“…At the 6-year follow-up, their DL CO decreased from 98.4% to 85.4% with no decrease in other lung volume parameters. 19 In the current study, patients with major burns concomitant with inhalation burns had reductions in FVC or FEV 1 (%), but DL CO (%) showed a more considerable reduction. Burgess et al 20 hypothesized that the presence of lesions in the vicinity of the alveoli and pulmonary vessels may explain this reduction in lung diffusion capacity.…”

This study aimed to evaluate pulmonary function measurements and respiratory muscle parameters in patients with major burn injury and smoke inhalation. The inclusion criteria included patients who were diagnosed with a smoke inhalation burn or a major burn of more than 20% of total body surface area (TBSA). All subjects underwent a pulmonary function test, respiratory muscle strength test, peak cough flow and fluoroscopic diaphragmatic movement measurement, and six-minute walk test before starting pulmonary rehabilitation. Evaluations were conducted on the 88 th days after the injury, the average time of admission to the Department of the Rehabilitation Medicine for burn rehabilitation after the completion of the acute treatment. The average degree of burns of the total 67 patients was 34.6% TBSA. All parameters in the patient group were significantly lower than the healthy controls, and a mild restrictive pattern of impairment with a reduction in diffusing capacity and more reduced expiratory muscle, than inspiratory muscle strength were observed. Peak cough flow, respiratory muscle strength, and forced vital capacity in the patient group with inhalation burn were significantly lower than in those without inhalation burn. The conditions of the majority of patients with major burn and inhalation injury were consistent with restrictive impairment and significant reduction in diffusion capacity. The patients had expiratory muscle weakness, decreased diaphragmatic movement, and exercise capacity impairment.

“…After the major burn has healed, the scars restricted the thorax, and the pulmonary reserve was lost [ 28 ]. Airflow obstruction degrees measured by FVC, FEV1, and FEV1/FVC%, restrictive disorder degrees measuring by TLC, and reduced DLco were observed in patients with inhalation injury [ 29 ]. The patients subsequently demonstrate a reduction in the DLco, FVC, and TLC for as long as several years after the injury [ 5 , 29 ].…”

“…The significance of physiologic tests for measuring DLco is that they permit the diagnosis of an impaired surface area for the transfer of gases [ 17 ]. Significantly low values of lung diffusing capacity in patients with smoke inhalation injury confirm the inhalation injury has an impact on the proof of gas exchange [ 29 ]. Deep breathing exercises are more effective in improving the ventilatory function in patients with inhalation injury than incentive spirometry exercises [ 39 ].…”

We performed pulmonary function (PF) tests and factors affecting PF evaluation in 120 patients with inhalation injury to evaluate the effects of pulmonary rehabilitation (PR) in burn patients with inhalation injury. Patients were randomized into pulmonary rehabilitation (PR) group and conventional rehabilitation (CON) group. PF tests, including forced vital capacity (FVC), 1-s forced expiratory volume FEV1), maximum voluntary ventilation (MVV), and respiratory muscles strength (maximal expiratory pressure (MEP) and maximal inspiratory pressure (MIP)), were measured by mouth pressure meter in the sitting position. Diffusing capacity for carbon monoxide (DLco) was determined by the single-breath carbon monoxide technique. Peak cough flow (PCF) was measured by a peak flow meter. Diaphragmatic mobility (DM) was evaluated on anteroposterior fluoroscopy. All evaluations were performed in all groups at baseline and after 12 weeks. There were no differences in evaluations between the PR group and CON group before the intervention. There were significant improvements in the PCF and MIP (%) changes, taken before and after rehabilitation in the PR group, compared with the changes in the CON group (p = 0.01, and p = 0.04). There were no significant changes in the other parameters in the PR group compared with the changes in the CON group (p > 0.05). There were significant differences in DLco (%), MIP, MIP (%), and DM between the PR group and the CON group (p = 0.02, p = 0.005, and p = 0.001) after 12 weeks of rehabilitation. There were no differences between the PR group and CON group after 12 weeks rehabilitation in the other parameters (p > 0.05). PR for patients with major burns and smoke inhalation induced improved PCF, MIP, MIP (%), DLco (%), and DM. These results show that PR should be a fundamental component of the treatment program for patients with burns.

Myocardial injury mimicking acute myocardial infarction from methane gas intoxication: a case report and literature review

Methane gas is a colorless and suffocating gas. We described the first case of methane gas intoxication in which the patient showed lethal myocardial injury. A 45-year-old man was presented to our hospital with unconsciousness after an accidental exposure to methane gas for 3 hours. On admission, serum troponin I was mild elevated. The initial electrocardiogram (ECG) showed sinus tachycardia. After 3 days, ECG showed diffuse elevation of the ST segment, and the patient developed refractory ventricular fibrillation (VF) and cardiac pump failure and died. However, coronary artery angiography showed that there was no occlusion. Therefore, it is possible that ischemic changes on the later ECG can predict in-hospital adverse cardiovascular events for methane gas intoxication.
