Abstract

Background
The double-lumen cannula (DLC) has begun to be used worldwide for venovenous (VV) extracorporeal membrane oxygenation (ECMO). We aimed to examine whether the DLC could be an effective tool in the treatment of pediatric respiratory failure in Korea.
Methods
We reviewed the records of patients weighing under 15 kg who underwent ECMO due to respiratory failure between January 2017 and December 2018. Outcomes of ECMO using a DLC and conventional ECMO using central method or 2 peripheral cannulas were compared.
Results
Twelve patients were treated with ECMO for respiratory failure. Among them, a DLC was used in 5 patients, the median age of whom was 3.8 months (interquartile range, 0.1–49.7 months). In these patients, the median values of pH, partial pressure of carbon dioxide, and partial pressure of oxygen were 7.09, 74 mm Hg, and 37 mm Hg before ECMO and corrected to 7.31, 44 mm Hg, and 85 mm Hg, respectively, after ECMO cannulation. Median blood flow rate in the patients treated with ECMO using a DLC was slightly higher than that in the conventional ECMO group, but this difference was not statistically significant (86.1 mL/kg/min and 74.3 mL/kg/min, respectively; p=1.00). One patient from the DLC group and 3 patients from the conventional group were weaned off ECMO.
Conclusion
VV ECMO using a DLC provided adequate oxygenation, ventilation, and blood flow rate in Korean pediatric patients with respiratory failure. Further prospective and randomized studies are warranted.
