Q

what are the steps in primary survey & resuscitation?

A
  • airway - make sure it is patent & protected

Q

what is the aim of ultrasound in trauma?

A

to detect present of free fluid

advantages:
* non-invasive
* repeatable, intial eval
* no radiation
* low cost

Q

what is done in focus assessment with sonography (FAST)in trauma?

A
  • check 4 windows: R subcostal, Subxiphoid, L subcostal, Suprapubic
  • look at subhepatic space, pericardial window, left upper quadrant, pelvis
19
Q

what is done in Extended focus assessment with sonography in trauma (EFAST)?

A
  • pleural cavities, visualize any fluid in the chest
  • if there is hemothorax & pneumothorax -> chest tube must be inserted
20
Q

When do u do a diagnostic peritoneal lavage?

A
  • if utlrasound cannot be done
  • unexplained shock or hypotension
  • altered sensorium
  • gen anesthesia for extra-abdominal procedures
  • spinal cord injury
21
Q

what are C/Is of Diagnostic Peritoneal Lavage?

A
  • clear indication of surgery
  • relative: pregnancy, obesity, previous abdominal surgery
22
Q

what are the results of a positive peritoneal lavage?

A
  • aspiration of atleast 10mL gross blood
  • bloody lavage effluent
  • RBC >100,000mL3
  • WBC >500mL3
  • amyalse >19IU/dL
  • bile, bacteria, food fibers
23
Q

what technique involves more than simple visualization w/ scope & requires multiple ports and manipulation of the tissues?

A

diagnostic laparaoscopy

24
what are the different liver injury scale?
* **Grade I **= Hematoma, Laceration: Sucapsular <10^ SA, <1cm deep capsular tear * **Grade II** = Hematoma, laceration; 10-15% SA subcapsular, <10cm diam; 1-3cm deep, <10cm long capsular tear * **Grade III **= Hematoma, Laceration: >50% SA, >10cm, laceration is 3cm deep * **Grade IV** = Laceration = parenchymal disruption of 25-75% or >3% segments * **Grade V** = >75% lacteration, Vascular: juxtahepatic venous injuries * **Grade VI **= hepatic avulsion
25
what are the different liver injury scale?
* **Grade I **= Hematoma, Laceration: Sucapsular <10^ SA, <1cm deep capsular tear * **Grade II** = Hematoma, laceration; 10-15% SA subcapsular, <10cm diam; 1-3cm deep, <10cm long capsular tear * **Grade III **= Hematoma, Laceration: >50% SA, >10cm, laceration is 3cm deep * **Grade IV** = Laceration = parenchymal disruption of 25-75% or >3% segments * **Grade V** = >75% lacteration, Vascular: juxtahepatic venous injuries * **Grade VI **= hepatic avulsion
26
what are the tx of liver injuries?
* expectant/observatoin * drainage * hepatorrhapy * debridement/reseection * packing * angiography/embolization
27
what is the step of BLS where injured organs are repaired or removed?
defintiive care
28
on what criteria do we sort in triage?
* urgency * probability of survival * availability & capability of the resources
29
what are the diff priorities in the triage?
* **1st priority** = immediately life-threatening injuries * **2nd priority** = major system injuries require treatment wihin 1 hr * **3rd priority** = walking wounded * **4th priority** = not expected to survive, near dead
30
what is lethal triad needed to do damage control?
hypothermia acidosis coagulopathy
31
what are common scenarios where damage control is done?
* stable px with >2 of triad * hypotensive px w/ >1 of triad * mass casualty incident * anticipated need for massive transfusion * shortage of blood product supply * complex multisystem injuries
32
what are the phases of damange control?
* **Phase 1** = ER assessment, decide to do damage control * **Phase 2**= damage control surgery, surgical control of hemorrhage & contaminatio * **Phase 3** = ICU resuscitation, correction of hypthermia and coagulopathy in ICU * **Phase 4** = repoeration with def surgical managenet of intra-abdominal injuries
33
what are the diff types of hazards
natural technological biological societal
34
what are the diff disasters in the NDRP?
* I = hydro-meterological hazards * II = seismic hazards: earthquakes, landslides * III = tsunami * IV = volcano * V = pandemic/epidemic * others = fiore, transpo, pollution, civil disturbance, etc
35
what is the risk formula?
risk = [(hazard x vulnerability)/capacity]
36
what is an actual threat to public safety and or public health?
emergency
37
what are the different factors that can determine the type and severity of consequences?
* community * capacity * vulnerability
38
what is the RA of National disaster irsk reduction management?
RA 10121
39
what is the cycle of disaster?
* prep for disaster * disaster occurrence * disaster response * recovery from disaster * mitigation against the impact of future disasters * risk reduction agsint the future disasters * prevention of future disasters * preparation for next disaster
40
what is the part of disaster management cycle where it eliminates or reduces the probability of disaster occurrence
prevention
41
what is the part of disaster management cycle where activties are reduced to either chance of hazard taking place or turning into a disaster?
mitigation - building codes - zoning and land use management - regulations and safety codews - preventive health care - public education
42
what is the management system used in responding to an incident?
incident command system (ICS) | only 1 person is in-charge
43
what are the 2 types of ICS?
single commant = 1 agency unified command = several agencies | q
44
what are the different color tags?
* **red** = immediate care, 1st for evacuation, life-threatening * **yellow** = needs care, not life-threatening, urgent condition * **green** = 3rd, minor injuries, delayed conditions * **blue** = 3/4th, near dead, after red & yellow condition * **black & white** = dead
