When should the slow IV push of 30 mL 23.4% hypertonic saline be given?

The slow IV push of 30 mL 23.4% hypertonic saline is recommended to be given during situations of shock or respiratory distress. Hypertonic saline is specifically used in combat medicine to rapidly expand intravascular volume and enhance hemodynamic status in patients experiencing severe fluid loss, such as in shock.

When a patient is in shock, particularly from hemorrhage or other traumatic injuries, their blood volume may be critically low, leading to inadequate perfusion of vital organs and systems. Hypertonic saline allows for the rapid mobilization of fluid from the extracellular compartment into the vascular system, improving blood pressure and circulation temporarily. This can provide essential time for further medical intervention while stabilizing the patient.

In respiratory distress, the use of hypertonic saline can also help in certain cases by promoting better oxygen delivery and improving lung function, especially if the patient is experiencing issues related to fluid overload or hypovolemia. Therefore, administering this treatment in these scenarios allows for a targeted and immediate response to critical physiological challenges.
