Often used in severe cases of shock, unresponsiveness and cardiac arrest since they are HUGE and relatively easy to cannulate. ? Why are they not monly used in those who are conscious ? ? Why are they not a good choice for patients of multi system trauma ? EJ cannulation procedure ? Place patient supine / slight reverse Trendelenburg ? Why ??? ? Turn patients head slightly to opposite side ? Cleanse with antiseptic using universal precautions ? Create tourniquet effect with fingers by applying light pressure to the inferior aspects of the EJ being cannulated. Procedure ? Aim needle towards ipsilateral nipple ? Insert needle and enter vein ? Observe flashback ? Withdraw needle and attach IV tuning ? Cover site with sterile dressing EJ cannulation Calculating flow rates Drip sets Factor 10 gtt/ml (macro) 10 drops = 1 ml 6 15 gtt/ml 15 drops = 1 ml 4 20 gtt/ml 20 drops = 1 ml 3 60 gtt/ml (micro) 60 drops = 1 ml 1 Volume to be administered (ml) Time to be infused (min) X Drip set (gtts/ml) = Drops/min (gtts/min) Calculations ? Your patient is to receive 1000 ml of normal saline (NS) over a 12 hour period using a microdrip (60 gtt/ml) administration set. The formula will now look like this: Volume to be administered (ml) Time to be infused (min) X Drip set (gtts/ml) = Drops/min (gtts/min) 1000 ml 720 min X 60 gtts/ml = Drops/min (gtts/min) = Drops/min (gtts/min) Now add medications ? A physician orders 2 mg/min of Lidocaine to your patient. She orders 2 g of lidocaine to be added to 500 ml NaCL. Using a 60 gtt/ml set, calculate the gtt/min. Calculation [ ] = Mass Volume = g 500 ml = 2022 mg 500 ml = 4 mg/ml Dose = D H X V = 2 mg/min 2022 mg = 1000 mgml/min 2022 mg = ml/min X 500 ml Calculation Volume to be administered (ml) Time to be infused (min) X Drip set (gtts/ml) = Drops/min (gtts/min) ml 1 min X 60 gtts/ml = Drops/min (gtts/min) 30 = Drops/min (gtts/min) A Variation to the Same Volume (ml) On Hand (mg) X Drip set (gtts/ml) = Drops/min (gtts/min) = Drops/min (gtts/min) 30 = Drops/min (gtts/min) X Ordered (mg/min) 500 ml 200 mg X 60 gtt/ml X 2 mg/mi
