Pediatric trauma accounted for 59.5% of all mortality for children under 18 in 2004. In the US approximately 16,000,000 children go to a hospital due to some kind of injury every year. Male children are more frequently injured then female children by a ratio of two to one. The direct costs alone of childhood injury exceed eight billion dollars per year.

Slide 5

Pediatric multiple trauma victims present a unique set of problems to the emergency physician, pediatrician, or surgeon. Children rarely sustain lethal injury; however, delayed recognition and inappropriate management of the common problems encountered in the pediatric trauma patient can lead to a poor outcome.

Slide 8

Infants and young children, in particular, have a relatively large body-surface-area-to- body-cell mass ratio and are thus prone to developing hypothermia. Young children have relatively large heads. The glottis lies in a more superior and anterior position relative to the pharynx. This makes orotracheal intubation much easier than nasotracheal intubation,

Slide 9

Slide 10

In children, the thorax is much more compliant to external forces and the vital organs are closer to the surface, both of which tend to increase the risk of blunt injury to the tracheobronchial tree, the heart, and great vessels. the mediastinum is more mobile so that an increase in pressure from a pneumothorax or hemothorax on one side is more apt to compromise both lungs.

Slide 13

the liver, spleen, and kidneys are less well protected by the ribs in children because the ribs are more pliable and because these organs are less well covered by the ribs.

Slide 14

Slide 15

Movement of the neck, as is commonly employed to provide an airway,can convert a bony or ligamentous injury into a permanent disability. *C-spine protection should be initiated at the scene and maintained in the emergency department.

Slide 16

Slide 17

Children are much more susceptible to hypothermia than adults Be very aggressive in preventing and managing hypothermia

Slide 21

the Broselow System :is a reasonable method of organizing the trauma room. This system provides color-code dequipment : *airways, laryngoscopes, endotracheal tubes, suction catheters, vascular access devices, nasogastric (NG) tubes, urinary catheters, chest tubes. The color-coding is based on the childs weigh

Slide 25

Usual ABCs, and C-spine Use your Broselow Weight can also be estimated: < 8: (AGE x 2) + 8 > 8: AGE x 3

Slide 26

Before a child leaves the trauma room for a diagnostic procedure, they must have their ABCs assessed and stabilized

Slide 28

8% to 12% of blunt injured children will have abdominal injury. Good news>>>>>: 90% of those with blunt abdominal injuries survive 22% of the deaths are related to the abdominal injury

Slide 30

The spleen and liver are the organs most commonly injured in blunt abdominal trauma with each representing one-third of the injuries. Abdominal CT is the most useful diagnostic test because it produces images that define the presence and extent of splenic and hepatic injury and associated changes.

Slide 31

spleen and liver: 90% conservative: admit, observe, Hct more fatal hemorrhage with liver injuries laparotomy in unstable after resussitation. hematuria: gross or >20 RBC + unstable IVP in OR >10 RBC + stable CT- cystoscopy.

Slide 32

most widely used stable patients only Low sensitivity for hollow viscous (25% sens), pancreas (85% sens)

Slide 33

Rarely needed in pediatric. +ve: >100,000 RBC (blunt in adult, in pediatric it is controversial ). FP 5-14%.?

Slide 34

The decision to operate for spleen or liver injury, which should always be made by a surgeon, is best based on clinical signs of continued blood loss such as low blood pressure, elevated heart rate, decreased urine output, and falling hematocrit.

Slide 35

It has been suggested that non operative management of blunt splenic injuries requires more blood transfusion than operative hemostasis. In fact, many studies showed that in children: conservative treatment had a significantly lower rate of transfusion compared to a group of hemodynamically stable patients undergoing celiotomy for blunt splenic injury

Slide 36

Two recent studies of more than1100 patients with isolated spleen or liver trauma showed a tranfusion rate of less than 5% in children with grade IIII injuries. a low hematocrit alone is not an absolute indication for transfusion.

Slide 37

Slide 38

There is no justification for an exploratory celiotomy solely to avoid missing potential associated injuries in children.

Slide 39

Children hemodynamic instable. evidence of persistent hemorrhage. Suspicion of hollow viscus perforation. major pancreatic ductal disruption.

Slide 40

A recent report of 328 children with liver injury revealed that hemodynamic instability, as defined by the need for blood transfusion in excess of 25 mL/kg within the first two hours of presentation, was a strong indicator of the need for surgical intervention and hepatic vascular injury

Slide 41

Most liver injuries requiring operation are amenable to simple methods of hemostasis using some combination of manual compression, suture, and topical hemostatic agents

Slide 42

Slide 43

*I Hematoma Subcapsular, 3 cm parenchymal depth *IV Laceration Segmental or hilar vessels; devascularization >25% spleen *V Laceration Completely shattered spleen Vascular Hilar injury which devascularizes spleen

Slide 44

1% - 4% of intraabdominal injuries in children sustaining blunt trauma. blunt injury to the duodenum occurred in about (0.2%), of whom only (14.56%) had full-thickness rupture.

Slide 45

Slide 46

Slide 47

Injuries to the pancreas are slightly more frequent than duodenal injuries with estimated ranges from 3% to 12% in children sustaining blunt abdominal trauma

Slide 48

Slide 49

Slide 50

*Blunt trauma is more common, accounting for greater than 90% of injuries. *Penetrating trauma accounts for 1020% of renal injuries

Slide 51

grade I renal contusion or nonexpanding subcapsular hematoma without a renal parenchymal laceration; grade II non-expanding perirenal hematoma a renal cortex laceration (l cm) and no urinary extravasation; grade IV renal cortical laceration extending into the collecting system (as noted by contrast extravasation), or a segmental renal artery or vein injury (noted by segmental parenchymal infarct), or main renal artery or vein injury with a contained hematoma; grade V shattered kidney, avulsion of the renal pedicle, or thrombosis of the main renal artery

Slide 52

Slide 53

Injury to the urinary tract occurs in 310% of patients suffering from blunt or penetrating trauma

Slide 54

Slide 55

Trauma is still the most important cause of mortality in pediatrics. Assessment in the first golden hours is very important in preventing or decreasing this mortality. Observation..reassessment are the main keys in the management of the majority of cases of blunt trama in children
