UNLABELLED In 1973, Winnie et al. introduced the inguinal paravascular three-in-one block, which allegedly provides anesthesia of three nerves--the femoral, lateral cutaneous femoral, and obturator nerves--with a single injection. This concept was undisputed until the success of the obturator nerve block was reassessed by using evidence of adductor weakness rather than cutaneous sensory blockad...

The occipital nerve block is used to diagnose and treat occipital neuralgia. The clinical presentation of occipital neuralgia, the anatomy of the greater occipital nerve, and the technique of the occipital nerve block is described.

BACKGROUND Sciatic nerve block is widely used for anesthesia and analgesia in lower limb surgery, traditional method used for sciatic nerve block is nerve stimulation guidance. Whether the use of ultrasound-guided technology can increases the success rate of sciatic nerve block and provide other benefits are not defined. This meta-analysis was aimed to clarify this issue. METHOD We searched P...

Nerve block is the mainstay of therapy at pain clinics in Japan. The results of nerve blocks, namely the blocking of sensory pain pathways, vicious cycles of pain, sympathetic neural functions, and motor nerves are very useful in treating pain. If the same effects are to be obtained by drug administration, the concomitant use of many drugs with different actions is necessary, but even so, the e...

following our previous investigations on certain new aminoalkyl aryl ethers, which showed promising and outstanding local anaesthetic properties, the local anaesthetic activity and duration of action of a further selection of four novel derivatives of the above-mentioned series, used as hydrochloride salts, have been determined by the ill vivo rat sciatic nerve test. these are: n,n-dimethyl-2-(...

Arthroscopic shoulder surgery has a 45% incidence of severe postoperative pain. Opiates and interscalene nerve blocks have a high incidence of side effects, and intraarticular local anesthetic has been shown to be ineffective when used for postoperative pain relief. The suprascapular nerve supplies 70% of the sensory nerve supply to the shoulder joint, and local anesthetic block of this nerve i...

We studied the effects of serotonin (5-HT) on hippocampal CA1 pyramidal neurons. In current-clamp mode, 5-HT induced a hyperpolarization and reduction of excitability due to the opening of inward rectifier K+ channels, followed by a late depolarization and partial restoration of excitability. These two components could be dissociated, as in the presence of BaCl2 to block K+ channels, 5-HT induc...
