Pediatric Fast Fluid Trial 2

"Participants will administer 900 mL (60 mL/kg) of NS to a model of a 15 kg toddler in shock. The intervention is the mode of administration of the fluid. For the Push-Pull Technique, the 7 cm catheter extension tubing will be connected to one of the three ports of a triple stopcock. A second of the 3 ports of the triple stopcock will be connected to an IV tubing set connected to a 1 L bag of NS. A 60 mL syringe will be connected to the third port of the triple stopcock. On verbal prompt, participants will pull fluid from the bag of NS by withdrawing the plunger of the 60 mL syringe, filling it with saline. They will then toggle the switch of the triple stopcock, so that it is off to the bag of NS and open to IV catheter extension tubing leading to the model. They will then depress the syringe plunger, administering the fluid to the model. These steps will be repeated until each participant believes that they have administered the requested volume of fluid to the model."

"Participants will administer 900 mL (60 mL/kg) of NS to a model of a 15 kg toddler in shock. The intervention is the mode of administration of the fluid. For the Disconnect-Reconnect Technique, the proximal end of the 7 cm catheter extension tubing will be capped with a needleless adapter. The subject will be provided with 60 mL syringes filled with NS, rapidly prepared in real time by an assistant. Syringes will be prepared by withdrawing NS from a 1 L bag via a Gambro Accessory spike. The subject will administer the requested volume of NS to the model by 1. grabbing one of the fluid-filled syringes 2. connecting the fluid-filled syringe to the needleless adapter, and 3. depressing the syringe plunger resulting in administration of the NS to the model. These steps will be repeated until the subject believes they have administered the requested volume of NS to the model. Testing will begin on verbal prompt. The subject and assistant will not be permitted to switch roles."
