Lesson 1Interdisciplinary communication with ICU, ED, primary teams and nursing for urgent AKI careThis part stresses good talk between ICU, emergency, main teams, and nurses in urgent AKI care, focusing on shared understanding, clear job sharing, escalation signs, and standard handovers for better safety and results.
Essential data to share during handoffClarifying roles and responsibilitiesEscalation criteria and rapid responseCommunicating dialysis urgency and plansDocumentation and closed-loop communicationLesson 2Decision-making for renal replacement therapy in AKI: indications, timing, modality selection (intermittent hemodialysis vs CRRT vs SLED)This part covers choices for dialysis in AKI on CKD, signs to start, timing talks, and picking between regular dialysis, continuous types, or slower ones based on blood stability, tools available, and care aims.
Absolute and relative indications for RRTEarly versus delayed initiation strategiesChoosing intermittent HD versus CRRTWhen to use SLED and hybrid approachesAnticoagulation and access considerationsLesson 3Initial rapid bedside assessment: history, focused exam, volume status, hemodynamicsThis part outlines a step-by-step bedside check for AKI on CKD, mixing patient story, targeted exam, fluid check, and blood flow review to quickly spot life dangers and likely AKI cause.
Key history elements in AKI on CKDFocused exam for perfusion and congestionBedside tools for volume status assessmentBlood pressure, MAP, and perfusion targetsRisk stratification for deterioration and ICULesson 4Key laboratory interpretation: creatinine kinetics, BUN/creatinine ratio, electrolytes, acid-base analysis, lactateThis part focuses on reading main lab results in AKI on CKD, like creatinine changes, BUN to creatinine ratio, salts, acid-base balance, and lactate, to separate new from old issues and guide urgent steps.
