[Status asthmaticus. Role of extracorporeal lung assist procedures].

The successful application of a pumpless extracorporeal lung assist procedure ("interventional lung assist, iLA) in three cases of severe refractory status asthmaticus, which could not be solved with conventional pharmacological and respiratory therapy is reported. After an individual risk-benefit analysis such a therapy can be used to reduce lung injury due to invasive mechanical ventilation. Because of the complexity of this therapy it should only be applied in special medical centers with sufficient experience in dealing with extracorporeal lung assist procedures.
