目的：分析术前凝血试验应用于口腔颌面患者手术出血的意义。方法：选取2011年5月-2012年7月本院口腔科收治的100例口腔颌面手术患者为研究对象，根据术前的凝血试验将其分成两组：凝血功能异常35例（异常组），凝血功能正常65例（正常组）。对比分析两组患者出血量、手术时间以及相关临床事件的关系。结果：正常组术中出血量为（388.7±225.3）mL，异常组为（397.8±223.6）mL，两组比较差异无统计学意义（P>0.05）；正常组手术时间（3.2±1.2）h，异常组为（2.4±1.3）h，两组比较差异具有统计学意义（P<0.05）；相关临床事件方面，正常组改变或延缓手术0例，因出血使用的全身性止血剂2例（3.1%）；异常组分别为22例（62.9%）、20例（57.1%），两组上述指标比较差异具有统计学意义（P<0.05），其他各项相关临床事件均无明显差异（P>0.05）。结论：术前凝血试验对预测口腔颌面手术出血量及相关临床事件没有相关性，但可以预测口腔颌面凝血功能异常患者的有关出血性并发症情况，具有一定的借鉴意义。%Objective:To analyze the meaning of preoperative coagulation tests used in bleeding of patients with oral and maxillofacial surgery. Method:100 patients underwent oral and maxillofacial surgery in our hospital from May 2011 to July 2012 during were selected for the study. According to preoperative coagulation tests would be divided into two groups:35 patients with coagulation abnormalities(abnormal group),65 cases of normal blood clotting function(normal group). Surgical time and blood loss related clinical events unfold of two groups were analyzed. Result:In the normal group,with an average blood loss was(388.7±225.3)mL,operative time was(3.2±1.2)h;the abnormal group,with an average blood loss was (397.8±223.6)mL,operative time was(2.4±1.3)h. The bleeding little difference of two groups was not statistically significant(P>0.05),the difference of operative time had statistically significant(P<0.05). Related clinical events,change or delay surgery of the normal group was 0 case,due to bleeding used systemic hemostatic in 2 cases(3.1%);the abnormal group were 22 cases(62.9%)and 20 cases(57.1%),the differences were statistically significant(P<0.05),all other relevant clinical events had no difference(P>0.05). Conclusion:Preoperative coagulation tests for predicting the amount of bleeding in patients with oral and maxillofacial related clinical events with most aspects of no correlation,but it can predict coagulation abnormalities in patients with oral and maxillofacial some related bleeding complications,has certain clinical reference.
