简要总结
The effect of perineural dexamethasone administered as an adjuvant in prolonging the duration of analgesia continues to be under debate. The investigators performed a prospective randomized study to evaluate the effect of perineural dexamethasone in different concentrations in postoperative analgesia in femoral nerve block for anterior cruciate ligament reconstruction.
详细描述
After Ethics committee approval, 75 patients American Society of Anesthesiologists score (ASA) I-III were randomized at the end of surgery into 3 groups of 25 patients each who underwent femoral nerve block: group A with 20 ml ropivacaine 0,5% and 20 ml lidocaine 1%; group B with 20 ml ropivacaine 0,5%, 20 ml lidocaine 1% and 4 mg dexamethasone; group C with 20 ml ropivacaine 0,5%, 20 ml lidocaine 1% and 8 mg dexamethasone.
All groups received postoperative analgesia when visual analog scale (VAS) over 3 (by request), with IV Perfalgan 1 g and morphine (loading dose 0.1 mg/kg and titration until VAS under 3, followed by subcutaneous (SC) administration of 1/2 of total loading dose on demand for the following 24 hours (h) .
Efficacy was evaluated by the time interval from performing the block until the first analgesic dose required, the total amount of morphine in the first 24 h postoperative, the patient satisfaction and the neurological side effects.

研究组 & 干预措施
Group A
After the spinal anesthesia regressed, the investigators performed a single shot femoral block with ropivacaine 0,5% 200 mg + lidocaine 1% 200 mg. After the block regression, at the first analgetic request the patients received the analgesia protocol was started for 24 h with paracetamol 1 g IV every 8 h and lornoxicam 8 mg PO every 12 h; if VAS was still over 3 after 30 min, morphine was given as a loading bolus of 0.1 mg/kg IV supplemented with 2 mg IV every 5 minutes until VAS <3. After 2 h morphine was administered SC ½ of the total loading dose at request.
