Via BBC News Brasil: Exclusive: 80% of covid-19 intubated died in Brazil in 2020. Excerpt from the Google translation:
For a serious covid-19 patient with lungs that have lost the ability to oxygenate blood, intubation can relieve pain and be the only hope for survival.
But in Brazil, the high percentage of deaths among those infected who need mechanical ventilation is frightening: the average was around 80% from February to December 2020, according to data from an unprecedented survey obtained exclusively by BBC News Brasil.
In other words, 8 out of 10 patients intubated during the first year of the pandemic died. Mortality remained the same in the first and second semesters, which shows that Brazil did not know how to effectively apply the lessons learned on treating patients with covid-19.
For comparison, the world average is around 50% mortality. And, according to the researchers involved in this study, preliminary data from 2021 show that the Brazilian mortality rate is expected to worsen.
