How to hemolyze your lab samples

On assessment the first arm didn’t have a favorable vein to puncture for ultrasound guided peripheral iv piv insertion because of the nerve bundle covering the left brachial vein and the muscle covering the right brachial vein. I try not to puncture the muscle if I can avoid it but will do it in special circumstances. I checked the contralateral arm and as you can see it had a much more viable vein for ultrasound guided peripheral iv piv insertion. Let me know in the comments what else you’d like to learn. 00:00 - Ultrasound Assessment to disqualify insertion attempt 00:49 - Needle insertion 00:12 - Changing handling of needle allow more range of attack angle real estate 01:30 - Fanning the probe to increase needle visualization 02:14 - Attempting to penetrated the vein 02:20 - “Zero out” the tip of the needle. Pitch up the needle tip to avoid snagging the opposite side of the vein wall to avoid endothelial damage #VirchowsTriad 02:30 - Alternating Probe and Needle advancement to properly guide the needle. Even though the tip of the catheter has snagged the tunica externa it had a hard time perforating through the tunica media. If this happens continue to advance the needle while maintaining the tip of the catheter in the center of the lumen until the vein finally “pops” and releases elastic tension from the successful perforation into the lumen of the vein. 02:40 - How to steady probe hand. More points of contact on a fixed surface will increase stability, like a camera tripod. 04:00 - Endothelial snag 04:18 - Advancing the catheter 04:40 - Troubleshooting suspiciously low flashback in catheter hub 04:50 - No blood return/Troubleshooting catheter by pulling back 05:10 - Assessing vein and catheter longview to troubleshoot 05:54 - Visualization of the catheter resting into the base of a venous valve 06:50 - Possible tissue damage from over pressuring the base of the valve during flush against resistance 07:35 - Vector change of the vein making it impossible to pitch up any further without rotating the needle 08:10 - Reflecting on how to improve insertion next procedure. Threading the whole needle is important.
