钝性腹部创伤早期临床特点及超声造影诊断效果研究

目的：探讨钝性腹部创伤患者早期临床特点及超声造影诊断实质性脏器损伤的效果。方法：钝性腹部创伤患者90例，来诊后在2h内分别进行腹部CT和超声造影检查。依据腹部CT结果将其分为3组：A组为腹腔存在实质脏器损伤且伴腹腔（盆腔）积液，B组为存在腹腔实质脏器损伤但无腹腔（盆腔）积液，C组无腹腔实质脏器损伤且无腹腔（盆腔）积液。分析3组患者早期临床特点，并将超声造影诊断结果与腹部CT诊断结果进行对比。结果：符合A组有26例，B组28例，C组36例。早期生命体征比较，除了A组心率要高于C组外（ P＜0．05），其他指标包括体温、血压均无显著性差异。血常规比较，A组血红蛋白要低于C组（ P＜0．05），B组与C组比较无显著差异。血气分析3组间均无显著性差异。超声造影诊断实质脏器创伤，A组符合率92．3％（24/26）， B组100％（28/28），C组100％（36/36），三组比较均无显著性差异。结论：钝性腹部创伤多合并不同程度实质性脏器创伤，存在腹腔（盆腔）积液者早期心率和血红蛋白可发生改变，超声造影对其早期诊断效果显著。

The Early Clinical Features and the Diagnosis Effect of Contrast Enhanced Ultrasound for Blunt Abdominal Trauma

Objective：To investigate the early clinical features and the diagnosis effect of contrast en-hanced ultrasound for blunt abdominal trauma .Method：All the ninety blunt abdominal trauma patients were analyzed .They were divided into three groups by their abdominal CT scanning results .Results： The vital signs of the blunt abdominal patients changed slightly in their early stage .Only the heart rate and hemoglobin level changed when liver or spleen ruptured accompanying abdominal bleeding .The diagnosis accurate rate was very high by using contrast enhanced ultrasound , which was more than 97.78%.Conclusion：Blunt ab-dominal trauma patients often accompanying solid organs rupture , and their vital signs changed slightly in the early stage .Using contrast enhanced ultrasound can enhance the diagnosis accurate rate .
