RESUMO
Objective To investigate the availability and safety of pulmonary rehabilitation for hospitalized patients with acute exacerba-tion of chronic obstructive pulmonary disease (COPD). Methods Seventy-two hospitalized patients with acute exacerbation of COPD were randomly included into test group (n=36) and control group (n=36) from June, 2015 to June, 2016. All the patients accepted management of anti-infection, phlegm elimination, antiasthma, etc., as well as the guidance of expectoration and health education; while the test group ac-cepted pulmonary rehabilitation from the third day of admission to discharge. Their strength of hand grip, 1-minute sit-to-stand test (STST), the days of hospitalization, lung function parameters, modified Medical Research Council (mMRC) scores and COPD Assessment Test (CAT) scores were measured before and after treatment. Results Compared with the control group, the strength of hand grip (t=2.985, P0.05). There was no significant difference in lung function after treatment in both groups (Z0.05). Conclu-sion Pulmonary rehabilitation is effective on hospitalized patients with acute exacerbation of COPD in muscle strength, capability of activi-ties, and relieve the symptoms.
RESUMO
Objective To investigate the distribution of pathogens isolated from lower respiratory tract sputum samples of trach‐eotomy patients who suffered from severe craniocerebral injury and nurses′hands surface samples ,and analyze the correlation be‐tween them .Methods Lower respiratory tract sputum samples of 97 tracheotomy patients suffered from severe craniocerebral inju‐ry and hands surface samples from nurses who just washed their hands after the sample collection were collected .Then the samples were sent to the microbiological lab for pathogen isolation and identification ,the results were statistically analyzed by using WHO‐NET5.4software.Results 388sampleswerecollectedaltogether,including194sputumsamplesand194nurses′handssurface samples .633 pathogens were isolated altogether ,including 452 strains of G- bacteria (71 .41% ) ,134 strains of G+ bacteria (21 .17% ) and 47 strains of fungi(7 .42% ) .The top five species of G- bacteria which took the largest proportion and caused the lower respiratory tract infection were Peudomonas aeruginosa(12 .16% ) ,Acinetobacter baumannii(9 .63% ) ,Klebsiella pneumoniae bacteria(7 .10% ) ,Stenotrophomonas maltophilia(5 .21% ) ,Escherichia coli(4 .89% );the primary species of G+ bacteria were coag‐ulase negative staphylococcus(6 .79% ) ,Staphylococcus aureus(2 .36% );the primary fungus was Monilia albicans(4 .24% ) .The top five G- bacteria species which took the largest proportion and isolated from hands surface samples were Pseudomonas aeruginosa (6 .79% ) ,Acinetobacter baumannii(5 .84% ) ,Escherichia coli(4 .91% ) ,Klebsiella pneumoniae(3 .94% ) ,Stenotrophomonas malto‐philia(3 .79% );the primary species of G+ bacteria were coagulase negative staphylococcus (9 .63% ) ,Staphylococcus aureus (2 .36% ) .The primary fungus was Monilia albicans(3 .00% ) .Conclusion Tracheotomy patients who suffered from severe cranio‐cerebral injury with lower respiratory infection are very possible to have cross‐infection ,sanitary management of nurses′hands asep‐tic manipulation procedures should be strengthened .
