Definition

1. Noun:
   • A serious medical condition: Sepsis is a life-threatening condition that arises when the body's response to an infection causes injury to its own tissues and organs.
   • The presence of harmful microorganisms or their toxins: Specifically, it involves the presence of pus-forming bacteria or their toxins in the blood or tissues, leading to a systemic inflammatory response.

Usage

Sepsis is a medical term used to describe a severe, body-wide infection that has spread via the bloodstream. It is a critical condition that requires immediate medical attention. The term is typically used in clinical, healthcare, and scientific contexts.

Examples

• Noun:
  • The patient was admitted to the ICU with severe sepsis.
  • Early diagnosis and treatment of sepsis are crucial for survival.
  • The infection led to sepsis, complicating her recovery.

Advanced Usage

• "Septic shock": A severe and often fatal form of sepsis characterized by very low blood pressure that does not respond adequately to fluid replacement.

  • The progression from sepsis to septic shock significantly increases mortality risk.

• "Neonatal sepsis": Sepsis occurring in newborn infants, particularly within the first month of life.

  • Screening protocols are in place to detect neonatal sepsis early.

Variants and Related Words

• Septic (adj): Relating to or caused by sepsis; infected with microorganisms.

  • The wound became septic and required aggressive antibiotic therapy.

• Asepsis (n): The state of being free from disease-causing microorganisms.

  • Surgical asepsis is essential to prevent postoperative infections.

Synonyms

• Blood poisoning (informal): A non-technical term sometimes used to refer to sepsis.
• Septicemia: A specific condition where bacteria are actively multiplying in the bloodstream, often used interchangeably with sepsis, though technically a subset.

Related Phrases and Terms

• Systemic inflammatory response syndrome (SIRS): A clinical syndrome often associated with sepsis, involving a widespread inflammatory state.

  • The diagnosis of sepsis requires evidence of infection along with signs of SIRS.

• Bacteremia: The presence of bacteria in the blood, which can lead to sepsis but is not synonymous with it.

  • Not all cases of bacteremia progress to sepsis.
