Please Help me with Tonicity of IV Fluids

  1. Hello Friends,

    How are you all doing?

    I am confused about the tonicity in IV solutions. In this, I specially get more confused in when to use D5W, 1/2 NS, D5 1/2 NS, and D5 NS?

    Thank you all for your help!

    I have given you several resources and IVF charts that will help you.
    Almost all circulatory shock states require large-volume IV fluid replacement, as does severe intravascular volume depletion (eg, due to diarrhea or heatstroke). Intravascular volume deficiency is acutely compensated for by vasoconstriction, followed over hours by migration of fluid from the extravascular compartment to the intravascular compartment, maintaining circulating volume at the expense of total body water. However, this compensation is overwhelmed after major losses. See Fluid Metabolism for maintenance fluid requirement discussion, and see Dehydration and Fluid Therapy in Children for mild dehydration discussion.

    Choice of resuscitation fluid depends on the cause of the deficit.Intravenous Fluid Resuscitation: Shock and Fluid Resuscitation: Merck Manual Professional
    not that I am a big wiki fan...this is pretty good.
