Episode 44: Physical therapy with Heidi Engel

A look at rehabilitation and mobility in the critically ill, from the perspective of our skilled therapists—with Heidi Engel, PT, DPT of UC San Francisco, long-term provider of acute care therapy, researcher in ICU rehabilitation, and founding member of the SCCM’s ICU Liberation program.

Takeaway lessons

  1. Tolerance of pressure support ventilation is often a good marker that a patient is ready to start meaningful PT. Before that, the harm may exceed the benefit, unless there’s a specific reason why activity may help move them along, such as attenuating delirium and agitation and improving tolerance of the ET tube.
  2. The most common complaints and stressors of ICU patients are: feeling thirsty, feeling traumatized and afraid, the inability to communicate, and feeling “air hungry” due to the strange mechanics of mechanical ventilation and other respiratory modalities.
  3. In many cases, rehab will require convincing patients to get over an initial hump. Breathing, strength, and discomfort may initially be a challenge but will improve with activity.
  4. You may need to choose priorities: do you want to push vent liberation or mobility today?
  5. Bring the light during daytime hours to improve the circadian rhythm, but direct fluorescent lights are harsh and can encourage closed eyes. Natural, indirect light is better.
  6. Although PT and OT have complementary roles, they will sometimes try to see patients together, which can have downsides by underemphasizing the unique aspects of each role, reducing total rehab time, and relegating one skilled therapist to acting as merely a set of hands.
  7. The presence of any sedation, even “gentle” agents like precedex, creates an obstacle to effective PT.
  8. Getting patients up to a chair helps with agorophobia by changing their perspective from their tiny bed-shaped home.
  9. Heidi’s rehab process
    1. Check the RASS and CAM-ICU scores
    1. Explain to patient the importance of the endotracheal tube and not touching it. Bring all equipment to the side of the bed with the ventilator.
    2. Perform some gastroc/hamstring stretching to initiate mobility and help wake the patient up
    3. Ask them to follow commands, such as: push! Can they follow? Do the vent and vitals remain okay?
    4. Sit them up at edge of bed, arrange equipment. Observe head control, trunk control, breathing, vitals, orthostasis, etc.
    5. bring a big mobility device, see if they can stand.
    6. While they’re up, use the opportunity to clean the linen, wash their face, comb their hair, clean their posterior.
  10. COVID is making it harder, often just for practical reasons: PPE limiting mobility, noise from filters and masks, families not present, weird autonomic and orthostatic issues… all far more time consuming. However, they do get better and many times do very well, sometimes even recovering faster than similar non-COVID patients. Omicron has not been as bad.
  11. Dedicated therapy teams for the ICU add cost, but cost analyses have shown the benefit (in terms of reducing length of stay and other expenses) to actually result in net cost savings.
  12. In-bed, non-weight-bearing activities such as passive range of movement exercise is perhaps better than nothing, but is nowhere near as useful as weightbearing activity out of bed, and has not shown the same clinical benefits in the literature. Every day of out-of-bed activity may pay back several fewer days of rehab down the road.

Lightning rounds #13: What’s the deal with nurses?

Brandon and Bryan reflect on the qualities that define good and bad ICU nurses, the challenges they face, and how APPs and physicians can enable them to be their best.

TIRBO #4: Hope

Why an assumption in your training should be to call for assistance, but expect it will never arrive. Plan to manage problems yourself. Let help surprise you—otherwise hope becomes your plan.

Episode 43: Resuscitative TEE with Felipe Teran

The hows, whys, logistics, and applications of focused, bedside transesophageal echocardiography performed by critical care and EM providers, with Felipe Teran, assistant professor of emergency medicine at Weill Cornell and director of the Resuscitative TEE Project.

Takeaway lessons

  1. As a rule, resuscitative TEE is performed in patients with a secured airway.
  2. TEE views are not unlike TTE views, just at a different angle (often backwards/upside down down). The technical skills are very similar, and skilled TTE users will find the learning curve short. There are actually fewer probe manipulations (in and out, left and right, and Omniplane rotation, along with some less-used ones like flexion/extension).
  3. The same questions you’d typically ask with TTE can be asked with TEE: is there tamponade? is there cardiogenic shock? is there RV failure? is there hypovolemia? These can be answered even in patients with technically-difficult surface windows.
  4. Some questions hard to answer with TTE can be answered with TEE, such as obtaining reliable RV inflow-outflow views and reliable valve assessments.
  5. Some new questions can be answered with TEE alone: is there aortic dissection? are catheters and wires (ECMO, Impella, pacing wires, etc) optimally placed?
  6. TEE has specific applications in cardiac arrest: are chest compressions optimally positioned on the chest? What is the rhythm? It provides monitoring much more continuous than intermittent TTEs, since it can be left in place.
  7. In an ideal world, resuscitative TEE would be handled very much like TTE, and performed in a similar way—not restricted to some small group of “superusers” or for very rare cases.
  8. When implemented by trained users in appropriately-selected cases (e.g. in shock with inadequate transthoracic windows), it impacts care virtually 100% of the time.

TIRBO #3: Weaning vs Titration

When do interventions need to be “weaned”? Stop using this word when you don’t mean it! Titrate, target to effect, but only wean when there is a physiologic dependence.

Lightning rounds #12: Co-managing patients in a surgical ICU

Brandon and Bryan talk about the practicalities of communication, collaboration, and compromise in a surgical ICU, when the surgical and critical care teams are both involved, one is the “primary” team on paper, but everyone needs to be heard.

Episode 42: Clinical pharmacists with Laura Means Ebbitt

An overview of the role and contributions of a clinical pharmacist in the ICU, with Laura Means Ebbitt of the University of Kentucky, a clinical pharmacist specializing in colorectal/ENT surgery and critical care.

Takeaway lessons

  1. A clinical pharmacist is a “knowledge pharmacist,” dispensing advice rather than medications. They round with the team to review meds and answer questions about routes, interactions, etc, follow up on patient education and post-discharge coordination, assist with medications during cardiac arrests and other emergencies, and provide other clinically-oriented guidance and oversight. Most have completed post-graduate residency programs.
  2. Clinical pharmacists generally have an important role for antibiotic regimen selection, monitoring, and stewardship.
  3. They consider cost in a way that providers rarely do.
  4. They provide patient education that we typically defer or omit.
  5. They’re great at catching deviations in good ICU practices, such as missing DVT or stress ulcer prophylaxis, managing and reconciling home medications, and coordinating nutrition needs (particularly with TPN).
