Abstract
The goal of the study was to improve efficiency and safety of the femoral nerve blockade in patients undergoing surgery on lower extremities. Materials and Methods. The ultrasound-guided (US) femoral nerve block was performed using peripheral nerves electrical stimulator in 49 patients. The anesthesia was provided by different volumes of 0,75%, 1%, 1,5%, 2%, 3%, 4% lidocain solution. The characteristic of local anesthetic extent (complete or incomplete surrounding of femoral nerve) were evaluated on the US-device monitor during blockade. The quality of motor and sensory block was assessed within 40 minutes after block. Results. The following minimum amounts of lidocaine allow achieving complete femoral nerve blockade: 0.75% solution - 10 ml; 1% - 7.5 ml; 1.5% - 5 ml; 2% - 5 ml. Conclusion. The minimal value of local anesthetic volume and minimal lidocain amount for achieving the effective femoral nerve block was equaled to 5 ml and 75 mg correspondingly.
