URGENT! Please circulate as widely as possible. It is crucial that every pulmonologist, every critical care doctor
and nurse, every hospital administrator, every public health official receive this information immediately.

This is our recommended approach to COVID-19 based on the best (and most recent) available literatureincluding the Shanghai Management Guideline for COVID. We should not re-invent the wheel, but learn
from others’ experience. This is a very fluid situation; therefore, I will be updating the guideline as new
information emerges. Please check on the EVMS website for updated versions of this protocol.

A few General thoughts:
1. We are all inhabitants of the same planet and we are all in this together. The medical
community needs to get off their “high pedestal” and act decisively and immediately; there is notime to lose.
2. It is likely that 40-80% of the population across the world will become infected with this virus. It
is therefore unrealistic for us to expect this will just go away. Our goal, therefore, should be to
reduce the mortality in those who are at greatest risk of dying. This requires those at risk to“socially” isolate themselves. Once they become infected, we should treat aggressively toprevent disease progression.
3. The course of the disease is quite predictable. Acute respiratory failure occurs on day 6-8 (dueto cytokine storm). In those patients requiring supplemental oxygen, we need to be very
aggressive to prevent progression to ARDS. Once ARDS develops, the mortality is high.
4. This is not your “typical” ARDS. Chest CT shows bilateral, discreet, irregular, multilobar infiltrates
and not the typical dependent air-space consolidation (“sponge lung”) characteristic of the usual
ARDS. Physiologically “COVID-19 ARDS” is different; our preliminary data suggests that lungwater (EVLWI) is only marginally increased. Furthermore, lung compliance is quite good yet
there is severe hypoxia (due to shunting). Cause unclear?? Microvascular thrombosis.
5. It is important to stress that there is no known drug/treatment that has been proven to improve
the outcome of COVID. This, however, does not mean we should adopt a nihilist approach.
Furthermore, it is likely that there will not be a single “magic bullet” to cure COVID-19. Rather,
we should be using multiple drugs/interventions that have synergistic and overlapping biologicalPage 1 of 9 | EVMS Critical Care COVID-19 Management Protocol 03-31-2020 | evms.edu/covidcareeffects, that are safe, cheap and could be made readily available. The impact on middle- andlow-income countries will be enormous; these countries will not be able to afford expensive
designer molecules.
6. Preliminary data suggests that chloroquine and hydroxychloroquine decrease the duration ofviral shedding. These agents (if available) could be used to mitigate/curtail the spread of thisvirus. They may be used in elderly patients with comorbidities at risk of progression and death.
7. Zinc (Zn++) inhibits viral RNA dependent RNA polymerase (replicase). Chloroquine andhydroxychloroquine are potent Zn ionophores that increase intracellular Zn concentrations.
8. Ascorbic acid has numerous proven biological properties (anti-inflammatory, anti-oxidant,immune enhancing, antiviral) that are likely to be of benefit in patients with COVID-19 disease.
Furthermore, it is important to stress that ascorbic acid has proven synergistic effects whencombined with corticosteroids. Therefore, steroids are recommended in patients with COVID-19and moderate to severe ARDS (see corticosteroids below). The benefit of ascorbic acid (withoutcorticosteroids) in patients with severe ARDS appears to be limited. While the optimal dose of
ascorbic acid is unknown, we suggest 3 g IV q 6 hourly. It should be noted that in the presence of
free iron (released from ferritin) ascorbic acid may potentially have pro-oxidant effects.
Therefore, the trends in CRP and ferritin need to be closely monitored; in those patients whoferritin AND CRP are increasing, reducing the dose to 1.5g q 6 hourly should be considered.
9. Very recent data suggests that in addition to being a potent anti-oxidant, melatonin may havedirect antiviral effects against COVID-19. In healthy people, melatonin levels plummet after theage of 40 years. This may partly explain the increased risk of death in patients with COVID-19
who are over the age of 40. Melatonin may therefore have a role in both the prevention andtreatment of COVID-19.
10. Vitamin D has important immune-enhancing effects. Much of the population, especially theelderly have sub-optimal vitamin D levels, particularly during the winter months. Low vitamin Dlevels have been shown to increase the risk of developing viral upper respiratory tract
infections. Therefore, prophylactic vitamin D should be considered especially in the elderly.
11. Quercetin is a plant phytochemical. Experimental and early clinical data suggests that thiscompound has broad antiviral properties (including against coronavirus) and acting at various
steps in the viral life cycle. Quercetin is a potent inhibitor of heat shock proteins (HSP 40 and 70)
which are required for viral assembly. This readily available and cheap plant-derived compound
may play a role in the prophylaxis of COVID-19 in high risk populations.

Prophylaxis
While there is very limited data (and none specific for COVID-19), the following “cocktail” may have arole in the prevention/mitigation of COVID-19 disease, especially amongst the most vulnerable citizens
in our community; i.e. those over the age of 60 years and those with medical comorbidities. While there
is no high level evidence that this cocktail is effective; it is cheap, safe and should be readily available. So
what is there to lose?

Vitamin C 500 mg BID
Zinc 75-100 mg/day (acetate or gluconate)
Quercetin 500-1000 mg/day
Melatonin (slow release): Begin with 0.3mg and increase as tolerated to 1-2 mg at night
Vitamin D3 5000 u/day

Mildly Symptomatic patients (on floor):

xxxxx
x

Vitamin C 500mg BID
Zinc 75-100 mg/day
Quercetin 500-1000 mg/day
Melatonin 6-12 mg at night(the optimal dose is unknown)
Vitamin D 5000u/day
Observe closely.
N/C 2L /min if required (max 6L/min; however, consider early t/f to ICU for escalation of care).
Avoid Nebulization and Respiratory treatments. Use MDI if required.
NO Bagging.
Avoid non-invasive ventilation
T/f EARLY to the ICU for increasing respiratory signs/symptoms.

Respiratory symptoms (SOB; hypoxia: admit to ICU):
1. Chloroquine 500mg PO BID for 7-10 days or hydroxychloroquine 400mg BID day 1 followed by200mg BID for 4 days.
2. Ascorbic acid (Vitamin C) 3g IV q 6 hourly until extubated and for at least 4 days up to 10 days
(see dosage adjustment below and caution with POC glucose testing).
3. Thiamine 200mg q 12 (PO or IV).
4. Azithromycin 500mg day 1 then 250mg for 4 days.
5. Melatonin 6-12 mg at night (the optimal dose is unknown).
6. Zinc 75-100 mg daily.
7. Atorvastatin 40-80 mg/day. Of theoretical but unproven benefit. Statins have been
demonstrated to reduce mortality in the hyper-inflammatory ARDS phenotype (which is similarto COVID-19).
8. Magnesium: 2 g stat IV. Keep Mg between 2.0 and 2.4 mmol/l. Prevent hypomagnesemia (whichincreases the cytokine storm and prolongs Qtc).
9. Broad-spectrum antibiotics only if superadded bacterial pneumonia is suspected based on
procalcitonin levels and resp. culture (no bronchoscopy).
Co-infection with other viruses appears to be uncommon, however a full respiratory viral panel
is still recommended. Superadded bacterial infection is reported to be uncommon (however,this may not be correct).

11. Early norepinephrine for hypotension. While the angiotenin II agonist Giapreza ™ has a limited
role in septic shock, this drug may uniquely be beneficial in patients with COVID-19(downregulates ACE-2).
12. DVT prophylaxis with enoxaparin 40mg/daily (heparin in AKI/CRF); additional role of ASA
unknown (see hypercoagulable state)
13. Optional: Tocilizumab (if available) may have a role in cytokine storm (specific IL-6 inhibitor).
14. Optional: Consider full anticoagulation with heparin in patients with rapidly increasing D-dimer
and/or those with severe “refractory” hypoxic respiratory failure (? due to pulmonary
microvascular thrombosis). The use of half-dose rTPA has also been suggested: 25mg of tPAover 2 hours followed by a 25mg tPA infusion administered over the subsequent 22 hours, witha dose not to exceed 0.9 mg/kg.
15. Escalation of respiratory support (steps)
x N/C 1-6 l/min
x High Flow up to 30 L/min
x Intubation … by Expert intubator; Rapid sequence. No Bagging; Full PPE. Crash/emergency
intubations should be avoided.
x Volume protective ventilation following ARDSnet table
x APRVx Prone positioning
x ?? ECMO < 60yrs and no severe commodities/organ failure.
There is widespread concern that using HFNC could increase the risk of viral transmission. Thereis however, no solid evidence to support this fear.
CPAP/BiPAP may be used in select patients, notably those with COPD exacerbation or heart
failure.
16. Consider plasma exchange for cytokine storm/HLH picture (see steroids below). The use of CVVH
filters that remove cytokines should also be considered.
17. Steroids:
This topic is controversial. However, the only study on the use of corticosteroids and COVID(from Wuhan) demonstrates a marked mortality reduction with methylprednisolone (60mgdaily)x During the early viral replicative stage, probably best to avoid.
x During the hyperimmune phase (day 6-8 onward) in patients with hypoxia/ARDS.
Hydrocortisone 50mg IV q 6 for 4 days is recommended (together with ascorbic acid) basedon features of ARDS and high CRP (lung injury is due to cytokine storm) .
x Patients may evolve into an HLH/cytokine vortex phase, marked by increasing ferrin, IL6 and worsening oxygenation. These patients may benefit from high dose
methylprednisolone. (dose ?? 200-500 mg q 12).

x In patients receiving IV vitamin C, the Accu-Chek™ POC glucose monitor will result in spuriously
high blood glucose values. Therefore a laboratory glucose is recommended to confirm the blood
glucose levels.
x Il-6 at baseline and ? every 3-4 days.
x Monitor QTc interval if using chloroquine/hydrochloroquine and azithromycin and monitor
Mg++
x No routine CT scans, follow CXR and chest ultrasound.
x Follow ECHO closely; Pts develop a severe cardiomyopathy.
