Masseteric muscle spasm as a normal response to suxamethonium.
The myotonic response of the masseter muscles following various doses of suxamethonium was measured using a unique myotonometer in 50 apparently healthy patients, the majority of whom showed a myotonic response which lasted less than 100 s. A maximum increase in masseter tone was found to be greater than 1 kg in five patients, and 12 patients developed a maximum tone of greater than 500 g. An i...
متن کاملAnaesthetists' nightmare: masseter spasm after induction in an undiagnosed case of myotonia congenita.
We report an undiagnosed case of myotonia congenita in a 24-year-old previously healthy primigravida, who developed life threatening masseter spasm following a standard dose of intravenous suxamethonium for induction of anaesthesia. Neither the patient nor the anaesthetist was aware of the diagnosis before this potentially lethal complication occurred.
متن کاملImpossible mask ventilation after an unusually low dose fentanyl-induced muscle rigidity in a patient with essential tremor: a case report and review of the literature.
Although opioid-induced muscle rigidity occurs more commonly with large doses and rapid administration of the drugs, there is a number of cases reported, where muscle rigidity was experienced with lower doses of opioids. We present and discuss a case of muscle rigidity induced by an unusually low dose of fentanyl as primary agent during induction of anesthesia. A 79 year old male patient, sched...

OBJECTIVES To report a case and discuss the mechanism of hemimasticatory spasm. DESIGN Case report. PATIENT A 37-year-old woman had a 3-year history of involuntary spasms of the right masseter muscle in association with localized scleroderma and facial hemiatrophy.

متن کاملOnset of neuromuscular block at the masseter and adductor pollicis muscles following rocuronium or succinylcholine.
PURPOSE To compare the onset time of two different rocuronium doses (0.6 and 0.9 mg x kg(-1)) and succinylcholine (1.5 mg x kg(-1), preceeded by 0.06 mg x kg(-1) rocuronium) at the masseter and the adductor pollicis muscle. METHODS In a randomized study, 60 ASA I or II adult women, 18-65 yr of age, were anesthetized with propofol and fentanyl and nitrous oxide in oxygen. Neuromuscular monitor...
