    Intravenous fluid requirement calculations 

    One common problem encountered by medical students, nursing students and sometimes even to practicing doctors is intravenous (iv) fluid calculation.

    There may be various ways to determine how much maintenance fluid to be given intravenously, however the author will discuss here one commonly practiced technique practiceed by certain medical practitioners.

    First you should be oriented with the formula depicted below in the diagram –

    To explain the above diagram –

    -For body weight of first 10 kgs we give 100 ml/ kg / day.

    -For the next 10 kgs we give 50 ml / kg / day.

    -Finally, for the remaining body weight i.e. for those weighing more than 20 kgs we give in the rate of 20 ml / kg / day.

    For easy calculations it’s good to memorize the amount of iv fluids which might be needed for an individual weighing 10 and 20 kgs.

    For a 10 kg person iv fluid required is 10×100 =1000

    For a 20 kg person iv fluid requirement is –
    1000 + (10×50)= 1500.

    If you remember the above two values you can easily derive iv fluid requirements for various body weights more than 10 and 20 kgs.

    Now let us consider some examples –

    For a 8 kg child- 8×100= 800 ml per day.

    For a 12 kg child – 1000+ (2×50) = 1100 ml per day.

    For a 30 kg individual – 1500+ (10×20)= 1700 ml per day.

    Lastly, how to determine how much iv fluid to be given in each hour. For this simply divide ➗ the calculated total fluid requirement per day by 24; since 24 hours makes a day.

    The above writing is a simplified version for iv fluid requirement calculation made by the author which may not be free from errors. Hence, please cross check the information from reliable sources. ⚠

    When should you avoid intravenous cannulation ? 

    As such there is no absolute contraindications for doing an intravenous cannulation . 

    When its difficult to access the vein we can take the help of ultrasound and do the intravenous cannulation  process ultrasound guided.

    However in certain situations iv cannulations are avoided like-

    1. When there is skin infection or rash on the site we want to cannulate, its better to avoid the affected area and do at another site.
    2. When doctor plans to start hemodyalisis for some reason, iv cannulation is avoided in one of the hands to make a fistula between the artery and vein.

    Chronic kidney disease (CKD) and intravenous cannulation 

    DSC_0635CKD patients are likely candidates who will probably require hemodyalisis in future. To perform a hemodyalisis an arteriovenous shunt is required.

    Therefore, treating physicians must keep this thing in mind and avoid unnecessary intravenous cannulations so that good veins can be preserved for arteriovenous shunt purposes.

    One should not forget the importance of hemodyalisis in CKD patients.
