Viral Load in Upper Respiratory Tracts

Viral loads seems to be higher soon after the symptom onset, with higher viral loads detected in the nose than in the throat. The results suggest a potential transmission potential by asymptomatic or minimally symptomatic patients, as the viral load in the asymptomatic patient was similar to the symptomatic ones.   These data come from […]

Guidelines: Tracheotomy

Canadian Society of Otolaryngology-Head and Neck Surgery strongly advise against performing a tracheotomy in still infectious COVID-19 patients. In positive patients, requests for tracheotomy should generally not be considered regardless of duration of endotracheal intubation.  In emergency tracheotomy with unknown COVID-19 status:  Manage patient as if COVID-19 positive.  Intubation rather than tracheotomy is highly preferable. […]

Anosmia as a Marker of Infection

Anosmia/hyposmia and ageusia are present in a majority of Covid-19 patients (5, 6) These symptoms are significantly more frequent in COVID-19 patients than influenza patients(1) and influenza-like patients. (6) They usually have an acute onset and commonly present as an initial manifestation. (1,5) Most patients reported complete or partial recovery of smell and taste. (1,6) […]

What Is the Efficacy of Masks in Preventing Transmission?

Aerosol is a potential mode of transmission from asymptomatic individuals. Surgical masks could reduce the emission of virus particles into the environment in droplets and aerosols. Therefore, they have the potential to reduce onward transmission if worn by symptomatic individuals. Only a minority (35%) of infected participants shed detectable virus in droplets or aerosols, and […]

Special Precautions in Dental Emergency

Patient screening is critical: epidemiological risk factors and clinical symptoms (fever and respiratory tract symptoms) should be asked. Measuring the temperature with contact-free forehead thermometer is recommended. Standard protective measures (universal precautions) are not effective enough to prevent the spread of COVID-19. Special precautionary measures should also be taken. Level 2 PPE is required for […]

Special Precautions in Oral Surgery

Pre-procedural mouth rinse is an effective method to reduce the viral loads in oral fluid. Oxidative agents such as hydrogen peroxide are more effective than chlorhexidine. Panoramic radiography is an appropriate alternative during the outbreak, since intraoral x-ray can stimulate saliva secretion and coughing. Absorbable suture is preferred over non-absorbable For simple extraction, treat the […]

PPE requirement for Aerosol Generating Medical Procedures

The recommendations for Minimum Personal Protective Equipment (PPE) depend on several factors: Procedure-related factors: AGMP (Aerosol Generating Medical Procedure) or non-AGMP Patient-related factors: symptomatic or asymptomatic COVID-19 test results: COVID positive, negative or unknown Asymptomatic patients undergoing AGMP should be screened for COVID-19 before the procedure, since the PAPR [Powered Air-Purifying Respirator] is required in […]

Prevention of Nosocomial Infections Among Staff

Health-care workers and other patients in ENT departments are especially at high risk of contracting the Covid-19, since most of the procedures involve direct contact with patients’ upper respiratory tract mucosa and can potentially induce patients to sneeze or cough.  Nose and throat examinations have the highest risk of contamination and transmission among ENT examinations, […]
