Incidence of acute kidney injury within 3 days after lung transplantation, related risk factors and its influences on short-term prognosis / 中华器官移植杂志

ABSTRACT

Objective:To explore the incidence and relevant risk factors of acute kidney injury (AKI)after lung transplantation(LT).Methods:Retrospective analysis was performed for clinical data of 70 recipients of LT at China-Japan Friendship Hospital.Results:Among them, 61.4 % developed AKI within 3 days post-LT. As compared with non-AKI and AKI 1 groups, AKI 2~3 group had more plasma transfusion(median 0, 0, 200 ml, P=0.027) and more cardiovascular events during operation(0, 0, 14.3 %, P=0.023). As compared with non-AKI group, AKI 1 and 2~3 groups had lower postoperative hemoglobin in the first day(median 119, 106, 104 g/L, P=0.032). The duration of invasive mechanical ventilation was longer in AKI 2~3 group(median 56 h)than non-AKI group (median 49 h, P=0.034). The 3-month all-cause mortality post-LT was higher in AKI 2~3 (24.1 %)and AKI 1 recipients(21.4 %)than that in non-AKI counterparts(0)( P=0.034, P=0.007). Conclusions:Recipients with more blood transfusion and cardiovascular events during operation and those with more severe anemia in the first day post-LT might be at higher risks for postoperative AKI. Postoperative AKI prolongs the duration of invasive mechanical ventilation and increases 3-month all-cause mortality post-LT.
