EP.- The Spanish Society of Critical Intensive Medicine and Coronary Units (SEMICYUC) has warned that, according to "the information that is currently being studied," flu viruses predominantly circulating in Spain are type A , which increases the possibility of more patients requiring hospitalization and a higher frequency of patients with complicated viral pneumonia.

Both the pandemic virus, A (H1N1) pdm09, such as the epidemic or A (H3N2), belong to Type A and "for previous years' experience, when the circulation of A (A) H1N1) pdm09, there is a greater chance that more cases of patients who have to be hospitalized and a greater frequency of patients with complicated viral pneumonia that require entry to the Intensive Care Units to receive supportive treatment and, in many cases, an artificial respiration, "they have indicated from SEMICYUC.

Although most patients who suffer from flu each winter have mild signs of the disease and heal without problems, a small proportion of them have associated complications. The main one, with a percentage of 90 percent, is respiratory. The pictures go from bronchitis to more or less severe pneumonia.

In addition, a percentage that ranges from 2 to 3 percent of patients admitted to the ICU, showed signs and symptoms compatible with meningitis or viral encephalitis with a serious prognosis, they released group data on Grip A Grave of the SEMICYUC.

The negative impact of influenza virus infection, especially when it is type A (H1N1) pdm09, occurs in decompensating patients with chronic and advanced illnesses. SEMICYUC has insisted on the importance of vaccinating a large part of the population to prevent this type of death, which, although not frequent, is very shocking and make us rethink the need for a vaccination in the whole population independent of age or known risk factors.

In this context, the company reported that it has opened the GETGAG registry on influenza from its Spanish Flu Traffic Group, which is already underway in 2009. It provides relevant information regarding the epidemiology of this disease , as well as to prognostic factors and the impact of the treatment on the most serious populations. The intention is for the ICU to notify the cases of this new flu season.

"In 2009, when the World Health Organization decreed the level of pandemic, SEMICYUC created its work group for the follow-up and study of influenza. Since then, more than 4,000 patients have been registered in the GETGAG database. The contribution of data for more than 184 Spanish UCIs in the base in almost real time, has allowed to make periodic reports and obtain a monitoring of how each winter period is developed in relation to the type of patients and their severity, "the coordinator of this work group of SEMICYUC, doctor Alejandro Rodríguez.


All ICUs at the national level follow specific protocols for the treatment and management of patients admitted for flu complications suggested by the SEMICYUC since 2009, and have the support of the Ministry of Health, Consumer Affairs and Social Welfare.

"Since the emergence of the pandemic in 2009, intensive care services have played a transcendental role in the treatment of severe flu cases. The possibility of providing advanced respiratory support and often using complex extracorporeal oxygenation systems have allowed to rescue a large number of serious patients of an almost safe fatal complication, "said Dr. Rodríguez.

However, two out of ten patients die at the ICU due to flu complications. "One of the possible causes related to this mortality could be in the delay in the diagnosis due to a delayed consultation of the patients", he emphasized the expert.

"According to data that we collect in the Spanish work group on Flu A Grave of the SEMICYUC, the average time that passes between the beginning of the symptoms and the doctor's consultation to the head or emergency is 4 or 5 days, a time Too prolonged because the treatment has the best beneficial effect, "explained Dr. Rodríguez.

The expert has recommended to the public that, during the winter period, a doctor's consultation with influenza symptoms is carried out that lasts more than 24 or 48 hours so that the specialist evaluates, according to the clinical condition of Each patient, the need or not to perform special tests or refer the patient to the hospital.


SEMICYUC underlined that the annual influenza vaccine is "the main and best way to prevent the disease" and has indicated that it has been shown to reduce the risk of influenza, hospitalization and even the risk of death in children ". A child with six months or more "should receive the vaccine every year" and, in parallel, the caregiver of a young child should also be vaccinated.

Also, the company has urged to take daily prevention actions, such as keeping away from ill people; Avoid getting in touch with other people if symptoms have already been detected; Cover your nose and mouth when you cough or sneeze; Wash your hands frequently; Do not touch your eyes, nose or mouth and cleanse and disinfect the most common contact surfaces, especially when someone is sick.

SEMICYUC has reminded that antiviral medications are available to treat influenza in children and adults and can alleviate the severity of the disease and reduce its useful life, as well as preventing serious complications.

"They are more effective when treatment is started within two days after becoming ill, although starting to take it later may still be useful, especially if the patient has a serious problem or is at high risk to present serious complications, "the intensivists pointed out.

"The treatment with antiviral drugs of people who are very ill with flu or who are at high risk of having complications due to influenza can mean the difference between having a milder disease and having a very serious illness that could lead to the disease. hospitalization, "said SEMICYUC, who emphasized that the recommendation to take antivirals is also recommended by the Centers for Disease Control.

At the UCI, the preventive measures with the greatest impact go from the vaccinations of the personnel and the early detection of the most severe patients who will require admission to intensive care units, to measures of isolation and rapid detection of patients. This virus, along with the precocious start of antiviral treatment.
