Objective  To explore the clinical effect and complications of lumbar plexus block through different approaches on perioperative analgesia in aged proximal femur surgery, and find the best method for analgesia in these patients. Methods  From January to December 2015, 150 elderly patients scheduled for proximal femur surgery were randomly divided into three groups: psoas compartment block (PCB group, n=50), Winnie " 3 in 1” block (Winnie group, n=50), and fascia iliaca compartment block (FICB group, n=50). Twelve hours before surgery, guided by ultrasound and nerve stimulator, lumbar plexus blocks were performed in all the patients, then patient-controlled analgesia (the formula and the usage were the same) was done. All patients received epidural anesthesia, and were maintained postoperative analgesia for 72 hours. If Rest Visual Analogue Scale>3 or Initiative Movement Visual Analogue Scale>4, sufentanyl 10 μgi.m. was given. Muscle strength grades and complications were recorded. Anesthetic effect of sensory block of femoral, lateral femoral cutaneous, and obturator nerves were measured and recorded too. Results  There were two cases of epidural block, and one case of puncture point bleeding in group PCB; no complication in the other groups was found. There was no remedy for inadequate analgesia in the three groups. Compared with group PCB, the muscle strength grades during postoperative 24–72 hours in group FICB were higher (P<0.05). The successful rate of the block of lateral femoral cutaneous nerves was 64%, 91% and 96% in group Winnie, group PCB and group FICB, respectively, and the differences between the three groups were all statistically significant (P<0.05). The successful rate of the block of obturator nerves in group FICB (62%) was lower than that in group PCB (89%) and Winnie group (84%) (P<0.05). Conclusion  Continuous fascia iliaca compartment block on perioperative analgesia in aged proximal femur surgery, with exact effect, less complications and simple operation, is better than the psoas compartment block and Winne " 3 in 1” nerve block.
