1、Abdominal Injury,the outline,the incidence of abdominal injuries in peacetime:0.4%-1.8%in wartime:50%the mortality of abdominal injuries is 10%,Types of the abdominal injuries,abdominal injury,open abdominal injury,closed abdominal injury,penetrating abdominal injury,non-penetrating abdominal injury
2、,Iatrogenic injury,Mechanism of closed injury,Direct impactDeceleration and rotational forcesSpleen,kidney,small bowel and liver are the most commonly closed abdominal injuried organs.,Mechanism of open injury,Stab woundsGunshot woundsLiver,small bowel,stomach and colon are commonly involved in the
3、open abdominal injuries.,The severity of the injuries and involved organs depend on the intensity,velocity,position and direction of the force.Abdominal anatomic features and the functions of the organs are also important to the injuries.,clinical manifestations,abdominal painhemorrhagic shockperito
4、nitis,abdominal organs injuries are divided to solid and hollow organs injuries.the main manifestation of the solid organs injuries is hemorrhage that can lead to shock.the main manifestation of the hollow organs injuries is peritonitis.,Hemorrhage and peritonitis can exist simultaneously,when the i
5、njuries involve the 2 kinds of abdominal organs.,Diagnosis,Accurate diagnosis and management requires a thorough history,physical examination,and,when indicated,laboratory tests.,when we diagnose the injury as the open abdominal injury,we should consider if there is a penetrating injury.,Diagnosis o
6、f the closed abdominal injury,Does the abdominal organ injury exist?Which organ is injuried?whether multiple organs are involved in the abdominal injuries?,when its still difficulty to diagnose,the following measures can be taken.,auxiliary examination,dignostic abdominal paracentesis and peritoneal
7、 Lavage,x-ray,Ultrasound,Abdominal computed tomography,MRI,angiography,diagnostic laparoscopy,observing closely determine the pulse rate,respiratory rate,blood pressure every 15-30 minutes.examine the abdominal signs every 30 minutes.determine the erythrocyte number,hemoglobin,hematocrit every 30-60
8、 minutes.,exploratory laparotomy,The indications for laparotomyAbdominal pain and peritoneal irritation sign aggravate gradually.Bowel tones becomes more weaker,even disappeared.The erythrocyte number and blood pressure are instability.Gastrointestinal bleedingRefractory shock,Management of the abdo

10、al cavity.Cover them with warm NS soaked gauze.,Antishock therapy is a key step in the therapeutic procedure.If given active antishock therapy,the shock still difficulty to correct,it suggests that there is progressive intraperitoneal hemorrhage,the exploratory laparotomy is necessary.,In principle,
11、the laparotomy should explore the abdominal organs in order as the following:the solid organs diaphragma stomach duodenum jejunumileummesentery pelvic organs posterior surface of stomach panceas,Splenic rupture,The spleen remains the most commonly injured organ.in closed injury:20%40%in open injury:
