Clinical TrialNerve blocks with 5% butamben suspension for the treatment of chronic pain syndromes.
Butamben is a non-water-soluble local anesthetic that can be prepared as an aqueous suspension for nerve blocks. This report describes the use of 5% butamben suspension for the treatment of chronic pain of cancer and noncancer origin. ⋯ When used as described in this report, 5% butamben suspension appears to be effective for treatment of chronic pain of both cancer and noncancer origin and has a low incidence of adverse sequelae.

Randomized Controlled Trial Clinical TrialDifferential effect on vasodilatation and pain after intradermal capsaicin in humans during decay of intravenous regional anesthesia with mepivacaine.
When given intracutaneously, capsaicin can cause burning pain by central propagation in thin afferents, as well as neurogenic vasodilatation, reflecting antidromic conduction in the same fibers. We wanted to test the hypothesis that an intravenous regional block (IVRA) inhibits these two phenomena to a similar degree. ⋯ Mepivacaine, given as an IVRA, had no effect on the post-IVRA sensory function of thin afferents but differentially decreased the spread of the capsaicin-induced flare.

Case ReportsUnusually prolonged duration of spinal anesthesia following 2% mepivacaine.
Spinal mepivacaine has been reported as a reliable anesthetic for ambulatory anesthesia. Its pharmacologic properties are midway between those of bupivacaine and lidocaine, and it can be used in intermediate duration ambulatory surgical procedures. ⋯ Clonidine can increase the duration of spinal anesthetics. Even though this well-known effect has been considered mostly beneficial, it can be an adverse effect when spinal ambulatory anesthesia is given to patients receiving clonidine TTS or clonidine in other forms for long-term treatment of hypertension or other diseases.
