Hypertonic Saline (3%) infusion calculator It allows users to determine “the approximate compartmental volume increases utilizing various maintenance solutions” based on the type of solution used (normal saline, D5W, 0.45NS, or D5 0.45NS) and the volume of solution used (expressed in ml).įor a 220 lb male with a current sodium level of 108 meq/L, the calculator returns the following values: ![]() Using this patient data, the calculator also computes estimated body water compartment volumes. However, some sources state that faster infusion rates may be used in known acute conditions such as hyponatremia that has persisted for less than 24-48 hours.”). The maximum sodium increase within the first 24 hours should not exceed 10 to 12 meq/liter or <20-25 meq/L over 48 hours. Rapid correction of low sodium can lead to osmotic demyelination of the brain / brainstem. The calculator also computes the infusion rate for normal saline (0.9%), which is preferred in cases of “mild to moderate hyponatremia (serum sodium: 125-134 meq/L).” Users can set a target sodium level of 135 meq/L or 140 meq/L, and set a maximum rate of increase of 0.5-2.0 meq/L/hour (an important factor to consider because, as noted by the authors of this resource, “Hyponatremia of unknown duration - maximum recommended rate of infusion is 0.5 meq/L/hr. The calculator “determines the rate necessary to increase the serum sodium at 0.5 meq/L/hr” until the specified target sodium level is reached. The calculator then automatically computes the infusion rate for hypertonic saline (3%), which is “usually reserved for severe hyponatremia (sodium < 115 meq/L),” in order to reach a target level of 120 meq/L or 125 meq/L. The Hypertonic and Normal Saline Infusion Calculator from GlobalRPH allows users to enter a patient’s weight (in lbs or kg), gender (male, female, elderly male, elderly female), and current sodium level (expressed as meq/L). ![]()
