Sepsis Flashcards
What is sepsis?
Life threatening organ dysfunction caused by a dysregulated host response to infection
What is septic shock?
A more severe form of sepsis which occurs when the BP drops despite fluid resus. It is diagnosed with:
- A low MABP below 65mmHg: may require escilation for vasopressors
- Raised serum lactate above 2mmol/L
What is the qSOFA score?
Respiratory rate > 22/min
Altered mentation
Systolic blood pressure < 100mmhg
What are the risk factors for sepsis
- Extreme ages,
- Chronic conditions,
- Chemotherapy/immunosuppressants or steroids
- Surgery, recent trauma or burns,
- Pregnancy and childbirth
- Indwelling medical devices
What is the presentation of sepsis?
- High HR, low BP, high RR, low O2 sats
- Signs of potential source eg, cellulitis, discharge
- Reduced urine output
- Mottled skin,
- Cyanosis,
- Arrhythmias such as new onset AF,
- Non blanching rash seen in meningococcal septicaemia
What are the investigations for sepsis?
- Sepsis 6,
- Bloods: FBC, U&Es, LFTs, CRP, glucose, clotting, blood cultures,
- ABG
Explain the sepsis 6
- Take blood cultures
- Start broad spectrum antibiotics
- Measure serum lactate
- Measure Urine output
- Give oxygen
- Give IV fluids
What is neutropenic sepsis?
Sepsis in someone with a neutrophil count below 1. Anyone on chemotherapy with a temp > 38 is neutropaenic sepsis until proven otherwise
Name some medications which can cause neutropenia
- Chemotherapy,
- Clozapine,
- Hydroxychloroquine
- Methotrexate,
- Sulfasalazine,
- Carbimazole,
- Quinine
- Infliximab,
- Rituximab
What is the management of neutropenic sepsis?
Immediate broad spectrum abx such as tazocin
