Summary

Hypertonic saline solutions (HSS) effectively manage hypovolemic shock by increasing plasma volume and reducing vascular resistance. Further clinical studies are needed to confirm HSS benefits over colloids for broader applications.

Area of Science:

  • Physiology
  • Pharmacology

Context:

  • Hypertonic saline solutions (HSS) are utilized for managing hypovolemic shock.
  • The standard HSS is 7.5% sodium chloride (2,500 mOsm.L-1), used alone or with colloids.

Purpose:

  • To review the haemodynamic effects of HSS.
  • To discuss the clinical relevance of HSS in various shock conditions.

Summary:

  • HSS increases preload via plasma volume expansion and vasoconstriction, and decreases afterload by reducing systemic vascular resistance.
  • While myocardial stimulation occurs, its clinical significance is uncertain.
  • Hemorrhagic shock is a primary indication; potential uses include perioperative volume replacement, septic shock, burn injury, and CPR.

Impact:

  • HSS demonstrates significant haemodynamic effects beneficial in hypovolemic and hemorrhagic shock.
  • Further clinical research is essential to validate HSS efficacy compared to colloids for expanded clinical use.
