The investigators hypothesize peripheral intravenous cannulation (insertion of tube into vein) will be facilitated (decreases the number of attempts) by a passive leg raise (raising the legs at the hip to 45 degree in a child laying on their back) in children.
Establishing peripheral intravenous (PIV) access in the pediatric population is challenging even in the hands of skilled practitioners. A passive leg raise (PLR), raising a patient's legs to a 45 degree angle while supine, auto-transfuses the blood volume within the patient's lower extremities into the central venous compartment. Increasing the blood volume in the central venous compartment may also increase the volume and caliber of upper extremity peripheral veins. It remains to be studied whether a PLR increases peripheral vein diameter and if this would facilitate the placement of PIVs in the pediatric population.

A passive leg raise (PLR) is defined as raising a patient's legs to a 45-degree angle at the hip while supine.

The number of attempts to successful catheterization.
The study's primary outcome (number of peripheral IV attempts) will be analyzed using a Chi-square test.
Time frame: During the intraoperative procedure.
The mean change in peripheral vein diameter following passive leg raise, assessed on ultrasonography.
The change, if any, in peripheral vein diameter will be measured by comparing the diameter assessed by ultrasound at baseline and following leg raise. Results will be compared using the student's t test.
Time frame: During the intraoperative procedure.
Time from skin puncture to the confirmation of a functioning peripheral line.
Time to vein cannulation will be compared using the student's t test.
Time frame: Measured intraoperatively, an expected estimated average of 2 minutes.
Provider perception of PLR on vein visualization.
Chi-square testing will be used to evaluate provider perception of passive leg raise on vein visualization and palpation.
Time frame: Immediately following successful cannulation in the experimental group.
Provider perception of PLR on vein palpation.
Chi-square testing will be used to evaluate provider perception of passive leg raise on vein visualization and palpation.
Time frame: Immediately following successful cannulation in the experimental group.
