3. CAUSES OF HAEMORRHAGE 1. Trauma 2. Infection 3. Local irritants 4.allergy 5. Surgical (intraoperative/postoperative) 6. Abnormalities in Clotting factors 7. Systemic disease 8. Viral infection 9. Scurvy

4. HAEMORRHAGE INVESTIGATIONS: Patients can be assessed by Haematological investigations The test are termed the “coagulation profile “ 1.Clotting factors 2. Bleeding time 3. Prothrombin time 4. Activated partial thromboplastin 5.Factor assay

5. CLASSIFICATION OF HAEMORRHAGE Based on source of blood loss
Based on time of occurrence
Visualisation of blood loss
Volume of blood loss
Speed of blood loss
Percentage volume of blood loss
Clinical signs of haemorrhage

6. Complications of haemorrhage Shock
Airway obstruction
Hematoma → infection, wound dehiscence Anemia Aspiration
Nerve compression

7. Hypovolumic shock: There is severe hypovolaemia, endogenous mechanism fails leads to a state called hypovolaemic shock that leads to multi organ failure .
