Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the success rate of a novel ultrasound guided nerve block technique of the lateral femoral cutaneous nerve(LFCN) in anesthetizing the proximal area of cutaneous sensory innervation of this nerve.;Secondary Objective: Presenting a novel nerve block technique Evaluating the area of cutaneous sensory innervation of the LFCN;Primary end point(s): Success rate of anesthesia in the proximal area of the cutaneous sensory innervation of the LFCN after a novel LFCN-nerve block (NB) compared to placebo. The primary endpoint is measured on a straight line through the greater trochanter and the lateral patella (TMP-line) The area of cutaneous sensory innervation is defined by the proximal and lateral area anesthetized by a supra-inguinal fascia iliaca compartment block(FICB).;Timepoint(s) of evaluation of this end point: 30 minutes | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Mean distance from the proximal anesthetized area after NB to the proximal anesthetized area after FICB, measured on the TMP-line. - Mean distance from the proximal anesthetized area after NB to the proximal part of the greater trochanter, measured on the TMP-line. - Mean distance from the proximal anesthetized area after FICB to the proximal part of the greater trochanter, measured on the TMP-line. - Mean distance from the distal anesthetized area after NB to the joint line between femur and tibia - Mean distance from the distal anesthetized area after FICB to the joint line between femur and tibia, on the lateral side of the thigh -Succes rate of the anesthetized area of the NB to completely cover the lines for each of the incisions: Pins, dynamic hip screws, intramedullary nail (3 incisions), anterior approach, anterolateral approach, lateral approach and posterior approach. -Succes rate of the anesthetized area of the NB to partly cover the lines for each of the incisions: Pins, dynamic hip screws, intramedullary nail (3 incisions), anterior approach, anterolateral approach, lateral approach and posterior approach. -Failure rate of the anesthetized area of the NB of covering any part of the lines for each of the incisions: Pins, dynamic hip screws, intramedullary nail (3 incisions), anterior approach, anterolateral approach, lateral approach and posterior approach. - Success rate of the anesthetized after the FICB to completely cover the distal incision for intramedullary nail. - Success rate of the anesthetized area after NB to cross an anterior midline(ASIS-P-line) through the anterior superior iliac spine (ASIS) and the central patella. - Mean distance from the medial-most part of the anesthetized area after the NB to the ASIS-P-line. - Mean maximal-distance measured perpendicular from the TMP-line to the medial part of the anesthetized area after NB - Mean maximal-distance measured perpendicular from the TMP-line to the lateral part | — |
