Abstract:
Objective:To explore the protective effect of hypothermia plus extracorporeal membrane oxygenation(ECMO)on kidney in brain-dead kidney transplant donors.Methods:From July 2017 to July 2018 at Institute of Transplantation Medicine, Hospital No. 923 of PLA, 29 patients with circulatory dysfunction brain death donors fulfilling the organ donation criteria were randomly divided into sub-hypothermia group according to the treatment of extracorporeal membrane oxygenation(body temperature 34.0~35.0℃, 15 cases)and normal temperature group(36.5~37.5℃, 14 cases). Hemodynamic profiles and renal function changes were compared between two groups during ECMO.And renal complications of two groups were followed up.Results:The hemodynamic parameters of two groups remained stable during ECMO period.Heart rate of 5 MO-organs was lower in hypothermia group than that in normal temperature group( P<0.05). Systolic and diastolic pressures before ECMO 3 h-organ acquisition were higher than normal temperature group( P<0.05). No significant difference existed between PaO 2 and normal temperature groups( P>0.05). Donor serum creatinine(SCr)and blood urea nitrogen(BUN)were lower in hypothermia group than in normal temperature group( P<0.05). The postoperative recipient levels of BUN were lower in mild hypothermia group than those in normothermia group( P<0.05)and no significant difference between SCr and normal temperature groups( P>0.05). The postoperative hospital stay was(16.52±3.59)days in mild hypothermia group. And it was lower than that in normal temperature group( P<0.05). Delayed renal function was lower than normal temperature group(3.45% and 21.43%, P<0.05). Conclusions:Mild hypothermia plus ECMO can reduce hemodynamic fluctuations in circulatory unstable donors after brain death, improve renal function and lower the incidence of delayed functional recovery after renal transplantation.
