We have previously shown that a delayed graft function (DGF) longer than 6 days was a crucial threshold for long-term graft outcome. The aim of this study was to analyze the correlation of DGF >or=6 days with brain-dead donor variables, including those related to resuscitation, in a population of 262 consecutive brain-dead donors from 1990 to 2003.
We used a marginal logistic model in which DGF was considered as a binary variable with a cutoff of 6 days.
Monovariate analysis of donor parameters showed that male, age above 35 years, primary history of hypertension, hydroxyethyl starch (HES) fluid greater than 1500 mL or epinephrine infusion during resuscitation were risk factors for prolonged DGF. The multivariate logistic regression model showed that epinephrine use during donor resuscitation (P<0.001, odds ratio [OR]=4.35), cold ischemia time (CIT) >or=16 hr (P=0.01, OR=2.16), and recipient age >55 years (P=0.003, OR=2.75), were associated with a risk of prolonged DGF. A long stay (>40 hr) in intensive care and a large volume of colloids (>1250 mL, except HES) correlated with a lower risk of DGF.
Our study shows an impact for only a limited number of brain dead donor resuscitation parameters on DGF duration. We also show that CIT has a much lower threshold (<16 hr) for DGF risk than previously described. Importantly, we show that recipient age is clearly a major independent risk factor for prolonged DGF, whereas donor age seems to act mostly as a dependent risk factor.
我们之前已经表明,移植肾功能延迟(DGF)超过6天是长期移植结果的关键阈值。本研究的目的是分析在1990年至2003年连续262例脑死亡供体人群中,DGF≥6天与脑死亡供体变量(包括与复苏相关的变量)之间的相关性。
我们使用了一种边际逻辑模型,其中DGF被视为一个二元变量,截断值为6天。
供体参数的单变量分析显示,男性、年龄超过35岁、高血压病史、复苏期间羟乙基淀粉(HES)液体量大于1500 mL或肾上腺素输注是DGF延长的危险因素。多变量逻辑回归模型显示,供体复苏期间使用肾上腺素(P<0.001,比值比[OR]=4.35)、冷缺血时间(CIT)≥16小时(P=0.01,OR=2.16)和受体年龄>55岁(P=0.003,OR=2.75)与DGF延长的风险相关。在重症监护病房长时间停留(>40小时)和大量胶体(>1250 mL,不包括HES)与较低的DGF风险相关。
我们的研究表明,只有有限数量的脑死亡供体复苏参数对DGF持续时间有影响。我们还表明,CIT对DGF风险的阈值(<16小时)比之前描述的要低得多。重要的是,我们表明受体年龄显然是DGF延长的主要独立危险因素,而供体年龄似乎主要作为一个依赖危险因素起作用。
