Analysis of risk factors of acute renal failure after surgery for simple abdominal trauma / 中华创伤杂志

ABSTRACT

Objective To investigate the risk factors associated with acute renal failure (ARF)after surgery in patients with simple abdominal trauma. Methods A retrospective case-control study was carried out in patients with simple abdominal trauma after surgery from January 2003 through May 2008 in our hospital. Twenty patients with ARF were set as study group and 68 patients without ARF as control group. Clinical data including age, gender, injury type, number of injured organs, blood transfusion volume, intra-abdominal pressure, abdominal infection, shock and related factors were analyzed by using univariate and Logistic regression to identify the independent risk factors of ARF after surgery in patients with simple abdominal trauma. Results Univariate analysis revealed statistical difference in aspects of blood transfusion volume ( ＞ 1 600 ml), operation timing ( interval between trauma and operation ＞12 h), preoperative shock duration ( ＞6 h), postoperative abdominal infection and intra-abdominal hypertension ( ＞ 12 mm Hg) between two groups ( P ＜ 0. 05 ). Logistic regression analysis showed that these five indices were the independent risk factors of ARF after surgery in patients with simple abdominal trauma ( P ＜ 0. 05 ). Conclusions Massive blood transfusion, delayed operation, long preoperative duration of shock, postoperative abdominal infection or intra-abdominal hypertension are the risk factors of ARF after surgery in patients with simple abdominal trauma. We should pay attention to these factors and take effective measures to prevent occurrence of ARF.
