Guidelines for otorhinolaryngologists and head neck surgeons in coronavirus disease 2019 pandemic

ABSTRACT

Background: Coronavirus disease 2019 was first identified in Wuhan, the capital of China's Hubei province, in December 2019. India has witnessed a massive surge of coronavirus cases. Main text This study details the measures to be taken by the clinicians involved in doing otorhinolaryngology and head neck surgery in light of the recent coronavirus disease 2019 pandemic. All COVID-positive patients should be admitted in a separate COVID ward, and patients should be screened for COVID-19 before admission. Only emergent ENT surgeries should be done in an operating room having a negative pressure environment with high-frequency air changes, and all staff must wear personal protective equipment. The anesthetist intubates the patient while the surgical team waits outside the operation theater post-intubation for 21 min. For otology surgery, double draping of the microscope should be done;for rhinology surgery, concept of negative-pressure otolaryngology viral isolation drape (NOVID) system should be used. Smoke evacuation system is set up inside the tent to evacuate any smoke produced during the surgery. Tracheostomy should be done at least after 10 days of mechanical ventilation with cuffed, non-fenestrated tracheal tube inserted through the tracheal window, and a separate closed suction system is used for suctioning. After the surgery is completed, disposal of PPE kit needs to be done according to local guidelines. After completion of the surgery, the full anesthesia unit should be disinfected for 2 h with 12 % hydrogen peroxide. Chlorine-containing disinfectant (2000 mg/L) is used to clean the floor of the operation theater and clean all the reusable medical equipment. Ultra-low volume 20 to 30 mL/m of 3% hydrogen peroxide is used to fumigate the OT for 2 h. Conclusions: COVID-19 is a newly discovered infectious disease. Measures need to be taken to prevent transmission and attain a plateau and decline in the disease. Otorhinolaryngologists and head neck surgeons are at high risk of this infection. This review summarizes the protocol for otorhinolaryngologists and head neck surgeons caring for patients in this current scenario. Protocols need to be strictly followed to prevent the spread of this disease.
