Shock States
Are you or a loved one experiencing acute circulatory failure, severe hypotension, signs of poor organ perfusion? Management of shock states in Tunisia is provided by experienced intensivists and cardiologists, with modern techniques (vasopressors, inotropes, ECMO) and competitive prices starting from €1500.
What are shock states?
Shock is an acute circulatory failure leading to tissue hypoperfusion and organ dysfunction that is life-threatening. It manifests as arterial hypotension (systolic blood pressure < 90 mmHg or mean arterial pressure < 65 mmHg) and signs of poor peripheral perfusion (mottling, cold extremities, oliguria, confusion).
The four types of shock states
- Hypovolemic shock: decrease in circulating blood volume (hemorrhage, severe dehydration, extensive burns, acute pancreatitis).
- Cardiogenic shock: heart pump failure (extensive myocardial infarction, myocarditis, cardiomyopathy, end-stage heart failure, arrhythmia).
- Septic shock: vasoplegia and relative hypovolemia secondary to severe infection (severe sepsis, bacteremia, endotoxins).
- Obstructive shock: mechanical obstruction to filling or ejection of the heart (massive pulmonary embolism, cardiac tamponade, tension pneumothorax, tight aortic stenosis).
Clinical signs of a shock state
Septic shock manifests with several clinical and biological signs. Arterial hypotension is present, with systolic blood pressure below 90 mmHg or mean arterial pressure below 65 mmHg. Tachycardia appears, with a rapid pulse above 100 beats per minute, or sometimes bradycardia in terminal shock. Tachypnea, i.e., rapid breathing above 20 per minute, is observed. Oliguria, with urine output below 0.5 mL/kg/h, or anuria may occur. Skin mottling, cold extremities and cyanosis are common. Altered consciousness manifests as confusion, agitation, drowsiness or coma. Finally, elevated lactate, above 2 mmol/L, indicates tissue hypoperfusion.
Comparative table of different types of shock
| Parameter | Hypovolemic shock | Cardiogenic shock | Septic shock | Obstructive shock |
|---|---|---|---|---|
| Central venous pressure (CVP) | Low | Elevated | Low or normal | Elevated |
| Pulmonary artery pressure (PAP) | Low | Elevated | Low or normal | Elevated (PE), normal (tamponade) |
| Cardiac output (CO) | Decreased | Severely decreased | Decreased (then normal or elevated if vasoplegia) | Decreased |
| Systemic vascular resistance (SVR) | Elevated | Elevated | Low (vasoplegia) | Elevated (except anaphylactic shock) |
| Main treatment | Fluid resuscitation, transfusion, vasopressors if resistant | Inotropes (dobutamine), coronary revascularization (PCI), circulatory support (ECMO, VAD) | Antibiotics, fluid resuscitation, norepinephrine, source control | Etiological treatment (thrombolysis/embolectomy, pericardial drainage, exsufflation) |
Initial management common to all shocks (ABC + fluid resuscitation)
Initial management of septic shock is based on the ABC protocol. Airway patency is verified, oxygen therapy is administered, and a large-bore venous access is placed. Continuous monitoring is provided by cardiac monitor, pulse oximetry and blood pressure. Urgent workup includes CBC, platelets, coagulation, electrolytes, creatinine, blood gases, lactate, troponin, ECG and clinical ultrasound. Fluid resuscitation is first-line, with 500 to 1000 mL of crystalloids infused over 15 to 30 minutes. The goal is to achieve a MAP ≥ 65 mmHg, urine output > 0.5 mL/kg/h and improvement of mottling. Vasopressors are started if hypotension persists despite 2 to 3 liters of crystalloids. Norepinephrine is the first-line vasopressor, with initial doses of 0.05 to 0.1 µg/kg/min, titrated up to 0.5 to 1 µg/kg/min.
Specific management according to shock type
1. Hypovolemic shock (hemorrhagic or dehydration)
Treatment of hemorrhagic shock is based on several pillars. Hemorrhage control is ensured by direct compression, tourniquet, hemostatic dressing, surgical ligation or radiological embolization. Aggressive fluid resuscitation is performed with crystalloids, then packed red blood cells if hemoglobin is below 7-8 g/dL. Massive transfusion protocol is initiated in case of massive hemorrhage, with a 1:1:1 ratio of packed red blood cells, platelets and plasma. Vasopressors, such as norepinephrine, are used only if shock persists after fluid resuscitation and transfusion. Finally, hydroelectrolyte disorders are corrected.
2. Cardiogenic shock
Treatment of cardiogenic shock is based on several strategies. Emergency coronary revascularization is performed by primary angioplasty for ST-segment elevation myocardial infarction, or by coronary artery bypass if anatomically suitable. Inotropes like dobutamine are first-line to increase cardiac contractility. If hypotension persists despite dobutamine, norepinephrine is added. Mechanical circulatory support is used for refractory shocks, including venoarterial ECMO, intra-aortic balloon pump, or ventricular assist device. Daily echocardiography evaluates ventricular function.
3. Septic shock
Management of septic shock is based on several urgent measures. Broad-spectrum empirical antibiotic therapy is administered within the hour. Fluid resuscitation of 30 mL/kg of crystalloids is performed within the first 3 hours. Norepinephrine is used to maintain mean arterial pressure ≥ 65 mmHg. Corticosteroids are added if shock is refractory to norepinephrine. Source control is essential, through drainage or surgery. Hemofiltration is initiated in case of acute kidney injury.
4. Obstructive shock
Obstructive shock requires specific treatment according to the cause. Massive pulmonary embolism is treated with intravenous heparin, thrombolysis with tenecteplase in case of shock, or embolectomy. Cardiac tamponade is managed by immediate echo-guided pericardial drainage. Tension pneumothorax is decompressed by needle exsufflation then chest tube drainage. Severe aortic stenosis is treated by percutaneous or surgical valve replacement.
Advanced hemodynamic monitoring
Advanced hemodynamic monitoring relies on several devices. An arterial catheter allows continuous mean arterial pressure measurement and blood sampling. A central venous catheter measures central venous pressure and administers vasopressors. A pulmonary artery catheter, or Swan-Ganz, is used in complex shocks. Non-invasive monitors like PiCCO or Doppler ultrasound estimate cardiac output.
Supportive care in intensive care
ICU management includes several supportive measures. Mechanical ventilation is provided with lung protection. Continuous hemofiltration performs renal replacement therapy. Early enteral nutrition is initiated via nasogastric tube. Prevention of complications such as pressure ulcers, thrombosis or infections is essential. Adapted sedation-analgesia is administered in case of intubation.
Risks and complications of shock states
Shock can lead to several severe complications. Multiple organ failure manifests as ARDS, renal or liver failure. Disseminated intravascular coagulation may occur. Extremity ischemia is possible under high doses of vasopressors. Myocardial infarction or extension may complicate cardiogenic shock. Acquired weakness in ICU affects 30 to 50% of patients. Post-intensive care syndrome associates cognitive disorders and post-traumatic stress. Mortality varies according to shock type.
Post-ICU rehabilitation
Post-shock rehabilitation is multidisciplinary. Intensive motor physiotherapy restores muscle strength, walking and balance. Speech therapy or neuropsychology provides cognitive rehabilitation. A psychologist or psychiatrist manages post-traumatic stress and anxiety. Cardiology follow-up is provided after cardiogenic shock. Nephrology follow-up is initiated after septic or hypovolemic shock. Control consultations are scheduled at 1, 3, 6 and 12 months.

Frequently asked questions about shock states
1What is the difference between shock and simple hypotension?
Hypotension is a drop in blood pressure, but it does not necessarily imply tissue hypoperfusion. Shock combines hypotension (MAP < 65 mmHg) with signs of poor organ perfusion: mottling, cold extremities, oliguria, confusion, elevated lactate. A patient can be hypotensive without being in shock (e.g., elderly patient on antihypertensives), and conversely, a patient can be in shock with normal blood pressure if compensatory mechanisms are effective (e.g., early septic shock with vasoconstriction).
2How do doctors distinguish between the four types of shock on admission?
Distinction is based on history (trauma, chest pain, fever, dyspnea), clinical examination (jugular venous distension, lung auscultation, mottling, temperature), additional tests: ECG, cardiac ultrasound (FAST, lung ultrasound), blood gases (lactate, pH, base excess), chest X-ray, and sometimes right heart catheterization (Swan-Ganz) or advanced hemodynamic monitoring (PiCCO).
3Is fluid resuscitation always beneficial in shock states?
Fluid resuscitation is beneficial in hypovolemic and septic shock, where blood volume is decreased. In cardiogenic shock, it is necessary to limit fluids to avoid pulmonary overload (pulmonary edema). In obstructive shock, fluid resuscitation is contraindicated (tamponade, pulmonary embolism) until the obstruction is relieved, as it would worsen right heart failure.
4What are the side effects of vasopressors (norepinephrine)?
Norepinephrine can cause extremity ischemia (fingers, toes) due to excessive vasoconstriction, cardiac rhythm disorders (tachycardia, arrhythmias), increased myocardial oxygen consumption, hyperglycemia, lactic acidosis (at very high doses). Close monitoring of extremities, ECG, and blood glucose is necessary.
5What is the difference between an inotrope and a vasopressor?
Inotropes (dobutamine, milrinone, levosimendan) increase cardiac contractility and cardiac output, but they have a vasodilatory effect (they lower blood pressure). Vasopressors (norepinephrine, vasopressin) increase systemic vascular resistance and blood pressure, but they do not increase (or only slightly) cardiac output. In cardiogenic shock, both are combined: dobutamine for contractility and norepinephrine for pressure.
6What are the criteria for brain death or withdrawal of active therapies?
Brain death diagnosis is based on clinical criteria (unresponsive coma, absence of brainstem reflexes, apnea) and paraclinical criteria (flat electroencephalogram, absence of cerebral blood flow on Doppler or angiography). Withdrawal of active therapies is a collegial decision by the medical team, in case of refractory multiple organ failure, after discussion with relatives, and in compliance with the patient's advance directives.
7Is ECMO indicated for all cardiogenic shocks?
Venoarterial ECMO (extracorporeal membrane oxygenation) is reserved for refractory cardiogenic shocks, i.e., those that do not respond to inotropes and norepinephrine, or while awaiting revascularization, heart transplantation or a VAD (ventricular assist device). It is indicated in case of severe shock with organ failure, or out-of-hospital cardiac arrest with return of spontaneous circulation (refractory cardiac arrest). It is contraindicated in case of irreversible neurological disease, advanced multiple organ failure, or advanced age (> 70-75 years depending on centers).
