Shock — What You Do in 60 Minutes Decides If He Lives

A 25-year-old trauma patient. Pale. Restless. Tachycardic. Pressure dropping. What you do in the next 60 minutes decides whether he walks out — or doesn't. Shock is not a diagnosis. It is an emergency. And the surgeon who understands the physiology acts while others are still guessing. Most students memorize shock classifications. The great ones understand why warm shock looks nothing like cold shock — and why that difference saves lives at 3am. WHAT IS SHOCK Inadequate tissue perfusion — cellular suffocation. The lungs work. The blood has oxygen. But delivery fails. Cells die. Then organs. Then the patient. CLASSIFICATION — PUMP, PIPES, FLUID Hypovolaemic — fluid loss, haemorrhage commonest in surgical practice. Cardiogenic — pump failure, raised JVP, cold peripheries. Distributive — pipes fail, massive vasodilation. Septic shock — warm, flushed, bounding pulse. Neurogenic — bradycardia with hypotension after spinal injury. Obstructive — TCP. Tension pneumothorax, Cardiac tamponade, Pulmonary embolism. HAEMORRHAGIC SHOCK — ATLS CLASSES Class I — under 750ml, pulse normal, compensating. Class II — 750-1500ml, tachycardia, BP maintained, falsely reassuring. Class III — 1500-2000ml, BP drops, confused, needs blood not saline. Class IV — over 2000ml, immediately life threatening, massive transfusion protocol, find bleeding source and stop it surgically. Tachycardia is the first sign — always trust the pulse over the blood pressure. MONITORING Urine output — the canary in the coal mine. 0.5ml per kg per hour. Falls before BP drops. Catheterise every shocked patient. Watch that urine bag like a hawk. Cap refill, mentation, skin temperature, pulse character. MANAGEMENT ABCDE always first. Two large bore cannulas — 14 or 16 gauge at antecubital fossa. Poiseuille's law — double diameter, sixteen times the flow. Damage control resuscitation — 1:1:1 ratio PRBC, FFP, platelets. Lethal triad — hypothermia, acidosis, coagulopathy — break the cycle early. Permissive hypotension — target systolic 80-90 until surgical haemorrhage control. Stop the bleeding — no resuscitation saves a patient still actively bleeding. SEPTIC SHOCK MAP below 65 despite fluids — vasopressors needed. One hour bundle — cultures before antibiotics, broad spectrum antibiotics, 30ml per kg crystalloid, measure lactate, start noradrenaline if needed. Lactate above 4 with hypotension — septic shock. Serial lactate shows if resuscitation is working. Surgery must be understood — not memorized. 🎙️ Free on Spotify: https://open.spotify.com/show/4IcchE2...
