BACKGROUND AND OBJECTIVES The authors describe a new approach for the management of adductor muscle spasm associated with multiple sclerosis and paraplegia. METHODS An obturator nerve block was performed by needle insertion behind the upper end of the adductor longus muscle; the needle was directed laterally, with slight upward and posterior inclination,(More)
A local analgesic block of the posterior tibial nerve, using a new subcalcaneal approach, is described. The point of insertion of the needle is defined in relation to a bony prominence below the medial malleolus, the sustentaculum tali, to which the posterior tibial nerve bears a constant relationship. Twenty patients given a posterior tibial block using(More)
BACKGROUND In this prospective, randomized, double-blind study, we evaluated whether a very low dose of spinal bupivacaine could be sufficient for safe performance of short perianal surgery. METHODS Eighty patients were randomly assigned to receive hyperbaric bupivacaine doses of either 1.5 mg (n = 40) or 6.0 mg (n = 40). RESULTS The lower dose produced(More)
A new approach for the management of frozen shoulder associated with reflex sympathetic dystrophy is presented. A suprascapular nerve block was performed by needle insertion behind the lateral end of the clavicle at its junction with the insertion of the trapezius muscle; the needle was directed downwards and backwards. The suprascapular nerve was(More)
BACKGROUND AND OBJECTIVES Our objective was to evaluate the efficacy of the paravertebral block for inguinal herniorrhaphy by comparison with the well-established field block. METHODS Thirty patients undergoing inguinal herniorrhaphy were randomly divided into two groups. Group A (n = 15) received paravertebral block of the ipsilateral nerve roots of T12,(More)
The cardiovascular effects of ergometrine have been examined using animal models in vivo and in vitro. In rats in vivo the pressor effects of a standard dose of ergometrine were found to be dependent upon the anaesthetic used for the procedure. The pressor action of ergometrine was greater when urethane, an anaesthetic which produces both sympathetic and(More)
BACKGROUND AND OBJECTIVES The stellate ganglion can alleviate phantom pain of the upper extremity, possibly because of the presence in it of enkephalin receptors, as has been suggested by experimental and clinical reports. A case is reported in which fentanyl, instead of local anesthetic, was used for stellate ganglion block. METHODS A 49-year-old man,(More)
