    Intravenous drip


    An intravenous drip - IV drip or IV for short
    is the infusion of fluids into a vein,
    intravenous meaning within veins
    It is administered in medical situations either to replace fluid
    or to provide easy access to the bloodstream for drugs
    It is usually a bag of fluid that is gravity fed
    and thus hangs above the patient

    One common, cheap form of flow control
    is a visible drip chamber
    which also removes air from administration
    and lets staff observe and control the flow rate

    A bag can also be placed into an inflatable cuff
    so that the liquid can be pushed into the patient
    as the cuff is inflated fluid is infused at a higher flow rate
    This is often done with a large bore IV
    meaning that the cannula needle that is inserted
    into the patient´s vein is of a large diameter
    allowing a high flow rate

    Another method is to use an infusion pump
    Infusion pumps allow control over the rate
    and volume of fluid to be given
    and are recommended in any case
    where fine control over intravenous fluids is necessary

    Intravenous fluids are used in a great variety
    of medical conditions
    ranging from dehydration loss of water
    to electrolyte imbalances
    and acute or chronic blood loss

    Beside blood transfusion and intravenous drugs
    there are essentially two types of fluids
    that are used for intravenous drips
    crystalloid and colloid fluids

    "Crystalloids"
    are aqueous solutions of mineral salts
    such as isotonic saline or Ringer´s solution

    "Colloids"
    are solutions of larger molecules such as gelatine

    IV drips have a number of hazards
    More than about 30ml of air
    can lead to a large air embolism clogging
    up the pulmonary circulation
    bringing overall circulation to a stop

    In addition
    if there exists a defect in the heart
    with a right to left shunt
    smaller amounts of air - as little as 2 ml
    can cause an air embolus in the systemic circulation

    An "air embolism" of this sort
    is famously difficult to diagnose
    because it can cause so many different types of symptoms

    A drip placed lower than the patient
    can cause reverse flow
    literally siphoning the bood from a patient

    A nonsterile (i.e. reused) administration set
    can lead to phlebitis, or worse, systemic septicemia

    Finally, an unmeasured flow
    can be to a collapsed vein
    or the tip of the cannula
    can leave the vein
    causing a failure to infuse
    or localized edema


    Note
    that an intravenous drip
    is a sterile medical procedure
    that should only be performed by trained personnel
    under medical supervision, using proper equipment


    Hanging an IV and regulating
    with just a clamp and gravity is tricky but
    "do-able".
    Using standard IV tubing - 10gtt/cc

    100cc/hr = 17gtt/min
    200cc/hr = 34gtt/min
    300cc/hr = 51gtt/min


    If you can just remember that
    17gtt/min = 100cc/hr
    you'll easily be able to figure out different rates
    in your head - or on paper
    Here's a tip courtesy of Shannon DeLuca

    D/H x Q = X

    D=Desired - dosage you wish to give
    H=Have - dosage or strength of concentration the med is available in
    Q= Quantity -preparation in which drug is available


    ie: Order is given for 375mg of Ampicillin p.o. T.I.D

    The label on the RX contains 30ml, 250mg/5ml

    375mg (D)/ 250mg (H) x 5ml (Q) = 7.5ml


    For IV to Gravity
    volume/minutes x drop factor (tubing)= drip rate

    For IV to Pump
    volume/hour = drip volume


    stips to applly the IV drip


    Remove IV administration set and fluid from packaging


    Close infusion rate clamp
    If your set has two spikes for insertion
    into the fluid bag/bottle
    select the appropriate spike and clamp
    the tubing leading to the other spike
    Use vented spikes for non-collapsible bottles
    and non-vented spikes for collapsible bags


    Remove the cover from the selected spike
    and the cover from the bottle/bag of fluid


    Insert the spike into the bottle
    or bag aseptically



    Hang up the bag/bottle
    and invert the pump chamber
    of the administration set
    Open the infusion rate clamp
    and let the pump chamber fill with fluid
    When it is at least partially full turn
    it the right way up
    and let fluid fill the distal tubing


    When fluid drips out of the end of the distal tubing
    turn off the infusion rate clamp



    Squeeze and release the upper drip chamber
    until the fluid level reaches the top of the filter
    The set is now ready for use
