Clinical Trial[Combined sciatic and inguinal paravascular nerve block: a valid alternative for arthroscopic knee surgery].
To assess the effectiveness of a combined transgluteal sciatic and inguinal paravascular nerve block for arthroscopic knee surgery. ⋯ The combined sciatic and inguinal paravascular block is effective for arthroscopic knee surgery and offers an alternative when other anesthetic techniques cannot be used. Use of a pressure cuff may require complementary sedation.

Local anesthetic blocks have been used in a variety of ways in the management of headache. Some practitioners use blocks of the supraorbital and greater occipital nerves as a form of treatment. Although the effect of each block is limited in duration, a series of injections appears to provide sustained relief. ⋯ On the other hand, blocks can be used to diagnose cervical sources of headaches. When performed under controlled conditions, such blocks can identify cervical sources of pain in a substantial proportion of patients with headache after whiplash. Positive blocks also predict good outcome from radiofrequency neurotomy of the nerve blocked.

Sciatic nerve blocks through lateral approaches in the popliteal fossa have been proposed. We describe a new medial approach to the sciatic nerve at this level. ⋯ We describe a new medial approach to the sciatic nerve in the popliteal fossa. More studies will be required to demonstrate the technique is effective and safe.

Case Reports
Can peripheral nerve blocks contribute to heel ulcers following total knee replacement?
Peripheral nerve blocks are widely used for postoperative analgesia following total knee replacement. We would like to present three cases of heel ulcers encountered following a peripheral nerve block for knee replacement surgery. ⋯ Attention needs to be given to the pressure points in the foot after the nerve blocks. Awareness of this uncommon complication is necessary to prevent its occurrence.
