Extra vascular lung water but not lung ultrasound predicts grade 3 pulmonary graft dysfunction and utilization of rescue therapies for severe hypoxemia after lung transplantation.

Results 36 patients were included. Among them, 13 (36 %) had grade 3 PGD. EVLWi was significantly higher in the grade 3 PGD group at ICU admission, day one and at day 2. A cut-off value of 14 ml/kg of EVLWi at admission predicts the progression to grade 3 PGD with a sensitivity of 82% and a specificity of 77% and was significantly associated with the need for rescue therapy for severe hypoxemia. Less than a half of patients had all their LUS windows available. LUS scores did not discriminate patients with grade 3 PGD from the others.
