Sumario: | This study describes the blood gases features and short-term outcomes with noninvasive positive pressure ventilation (NPPV) treatment in the management of acute respiratory failure (ARF) during a severe acute respiratory syndrome (SARS) epidemic. Between April 22 and May 1, 2003, 120 patients meeting clinical criteria for SARS were admitted to a hospital for infectious diseases in Beijing, China. At 6 weeks after onset, 25% of patients (30/120) had experienced ARF. Of interest, 16 of these patients (53%) exhibited hypercapnia (PaCO(2)> 45 mm Hg), and 10 hypercapnic events occurred within 1 week of admission. The occurence of hypencapnia or CO(2)retention and was accompanied by myalgias. NPPV was instituted in 28 patients; one was intolerant of NPPV. In the remaining 27 patients, NPPV was initiated 1.2 ± 1.6 days after ARF onset. An hour of NPPV therapy led to significant increases in PaO(2)and PaO(2)/FiO(2)and a decrease in respiratory rate (p< 0.01). Endotracheal intubation was required in one third of the patients (9 of 27) who initially had a favorable response to NPPV. Remarkable pulmonary barotrauma was noticed in 7 of all 120 patients (5.8%) and in 6 of those (22%) on NPPV. The overall fatality rate at 13 weeks was 6.7% (8/120); it was higher (26.7%) in those needing NPPV. No caregiver contracted SARS. We conclude that NPPV is a feasible and appropriate treatment for ARF occurring as a result of a SARS infection. |
