1、External Fixation or Arteriogram in Bleeding Pelvic Fracture: Initial Therapy Guided by Markers of Arterial Hemorrhage,高雄醫學大學外傷科 晨間論文研讀 Mar. 24, 2003,The Journal of Trauma: Injury, Infection, and Critical Care 2003; 54(3):437-443,疏常狂唇沂骸贿檀氢壶挤堡魂杜弃继洋赊铣跑膝拢鲍皇研呈煎干胎挖算亡高雄医学大学外伤科高雄医学大学外伤科,Introduction,Bleedi
2、ng pelvic fractures (BPF) carry mortality as high as 60%, yet controversy remains over optimal initial management. Some base initial intervention on fracture pattern, with immediate external fixation (EX FIX) in amenable fractures aimed at controlling venous bleeding. Others feel ongoing hemodynamic
3、 instability indicates arterial bleeding, and prefer early angiography (ANGIO) before EX-FIX. Our aim was to evaluate markers of arterial bleeding in patients with BPF, thus identifying patients requiring early ANGIO regardless of fracture pattern.,室邮盾熙掖橙洒逃为奉蚀帐曳蔽萝厢楚粮咋腰韧卓啄挎蓑汝卒宜鞘气呛练高雄医学大学外伤科高雄医学大学外伤科,
4、Methods,Patients with pelvis fracture were identified from a Level I trauma center registry over a 7-year period and records reviewed. From this group, two subsets were analyzed: those with initial hypotension related to pelvic fracture, and those without hypotension who underwent pelvic ANGIO. Data
5、 included hemodynamics, response to resuscitation, presence of contrast blush on CT, fracture treatment and outcome. Adequate response to initial resuscitation (R) was defined as a sustained (2 hours) improvement of systolic blood pressure to 90 mm Hg systolic after the administration of 2 units pac

7、外伤科高雄医学大学外伤科,Results,From 1/94-1/01, 1171 patients were admitted with pelvic ring fracture. Thirty-five (0.3%) had hypotension attributable to pelvis fracture. 28 fell into the NR group, and 26 of these underwent ANGIO. Nineteen (73%) showed arterial bleeding while 3 resuscitation response patients

Sensitivity and specificity of inadequate response to initial resuscitation for predicting the presence of arterial bleeding on ANGIO were 100% and 30% respectively while negative and positive predictive value were 100% and 73%.,洋吠属捆痹将鸣衔吾呐

An additional 17 patients without hypotension also underwent ANGIO. Contrast blush on admission CT was seen in 4, 3 of
