Kids Hospitalized for Flu Need Antiviral Meds Right Away: Study
Survival odds increase with early administration of drugs such as oseltamivir, researchers say
The drug's side effects also should not be an issue. The main side effects are nausea and vomiting, which are much more common in children but occur in less than 10 percent of patients.
The explanation might be that smaller hospitals that treat fewer cases of the flu do not have the same level of experience and sense of urgency as hospitals that regularly deal with flu outbreaks, Ramilo said.
"If you work in a big teaching hospital, then you see these cases more often," he said. "The [doctors] think about it right away."
Some doctors also may not suspect flu when they start treating a very sick child. "Many clinicians may not initially consider influenza as a possible cause of respiratory illness or pneumonia, especially when it occurs outside of the peak of the influenza season," Louie said.
Another problem could be that intravenous forms of the antiviral medications currently are not available, Ramilo said. Kids have to take them by mouth, and very sick kids often are administered the medication via a tube snaked through their nose and down their throat.
Although this study lends hope for treating critically ill children, Ramilo and Whitley said flu shots remain the first and best line of defense against the flu.
"Children need to be immunized just like adults need to be immunized," Whitley said. "It's still the best approach we have to prevent influenza."
