| 1 | Non-invasive versus invasive mechanical ventilation for respiratory failure in severe acute respiratory syndrome显示文摘Background Severe acute respiratory syndrome is frequently complicated by respiratory failure requiringventilatory support.We aimed to compare the efficacy of non-invasive ventilation against invasive mechanicalventilation treating respiratory failure in this disease.Methods Retrospective analysis was conducted on all respiratory failure patients identified from the HongKong Hospital Authority Severe Acute Respiratory Syndrome Database.Intubation rate, mortality and secondaryoutcome of a hospital utilizing non-invasive ventilation under standard infection control conditions ( NIVHospital) were compared against13 hospitals using solely invasive ventilation (IMVHospitals).Multiple logisticregression analyses with adjustments for confounding variables were performed to test for association betweenoutcomes and hospital groups.Results Both hospital groups had comparable demographics and clinical profiles, but NIV Hospital (42patients) had higher lactate dehydrogenase ratio and worse radiographic score on admission and ribavirin-corticosteroid commencement.Compared to IMV Hospitals (451 patients), NIV Hospital had lower adjustedodds ratios for intubation (0.36, 95% CI 0.164 -0.791,P=0.011) and death (0.235, 95% CI 0.077 -0.716,P=0.011), and improved earlier after pulsed steroid rescue.There were no instances of transmission ofsevere acute respiratory syndrome among health care workers due to the use of non-invasive ventilation.Conclusion Compared to invasive mechanical ventilation, non-invasive ventilation as initial ventilatory supportfor acute respiratory failure in the presence of severe acute respiratory syndrome appeared to be associated withreduced intubation need and mortality. | Loretta YC Yam Alfred YF Chan Thomas MT Cheung Eva LH Tsui Jane CK Chan Vivian CW Wong | 2005 | Chinese Medical Journal2005，，17： | 3 |
