In massive transfusion protocol from suspected hemorrhage, is it worth obtaining a TEG to guide transfusion?
There really is no evidence (except expert opinion) on massive transfusion protocols and outcomes. There are a few trials showing that TEG or other viscoelastic tests reduce transfusion and even improve survival or other important outcomes in hemorrhage. So given the choice, if rapid point of care T...
Do you use spO2 to define ARDS in patients with darker skin pigmentation?
That's an excellent question and highlights some different approaches to define, and thus provide appropriate early treatment for, patients with ARDS.For many years, clinicians have been using a framework designed in 2012 and referred to as the Berlin Definition to define and classify ARDS (Ranieri ...
Do you ever stop tobramycin prophylaxis in a patient with chronic bronchiectasis previously colonized with pseudomonas?
Yes, I will often stop tobramycin if there are issues with tolerance, antibiotic resistance, or treatment fatigue. Further, in more mild bronchiectasis (cylindrical vs. varicoid or cystic morphologies), sputum bacterial cultures will negatively convert on chronic cycled inhaled tobramycin, and this ...
How do you manage persistent pseudomonas positive sputum a patient with non-CF bronchiectasis who has chronic sputum production but is otherwise asymptomatic?
I am assuming the Pseudomonas has persisted despite efforts to eradicate early on; if not, I would consider at least an effort at "eradication" or at least aggressive treatment. If the Pseudomonas has persisted and the person feels well other than sputum production, would aggressively pursue airway ...
What is your preferred forceps size for transbronchial biopsies, considering options ranging from 1.8 to 2.8mm?
This question depends on the clinical situation. Generally speaking, I'll use a forceps that is 1.9mm in diameter for most cases, as it has the ability to fit through any of our bronchoscopes and can usually provide adequate tissue. Occasionally, if more tissue is required, you can consider the use ...
Do you seek pathologic confirmation before proceeding with empiric immunosuppressive therapy in symptomatic patients with radiographic NSIP?
In general, getting lung biopsies is needed in a minority of people who have clear evidence of NSIP on HRCT. If there is any evidence to suggest a concomitant ARD, a biopsy will not typically be needed. In our combined ILD-Rheumatology clinic, we see these patients all the time and I can think of on...
Would you consider antifungal prophylaxis for immunocompromised patients with COVID-19 requiring mechanical ventilation, considering the high risk of invasive pulmonary aspergillosis in patients with severe COVID-19?
I don't universally add anti-mold prophylaxis in all immunocompromised patients with severe COVID-19 requiring intubation, but I am always considering it. Factors that might push me to add would be: positive fungal markers (Beta-D-Glucan or galactomannan) on BAL or blood at time of intubation, use o...
When interpreting pulmonary function tests (PFTs), do you include diagnostic language such as 'findings are suggestive of COPD,' or do you limit your report to a descriptive interpretation of the data?
My viewpoint is that PFT interpretation should focus on interpreting physiology. This is especially important in areas like airway diseases, where a post-bronchodilator FEV1/FVC ratio showing obstruction could be due to a host of diseases. If the interpreter puts that is suggestive of COPD without t...
Do you always get a baseline chest xray in patients who will be starting methotrexate?
I believe it is a good practice for screening CXR before Mtx to document baseline findings, which will help to register if there is some baseline issues.
How do you mitigate risk when performing bronchoscopy in hypoxic patients requiring high levels of supplemental oxygen?
The first question you have to ask yourself, is 'why am I doing this'? If the answer is not going to significantly alter management (i.e. removal of a foreign body, bronchus plug; or biopsy to alter drug therapy) then it would be wise to defer until the patient is more stable. If it is deemed the pr...
