AbstractObjective: To introduce the experience in treating burn patients with inhalation injury during the epidemic of coronavirus disease 2019 (COVID-19). Methods: Six burn patients combined with inhalation injury were hospitalized in Department of Burns of Tongren Hospital of Wuhan University & Wuhan Third Hospital from February 1 to March 1 in 2020 during the high-incidence period of COVID-19, including 4 males and 2 females, aged 21-63 years, admitted at 2-4 hours after burns, with total burn areas of 1%-20% total body surface area (TBSA) and full-thickness burn areas of 1%-12% TBSA. Among them, 1 case had severe inhalation injury, 2 cases had mild inhalation injury, and 3 cases had moderate inhalation injury. The body temperatures of the patients were normal at the time of admission, with no fever or cough in the past 2 weeks. At admission, chest CT of one patient showed double lower lobes and left upper lobes had multiple slices and slightly high-density shadow of nodules. Chest CT of two patients showed thickening of bilateral lung texture, and the chest CT of remaining patients were normal. After admission, 6 patients were given routine treatment, the medical staffs paid attention to the protection and screened for COVID-19 according to the diagnosis and treatment plan of COVID-19. On post injury day (PID) 1, 3, 6, and 9, vein blood of patients were collected for determination of white blood cell (WBC) count, neutrophil, lymphocyte absolute value, and level of procalcitonin (PCT). Nucleic acid of novel coronavirus was detected by real-time fluorescence quantitative reverse transcription polymerase chain reaction on PID 3 and 6. The temperatures of patients were recorded after admission. The results of chest CT within one week after injury and the prognosis of the patients were recorded. Measurement data distributed normally were expressed as x±s, and measurement data distributed abnormally were expressed as M(P(25), P(75)). Results: (1) On PID 1, 3, 6, and 9, WBC counts of patients were respectively (19.8±3.8)×10(9)/L, (17.2±3.4)×10(9)/L, (13.3±3.1)×10(9)/L, and (11.1±1.6)×10(9)/L, neutrophils of patients were respectively 0.919±0.019, 0.899±0.011, 0.855±0.034, and 0.811±0.035, absolute values of lymphocytes of patients were respectively (0.65±0.18)×10(9)/L, (0.65±0.24)×10(9)/L, (0.91±0.34)×10(9)/L, and (1.23±0.42)×10(9)/L, and PCT values of patients were respectively 0.49 (0.36, 1.64), 0.39 (0.26, 0.73), 0.28 (0.18, 0.33), and 0.12 (0.11, 0.20) ng/mL. The values of WBC and neutrophils of patients were higher than the normal value, showing a downward trend. The absolute values of lymphocyte of patients returned to the normal value from PID 6. The PCT values of patients were higher than the normal value. (2) Nucleic acid test results of novel coronavirus of 6 patients were negative on PID 3 and 6. The temperatures of 6 patients ranged from 36.5 to 38.6 ℃. The typical imaging features of COVID-19 were not found in 6 patients within 1 week after injury by chest CT. After treatment for 14-32 days, 6 patients were cured and discharged. Conclusions: During COVID-19 pandemic, burn patients combined with inhalation injury should be treated under condition of good protection for doctors and nurses. Meanwhile, virus should be actively screened to reduce the risk of COVID-19 infection among doctors and patients.
