Normal saline (0.9% sodium chloride)

Fluid resuscitation, pediatric bolus limits, and nebulized saline are different uses.

OCEMS source summary · Updated 2026-09-16

Check before giving

  • Reassess lung sounds and perfusion before more fluid. Avoid transferring sepsis fluid instructions into cardiogenic pulmonary edema.
  • PR-205 directs immediate base contact without fluids for pediatric cardiogenic shock with pulmonary edema.

Use in OCEMS

  • Used in multiple poor-perfusion/hypovolemia pathways and as a diluent or flush where a procedure specifies it.
  • Do not apply a universal fluid limit to every condition: hemorrhage/TBI, sepsis, cardiac, and pediatric pathways have different instructions.

Adult / adolescent

Indication / routeDose & limits
Common medical resuscitation pattern250 mL IV boluses, reassessing between doses, up to 1 L in the relevant medical standing order. Observe any clear-lung/no-CHF condition.
Traumatic hemorrhage / TBISO-T-005 gives separate ongoing-infusion and BP targets. Use that condition-specific pathway rather than assuming a universal 1 L ceiling.

Pediatric

  • Many pediatric orders specify 20 mL/kg IV/IO, maximum 250 mL per bolus, and base contact; up to 3 total boluses under the applicable standing order.
  • SO-P-080: if pressure does not improve after the first bolus, continue indicated fluid resuscitation and request a pediatric push-dose epinephrine order.
  • Croup-like barking cough in SO-P-035: 3 mL normal saline by continuous nebulization as tolerated. This is an inhalation dose, not a fluid-resuscitation dose.

Pediatric weight table — Poor perfusion / hypotension bolus

  • Source: SO-P-080. Dose rule: 20 mL/kg; route: IV/IO.
  • 20 mL/kg IV/IO, maximum 250 mL per bolus. SO-P-080 permits two repeats for three total boluses, with reassessment.
  • Make base contact. If BP does not improve after the first bolus, request the pediatric push-dose epinephrine order while continuing indicated fluid resuscitation.
  • This table is for the SO-P-080 shock bolus. Other indications have their own limits; PR-205 directs no fluid bolus when cardiogenic shock presents with pulmonary edema.
  • Calculated examples for the exact weights shown, using the named standing-order/procedure formula. Do not round the patient’s weight to the nearest row. For another weight, calculate from the stated formula and apply the limits. These are not the rounded I-20 weight-band volumes.

Preparation & reassessment

  • Verify IV versus preservative-free nebulizer product and the intended route.
  • Record each bolus volume, cumulative volume, BP, respiratory findings, and response. Use the specific pediatric order for maximums and repeat count.
