Editor's Notes

  1. SIRS criteria are very non-specific,[9] and must be interpreted carefully within the clinical context. These criteria exist primarily for the purpose of more objectively classifying critically ill patients so that future clinical studies may be more rigorous and more easily reproducible. The causes of SIRS are broadly classified as infectious or noninfectious. As above, when SIRS is due to an infection, it is considered sepsis. Noninfectious causes of SIRS include trauma, burns, pancreatitis, ischemia, and hemorrhage.[
  2. quickly determine the degree of illness of a patient It is based on data derived from four physiological readings (systolic blood pressure, heart rate, respiratory rate, body temperature) and one observation (level of consciousness, AVPU). ;

  4. CURB-65, also known as the CURB criteria, is a clinical prediction rule that has been validated for predicting mortality in community-acquired pneumonia[1] and infection of any site.[2] The CURB-65 is based on the earlier CURB score[3] and is recommended by the British Thoracic Society for the assessment of severity of pneumonia.[4]
  5. Who need CT
  6. If not- age, anticoagulant, mechanism of injury, LOC
  7. After TIA to predict the chance of stroke
  8. Score &amp;gt;= 6 have 8.1% chance of getting stroke within 2 days / 35.5% in the next week Score &amp;gt;4 should be assessed within 24hours by specialist
  9. Decision for thromboprophylaxis Based on stroke risk
  10. Decision for thromboprophylaxis Based on stroke risk
  11. Useful in Assessing the bleeding risk Has predictive value for cardiovascular events + mortality in anticoagulated AF patients
  12. If HAS-BLED score &amp;gt; 3, the risk of major bleed exceed the risk of thrombotic event

CURB-65, also known as the CURB criteria, is a clinical prediction rule that has been validated for predicting mortality in community-acquired pneumonia[1] and infection of any site.[2] The CURB-65 is based on the earlier CURB score[3] and is recommended by the British Thoracic Society for the assessment of severity of pneumonia.[4]
  14. The risk of death at 30 days increases as the score increases:
  15. Ranson’s criteria – c2h5oh-induced pancreatitis and can only be fully applied after 48h
  16. Ranson’s criteria – c2h5oh-induced pancreatitis and can only be fully applied after 48h Severe- ICU/HDU

  18. Untreated severe ulcerative colitis shows a mortality of 24% This was reduced to &amp;% with the introduction of IC steroids
  19. 3 symp 3 signs 2 lab Problem- shifts of WBC in not routinely available
  20. False negative high in women Sesnitivity only 67% Sensitivity in men 93%
