Table 3 Patients classified by base deficit (classes I to IV): laboratory findings

From: Renaissance of base deficit for the initial assessment of trauma patients: a base deficit-based classification for hypovolemic shock developed on data from 16,305 patients derived from the TraumaRegister DGU®

  Class I Class II Class III Class IV
  BD ≤ 2.0
(no shock)
BD > 2.0 to 6.0
(mild)
BD > 6.0 to 10.0
(moderate)
BD > 10.0
(severe)

Hemoglobin, g/dL 12.8 (2.4) 11.8 (2.6) 10.6 (2.9) 9.1 (3.3)
Thrombocytes, tsd/μL 215 (74) 208 (77) 193 (81) 171 (82)
