Journal ArticleDOI
Succinylcholine-induced hyperkalemia in acquired pathologic states: etiologic factors and molecular mechanisms.
TL;DR: The nicotinic (neuronal) α7 acetylcholine receptors, recently described to be expressed in muscle also, can be depolarized not only by acetyl choline and succinylcholine but also by choline, persistently, and possibly play a critical role in the hyperkalemic response to succinyl choline in patients with up-regulated AChRs.
Journal ArticleDOI
The efficacy of GlideScope® videolaryngoscopy compared with direct laryngoscopy in children who are difficult to intubate: an analysis from the paediatric difficult intubation registry.

TL;DR: During difficult tracheal intubation in children, direct laryngoscopy is an overly used technique with a low chance of success and GlideScope use was associated with a higher chance ofsuccess with no increased risk of complications.
Journal ArticleDOI

TL;DR: Fiber-optic intubation via supraglottic airway is associated with higher first-attempt success than videolaryngoscopy in infants with difficult airways, and continuous ventilation through the supranational airway during fiber-optIC intubations attempts may lower the incidence of hypoxemia.
Journal ArticleDOI
Long-term effects of botulinum toxin on neuromuscular function.
Christiane G. Frick,Martina Richtsfeld,Nita Sahani,Masao Kaneki,Manfred Blobner,J. A. Jeevendra Martyn +5 more
TL;DR: Botulinum toxin causes dose-dependent long-term neuromuscular changes that are almost exclusively related to muscle atrophy, because the specific tension did not change, and its interactions with different isoforms of receptors having varying sensitivity to atracurium are suggested.
Journal ArticleDOI
Transgenic Alzheimer mice have a larger minimum alveolar anesthetic concentration of isoflurane than their nontransgenic littermates.
TL;DR: The increased MAC value in aged heterozygote APP23 mice seems to be attributable to changes related to Alzheimer's disease.
