Although guidelines for difficult airway management have been published, the extent to which consultant anesthesiologists follow these guidelines has not been determined. The purpose of this study is to observe how consultant anesthesiologists manage a "cannot intubate, cannot ventilate" (CICV) scenario in a high-fidelity simulator and to evaluate whether a simulation teaching session improves their adherence to the American Society of Anesthesiologists (ASA) difficult airway algorithm. ⋯ No substantial changes in airway management in a CICV scenario were observed after an intense one-hour personalized video-assisted airway-focused simulation debriefing session with an expert. It appears that multiple factors other than airway algorithms come into play in emergency airway decision-making processes, including one's personal clinical experience with the many available airway devices.

Case Reports
A report of fulminant malignant hyperthermia in a patient with a novel mutation of the CACNA1S gene.
To report the identification of a novel mutation in the CACNA1S gene that encodes the alpha-1-subunit (Cav1.1) of the voltage-gated skeletal muscle L-type calcium channel in a patient with malignant hyperthermia. ⋯ The homozygous p.Arg1086Ser mutation of CACNA1S, the gene that encodes the alpha-1-subunit of the voltage-gated skeletal muscle L-type calcium channel, is a novel mutation associated with malignant hyperthermia.

Although intensive care unit (ICU) acquired sodium disturbances are common in critically ill patients, few studies have examined sodium disturbances in patients following cardiac surgery. The objective of this study was to describe the epidemiology of ICU-acquired hyponatremia and hypernatremia in patients following cardiac surgery. ⋯ ICU-acquired hyponatremia and hypernatremia are common complications in critically ill patients following cardiac surgery. They are associated with patient demographic and clinical characteristics and an increased risk of hospital mortality.

A case of difficult intubation in a patient with cervical spinal cord injury with diffuse idiopathic skeletal hyperostosis (DISH) is described. The trachea could not be intubated with a videolaryngoscope, and successful intubation was achieved with a laryngeal mask airway device (LMAD) and a fibreoptic bronchoscope (FOB). ⋯ Although often considered to be a benign entity, DISH can predispose patients to catastrophic cervical injury and difficult airway management. Careful review of plain radiographs in the spinal cord injury patient may assist with appropriate selection of airway interventions. The videolaryngoscope is useful for difficult airways, but its effectiveness may be compromised with an anteriorly displaced airway in combination with restricted cervical movement and limited oropharyngeal airspace.

Pregabalin exhibits potent anticonvulsant, analgesic, and anxiolytic activity in animal models. However, few studies have evaluated pregabalin's potential peripheral effects on neuropathic pain. The aim of this study was to evaluate the peripheral analgesic effects of pregabalin in a rat model of neuropathic pain. ⋯ Peripherally administered pregabalin attenuates mechanical, cold, and heat allodynia in a rat model of neuropathic pain.
