Aspiration pneumonia: an underestimated cause of severe respiratory failure in patients with haematological malignancies and severe oral mucositis?

Non-ventilator health care associated pneumonia (NV-HAP): Oncology

Literature suggests that cancer patients can become colonized or infected with a variety of opportunistic and health care-associated pathogens, putting them at higher risk for nonventilator health care-associated pneumonia. This section will review the epidemiology of nonventilator health care-associated pneumonia and the importance of prevention strategies in this vulnerable population. Prevention strategies for cancer patients across the continuum of care are highlighted.

Detection of myocardial enzymes, cardiac troponin T and hepatic and renal function in the diagnosis and treatment of severe pneumonia in children

OBJECTIVE

To analyze the significance of myocardial enzymes, cardiac troponin T (cTnT) and hepatic and renal function in the treatment of severe pneumonia in children.

METHODS

One hundred and twenty children with severe pneumonia who were admitted to the hospital between April 2015 and February 2017 were selected and included as a severe pneumonia group; 120 children with common pneumonia were included as a common pneumonia group; 100 healthy children were included as controls. The myocardial enzymes, cTnT and hepatic and renal function of patients in the three groups were detected and compared. The children with severe pneumonia were divided into a mild hypoxia group, a moderate hypoxia group and a severe hypoxia group according to arterial partial pressure of oxygen; the myocardial enzymes, hepatic and renal function and cTnT of the children in the three groups were compared. The correlations of partial pressure of blood oxygen with myocardial enzymes, hepatic and renal function and cTnT were analyzed.

RESULTS

The levels of myocardial enzymes, hepatic and renal function and cTnT of the severe pneumonia group, common pneumonia group and control group declined, and the differences had statistical significance (P<0.05). The levels of myocardial enzymes, hepatic and renal function and cTnT were higher in the children with severe hypoxia. The partial pressure of blood oxygen was in a negative correlation with myocardial enzymes, hepatic and renal function and cTnT in the severe pneumonia group.

CONCLUSION

Timely monitoring of myocardial enzymes, hepatic and renal function and cTnT has an extremely important role in the evaluation of children with severe pneumonia.
