Management of Critical Conditions

For medical students2 min readUpdated 2026-10-10

Critical conditions represent life-threatening situations where adaptive mechanisms are depleted. Management requires immediate intervention and a clear understanding of emergency care algorithms. All therapeutic measures are strictly based on four fundamental principles: etiologic, pathogenetic, sanogenetic, and symptomatic. Only simultaneous intervention targeting the cause, mechanisms of development, defensive forces, and distressing manifestations can save the patient's life.

Etiologic PrincipleAims to completely eliminate or reduce the impact of the primary cause of the critical condition.
Pathogenetic PrincipleEnsures the blockade of key links in pathogenesis and the breaking of vicious cycles of the disease.
Sanogenetic PrincipleInvolves the robust activation of adaptive mechanisms: defense, compensation, and restoration.
Specific TherapyIn critical conditions caused by poisoning, the administration of antidotes is mandatory.

Etiologic Therapy: Eliminating the Root Cause

Every critical condition is triggered by a specific event. The primary goal of etiologic treatment is the complete cessation or, if impossible, the maximal reduction of the intensity and scale of the factors that caused the emergency.

Therapy must target two groups of factors:

Without reliably eliminating the underlying cause, all other therapeutic measures will remain merely temporary.

Pathogenetic Treatment: Breaking Vicious Cycles

While etiologic therapy addresses the cause, pathogenetic treatment targets the mechanisms of disease development. Its main goal is to block key links in the pathogenesis of the critical condition. The choice of specific methods always depends on the type of emergency.

A critical task at this stage is to break the vicious cycles of the disease—situations where the consequence of a pathological process itself becomes the cause of its further progression.

Key goals of pathogenetic therapy include:

Sanogenetic Therapy: Mobilizing Reserves

The human body possesses powerful survival resources. The goal of sanogenetic therapy is to activate and potentiate the patient's own adaptive mechanisms. These include defense, compensation, adaptation, and restoration reactions of damaged structures and functions.

Effective sanogenetic support is achieved by:

Symptomatic Treatment: Relieving Distressing Manifestations

The essence of symptomatic treatment in critical conditions is the elimination of distressing symptoms and sensations. At first glance, they may seem secondary, but in reality, they severely exacerbate the patient's condition and exhaust the nervous system.

Primary targets of symptomatic therapy:

Mnemonic

To quickly memorize the four principles of critical condition management, use the rule "EPSS": Etiologic (remove the cause), Pathogenetic (break vicious cycles), Sanogenetic (stimulate defense), Symptomatic (relieve suffering).

Frequently asked questions

What are some examples of vicious cycles in shock or other critical conditions?

Critical conditions involve various vicious cycles (Circulus vitiosus) that potentiate disorders. Key examples include:

  • Impaired blood flow — pooling of blood in vessels decreases venous return and cardiac output, leading to an even greater drop in circulating blood volume.
  • Heat stroke — elevated temperature increases neuromuscular excitability, causes seizures, and enhances thermogenesis, driving temperature up further.
  • Sepsis — toxin concentration impairs liver detoxification, causing progressive intoxication.
  • Shock — metabolic acidosis and vasoactive metabolites exacerbate microvessel paresis, promoting microthrombi formation.
  • Ventricular arrhythmia — painful shock discharge increases sympathetic tone, provoking repeated arrhythmic episodes.
What specific antidotes are used for organophosphate poisoning within pathogenetic therapy?

In organophosphate intoxication, specific antidote therapy involves agents aimed at enzyme reactivation. The antidotes used include:

  • Cholinesterase reactivators — restore the activity of inhibited enzymes during poisoning.

Additionally, the mechanism of action of organophosphates is the opposite of atropine, which serves as an example of pharmacological antagonism against acetylcholine.

What is the fundamental difference between pathogenetic and sanogenetic therapy?

Pathogenetic therapy aims to suppress and block the mechanisms of disease development (e.g., breaking vicious cycles). Sanogenetic therapy, conversely, stimulates and potentiates the body's own defense, compensatory, and regenerative forces.

Why is combating the fear of death so important in critical conditions?

The fear of death is an extremely distressing symptom that triggers a massive stress response. This leads to nervous system exhaustion, inappropriate vascular reactions, and worsens the patient's overall critical state.

Which specific adaptive mechanisms are activated during sanogenetic treatment?

Sanogenetic therapy aims to activate four main groups of mechanisms: defense reactions, compensation for lost functions, adaptation to new conditions, and replacement of damaged structures.
