Keywords: procedural sedation; definition; consensus EN procedural sedation definition consensus 598 601 4 04/05/21 20210501 NES 210501 Surprisingly, there is no generally accepted definition for the practice of procedural sedation. Sedation states within the purview of the above definition include minimal sedation, moderate sedation, dissociative sedation and deep sedation. Similarly, whereas awareness/recall should not occur during general anaesthesia, for procedural sedation it is, by definition, very likely with minimal or moderate sedation and possible with deep sedation.

Are tracheal intubation and extubation aerosol-generating procedures? Keywords: airborne; contact; coronavirus; COVID-19; droplet; personal protective equipment; intubation; extubation EN airborne contact coronavirus COVID-19 droplet personal protective equipment intubation extubation 151 155 5 01/15/21 20210201 NES 210201 "a wise man proportions his belief to the evidence" David Hume (Scottish Enlightenment Philosopher, 1711-1776) The COVID-19 pandemic has significantly impacted peri-operative care due to staff redeployment and a reduction in elective surgery secondary to depletion of resources and a requirement for increased infection control procedures in order to protect healthcare staff. As well as patients with severe COVID-19 infection who require tracheal intubation, patients may be relatively asymptomatic and present for surgery. If sicker patients pose a higher transmission risk, is a healthcare worker performing tracheal intubation contracting COVID-19 highly likely?. [Extracted from the article]

Keywords: anaesthesia induction; fluid replacement; hypotension; hypovolaemia; propofol administration EN anaesthesia induction fluid replacement hypotension hypovolaemia propofol administration 15 18 4 12/11/20 20210101 NES 210101 Avoiding post-induction and intra-operative hypotension remains an everyday challenge in anaesthesia. Pre-operative hypovolaemia is traditionally acknowledged as a risk factor for post-induction hypotension but does the corollary hold true, that is, will euvolaemia prevent post-induction hypotension? As all patients were to undergo a similar major operation starting at the same time of the day, they had relatively uniform fasting times and patients from both groups had similar induction drug doses. Given the type of patients in this study, it is very likely that propofol doses have contributed to the hypotension observed and swamped the potential, if any, benefits of fluid optimisation.
