2025 Multiprofessional Critical Care Review: Adult Online-Shock

Video Transcription

Video Summary

This talk reviews shock syndromes, focusing on the four Schubin-Weil shock types: distributive, cardiogenic, hypovolemic, and obstructive shock. Shock is defined as inadequate tissue oxygen delivery, with lactate and capillary refill as imperfect biomarkers. Treatment prioritizes airway protection, cautious intubation, and circulation optimization, mainly via fluids and vasopressors like norepinephrine. Dopamine is generally avoided, especially in cardiogenic shock, due to higher mortality and arrhythmias. Vasopressin is used adjunctively at higher norepinephrine doses, and steroids may help reduce vasopressor duration despite side effects. Fludrocortisone shows some benefit but lacks consensus. Distributive shock, mainly from sepsis, is most common; management includes source control and supportive care. Cardiogenic shock requires urgent reperfusion and potential mechanical devices. Obstructive shock—due to causes like PE, tamponade, or pneumothorax—benefits from ultrasound diagnosis for rapid treatment. Overall, identifying shock type guides therapy, with many patients experiencing mixed shock forms.
