Recently, 6 percent of COVID-19 patients required prolonged mechanical ventilation due to severe respiratory failure. Early tracheostomy prevents the risk of postintubation upper airway stenosis. ⋯ Authors present their recommendations based on international experiences. Orv Hetil. 2020; 161(19): 767-770.

Introduction: At the end of March, 2020, rapid tests detecting the presence of antiviral IgM and IgG antibodies against SARS-CoV-2 virus were introduced in Hungary for the identification of SARS-CoV-2 infection (COVID-19 disease). Aim: We evaluated two rapid tests (Anhui and Clungene) in comparison with those of real-time PCR tests considered as the gold standard in the detection of infection. Method: Between 16, March and 14, April, 2020, we performed rapid IgM and IgG detecting tests without PCR; PCR without rapid tests; and PCR WITH rapid tests in 4140, 3210 and 1654 patients, respectively. (Out of these 1654 patients, Anhui and Clungene tests were used for testing in 625 and 1029 patients, respectively.) Patients were considered as positive in PCR and rapid tests when PCR positivity and IgM or IgG positivity occurred at any time, respectively. (Note: Clungene test is also marketed as 'Lungene'.) Results: The prevalence of PCR positivity in 4864 patients tested with PCR was 6.3%. ⋯ Conclusion: The low positive predictive values indicate that Anhui and Clungene rapid tests detecting the presence of anti-IgM and anti-IgG against SARS-CoV-2 virus infection are not suitable for screening SARS-CoV-2 vírus infection in the general population. These results strongly support that Anhui and Clungene rapid tests detecting IgM and IgG antibodies against SARS-CoV-2 virus should not be used in the differential diagnosis of infection.

Due to the coronavirus epidemic, healthcare systems face growing challenges all around the world nowadays. These challenges are the most critical in the field of intensive treatment and anesthesiology. ⋯ The aim of the present review is to summarize the most important related knowledge available from previous experiences.

In December 2019, a cluster of pneumonia cases of unknown origin occured in Wuhan, China. The identified infective agent is a novel corona virus called “severe acute respiratory syndrome coronavirus 2” (SARS-CoV-2) and the respiratory disease caused by this agent aquired the name “coronavirus disease 2019” (COVID-19). In March 2020, the World Health Organization (WHO) declared the novel coronavirus outbreak a pandemic. ⋯ The chances of the critically ill patients could be improved solely by a high-quality and careful critical care. It is prudent to meet the experiences of colleagues working hard with these patients in the already heavily infected countries. Orv Hetil. 2020; 161(17): 667–671.

The coronavirus pandemic is a serious challenge for healthcare workers worldwide. The virus is spread through the air by droplets of moisture when people cough or sneeze and it has a very high virulence. Procedures generating airway aerosols are dangerous for every participant of patient care. ⋯ Resuscitation is an aerosol-generating process and thus carries the risk of contamination. The goal of this article is to give a practice-based overview of the specialities of cardiopulmonary resuscitation in coronavirus-infected patients. Orv Hetil. 2020. 161(17): 710–712.
