<p begin="00:00:12.631" end="00:00:14.687" style="s2">popliteal nerve block.</p>
<p begin="00:00:14.687" end="00:00:17.850" style="s2">The target depth is<br />approximately 2 to 4 centimeters</p>
<p begin="00:00:17.850" end="00:00:20.373" style="s2">in an 80 kilogram adult.</p>
<p begin="00:00:20.373" end="00:00:23.568" style="s2">The patient is positioned in<br />a lateral decubitus position</p>
<p begin="00:00:23.568" end="00:00:26.091" style="s2">with the hip and knee slightly flexed.</p>
<p begin="00:00:26.091" end="00:00:28.135" style="s2">The transducer is placed transversely</p>
<p begin="00:00:28.135" end="00:00:31.135" style="s2">on the popliteal skin<br />crease with the orientation</p>
<p begin="00:00:31.135" end="00:00:33.388" style="s2">marker directed laterally.</p>
<p begin="00:00:33.388" end="00:00:36.393" style="s2">The transducer should be<br />moved medially and laterally</p>
<p begin="00:00:36.393" end="00:00:40.222" style="s2">to identify the dark round<br />pulsatile popliteal artery.</p>
<p begin="00:00:40.222" end="00:00:43.492" style="s2">The compressible poplital<br />vein can be seen superior</p>
<p begin="00:00:43.492" end="00:00:45.695" style="s2">to the popliteal artery.</p>
<p begin="00:00:45.695" end="00:00:49.145" style="s2">The tibial nerve lies<br />superficial to the popliteal vein</p>
<p begin="00:00:49.145" end="00:00:52.668" style="s2">and appears as a bright<br />hyperechoic oval structure.</p>
<p begin="00:00:52.668" end="00:00:55.331" style="s2">The transducer should be slowly translated</p>
<p begin="00:00:55.331" end="00:00:57.926" style="s2">up the posterior thigh<br />to identify the point</p>
<p begin="00:00:57.926" end="00:01:00.976" style="s2">where the peroneal and tibial nerves join.</p>
<p begin="00:01:00.976" end="00:01:04.783" style="s2">The ideal point for needle<br />insertion is at or just below</p>
<p begin="00:01:04.783" end="00:01:07.763" style="s2">the split of the tibial<br />and peroneal nerves.</p>
<p begin="00:01:07.763" end="00:01:11.138" style="s2">The needles is advanced<br />using an in-plane technique.</p>
<p begin="00:01:11.138" end="00:01:14.455" style="s2">The needle is positioned<br />1 to 2 centimeters lateral</p>
<p begin="00:01:14.455" end="00:01:18.534" style="s2">to the transducer and<br />advanced under the transducer.</p>
<p begin="00:01:18.534" end="00:01:20.831" style="s2">The initial end point for<br />the needle is immediately</p>
<p begin="00:01:20.831" end="00:01:22.906" style="s2">beside the tibial nerve.</p>
<p begin="00:01:22.906" end="00:01:25.326" style="s2">Local anesthetic should<br />be principally injected</p>
<p begin="00:01:25.326" end="00:01:27.880" style="s2">around the tibial nerve,<br />as it is responsible</p>
<p begin="00:01:27.880" end="00:01:31.963" style="s2">for the majority of the<br />innervation of the foot.</p>
