This investigation was a retrospective study of all lung transplant recipients treated with HBO therapy at the Alfred Hospital between March 1990 and August 2005.
In this study we describe 9 patients (1.7%) from a total of 544 overall lung transplants performed over the period. Indications included: sternal osteomyelitis (n = 4); refractory cellulitis (n = 2); refractory septic arthritis (n = 1); ischemic toes (n = 1); and cerebral arterial gas embolism (n = 1). The patients received 1 to 25 HBO treatments at 100%Fio2 and 100 to 180 kPa for 100 minutes per treatment. The treatment was generally well tolerated, although 2 patients ceased therapy prematurely due to a seizure and ear barotrauma (n = 1 each). Five patients had complete resolution of these life-threatening complications. Long-term survival and graft function were excellent, although graft function temporarily fell.
HBO is a safe therapy for traditional HBO indications after LTx and appears useful, particularly in the management of infectious complications, whereas other therapies have failed or are contraindicated.
