleeding:
• Blood from a vein flows steadily or gushes.• Is easier to control than arterial bleeding
• However, bleeding from deep veins can be as massive and as hard to control as arterial bleeding.
Capillary bleeding:
• The most common type of bleeding• Quite often, this type of bleeding will clot and
stop by itself.
Treatment for hemorrhage:
• Urgent treatment required• Resuscitation• Minimize further blood loss
- direct pressure - packing with rolls of wide gauze - elevate affected area - drugs: vasopressin
Internal Bleeding:
• Occurs when damage to an artery or vein allows blood to escape the circulatory system and collect inside the body. The amount of bleeding depends upon the amount of damage to an organ and the blood vessels that supply it, as well as the body's ability to repair breaks in the walls of the blood vessels.
• It can be difficult to detect and can be life threatening.Repair mechanisms of the body:1. Blood clotting2. Spasm of the blood vessels
Internal Bleeding:
- Invisible bleeding- Concealed bleeding• E.g ruptured spleen or liver, cerebral
hemorrhage• May become ‘revealed’ e.g. hematemesis or
melena in case of peptic ulcer bleed, hematuria from injured kidney, etc.
Causes of Internal Bleeding Due to Trauma• Blunt trauma• Penetrating trauma
Sources of internal bleeding due to trauma• intracranial hemorrhage• Hemothorax• hemopericardium and cardiac tamponade• Tears in the large blood vessels near the center of the body (aorta, superior and inferior vena cava, and their major branches).
Recognizing an Internal Bleeding
The signs of internal bleeding may be seen in either injured or suddenly ill victims:– Bright red blood from the mouth or rectum or blood in the urine– Nonmenstrual vaginal bleeding– Vomited blood; maybe bright red, dark red, or look like coffee
grounds– Black, foul smelling, tarry stools– Pain, tenderness, bruising or swelling– Broken ribs, bruises over the lower chest, or a rigid abdomen
Symptoms of Internal Bleeding• Due to trauma:– Abdominal pain and/or swelling – Light-headedness, dizziness, or fainting – Ecchymosis– Swelling, tightness, and pain – Headache and loss of consciousness
Diagnostic Exams and Tests
• Complete blood count (CBC) or hemogram• INR (international normalized ratio) and PTT
(partial thromboplastin time)• Computerized tomography (CT scan) • Ultrasound • Endoscopy, colonoscopy, and anoscopy
Operative Techniques:• Hemostats – artery forceps, clips, ligature• Electrocautery• Topical haemostatic agents: gelatin sponge
(oxygel), crushed patch of muscle, adrenaline soaked gauze
• Restoration of intravascular volume - isotonics - plasma expanders - blood and blood productsIdentify the primary cause of bleeding and treat it.
