What clinical features guide your choice between ketamine and etomidate in patients with septic shock who require rapid sequence intubation given recent data suggesting no difference in 28 day mortality?
Given the lower risk for hypotension with use of etomidate vs. ketamine, I usually use etomidate. I find the onset of action is more predictable. In our medical intensive care unit (MICU), the only time I reach for ketamine for rapid sequence intubation (RSI) is if patients have bronchospasms.
What has been your stepwise approach to oxygenation, including when to consider the use of inhaled nitric oxide or epoprostenol, in refractory hypoxemia due to cardiogenic pulmonary edema in patients who are otherwise not ECMO candidates?
Stepwise Approach to Oxygenation in Refractory Hypoxemia Due to Cardiogenic Pulmonary Edema: Initial Stabilization and Oxygen Therapy: Start with supplemental oxygen to maintain SpOâ‚‚ > 90%. Use noninvasive ventilation (NIV), such as CPAP or BiPAP, to provide positive end-expiratory pressure (PEE...
Which biologics for asthma have data regarding mucus plugging?
There have been multiple studies on biologics investigating the effects on mucus plugging (as measured by the CT mucus plug score of the number of pulmonary segments with a mucus plug, established by Dunican et al., PMID 29400693). In these studies, high mucus plug scores correlate with T2 high biom...
Do you utilize cytokine panels to guide treatment of patients with EGPA?
Whether biomarkers can guide treatment decisions or predict disease relapse is a critical area of study in ANCA associated vasculitis. However, efforts to identify biomarkers that are predictive in EGPA are at an early stage currently. There have been multiple negative studies of biomarkers being ab...
What is your preferred rescue inhaler for patients with asthma?
SMART with ICS/formoterol. I tend to think all asthma patients should be on SMART therapy (ICS/formoterol). Just don't really see the reason to not treat that way.
When have you found the Nidra TOMAC device to be helpful for refractory restless leg syndrome?
I have one patient who found it helpful with breakthrough symptoms in refractory RLS, but was unable to get enough coverage to continue using it.
Do you adhere to the standard 5-day minimum treatment duration for community-acquired pneumonia, or have you used shorter courses for certain low-risk patients?
This is a question addressing a shorter duration of antibiotic therapy than the current IDSA guidelines for community-acquired pneumonia (CAP) recommend. It has been the topic of several studies, for example, 3-day treatment (Richard T. Ellison III, MD, reviewing Dinh et al., PMID 33773631; Niederma...
How do you approach management of an ICU patient with brief potentially ictal rhythmic discharges (BIRDs) on EEG?
This is a very challenging question, and the clinical importance of BIRDs, besides being associated with an increased frequency of seizures (Yoo et al., PMID 24535702 ), is unclear. I am a neurointensivist, and in general, I do not escalate therapy for intermittent BIRDs unless we identify concomita...
Under what circumstances would you choose the 1-month 1HP treatment over a 3-4 month regimen for latent TB?
I tend to favor the 1-month daily isoniazid–rifapentine regimen (1HP) in very specific clinical and programmatic contexts, rather than as a default option. Its main advantage is speed i.e. when there is a narrow window to complete latent TB treatment such as prior to imminent immunosuppression (e.g....
Do you maintain a strict platelet threshold of >50k when performing a lumbar puncture, or are there situations in which you feel comfortable with a lower threshold?
Our institution still uses 50k as a best practice guideline, though many of our proceduralists are comfortable performing the procedure with platelets slightly lower than 50k, and will have a risk/benefit discussion with the patient/team about the bleeding risk prior to proceeding; I myself would be...
