hello I'm Brian Johnson and today we're going to use the Claris pal to identify the femoral nerve for a femoral nerve block so you have your probe and you have your clarus app um it's going to be under the nerve pain preset which is already done you have the patient lying sepine and you go to the affected groin region depending upon what injury they have and why you need do the femal nerve block for our purposes today we're going to do the right lower extremity is the affected extremity so what you do is you take your probe and you go to the inguinal crease and basically you're trying to find three structures and stay away from two of them we're staying away from the femoral artery and the femoral vein what you really want to identify is the femoral nerve so I always remember that there are is the an acronym I say Naval nerve artery vein empty and lymph so from lateral to medial you have the nerve the artery the vein empty and lymph Naval so for our purposes today we're finding the femoral nerve which you can see right here the femoral nerves this laterally to the femoral artery you see this pulsatile structure adjacent to it that's the feminal artery lateral to it is this lovely triangular honeycomb structure called the femoral nerve now sitting on top of this is the fascia ilaka and this is really important because when you're doing your nerve block you want to pop under the FASA and provide anesthetic that spreads near the femoral nerve because of ultrasound you can stay far away from the nerve and still provide an appropriate volume of anesthetic safely not damaging or injuring the nerve so once again this is the femoral nerve here honeycomb structure triangular sitting under the fascia ilaka and the femoral artery if you're going to do a femoral nerve block you would do an inplane approach coming in from the left of the screen seeing your needle tip the entire time so femal nerve blocks can be performed blind but with the involvement of of ultrasound it can be more accurate and minimize your complications most notably um damaging the nerve or injecting into the nerve and Arch puncture thank you
