This study aims to determine temperature effect on nerve conduction block induced by high-frequency (kHz) biphasic stimulation (HFBS). ⋯ Temperature has an important influence on HFBS-induced nerve block. The blocking mechanisms underlying acute and poststimulation nerve blocks are likely to be very different.

Case Reports
Ultrasound-guided brachial plexus nerve block in a patient with a left palmar schwannoma: A case report.
Ultrasound-guided brachial plexus block is a common anesthetic procedure used in upper extremity surgery. However, it may not be a suitable option for some patients. ⋯ Even if there is painless when skin-cutting after implementation of brachial plexus block, the patient is painful when pulls the nerve around the tumor during excision. It is necessary to give an analgesic drug or anesthetize a single terminal nerve as a supplement for brachial plexus block in patients with schwannoma.

Peripheral nerve block is a common anesthetic technique used during orthopedic upper limb surgery. Injection of local anesthetics around the target nerve inhibits the action of voltage-dependent sodium channels, inhibiting neurotransmission of pain impulses and providing motor immobility. Compared to general anesthesia, it could improve functional recovery by inhibiting nociceptive impulses and inflammation, thus reducing postoperative pain and immobilization and improving postoperative rehabilitation. This systematic review evaluates the impact of peripheral nerve block versus general anesthesia on postoperative functional recovery following orthopedic upper limb surgery. ⋯ Current literature is limited and fails to identify the benefit of peripheral nerve block on functional recovery. More studies are needed to assess the impact on long-term recovery. Considering the potential impact on clinical practice and training, a prospective study on functional recovery is ongoing (NCT04541745).
