Highlights
Evidence suggests that the rate of thrombotic events such as pulmonary embolism is high in patients with COVID-19.
Patients undergoing CT pulmonary angiography in the emergency department on a triage pathway at our institution have a low detection rate of pulmonary embolus.
The frequency of thrombotic complications may be higher later on in the disease.
and produce excellent sedative effects [3]. They exert a central sympatholytic action, improving haemodynamic stability in response to tracheal intubation and surgical stress and reduce general anaesthetic and opioid requirements. Furthermore, they may be beneficial in the prophylaxis and treatment of peri-operative myocardial ischaemia [4]. The role of magnesium in attenuating the stress response is also worth considering. Magnesium plays an important role in many physiological processes such as regulation of blood catecholamine concentrations, particularly adrenaline and noradrenaline [5].
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
