Sudden death is unexpected death within 1h, cardiac/arrhythmic. Urgent evaluation/prevention are used.
急诊科Shock is inadequate tissue perfusion, distributive/hypovolemic/cardiogenic. Fluids/inotropes are used.
急诊科Septic shock is shock from sepsis, with hypotension despite fluids. Antibiotics/ICU are used.
急诊科Hemorrhagic shock is shock from blood loss. Transfusion/surgery are used.
急诊科Neonatal shock is circulatory failure in the newborn from sepsis, hypovolemia, or cardiac causes, presenting with pallor and weak pulses. Immediate resuscitation is needed.
急诊科This is the commonest type of ectopic pregnancy: the ovum is fertilized in the ampulla but the zygote is blocked and implants/develops in the tube. Ampullary commonest (50%-70%), isthmic next (30%-40%), fimbrial/interstitial rarest (1%-2). Commonest cause
急诊科Berylliosis is chronic granulomatous lung disease from beryllium exposure; avoid exposure, steroids in symptomatic, treat like sarcoid.
急诊科Electrolyte imbalance is disturbance in serum sodium/potassium/calcium/magnesium/phosphate: arrhythmia, weakness, confusion; common in renal disease/diuretics/illness; treat by correcting underlying cause and repletion.
急诊科Hypokalemia is serum potassium <3.5 mmol/L: muscle weakness, cramps, arrhythmia/U waves; causes diuretics, GI loss, hyperaldosteronism; treat by oral/IV potassium repletion.
急诊科Hyperkalemia is serum potassium >5.5 mmol/L: weakness, arrhythmia/peaked T waves; causes renal failure, ACEi/ARB, spironolactone, rhabdomyolysis; urgent treatment: calcium, insulin/glucose, kayexalate, dialysis.
急诊科Metabolic alkalosis is primary bicarbonate excess: vomiting/NG loss, diuretics, hypokalemia; weakness, hypoventilation; treat by chloride/potassium repletion and stopping diuretics.
急诊科Lactic acidosis is elevated lactate (>5 mmol/L) from tissue hypoperfusion/hypoxia (type A) or impaired metabolism (type B: sepsis, metformin, liver failure, malignancy); treat underlying cause, perfusion.
急诊科Hypernatremia is serum sodium >145 mmol/L from water deficit: thirst, confusion, seizures; from diabetes insipidus/insufficient intake; correct slowly with hypotonic fluids.
急诊科Dehydration is excessive body-water loss: thirst, dry mucous membranes, decreased urine output, tachycardia, hypotension; from insufficient intake/GI losses; treat by oral/IV rehydration.
急诊科Bacteremia occurs when external bacteria enter the bloodstream via skin/mucosal portals, multiply, and disseminate—often severe. Catheters/surgical stomas commonly cause it, leading to acute metastatic multiorgan infection. Blood cultures must be taken im
急诊科TSS is a syndrome of fever, rash, syncope, hypotension/shock, and multiorgan involvement, usually caused by one or more S. aureus toxins.
急诊科Septic shock (formerly infectious shock) is shock from sepsis defined by inadequate tissue perfusion: persistent hypotension after volume challenge or blood lactate ≥4 mmol/L. Usually due to Gram-negative bacilli, seen in acute suppurative obstructive cho
急诊科Vibrio parahaemolyticus food poisoning is an acute or subacute illness caused by eating food contaminated with or containing this bacterium. V. parahaemolyticus is a common food poisoning pathogen accounting for a substantial proportion of bacterial food
