RESUMO
Diaphragm paralysis may be either idiopathic or associated with several medical conditions including viral and bacterial infection. The association of phrenic nerve palsy with viral infections is rare but well-appreciated in several case reports. Neuropathy, both central and peripheral, is a common neurological consequence of COVID-19. Here, we describe a case of diaphragm paralysis in a woman who was admitted to the hospital because of COVID-19 pneumonia. Post-COVID-19 unilateral paralyzed diaphragm was diagnosed with a chest X-ray for her and the disorder was attributed to COVID-19 because no other etiology was found to be associated. So far, phrenic neuropathy and diaphragmatic paralysis in a COVID-19-affected patient have not been reported from Iran.
RESUMO
Background: Inspiratory muscle training has been introduced as one of the effective methods in pulmonary rehabilitation, and attention to this technique in patients with COVID-19 is still being studied. Materials and Methods: In the present study 52 patients who have undergone the period of the COVID-19 disease were randomly divided into two groups. In the control group, in addition to the routine treatment prescribed by a specialist physician, rehabilitation was performed by performing diaphragmatic breathing exercises, pursed-lips breathing, chest expansion, and simple stretching exercises. In the intervention group in addition to the rehabilitation program provided to the control group, patients used an inspiratory muscle training device. This pulmonary rehabilitation program was performed twice a day and 30 repetitions each time with a two-minute rest after every 10 exercises. After 4 weeks, patients in both groups were referred to the hospital for reassessment of the distance of the 6-minute walk test, SF-12 questionnaire results, dyspnea, and S-index. To compare quantitative variables between the two groups we utilized a student t-test. Type one error was put at P≤0.05. Results: The comparison of 6MWT values shows that the mean of this index in the intervention group is significantly higher than the control group (p = 0.002). Also, the S-index of the two groups showed a significant difference (p=0.024). Results show a significant increase in the SF-12 quality of life questionnaire in patients using IMT (p=0.001). Conclusion: IMT improves pulmonary functions, 6MWT, and SF-12 Questionnaire in recovered COVID-19 patients.
RESUMO
More than a year after the onset of the coronavirus disease pandemic in 2019, the disease remains a major global health issue. During this time, health organizations worldwide have tried to provide integrated treatment guidelines to control coronavirus disease 2019 (COVID-19) at different levels. However, due to the novel nature of the disease and the emergence of new variants, medical teams' updating medical information and drug prescribing guidelines should be given special attention. This version is an updated instruction of the National Research Institute of Tuberculosis and Lung Disease (NRITLD) in collaboration with a group of specialists from Masih Daneshvari Hospital in Tehran, Iran, which is provided to update the information of caring clinicians for the treatment and care of COVID-19 hospitalized patients.
