Perineural Dexmedetomidine Reduces the Median Effective Concentration of Ropivacaine for Adductor Canal Block

Adductor Canal Block for Knee Surgeries: An Emerging Analgesic Technique

In recent years, adductor canal block (ACB) has been introduced as an alternative for femoral nerve block with a great advantage of preserving or minimally reducing quadriceps strength. The technique is relatively easy and is performed under ultrasound guidance. Despite growing evidence regarding efficacy and safety of ACB following knee surgery, use of ACB is still limited to high volume ortho...

Perineural Dexmedetomidine as an Adjuvant Reduces the Median Effective Concentration of Lidocaine for Obturator Nerve Blocking: A Double-Blinded Randomized Controlled Trial

UNLABELLED Research suggests that the addition of dexmedetomidine to local anesthetics can prolong peripheral nerve blocks; however, it is not known whether dexmedetomidine can reduce the quantity of local anesthetic needed. We hypothesized that adding dexmedetomidine as an adjuvant to an obturator nerve block could reduce the median effective concentration of lidocaine. In this double-blinded ...

Perineural administration of dexmedetomidine in combination with ropivacaine prolongs axillary brachial plexus block.

To evaluate the hypothesis that adding dexmedetomidine to ropivacaine prolongs axillary brachial plexus block. Forty-five patients of ASA I~II and aged 25-60 yr who were scheduled for elective forearm and hand surgery were randomly divided into 3 equal groups and received 40 ml of 0.33% ropivacaine + 1 ml dexmedetomidine (50 μg) (Group DR1), 40 ml of 0.33% ropivacaine + 1 ml dexmedetomidine (10...

Adductor Canal Block for Knee Surgeries: An Emerging Analgesic Technique.

Comparison of Adductor Canal Block and Femoral Nerve Block for Postoperative Pain in Total Knee Arthroplasty

A total knee arthroplasty (TKA) has always been associated with moderate-to-severe pain. A systematic review of randomized controlled trials (RCTs) and non-RCTs was performed to evaluate the efficacy and safety of pain control of adductor canal block (ACB) and femoral nerve block (FNB) after TKA.Relevant literatures about the ACB and FNB after TKA for reducing pain were searched from Medline (1...
