Definition of
SEPSIS SEVERE SEPSIS SEPTIC SHOCK |
Sepsis - SIRS with likely infective cause
Severe Sepsis - Sepsis with organ failure/dysfunction eg oliguria, lactic acidsosis, mental status change Septic shock- Hypotension that does not respond to fluid replacement |
|
|
DEFINITION OF SIRS
|
Systemic inflammtory response manifested by 2 or more of:
RR >20 or CO2 <32 HR >90 Temp >38 or <36 WCC >12 or <4 (or >10% immature band forms) |
|
|
Sepsis investigations
|
septic screen: blood cultures x2, urtine culture, suptum/tracheal asp culture, wound swab
bloods: FBC eLFTs Coags ABG glucose CXR & AXR ?CT (esp if brain/abdo source suspected) ?LP ?nasopharyngeal swab for viruses eg H1N1, SARS ?MRI if severe back pain |

LOW YIELD INTEREST
Respiratory complications of infectious mononucleosis are uncommon. - what are some |
-upper airway obstruction from tonsillar enlargement or a pharyngeal abscess,
-bilateral hilar adenopathy, -exudative pleural effusions, - interstitial pneumonitis, - superimposed bacterial pneumonia - septic thrombophlebitis +/-emboli. A patient can develop bilateral anaerobic empyema as complication of infectious mononucleosis through two potential mechanisms, both requiring the initial development of a pharyngeal abscess. Patients can develop septic thrombophlebitis of the jugular veins resulting in septic emboli (LeMierre’s syndrome) or the abscess can invade the space between the alar and the prevertebral fasciae of the neck into a space known as “the danger space”. Once an infection enters this danger space, it has direct access into the mediastinum, resulting in mediastinitis.6 Only 2 cases of EBV-related descending necrotizing mediastinitis have been reported in the literature |
