FIBEROPTIC LARYNGOSCOPE
Use of a Modified Endoscopy Face Mask for Flexible Laryngoscopy During the COVID-19 Pandemic
Dynamic
Symptomatic adaptable laryngoscopy (DFL) is a basic device in the armamentarium of an otolaryngologist. Be that as it may, amidst the COVID-19 pandemic, DFL speaks to a high-hazard system for patients and otolaryngologists because of the danger of aerosolization. In situations where DFL is needed, in patients with COVID-19 energy or obscure COVID-19 status, we depict the utilization of a changed endoscopy face veil as an aide to individual security gear to lessen word related transmission of COVID-19 while performing DFL. Our changed endoscopy veil gives an extra hindrance against the transmission of airborne microbes. The changed endoscopy face veil may likewise fill in as a valuable device for otolaryngologists as they re-visitation performing more vaporized creating methods in the outpatient setting.
The 2019 novel Covid illness (COVID-19), proclaimed a worldwide pandemic on March 11, 2020, by the World Health Organization, presents remarkable difficulties to medical care frameworks around the globe, influencing patients and medical services workers.1 Among the clinical network, otolaryngologists are especially at high danger of word related presentation to COVID-19, given the idea of head and neck assessments, where SARS-CoV-2 is pervasive in high concentrations,2 and because of generally performed vaporized creating procedures.3 Diagnostic adaptable laryngoscopy (DFL) is a basic instrument in the armamentarium of an otolaryngologist that guides in the representation of the nasal depression, larynx, and pharynx. Nonetheless, amidst the COVID-19 pandemic, DFL speaks to a high-hazard technique for patients and otolaryngologists, held for basic situations where discoveries may change the board. Moreover, as the pandemic advances and clinical offices continue nonemergent administrations, there is a need to decide how to perform DFL securely.
In situations where DFL is needed, in patients with COVID-19 inspiration or obscure COVID-19 status, we portray the utilization of an adjusted endoscopy face veil as an assistant to individual security hardware (PPE) to diminish word related transmission of COVID-19 while performing DFL

STRATEGIES
Supplies and Equipment
To recreate outpatient DFL, an aviation route reenactment puppet (Laerdal SimMan Manikin; Laerdal Inc) was situated upstanding on a center assessment seat. A grown-up endoscopy face cover (VBM Medical), intended to permit fiberoptic nasotracheal intubation through a 5-mm port with synchronous ventilation,4 was changed to empower the section of a standard adaptable laryngoscope by forming a 3-mm cut with a surgical tool. The endoscopy face veil was then made sure about on the puppet through a face cover saddle (Rusch Medical) and joined to a snare ring. A warmth and dampness exchanger with a bacterial and viral channel (McKesson Corporation) was appended to the sub-par measure of the face veil (Figures 1-3).
Figure 1. Hardware is needed for the adjusted endoscopy face veil. From left to right: grown-up endoscopy face veil with 5-mm endoscopy port, snare ring, warmth and dampness exchanger with the bacterial and viral channel, face cover saddle, and No. 10 or 15 surgical tools (not envisioned).
Figure 2. Formation of a 3-mm cut in the focal silicone film of the endoscopy face veil with a No. 10 surgical blades to permit entry of the adaptable fiberoptic laryngoscope.
Figure 3. In-office arrangement for adaptable fiberoptic laryngoscopy, with an altered endoscopy face cover, made sure about by an outfit. (B) Flexible fiberoptic laryngoscopy at the degree of the vocal folds, with an altered endoscopy face cover and a warmth and dampness exchanger with the bacterial and viral channel.
A 3.5-mm adaptable distal chip laryngoscope (Pentax Medical) was effectively gone through its 5-mm port. With the 5-mm port stopped, the degree was likewise gone through the adjusted 3-mm cut with insignificant obstruction, accomplishing a more tight seal. The extension had the option to be moved without trouble through the cover and come to the subglottis effortlessly, with just 5 cm of dead space between the face veil and the patient.

Otolaryngologists are uncommonly powerless to the iatrogenic transmission of COVID-19, given the high popular heap of SARS-CoV-2 in the upper aviation route of contaminated patients. Otolaryngologists are presented to breathed out microorganisms during a normal assessment of the nasal sections, oral hole, and oropharynx and especially more during endoscopy and other airborne creating techniques were choking, hacking, and sniffling are regular occasions. Aerosolized COVID-19 particles may stay airborne for as long as 3 hours and may make due on surfaces for much longer.5 Recommendations have been distributed in the otolaryngology writing upholding that adaptable laryngoscopy is performed just (1) in basic cases and when discoveries may immediately affect tolerant administration, (2) in light of pre-methodology COVID-19 testing, (3) with the utilization of a fueled air-cleaning respirator or N95 cover notwithstanding PPE by the supplier, and (4) with the utilization of a careful veil by the patient.6,7 Awareness of these practices is the way to decrease aerosolization dangers to medical care laborers. If adaptable laryngoscopy is required—regardless of whether in the setting of patients with known or obscure COVID-19 status or for those at high danger who test negative on polymerase chain response (PCR), given the huge bogus negative pace of current converse record PCR assay8 for COVID-19—we advocate the utilization of the changed endoscopy veil depicted in this correspondence.
Endoscopy covers are anything but difficult to utilize and broadly accessible in focuses with endoscopy suites. The blend of the adjusted endoscopy veil and warmth and dampness exchanger with the viral channel, while maybe not giving a 100% impermeable seal, considers an extra hindrance for transmission of airborne microorganisms and a valuable subordinate to PPE. The altered endoscopy face veil additionally takes into account adaptable laryngoscopy to be acted in patients who require ventilation, as in intubated patients who are COVID-19 positive, while limiting aerosolization of airborne microorganisms. Extra techniques that relieve bead transmission of the infection—including the utilization of sedative gels, hand cleanliness, and laryngoscope sterilization—should be utilized as recently depicted in the literature.6,7 In a new article, Workman et al contemplated the aerosolization of particles from controlled instrumentation during nasal endoscopy in a dead body model utilizing a careful cover and an adjusted careful "VENT veil," altered with the expansion of an interior and outer careful glove through which the endoscope passes. The gathering indicated that vaporizers were diminished by both the standard careful cover and the VENT veil in a recreated wheezing event.9 We accept that our adjusted endoscopy face cover gives an improved boundary to the transmission of mist concentrates since a more tight seal is accomplished, in this manner diminishing potential airborne departure.
End
Adaptable laryngoscopy is a fundamental technique in otolaryngology that represents a high word related danger of transmission of COVID-19. Current suggestions incorporate restricting DFL to basic cases. If DFL is required—regardless of whether in patients with COVID-19, with obscure COVID-19 status, or at high danger who test negative on PCR—we advocate the utilization of our changed endoscopy face veil close by PPE to fill in as an extra boundary against viral transmission. The altered endoscopy face cover may likewise fill in as a helpful device for otolaryngologists as they re-visitation performing more vaporized producing strategies in the outpatient setting.
