Brief Summary

Blunt vascular trauma to the lower extremity has been associated with injuries to the anteroposterior tibial arteries or popliteal artery in the form of transection, occlusion, or intimal injury. With many blunt injuries resulting in orthopedic fractures, the incidence of limb loss increases substantial. Distal vascular injuries combined with complex orthopedic fractures are more likely to result in limb loss. A recent retrospective study showed two main predicative factors resulting in limb loss was a result of multi-segmental bone fractures and prolong ischemic time greater then 10 hours.

Outcome Measures

Primary Outcomes (4)

  • Mortality

    Incidence of mortality associated with transfer status

    Measured in the first 30 days of admission

  • Length of total hospital stay

    The time spent hospitalized in days.

    Length of total hospital stay from admission in the hospital is defined as the time frame between admission and discharge. The time frame of collection until the event occurred was 180 days.

  • Operative Cases

    The total operative cases required for a patient

    Time frame is from admission to discharge and would be collected in the first 180 days.

  • Admission lactate levels

    Admission lactate levels were defined as the first measured lactate level on admission of an individual who presented as a trauma patient.

    he estimated period of time over which preoperative lactate levels are measured occur in the initial 2 hours after admission to the hospital

Study Arms (2)

Transferred from Outside Hospital

Patients with blunt or penetrating trauma that are transferred from an outside hospital to admitting level 1 trauma center

Other: Packed Red Blood Cell Administration

Direct Admission to Hospital

Patients with blunt or penetrating trauma that are directly brought to level 1 trauma center

Other: Packed Red Blood Cell Administration

Interventions

Difference in occurrence of mortality in patients transferred versus directly admitted who have packed red blood cell administration in the first four hours of arrival to the hospital.

Direct Admission to HospitalTransferred from Outside Hospital

Study Population

This study was completed at the Arrowhead Regional Medical Center (ARMC) in San Bernardino County, California. The ARMC is a 456-bed acute-care teaching facility and ACS-verified level I trauma center. The ARMC emergency department (ED) is one of the busiest in the state of California with more than 100,000 visits and over 3,000 adult trauma cases annually.

You may qualify if:

  • All patients aged 18 years or higher with blunt or penetrating extremity trauma injuries

You may not qualify if:

  • Pregnant females with blunt or penetrating extremity trauma injuries
  • Catastrophic head injuries
  • Individuals discharged from the hospital in the first 24 hours of being seen
