Adductor Canal Block Versus Femoral Nerve Block for Analgesia After Anterior Cruciate Ligament Reconstruction Arthroscopically
30. januar 2015 opdateret af: Daqiang Zhao, Shanghai Jiao Tong University Affiliated Sixth People's Hospital
This study aims to compare continuous femoral nerve block with adductor canal block after anterior cruciate ligament reconstruction arthroscopically，especially in the effect on quadriceps strength; and to evaluate which regional anesthesia is more ideal for the patients postoperatively.

Detaljeret beskrivelse
Forty patients with American Society of Anesthesiologists（ASA） Ⅰ-Ⅲ（no limitation of age and gender）are randomized to receive either a continuous adductor canal block(ACB) or a femoral nerve block(FNB) via a catheter (a continuous infusion of 0.2% ropivacaine, 5 mL/h for 48 hours)in the PACU immediately after the anterior cruciate ligament reconstruction arthroscopically.
Patients were under general anesthesia during the operation and received a femoral nerve block with 0.25% ropivacaine 10ml before the surgery.Both groups will receive postoperatively IV patient controlled analgesia (PCA) with morphine (bolus 0.8mg,lock-out time 15 minutes, background infusion 2ml/h)beside the continuous nerve block.
Patients are going to be visited for follow-up on the day of surgery and in the following two days.
Quadriceps strength is assessed with the displacement of patella.VAS at rest time、degree of knee flexion、VAS at 45°flexion of the knee、dose of opioids、whether the patient has sleep disturbance are also recorded.

Eksperimentel: adductor canal block (ACB)
We performed an ultrasound survey at the medial part of the thigh，the needle is introduced in-plane and 2 to 3 mL of saline is used to ensure correct placement of the needle in the vicinity of the saphenous nerve in the adductor canal,the catheter is introduced and advanced 1 to 2 cm beyond the tip of the needle.The study medication is administered as an infusion of 0.2% ropivacaine at a rate of 5mL/h during the next 48 hours.

Aktiv komparator: Femoral nerve block (FNB)
the catheter is inserted in-plane with the probe parallel to the inguinal crease, to obtain a short-axis view of the nerve.
The correct needle placement is confirmed by injecting 2 to 3 mL of saline to cause tissue expansion below the iliac fascia, lateral to the femoral artery, and in the vicinity of the femoral nerve.
The catheter is introduced 1 to 2 cm beyond the tip of the needle，an infusion of 0.2% ropivacaine at a rate of 5mL/h is administered during the next 48 hours.
