Abstract

Historically, patients on extracorporeal membrane oxygenation (ECMO) for acute respiratory distress syndrome have received ventilatory "lung rest" with conventional or high-frequency oscillating ventilators. We present a series of adults treated with high-frequency percussive ventilation (HFPV) to enhance recovery and recruitment during ECMO. Adult respiratory patients, treated between January 2009 and December 2012 were cared for with a combination of standard ECMO practices and a protocol of recruitment strategies, including HFPV. Data are reported as mean ± standard error of the mean, percentage, or median. Comparisons are made by χ for categorical variables and by t-test and Mann-Whitney test for continuous variables. Significance is noted at the 95% confidence level (p < 0.05). There were 39 HFPV patients. They were 39.9 ± 2.2 years of age and had 3.0 ± 0.37 days of mechanical ventilation before the initiation of ECMO. Their pre-ECMO PaO2 to FiO2 ratio (PF ratio) was 52.3 ± 3.0 and their pCO2 was 50.22 ± 2.4. HFPV patients required a mean of 143.1 ± 17.6 hours and a median of 106 hours (range 45.75-350.25) of ECMO support and had a 62% survival to discharge. The post-ECMO PF ratio in the HFPV cohort was 301.8 ± 16.7. A protocolized practice of active recruitment that includes HFPV is associated with reduced duration of ECMO support in adults with respiratory failure.
