In December 2019, reports of an atypical pneumonia emerged from the city of Wuhan, Hubei province of China. 1 The infectious agent was soon identified as a novel enveloped betacoronavirus. 2,3 Coronaviruses are enveloped non-segmented positive sense RNA viruses belonging to the family Coronaviridae. 4 This newly identified coronavirus, has been named Severe Acute Respiratory Syndrome CoronaVirus 2 (SARS-CoV-2) by the World Health Organization (WHO). This is the third large scale health crises caused by a betacoronavirus. Severe Acute Respiratory Syndrome CoronaVirus (SARS-CoV) and Middle East Respiratory Syndrome CoronaVirus (MERS-CoV) represent the previous health crises. Mortality rate of SARS-CoV and MERS-CoV was 10% and 37%, respectively. SARS-CoV and MERS-CoV infections were reported in 26 and 27 countries, respectively. A total 10,590 cases of infections were caused by both viruses. 5-11 On January 30, WHO declared the novel coronavirus outbreak (2019-nCoV) a public health emergency of
Summary Intra‐operative hypotension is a known predictor of adverse events and poor outcomes following major surgery. Hypotension often occurs on induction of anaesthesia, typically attributed to hypovolaemia and the haemodynamic effects of anaesthetic agents. We assessed the efficacy of fluid optimisation for reducing the incidence of hypotension on induction of anaesthesia. This prospective trial enrolled 283 patients undergoing radical cystectomy and randomly allocated them to goal‐directed fluid therapy (n = 142) or standard fluid therapy (n = 141). Goal‐directed fluid therapy patients received fluid optimisation based on stroke volume response to passive leg raise before induction; those with positive passive leg raise received intravenous crystalloid fluid boluses until stroke volume was optimised. Baseline mean arterial pressure was measured on the morning of surgery and on arriving in the operating theatre. This post‐hoc analysis defined haemodynamic instability as either a > 30% relative drop in mean arterial pressure compared with baseline or absolute mean arterial pressure < 55 mmHg, within 15 min of induction. Forty‐two (30%) goal‐directed fluid therapy patients underwent fluid optimisation after finding an intravascular fluid deficit via passive leg raise testing; 106 (75%) goal‐directed fluid therapy and 112 (79%) standard fluid therapy patients met criteria for haemodynamic instability. There was no significant difference in the incidence of haemodynamic instability between the goal‐directed fluid therapy and standard fluid therapy groups using absolute mean arterial pressure drop below 55 mmHg (p = 0.58) or using pre‐surgical testing or pre‐surgical mean arterial pressure values as baseline (p = 0.21, p = 0.89, respectively); however, the difference in the incidence of haemodynamic instability was significant using the operating theatre baseline mean arterial pressure (p = 0.004). We conclude that fluid optimisation before induction of general anaesthesia did not significantly impact haemodynamic instability.
The association between epilepsy and erectile dysfunction (ED) has often been described but not clearly defined. This is a review of the literature regarding the current theories on the causes of ED in epilepsy, as well as the evaluation and treatment options available.
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.
