Albright JM et al. The acute pulmonary inflammatory response to the graded severity of smoke inhalation injury. Crit Care Med. DOI: 10.1097/CCM.0b013e3182374a67. PMID: 22067627. Table 1 prints the bronchoscopic Abbreviated Injury Score grades. Grade 0, AIS code 919201.2, no injury: absence of carbonaceous deposits, erythema, edema, bronchorrhea, or obstruction. Grade 1, AIS code 919202.3, mild injury: minor or patchy areas of erythema, carbonaceous deposits in proximal or distal bronchi. Grade 2, AIS code 919204.4, moderate injury: moderate degree of erythema, carbonaceous deposits, bronchorrhea, or bronchial obstruction. Grade 3, AIS code 919206.5, severe injury: severe inflammation with friability, copious carbonaceous deposits, bronchorrhea, or obstruction. Grade 4, AIS code 919208.6, massive injury: evidence of mucosal sloughing, necrosis, endoluminal obliteration. The paper compares grades 1–2 with grades 3–4 and grade 0 with grades 1–4. (2012)

Scope: Burn-injured patients who undergo bronchoscopy for suspected smoke inhalation. The grade is assigned from the bronchoscopic description in Table 1.
