Decompensated Heart Failure Management Strategies Wet (volume overloaded) vs Dry (euvolemic) and Cold (low cardiac output) vs Warm (normal cardiac output) - Dr. Eric Strong @DrEricStrong - Strong Medicine https://www.youtube.com/c/EricsMedicalLectures/ #Decompensated #HeartFailure #management #CHF #cardiology

Hyperkalemia - Management Algorithm • IV calcium • IV insulin and glucose and/or salbutamolt • Consider bicarbonate if acidosis without volume overloads • Consider IV furosemide unless anuric ESKD or severe volume depletion • Consider K+ binder • Consider Dialysis Serum potassium and ECG changes • 5.5-6.5 mmol/l - Tall, "peaked" T waves with narrow base, best seen in precordial leads • 6.6-8.0 mmol/l - Peaked T waves, Prolonged PR interval, Decrease amplitude of P waves, Widening of QRS complex • >8.0 mmol/l - Absence of T wave, Intraventricular blocks, fascicular blocks. bundle branch blocks, QRS axis shift, Progressive widening of QRS resulting in bizarre morphology, "Sine wave" pattems (sinoventricular rhythm), VF, asystole #hyperkalemia #potassium #high #diagnosis #management #algorithm #treatment

Guide to Acute Kidney Injury (AKI) What to ask/look for: - HPI, PMH, full ROS - Nephrotoxins (NSAlDs, contrast, OTCs, herbals, abx, illicits, chemo, immunosuppression) - Hx of AKI/CKD - Recent hypo/hypertension? - TTE/liver fxn? - BMP, cap, CBC w/ diff - Urinalysis/microscopy/UOP/weights - Urine Na/K/Cl/urea/protein/Cr - Renal/bladder US w/ PVR - CPK, uric acid (rhabdo/TLS) Causes of Inpatient AKI (Liano 1996) - ATN - 45% - Pre-renal disease — 21% - AKI on CKD— 13% (mostly ATN and pre-renal) - Urinary tract obstruction — 10% (most often prostate related) - Glomerulonephritis or vasculitis — 4% - Atheroemboli — 1% #AcuteKidneyInjury #AKI #Nephrology #Diagnosis #Algorithm #Causes #Differential

Intern Pocket Cards - Inpatient Bowel Regimen Guide Osmotic agents (draws water into bowel, thereby loosening stool and promoting evacuation): • Polyethylene glycol - Nausea, bloating, cramping • Lactulose, Sorbitol - Abdominal bloating, flatulence • Glycerin - Rectal irritation • Magnesium sulfate PO, Magnesium citrate - Watery stools and urgency Stimulant laxatives: • Bisacodyl - Rectal irritation • Senna - Melanosis coli Bulk-forming laxatives (fiber absorbs excess water and stimulates elimination): • Psyllium - Impaction above strictures, fluid overload, gas, and bloating Rectal distension: • Tap water enema - Discomfort during procedure Notice that docusate is not on here as it is a #TWDFNR Dr. Satya Patel @SatyaPatelMD Full Inpatient Pocket Cards Collection: https://bit.ly/pocketcardset #Bowel #Regimen #Guide #Inpatient #medications #constipation #pharmacology #table #agents #internship #comparison

Effect of PEEP on Lung Recruitment - Bag-Mask Ventilation - Cadaver Simulation Simulation shows before and after adding 5cm H2O of PEEP. You can see the effect PEEP has on the lungs to maintain recruitment and ultimately prevent ventilation induced lung injury.

Refeeding Syndrome: Pathogenesis and clinical findings Patients at Risk of Refeeding Syndrome: - Little or no nutritional intake in recent past - Significant weight loss - Low BMI < 18.5 kg/m2 - Electrolyte disturbances: low K, PO4& Mg prior to feeding - History of alcohol abuse or drugs including diuretics, insulin, chemotherapy and or antacids RAPID REFEEDING -> -> Incr glucose, fluid, salt and nutrients from any source; oral, enteral or parenteral -> Insulin secretion • Incr Na retention -> Fluid overload -> - CHF - Pulmonary Edema - Cardiac Arrhythmias / Death • Incr Glucose Metabolism -> Decr Thiamine - Wernicke-Korsakoff Syndrome - Metabolic Acidosis • Shift of K, PO4 and Mg into cells -> Decr Serum K, Mg, Ca -> Changes in action potential threshold - Tetany - Cardiac Arrhythmias / Death • Incr synthesis of proteins -> decr Serum PO4 -> decr RBC ATP + 2,3-DPG -> - hemolysis - anemia - CNS: Tremors, Ataxia, Coma, Delirium - GI: Anorexia, Constipation - MSK: Weakness #Refeeding #Syndrome #diagnosis #pathophysiology #symptoms #signs
