COVID - 19:Physiotherapy in the ICU

Physiotherapy in the FMC ICU: Some Context
• ARDS is not a new phenomenon in ICU, it can occur from many different sources (e.g. sepsis, trauma) [1] • However, COVID-19 poses unique challenges related to anticipated number
of ARDS patients and transmissibility • Currently ~30 ICU beds, preparing for surge capacity of ~150 beds • Modelling suggests probable scenario of 232 AB COVID-19 cases
needing ICU care in late May-June [2]• Patients who survive ARDS at high risk for impaired physical
function, PTSD and depression [3]• Major focus on early progressive mobility to improve patient
outcomes [4]

Case Study: Initial Stage
• Patient in their 40s, admitted with severe respiratory failure (ARDS) secondary to COVID-19
• Total of 22 days spent in ICU • During initial stage of ICU stay, patient was consistently:
• Intubated and fully dependent on ventilator • Sedated • Chemically paralyzed on neuromuscular blockers
• Proned 5 times to improve ventilation (16 hours prone/8 hours supine)
• Developed an acute kidney injury, requiring continuous dialysis

PT Involvement: Initial Stage ● Evidence for chest PT in ARDS sparse
● Ineffective cough (due to paralytics) may benefit from PT involvement to facilitate secretion clearance
● Primarily an issue of inflammation and pulmonary edema rather than secretion production
● Main role is related to preventing secondary complications ● Maintaining ROM ● Positioning ● Monitoring for appropriateness for mobilization
● Heavily reliant on input and collaboration with interprofessional team (RNs, RTs, MDs) at this stage
5
Case Study: Gradual Improvements
• After approximately 10 days intubated, ventilated, sedated and chemically paralyzed, patient began gradually showing signs of improvement, including: • No longer requiring proning • Decreased O2 requirements, improvement seen on blood gasses and chest
x-rays • Improved tolerance for neuromuscular blockade and sedation weaning • Improved global organ function, no longer requiring continuous dialysis
• Not linear, days of slow improvement with episodes of decline

PT Involvement: Initiating Early Mobility
• Mobility is the primary treatment approach to address deconditioning and optimize respiratory status
• Monitoring patient status from beginning allowed for identification of improvements to help make informed decision about mobility
• Decision to initiate early mobility required extensive discussion with team to confirm that we were pursuing the same goals
• Consistently evaluating the risks vs. benefits of pushing patient
7
PT Involvement: Mobility ProgressionFirst session: positioned patient upright in bed
• Done to assess tolerance for upright positioning • Increased respiratory rate, brief desaturation
Second session: positioned in bed-chair, sat forward to dangle with 2 person max assist
• Improved tolerance, still too sedated to progress
Third session: transferred to sitting at edge of bed with 2 person assist • Tolerated approximately 10 minute dangle, helped make a case for extubation
Fourth session (after extubation): patient stood, transferred to/from chair with 1-2 person assist
• Tolerated well!

Guiding Principles Constantly evaluate risks vs. benefits
• ARDS patients are very fragile; however, not mobilizing has risks too!
Be more conservative • In an effort to conserve PPE and limit contact unless absolutely necessary
Collaborate, collaborate, collaborate! • Share assessment findings, work with other HCPs to plan care
Be flexible • May involve completing tasks outside of typical role to optimize efficiency
Caseload management: Don’t forget about non-COVID patients• Plan to see COVID-positive patients at the end of the day
Focus on the patient, not just the COVID status • While considerations around COVID are pertinent, important to maintain a high standard of care to
optimize outcomes for these patients
