Haem: Neutropenic Sepsis: Free MSRA Podcast

 🎧MSRA Podcast:Neutropenic Sepsis – When Every Minute Counts! 🎧Ever heard thephrase “Time is neutrophils”? Neutropenic sepsis is one of the true medical emergencies—and a must-know for yourMSRA, acute medicine, and real-life practice. In this episode, we cut the jargon and give you a step-by-step,no-fluff breakdown of what really matters. 🗝️ Key Learning PointsDefinitionNeutropenic sepsis = sepsis in a patient with neutropenia (neutrophil count < 0.5 x 10⁹/L, or < 500/μL).Most often seen 7–14 days after chemotherapy. “Low cells + fever = act fast!”CriteriaFever ≥ 38.3°C OR other clinical features of sepsis.Neutrophil count < 0.5 x 10⁹/L (500/μL).CausesChemotherapy (biggest cause)Radiation therapyBone marrow disordersCentral lines (catheter infections)Underlying malignancy (especially haematological)Risk Factors Mnemonic:“Chemo Problems Lead to Infection Catastrophe”C: Chemo/radiationP: Prolonged neutropeniaL: Low neutrophil countI: In-dwelling lines (central venous catheter)C: Cancer (especially blood cancers)Plus: previous infections, comorbiditiesPathophysiologyNo neutrophils = no first responders.Even “normal” bugs or patient’s own gut flora can cause rapid, overwhelming infection and sepsis.Widespread infection → rapid deterioration → shock/multi-organ failure.Symptoms & SignsFever (most common, can be the only sign)Chills, rigors, sweatsTachycardia, hypotension, tachypnoeaProfound weakness, confusion, altered mental statusSometimes localising signs: line infection, cough (pneumonia), cellulitisDiagnosisFBC with differential (confirm neutropenia)Blood cultures (peripheral + line if present)Other cultures: urine, sputum as indicatedImaging: CXR, CT if needed to localise infectionAssess severity: lactate, kidney function, etc.Management (Core MSRA Emergency!)ABCs: Antibiotics Broad-spectrum—Currently!(Start IV antibiotics within 1 hour, do not wait for bloods or cultures)Hospital admission and supportive care (IV fluids, oxygen)Monitor for and treat complications: septic shock, organ dysfunctionTailor antibiotics when culture results returnConsider GCSF in select, specialist-assessed casesIf fever doesn’t settle in 48h:Broaden antibiotics (e.g. add vancomycin)If >4–6 days and no source, consider fungal infectionComplicationsSeptic shockMulti-organ failure (renal, respiratory, cardiac)Disseminated infection/abscessesHigh mortality without rapid treatmentPrognosisEarly recognition and prompt antibiotics = better outcomesDelay increases risk of death—never wait for labs if clinical suspicion is high 📝 Revision ResourcesNeutropenic Sepsis Revision Notes:https://www.passthemsra.com/topic/neutropenic-sepsis-revision-notes/Flashcards:https://www.passthemsra.com/topic/neutropenic-sepsis-flashcards/Accordion Q&A Notes:https://www.passthemsra.com/topic/neutropenic-sepsis-accordion-qa-notes/Rapid Fire Quiz:https://www.passthemsra.com/topic/neutropenic-sepsis-rapid-quiz/Online Quiz:https://www.passthemsra.com/quizzes/neutropenic-sepsis/ #MSRA#NeutropenicSepsis #Haematology #MSRARevision #PassTheMSRA #MedicalEmergency#Oncology #AcuteMedicine Exam Pearl:Fever + recent chemo = treat as neutropenic sepsisuntil proven otherwise!Start IVbroad-spectrum antibiotics immediately—secondsmatter.
