Clinical Trial Summary

The interaction of analgesia and sedation ot their effect on the prognosis of surgical patients still need to be elucidated.Currently, how to optimize intra-operative Analgesia and sedation to improve the prognosis of surgical patients is still a mystery.Intra-operative nerve block provided regional analgesia of the operated knee, which reduced the dosages of sedatives and analgesics.Based on a pilot study,the investigators found a decrease of post-operative adverse composite outcomes with the use of continuous femoral nerve block (2% versus 7%) ,therefore, the investigators postulate that general analgesia with lighter sedation in combination with peripheral nerve block could reduce the post-operative morbidity compared with deeper sedation.This randomized controlled trial is designed to test this hypothesis in patients receiving unilateral knee arthroplasty.


Description:

This study was approved by the institutional review board of the First Affiliated Hospital of Chongqing Medical University. The protocol design is in accordance with Consolidated Standards of Reporting Trials (CONSORT) statement.This study is designed as a randomized controlled trial to compare intra-operative continuous femoral nerve block combined with lighter anesthetic depth (group L) with deeper anesthetic depth (group D) monitored by bispectral index (BIS). All potentially eligible participants will be asked to give written informed consent before they are enrolled in this study.The following outcomes will be assessed:post-operative major complications (post-operative pulmonary infection,need of mechanical respiratory support,myocardio-infarction,deep venous thrombosis, pulmonary embolism, stroke, poor wound healing,all-cause post-operative death within 30 days).Secondary Outcomes included :acute post-operative pain assessed by visual analogue scale and dosages of rescue medications;Dosages of intra-operative vasopressors,anesthetics and analgesics;Life quality measured by EQ-5D questionnaire 3 months post-operatively;adverse events associated with the femoral catheter (displacement, infection, hematoma,drop-out of catheter).

Intervention

Procedure:
peri-operative continuous femoral nerve block with light sedation
this technique will be administered to participants in group L .The puncture site was identified using ultrasound guidance (2 cm distal to the inguinal ligament, and 1 ~2 cm lateral to the femoral artery).2% lidocaine was used for topical anesthesia, then an insulated needle (Contiplex B Braun, Melsungen, Germany) (20 G*45 mm,short bevel,30°) was connected to the nerve stimulator(Innervator,Fisher &Paykel,New Zealand).The parameters were as follows: stimulating intensity of 1 mA at a rate of 2 Hz. The needle was advanced at 30°~45° angle to the skin, until quadriceps femoral muscle twitches were elicited. Its position was accepted if contractions were still elicited when an output equal to 0.3 mA.The participants will receive continuous femoral nerve block intra-operatively and post-operatively till 3 days post-operatively.The depth of anesthesia will modulated at 50-60 with BIS monitoring
post-operative continuous femoral nerve block
this technique will be administered to participants in group D .The puncture site was identified using ultrasound guidance (2 cm distal to the inguinal ligament, and 1 ~2 cm lateral to the femoral artery).2% lidocaine was used for topical anesthesia, then an insulated needle (Contiplex B Braun, Melsungen, Germany) (20 G*45 mm,short bevel,30°) was connected to the nerve stimulator(Innervator,Fisher &Paykel,New Zealand).The parameters were as follows: stimulating intensity of 1 mA at a rate of 2 Hz. The needle was advanced at 30°~45° angle to the skin, until quadriceps femoral muscle twitches were elicited. Its position was accepted if contractions were still elicited when an output equal to 0.3 mA.The participants will receive continuous femoral nerve block post-operatively till 3 days post-operatively.The depth of anesthesia will modulated at 30-40 with BIS monitoring
