Sciatic nerve block made easy for resident trainers

Lateral Supratrochanteric Approach to Sciatic and Femoral Nerve Blocks in Children: A Feasibility Study

“…This fact suggests that supratrochanteric SNB and FNB can be performed with a standard 15 cm insulated needle virtually in all children. Abd el motlb et al [ 42 ] reported that the sciatic nerve lies at the depth of 70 ± 8 mm in the transgluteal approach, and it is more superficial than in the lateral supratrochanteric approach in our study. We did not find studies about the femoral nerve depth in the classic FNB technique, but it is reasonable to assume that the skin to nerve distance with classic FNB is less than that in our work.…”

“…Time and number of attempts to perform lateral supratrochanteric SNB in our study were at least not higher compared to these variables in other studies. Other authors report that it took 5 ± 3 minutes [ 43 ] or 2 (1–5) minutes [ 44 ] for performing parasacral SNB and 3 (1–10) minutes [ 44 ] or 3–3.5 minutes [ 42 ] for performing transgluteal SNB. It took 2–10 attempts to perform Labat transgluteal SNB by trainees [ 42 ].…”

It took 2–10 attempts to perform Labat transgluteal SNB by trainees [ 42 ]. There are no scientific data about procedure time and number of needle passes for performing the classic FNB.…”

“…Clinical efficacy of classic parasacral SNB varies through studies and can be 97% in neurostimulator-guided SNB [ 30 ] and 100% in ultrasound-guided SNB [ 43 , 45 ]. The success rate of the Labat transgluteal approach varies between 90% [ 42 ] and 96% [ 46 ]. The success rate of neurostimulator-guided classic approach FNB was 92% [ 35 ].…”
