Mortality among patients admitted to intensive care units (ICUs) with COVID-19 is unclear due to variable follow-up periods. Few nationwide data are available to compare risk factors, treatment and outcomes of COVID-19 patients after ICU admission. ⋯ Thirty-day mortality rate in COVID-19 patients admitted to Swedish ICUs is generally lower than previously reported despite a severe degree of hypoxaemia on admission. Mortality was driven by age, baseline disease severity, the presence and degree of organ failure, rather than pre-existing comorbidities.

Spinal anaesthesia-induced hypotension is frequently reported in patients undergoing caesarean section. Mechanistically, sympathetic blockade reduces the systemic vascular resistance and the left ventricular preload, causing hypotension, which is augmented by aortocaval compression. The corrected blood flow time (FTc) is affected by the preload and is inversely related to the afterload. ⋯ Preanaesthetic carotid artery FTc was a reliable indicator of postspinal hypotension in parturients. Considering the grey zone, Wodey's formula is better than Bazett's formula.

In light of the coronavirus disease-2019 (COVID-19) pandemic, how resources are managed and the critically ill are allocated must be reviewed. Although ethical recommendations have been published, strategies for dealing with overcapacity of critical care resources have so far not been addressed. ⋯ Experts in critical care support the allocation of resources from centres with overcapacity. The results indicate the need for centrally administered allocation mechanisms that are not based on ethically disputable triage systems. It seems, therefore, that there is wide acceptance and solidarity among the European anaesthesiological community that local medical and human pressure should be relieved during a pandemic by implementing national and international re-allocation strategies among healthcare providers and healthcare systems.
