BACKGROUND

The recent outbreak of AH1N1 influenza was associated with an increased number of respiratory complications. There were some extremely severe cases of ARDS, in which conventional therapy could not secure adequate gas exchange. These patients fulfilled ECMO criteria, however, due to late referral, were not suitable for transportation. To solve this problem, a portable ECMO system, providing for safe management of these patients, has been introduced in our institution.

CASE REPORT

We reviewed five adult ARDS patients, who were transported by an ambulance for a distance ranging from 2 to 95 km, over 35 to 120 min. In four cases, a veno-venous ECMO system was used, and one patient had an arterio-venous circuit. All circuits were implanted before transportation by a dedicated team from the reference hospital, comprising an anaesthesiologist, a cardiac surgeon and a perfusionist. All transportations were successful and no complications and/or technical problems were observed. During the subsequent ITU treatment, three patients survived and two died (one because of uncontrollable bleeding from the ECMO cannula, and one because of sepsis and multiple organ failure).

CONCLUSION

We conclude that safe use of ECMO during transportation is possible, and does not require very sophisticated and expensive equipment. A standard ambulance is sufficient for the purpose.
