Use of high flow nasal cannula oxygen (HFNC) is increasingly popular in adult ICUs for patients with acute hypoxemic respiratory failure. This is the result of the successful long-term use of HFNC in the neonatal field and recent clinical data in adults indicating beneficial effects of HFNC over conventional facemask oxygen therapy. HFNC rapidly alleviates symptoms of respiratory distress and improves oxygenation by several mechanisms, including deadspace washout, reduction in oxygen dilution and in inspiratory nasopharyngeal resistance, a moderate positive airway pressure effect that may generate alveolar recruitment and an overall greater tolerance and comfort with the interface and the heated and humidified inspired gases. ⋯ HFNC may also alleviate respiratory distress in patients at a palliative stage. Although observational studies suggest that HFNC might reduce the need for intubation in acute hypoxemic respiratory failure; such a reduction has not yet been demonstrated. Beyond this potential additional effect on outcome, the evidence already published argues in favor of the large use of HFNC as first line therapy for acute respiratory failure.

Little is known about current use of neuromuscular blocking agents by Italian anesthetists. This paper reports the results of a survey conducted to obtain information about current management of neuromuscular block in Italy. ⋯ Clinical signs are used by most of the Italian anesthetists to assess the recovery from neuromuscular blockade. There is poor awareness about their inability to indicate even a significant degree of residual neuromuscular block. A more extensive use of quantitative instrumental monitoring is required for the more rational use of neuromuscular blocking agents.

Pain-related middle-latency somatosensory evoked potentials in the prognosis of post anoxic coma: a preliminary report.
Regarding hypoxic-ischemic encephalopathy, while the bilateral absence of N20/P25 somatosensory evoked potentials (SEPs) is considered to be the best indicator of adverse outcomes, the presence of middle latency evoked potentials (MLCEPs) is associated with a favourable neurological prognosis. The main aim of the present study was to investigate whether painful electrical stimulation might be considered a provocative test in producing MLCEPs and predictor of patient's outcomes after cardiac arrest. ⋯ These preliminary data suggest that MLCEPs elicited by painful electrical stimulation seem to be a sensitive method to predict the neurological outcome of patients in the acute phase of coma. Blood pressure response might be a prognostic physiological measure of survival in the vegetative state in patients without N20/P25 SEPs.
