Survival from a malignant hyperthermia (MH) crisis is highly dependent on early recognition and prompt action. MH crises are very rare and an increasing use of total i.v. anaesthesia is likely to make it even rarer, leading to the potential risk of reduced awareness of MH. In addition, dantrolene, the cornerstone of successful MH treatment, is unavailable in large areas around the world thereby...
A double-blind study was carried out on 20 children with spasticity secondary to cerebral palsy, in order to compare the effects of dantrolene sodium suspension and a placebo. The drug was found to be physiologically active in reducing the force of muscle contraction, but objective functional improvement, as measured by multiple performance tests, was irregular and probably not significant.
An episode of malignant hyperthermia occurring in a two-year-old child undergoing cardiac surgery is reported. The coincidental usage of hypothermic cardiopulmonary bypass obscured the classical presenting signs and symptoms of the syndrome. Once the clinical diagnosis was confirmed, rapid reversal was achieved with the administration of dantrolene sodium.
We have studied the ability of the calcium channel antagonist diltiazem to inhibit and reverse the porcine malignant hyperpyrexia (MH) syndrome. Pretreatment with diltiazem modified an MH response. Treatment with diltiazem was partially effective against a mild (or early) MH response. Diltiazem should not be considered to be an effective therapeutic agent for MH and should not displace the use ...
We tested the hypothesis that stimulation of metabotropic glutamate receptors (mGluRs) increases nitric oxide (NO) production in the hippocampus in vivo. Microdialysis probes were placed bilaterally into the CA3 region of the hippocampus of adult Sprague-Dawley rats under pentobarbital anesthesia. Probes were perfused for 5 h with artificial cerebrospinal fluid (CSF) containing 3 microM [14C]-L...
BACKGROUND AND PURPOSE New therapies for cerebral vasospasm after subarachnoid hemorrhage are needed because of its high morbidity and mortality rates. We investigated the feasibility and safety of a single dose of intravenous dantrolene and its effect on transcranial Doppler in cerebral vasospasm after subarachnoid hemorrhage. METHODS In a prospective, open-label, single-dose ascending safet...
The effects of dantrolene sodium and diazepam were compared in a double crossover study of 42 patients with spasticity due to stable multiple sclerosis. Both drugs reduced the findings of spasticity, clonus, and hyperreflexia, and the complaints of muscle stiffness and cramping. Each drug had different side effects which suggest indications and contraindications for its use in spastic patients.
Suxamethonium induced a contracture in caffeine pretreated human muscle in vitro. The contracture was significantly greater (P less than 0.001) with MHS muscle compared with muscle from normal subjects. This reaction is now used as an additional screening test for the MHS phenotype. The contracture was prevented by pretreatment with dantrolene.
