The document discusses changes to airway management in the post-COVID pandemic era. It notes that COVID-19 often leads to respiratory complications and sequelae. Some key points discussed include: increased use of protective equipment and infection control measures during airway procedures; adoption of alternative techniques like HFNC and NIV; training on specialized post-COVID airway management protocols; and monitoring patients for long-term effects like pulmonary fibrosis using tests like CT scans and pulmonary function tests. The challenges of potential increased airway injuries and need for multidisciplinary care are also addressed.

11. A spectrum of pulmonary manifestations, ranging from
1. dyspnea (with or without chronic oxygen dependence)
2. difficult ventilator weaning
3. fibrotic lung damage.
4. The need for supplemental oxygen due to persistent hypoxemia, or new
requirement for continuous positive airway pressure or other breathing
support
12. Viral-dependent mechanisms (including invasion of alveolar
epithelial and endothelial cells by SARS-CoV-2)
viral-independent mechanisms (such as immunological damage,
including perivascular inflammation) contribute to the breakdown
of the endothelial–epithelial barrier with invasion of monocytes
and neutrophils and extravasation of a protein-rich exudate into
the alveolar space, consistent with other forms of ARDS.
Pulmonary vascular microthrombosis and macrothrombosis
have been observed in 20–30% of patients with COVID-19
PATHOLOGY AND PATHOPHYSIOLOGY
15. LARYNGOTRACHEAL STENOSIS
TUBE SIZE- Use of larger than
normal tubes.
CUFF PRESSURE-
maintenance of excessively high
cuff pressure and delay in
tracheotomy performance . Cuff
pressure of endotracheal tube
above the capillary perfusion
pressure of tracheal mucosa
ranging from 20 to 30 mmHg
leads to mucosal ischemia and
damage.
INSTRUMENTATION -Prolonged
mechanical ventilation , using
high ventilatory pressures, and
consequent high tube cuff
pressure
POSITION-pronation cycles
used in intubated patients with
COVID-19 could have caused
an increase in airway lesions.
16. Illustration by Smart-Servier Medical Art
Persistent interstitial lung changes
Most frequent sequele.
Survivors from severe covid19 that required
high-flux nasal cannula (HFNC), non-invasive
ventilation (NIV) or intubation and
mechanical ventilation are more prone.
17. Pulmonary Fibrosis
PF disease is characterized by
scarring of the lungs.
Excessive deposition of
extracellular matrix molecules,
such as collagen, laminin, and
fibronectin, in the parenchymal
lung tissue
thickened alveolar walls, which
hinders gas exchange and
contributes to decreased and/or
declining lung function, dyspnea,
fatigue, and exercise intolerance.
18. ● The higher mortality rate of our ECMO-treated COVID-19 patients admitted after July 1, 2020, was
unexpected.
● strong and dysregulated spontaneous respiratory efforts, associated with wide transpulmonary pressure
swings might heighten the risk of harmful “self-inflicted lung injury” on HFNO or NIV, with more
frequent fibrotic evolution of COVID-19 pneumonia
20. Pulmonary function tests
● Pulmonary function tests have always been valuable in assessing
pulmonary diseases and respiratory function.
● MERS and SARS has shown that pulmonary function testing is a
valuable tool to assess for lung damage after recovery.
21. AIRWAY ULTRASOUND
● Airway ultrasound has gained significant
attention in the post COVID era.
● Useful in assessing respiratory
complications, airway management .
● Helpful in diagnosis of airway
stenosis,like airway stenosis , and vocal
cord dysfunction .
● Helpful regarding intubation, extubation
and management of airway issues.
25. REHABILITATION
● Low-intensity aerobic exercises followed by the introduction
of strengthening exercises and formal occupational therapy
and psychology evaluation.
● The European Respiratory Society and American Thoracic
Society interim guidance recommended formal assessment
6–8 weeks after acute infection,
● a comprehensive pulmonary rehabilitation programs for
patients with new or persistent respiratory symptoms in
addition to oxygen requirements, persistent radiological
abnormalities, or pulmonary function tests abnormalities.
Telerehabilitation and home-based programs are increasingly
used.

Labarca et al. conducted a case–control study among patients with acute
respiratory distress syndrome (ARDS) secondary to COVID-19 and mild or
moderate disease, showing that, in surviving patients, the prevalence of
undiagnosed OSA was statistically significant compared to patients with mild
or moderate disease. After adjusting for other confounders, OSA was
independently associated with ARDS. Moreover, undiagnosed OSA
presented more pulmonary sequelae in the medium term, in addition to being
associated with variables such as male gender, ARDS, and total days on
invasive mechanical ventilation

ETT-. It completely seal the trachea and provides better
protection against aerosol liberation and lowers infection risk for
healthcare providers .
MUSCLE RELAXANT- Use of more rapid inducing agents like
succinylcholine and rocuronium .

HFNC
It became more available .
The WHO advises that HFNO should be used
for selected adult patients with hypoxaemic
respiratory failure and that HFNO can reduce
the need for intubation.
Use in paediatric population has increased.
Apnoeic oxygenation time has really increased
.
HFNO has been used to prolong the apnoea
phase during tracheal intubation and to reduce
intubation rates in acute respiratory failure

SIZE-The fear of contamination of health care workers during invasive and aerosol generating manoeuvres such as tracheostomy often
Availabity and cost effectiveness of disposable equipments should be balanced with the environmental consideration
ETT-Over the past years, prehospital airway management for paramedics has moved away from endotracheal intubation (ETI) towards supraglottic airway devices (SAD), skill acquisition and skill retention for ETI have proven difficult and there is evidence that SAD are non-inferior to ETI in OHCA. In the context of COVID-19, however, ETI has made a comeback
