Vital Emergencies
What are Vital Emergencies?
Vital emergencies are clinical situations that endanger the patient's life in the short term (minutes to hours). They require immediate management, often in the pre-hospital setting (EMS, mobile ICU) and then in the emergency department and/or intensive care unit. The prognosis depends on the speed and quality of management.
The main vital emergencies are:
- Acute respiratory distress (ARD): ARDS, hypoxemic pneumonia, pulmonary embolism, acute pulmonary edema (APE), severe acute asthma, COPD exacerbation.
- Cardiac arrest (CA): cardio-respiratory arrest of medical (infarction, myocarditis) or traumatic origin.
- Shock states: septic shock, hypovolemic shock (hemorrhage), cardiogenic shock, obstructive shock (pulmonary embolism, tamponade, tension pneumothorax), anaphylactic shock.
- Coma: metabolic coma (hypoglycemia, ketoacidosis), toxic coma (drug poisoning), neurological coma (stroke, meningitis, traumatic brain injury), post-anoxic coma.
- Severe traumatic emergencies: polytrauma, severe traumatic brain injury (GCS ≤ 8), massive hemorrhage, extensive burns.
- Severe cardiovascular emergencies: myocardial infarction with cardiogenic shock, aortic dissection, fulminant myocarditis.
- Severe neurological emergencies: massive ischemic or hemorrhagic stroke, bacterial meningitis, generalized epilepsy (status epilepticus), subarachnoid hemorrhage.
- Severe metabolic emergencies: diabetic ketoacidosis, hyperosmolar coma, severe hypoglycemia, acute adrenal insufficiency.
- Severe poisonings: barbiturates, benzodiazepines, opioids, cyanide, paraquat, methanol, household products.
- Severe obstetrical emergencies: postpartum hemorrhage, eclampsia, amniotic fluid embolism, uterine rupture.
- Severe infectious emergencies: severe sepsis, septic shock, purulent meningitis, toxic shock.
How to Recognize a Vital Emergency? (Warning Signs)
Warning signs of a vital emergency are:
- Unconsciousness: patient not responding to verbal or painful stimulation (Glasgow Coma Scale ≤ 8).
- Absence of breathing (apnea) or agonal breathing (gasps).
- Cyanosis: bluish discoloration of lips, fingers, or mucous membranes.
- Respiratory distress: severe dyspnea (inability to speak, tachypnea > 30/min, SpO2 < 90%).
- Absence of pulse (cardiac arrest).
- Severe arterial hypotension: SBP < 80-90 mmHg, MAP < 65 mmHg.
- Generalized seizures lasting more than 5 minutes (status epilepticus).
- Extreme pallor, mottling, cold extremities (shock).
- Massive external hemorrhage (hemoptysis, hematemesis, melena, wound).
- Severe trauma: polytrauma, fall from height, high-energy road traffic accident.
In the presence of these signs, call emergency services immediately (197 in Tunisia).
How is the Management of Vital Emergencies in Tunisia?
Management is structured according to the international ABCDEF protocol (derived from ATLS) and relies on a 24/7, 7 days a week organization.
Pre-hospital Phase (EMS, Emergency Medical Dispatch, number 197)
- Medical dispatch (EMS): an emergency physician assesses the situation by phone, gives initial advice (recovery position, bystander CPR, tourniquet) and dispatches a mobile ICU team (ambulance).
- ABCDEF protocol at the scene:
- A (Airway): airway control, suction, oropharyngeal airway, intubation if GCS ≤ 8 or severe respiratory distress.
- B (Breathing): oxygen therapy (SpO2 ≥ 90-95%), bag-valve-mask ventilation, decompression of tension pneumothorax.
- C (Circulation): vascular access, fluid resuscitation (crystalloids), control of external hemorrhage (compression, tourniquet), norepinephrine if refractory shock, chest compressions if cardiac arrest, early defibrillation (AED).
- D (Disability): neurological assessment (Glasgow Coma Scale, pupil size).
- E (Exposure): complete undressing, search for hidden injuries, prevention of hypothermia.
- F (Fast): FAST ultrasound (if available) to search for hemoperitoneum, hemopericardium, hemothorax.
- Medically supervised transport to the appropriate facility (level I or II emergency department, intensive care unit, operating room).
Hospital Phase (Emergency Department, Resuscitation Bay)
Immediate reception and management (Code Red):
- Multidisciplinary team mobilized: emergency physician, intensivist, anesthesiologist, surgeon, radiologist, radiology technician, nurses.
- Continuous monitoring: cardiac monitor, oximetry, non-invasive blood pressure (then invasive).
- Rapid laboratory tests: CBC, platelets, coagulation, electrolytes, blood glucose, creatinine, troponin, lactate, blood gas, blood alcohol, toxicology screen (as indicated).
- Emergency imaging studies: FAST ultrasound, chest X-ray, Whole Body CT for severe trauma.
- Continuation of ABCDEF resuscitation: intubation, mechanical ventilation, fluid resuscitation, vasopressors (norepinephrine), inotropes (dobutamine), massive transfusion (1:1:1 ratio), sedation.
- Specific etiological treatment (see below).
Specific Management of the Main Vital Emergencies
Severe Acute Respiratory Distress:
- High-flow nasal oxygen (Optiflow), NIV (mask), intubation and invasive mechanical ventilation if failure.
- Etiological treatment: antibiotics (pneumonia), corticosteroids (asthma, COPD, ARDS), diuretics (cardiogenic pulmonary edema), anticoagulants (pulmonary embolism).
Cardiac Arrest:
- High-quality CPR (compressions 100-120/min, 5-6 cm depth), early defibrillation (VF/VT).
- Epinephrine (1 mg IV/3-5 min), amiodarone (refractory VF/VT).
- Intubation, mechanical ventilation.
- Search for reversible causes (4Hs and 4Ts).
- Post-cardiac arrest care: therapeutic hypothermia (32-36°C, 24h), emergency coronary angiography.
Shock States:
- Fluid resuscitation (crystalloids 30 mL/kg), norepinephrine (target MAP ≥ 65 mmHg).
- Septic shock: antibiotics < 1h, source control, corticosteroids (hydrocortisone 200 mg/day) if refractory.
- Cardiogenic shock: dobutamine, coronary revascularization (PCI < 2h), circulatory support (VA ECMO).
- Hypovolemic shock: massive transfusion (1:1:1 ratio), tranexamic acid, hemorrhage control (surgery, embolization).
- Obstructive shock: thrombolysis/embolectomy (PE), pericardiocentesis (tamponade), decompression (tension pneumothorax).
Coma:
- Airway protection (intubation if GCS ≤ 8).
- Correction of metabolic causes: 30% glucose if hypoglycemia, naloxone (Narcan®) if suspected opioid overdose, flumazenil (Anexate®) if benzodiazepines (caution).
- Etiological workup: brain CT, LP if meningitis, EEG, toxicology screen.
Severe Traumatic Emergencies:
- Damage control resuscitation (massive transfusion, tranexamic acid).
- Damage control surgery (laparotomy, thoracotomy, external fixation).
- Neurosurgery (hematoma evacuation, ICP monitoring).
- Radiological embolization (pelvis, liver, spleen).
Admission to Intensive Care (Critical Care)
After initial management (or immediately if the patient does not require surgery), the patient is transferred to the multidisciplinary or specialized intensive care unit:
- Continuous hemodynamic monitoring: NIBP or invasive arterial pressure, monitor, oximetry, CVP, sometimes cardiac output (PiCCO, Swan-Ganz).
- Lung-protective mechanical ventilation: low tidal volume (6-8 mL/kg), adapted PEEP, prone positioning if ARDS.
- Treatment of organ failure: continuous hemofiltration (CVVHDF) for acute kidney injury, vasopressors/inotropes for shock, corticosteroids, transfusion.
- Early enteral nutrition: nasogastric tube, target 20-25 kcal/kg/day.
- Complication prevention: pressure ulcers (alternating pressure mattress), DVT (LMWH), nosocomial infections (strict care, antibiotic de-escalation), adapted sedation-analgesia.
What are the Risks and Complications of Vital Emergencies?
Vital emergencies expose patients to serious complications even with optimal management:
- Death: variable mortality depending on the emergency (cardiac arrest 8-25%, septic shock 30-50%, severe ARDS 40-60%, polytrauma 10-20%).
- Severe neurological sequelae (persistent vegetative state, hemiplegia, tetraplegia, cognitive disorders) after cardiac arrest, severe traumatic brain injury, massive stroke, post-anoxic encephalopathy.
- Multiple organ dysfunction syndrome (MODS): ARDS, acute kidney injury (AKI), liver failure, DIC.
- Nosocomial infections: VAP (ventilator-associated pneumonia), catheter-related bacteremia, urinary tract infection, secondary sepsis.
- Intensive Care Unit-Acquired Weakness (ICUAW): neuropathy and myopathy (30-50% of stays > 7 days).
- Post-traumatic stress disorder (PTSD): up to 30-50% of vital emergency survivors.
What to Do After a Vital Emergency? Post-Intensive Care Rehabilitation
Discharge from intensive care (duration from a few days to several months) marks the beginning of multidisciplinary rehabilitation:
- Physical and respiratory therapy: restoration of muscle strength, gait retraining, bronchial clearance.
- Speech therapy / neuropsychology: cognitive rehabilitation (memory, attention, executive functions), swallowing rehabilitation (risk of aspiration).
- Occupational therapy: relearning activities of daily living, home adaptation.
- Psychologist / Psychiatrist: management of post-traumatic stress disorder (PTSD), anxiety, depression.
- Specialized follow-up: cardiology (post-cardiac arrest, post-PCI), neurology (post-TBI, post-stroke), nephrology (post-AKI), pulmonology (post-ARDS).
- Social worker: assistance with returning to work, disability recognition, financial aid.
