Early FAST Examinations during Resuscitation May Compromise Trauma Outcomes.

ABSTRACT

Focused assessment with Sonography for trauma (FAST) examination is essential to trauma triage. We sought to determine whether FASTs completed early in sequencing portend worse outcomes. A two-year review (2014-2015) of all trauma activations at our Level I trauma center was performed. Patients were matched at baseline and FAST times were compared. Outcomes included resuscitation time (RESUS-h), ventilation days (d), hospital length of stay (HLOS-d), ICU length of stay (LOS-d), survival (%), nosocomial infection rate (%), and venous thromboembolism complication rate (%). ED interventions included transfusions, crystalloid, antibiotics, central line placement, intubation, thoracostomy, thoracotomy, pelvic X-ray, and binder. One thousand, three hundred and twelve patients were included for analysis (mean age = 38 ± 19 years, mean Injury Severity Score = 12 ± 11, 21% penetrating). Compared with FASTs completed after the primary survey, early FASTs led to significantly more ventilation days (P < 0.01), longer ICU length of stay (P < 0.01), and a greater incidence of nosocomial infections (P = 0.03). In the ED, early FASTs led to significantly more intubations (P < 0.01) and transfusions (P < 0.01) compared with late FASTs. FASTs completed before primary survey portend worse outcomes, with more ED interventions and equivocal results. FAST as a true adjunct to primary survey is recommended.
