OBJECTIVE: To describe clinical features, treatment, complications, and outcomes in cases of acute respiratory distress syndrome (ARDS) caused by H1N1 virus infection treated in an anesthesia department's recovery unit.
MATERIALS AND METHODS: Patients were those admitted to our recovery unit with H1N1 virus infection confirmed by reverse transcription polymerase chain reaction, nasopharyngeal swabs, and/or bronchial aspirates.
RESULTS: From August to December 2009, we admitted 8 patients (mean age, 43 [range 24-46] years) to the recovery unit. Six were men, three were of Roma origin, and 50% had concomitant diseases. Mean (SD) time from symptom onset to admittance to the recovery unit was 3.25 (1.6) days. Four had received broad-spectrum antibiotics during the last month. Six had primary viral pneumonia, 1 had secondary bacterial pneumonia and 1 had exacerbated chronic obstructive pulmonary disease. Three had bacterial coinfection, and 4 developed multiple organ dysfunction syndrome and ARDS, requiring mechanical ventilation (5.75 [3.10] days) and vasopressors (4.25 [3.40] days). The mean ratio of PaO2 to the inspired oxygen fraction at admittance was 93.8 (31.0) and the mean positive end-expiratory pressure applied was 14.5 (4.2) cm H2O. Oseltamivir was administered (150 mg/12 h) with a mean delay of 3.88 (1.64) days. Additional inhaled zanamivir was administered on day 7 to a patient with a positive viral culture. Antibiotics were prescribed following the guidelines of the American Thoracic Society and Infectious Diseases Society of America for community-acquired pneumonia (50% of the cases) and healthcare-associated pneumonia (50%). Seven subjects received 1 mg x kg(-1) x day(-1) of methylprednisolone. Patients with mechanical ventilation required continuous insulin infusion (maximum daily dosage, 87 [50.3] IU) to maintain blood glucose levels between 80 and 150 mg x dL(-1). Patients under mechanical ventilation achieved a negative net fluid balance. All patients survived and were discharged from the recovery unit in 7.38 (4.83) days (range, 2-16 days) and subsequently discharged home in 13.25 (7.74) days (range, 6-27 days). All were alive 60 days after discharge.
CONCLUSION: In this series of critically ill patients with H1N1 virus infection that was initially life-threatening, all responded favorably to conventional treatment and could be discharged.
