Patients requiring neuromuscular block for anaesthesia have a higher risk of adverse postoperative outcomes. The choice of reversal drug and its corresponding dose is critical for improving clinical outcomes. ⋯ New data from a recent study in the British Journal of Anaesthesia indicate cost advantages for sugammadex in low-risk and ambulatory patients, but for neostigmine in high-risk patients. These findings highlight the need to take local and temporal factors into consideration in addition to clinical effectiveness when performing cost analyses for administrative decision-making.

Depth of anaesthesia monitoring: time to reject the index?
Depth of anaesthesia monitors can fail to detect consciousness under anaesthesia, primarily because they rely on the frontal EEG, which does not arise from a neural correlate of consciousness. A study published in a previous issue of the British Journal of Anaesthesia showed that indices produced by the different commercial monitors can give highly discordant results when analysing changes in the frontal EEG. Anaesthetists could benefit from routinely assessing the raw EEG and its spectrogram, rather than relying solely on an index produced by a depth of anaesthesia monitor.

The molecular mechanisms of susceptibility to malignant hyperthermia are complex. The malignant hyperthermia susceptibility phenotype should be reserved for patients who have a personal or family history consistent with malignant hyperthermia under anaesthesia and are subsequently demonstrated through diagnostic testing to be at risk.
