Despite healthcare improvement, mortality still remains high and few therapies are nowadays available.
Despite this improvement, mortality remains at about 40%, and many survivors have permanent neurologic, cognitive, and neuropsychologic deficits.
This study also found that clinical improvement, mortality, and intracranial hemorrhage were not associated with age or sex in treatments involving alteplase.
Another study from China reported that early treatment with lamivudine led to a greater decrease in HBV DNA level, better clinical improvement and mortality improvement in patients with severe acute hepatitis B [ 10].
Although some randomized controlled trials have reported improvements in mortality, the current overall hospital mortality is about 40-50 % in most series of ARDS patients [ 20, 39].
Hence, apart from studying improvements in mortality levels, future studies must analyze the inequality in mortality to assess the performance of societies on length of life.
"There is a substantial risk, if you want to look at it that way, that we will see substantial improvements in mortality among the old," said Chris Carroll, an economics professor at the Johns Hopkins University.
There are several small and large animal models that demonstrate improvements in mortality with fluid resuscitation.
The observed improvements in mortality and gas exchange raise the question of the mechanisms involved.
