Regional Anesthesia for Achilles Tendon Repair

Recommended Regional Block Techniques

Single-shot or continuous peripheral nerve blocks using lower concentrations of local anesthetic without adjuncts are recommended for Achilles tendon repair, as they provide effective analgesia without delaying diagnosis of potential complications like acute compartment syndrome 1, 2
Single-shot blocks should use lower concentrations of local anesthetic (bupivacaine or ropivacaine 0.1-0.25%) to maintain some sensory function 3, 4

Avoid dense blocks of long duration that significantly exceed the duration of surgery 1, 2
Amide local anesthetics (lidocaine, bupivacaine, ropivacaine) are preferable to ester types for regional blocks 5

Use caution with adjuncts as they can increase block density and duration 3
If prolonged analgesia is required, consider lower concentration continuous techniques rather than dense single-shot blocks with adjuncts 2

Achilles tendon repair carries risk of ACS, which requires vigilant monitoring 1, 3
Post-injury and postoperative surveillance should include regular assessment for signs and symptoms of ACS by trained healthcare staff 1, 2
Use objective scoring charts to monitor for ACS 1, 2
Equipment for measuring intracompartmental pressure should be available on wards caring for these patients 1

In children, low concentrations of local anesthetic (bupivacaine or ropivacaine 0.1-0.25% for single shot and 0.1% for continuous nerve blocks) can be used safely 3
Proper monitoring systems should be in place to recognize ACS in children 3

Obtain informed consent specifically addressing the choice of analgesic technique 1, 2
Avoid neuraxial blocks (spinal, epidural) as they may exacerbate hemodynamic instability and carry risks of coagulopathy in trauma patients 5
If neuraxial techniques are used, they should be based on local anesthetics only, without opioid additives, to minimize respiratory depression 5
Military experience suggests that continuous peripheral nerve blocks with low-dose local anesthetic solutions can be used safely even in high-energy injuries at risk of ACS 4
Ensure proper ventilation and oxygenation monitoring during the surgical procedure regardless of anesthetic technique 5
