Randomized Controlled Trial
Analgesic efficacy of ultrasound-guided adductor canal blockade after arthroscopic anterior cruciate ligament reconstruction: a randomised controlled trial.
Anterior cruciate ligament (ACL) reconstruction surgery is associated with moderate to severe postoperative pain, which may be ameliorated by peripheral nerve blocks. The adductor canal block (ACB) is an almost exclusively sensory nerve block that has been demonstrated to reduce pain and opioid consumption after major knee surgery. ⋯ An analgesic regimen with paracetamol and ibuprofen provides acceptable postoperative pain control after arthroscopic ACL reconstruction. ACB did not confer further benefit in our patients.

Randomized Controlled Trial Comparative Study
Ultrasound-guided transversus abdominis plane block in children: a randomised comparison with wound infiltration.
The transversus abdominis plane (TAP) block is a new regional anaesthesia technique applicable to infants and children. ⋯ Ultrasound-guided TAP block with high volume (0.5 ml kg) 0.25% levobupivacaine provides prolonged postoperative analgesia and reduced analgesic use without any clinical side-effects after unilateral hernia repair in children.

Pupillary reflex dilation appears to be a reliable indicator of response to noxious stimulation even under general anaesthesia. The ability of pupillometry to detect the effects of extremity blocks during continuous infusion of opioids remains unknown. ⋯ These results are a proof of concept. The effects of peripheral nerve block can be detected via the measurement of pupillary reflex dilation response to noxious stimulation of the skin in patients receiving remifentanil.
