Overview
Skin donor sites in patients undergoing split-thickness skin grafting surgeries can be very painful postoperatively. This site is most often the anterolateral thigh, the pain at which location can traditionally be covered by a fascia iliaca nerve block, although that comes with the disadvantage of losing motor functions in the femoral nerve distribution. The LAM nerve block, which is relatively new, aims to provide analgesia in the distribution of the lateral and anterior femoral cutaneous nerves. In short, this nerve block would decrease the sensation of the anterolateral thigh area without affecting the motor function of the leg. Investigators aim to study the consistency and coverage size of sensation changes by mapping out the area after the block in each patient.
Primary outcome measures
- Area of sensory change after nerve block [Time frame: 20 min after nerve block placement]
