Povidone Iodine (PVP-I) Oro-Nasal Spray: An Effective Shield for COVID-19 Protection for Health Care Worker (HCW), for all

My Experience with PVP-I in COVID-19 Era

Like lot of doctors and scientists of different part of the world, I have firm belief on PVP-I, which is a time tested, trusted virucidal agent. More than 50 dedicated doctors (including me) and other HCW of my network voluntarily use this oro-nasal spray for same purpose for the last 5-9 months.

I personally use it by myself in my private practice, in all of my surgery, all of the OPD procedures. Irrespective of COVID-19 status, either RT-PCR test positive or negative. All of my staffs are trained enough to prepare my patients as well as themselves with PVP-I either by gargling/spraying their throat and/or spraying in nose prior to visit me. Since May 2020 I have attended more than 7000 patient in OPD and emergency, performed 501 endoscopy of larynx and nose (FOL, DNE) and 203 surgeries, including tracheostomy, mastoidectomy, endoscopic sinus surgery, skull base surgery, laryngeal biopsy, tonsillectomy, septoplasty etc. These are airway surgeries and moreover, most of them are aerosol generating procedures) [12, 13, 14].

In my private practice I always examined thoroughly all the area of my concern (i.e. oral cavity, nose and ear) without hesitation, without compromising the quality of proper examination. My patients were always satisfied and compliance was extraordinarily good, because oral cavity and nose examinations are avoided mostly in COVID-19 era.

Among all of my OPD patients more than 51 person diagnosed COVID-19 positive later, as I advised them to do RT-PCR test following physical examination and they were tested positive.

2 of my patients of emergency tracheostomy diagnosed COVID-19 positive 1 day later. Three nearby patients as well as two attendants were infected by them within one day of hospital stay (in non COVID unit). Here, I should mention that, Tracheostomy is one of the most aerosol generating procedure, where chance of COVID-19 transmissibility is more than any other surgery. Interestingly, among twelve different health care providers, including doctors, nurses and OT staffs, directly involved and exposed in these two surgeries, none of them were infected. Importantly, ‘POLIDON’ approach was followed in both the procedures [12, 14].

For the previously mentioned clinical trial purpose, I had to go in close contact with COVID-19 patients for 31 days in the COVID-19 dedicated unit of Dhaka Medical College Hospital within 45 days. During nasal irrigation or spraying, patients cough on me or my team members several times. But for the grace of almighty Allah (God), me with all of my team members are free from COVID-19 still now.

HCWs of multiple hospitals or institutes of different parts of the world are using PVP-I in different form for protection from SARS-CoV-2. In Bangladesh authorities or individual doctors of Dhaka Medical College Hospital, Bangabandhu Sheikh Mujib Medical University, National Institute of ENT, Bangladesh ENT Hospital, ENT and Head Neck Cancer Hospital and most of the ENT, dental or maxillofacial related health care professionals adopted this policies in different extent.

Adjunct to PPE, mask, hand sanitizer, my strong belief in this regard—use of PVP-I oro-nasal spray gives me an extra protective layer over nasal, nasopharyngeal, oral and oropharyngeal mucosa. Moreover, when my patient gargles with PVP-I or spray PVP-I solution in oral cavity, throat and nose all the SARS- CoV-2 of these areas are destroyed and absent, at least for certain period of time. It reduces the possibility of SARS-CoV-2 transmission from patient, which made me more courageous and confident. Figures ​Figures6,6, ​,7,7, ​,8,8, ​,99 and ​and1010
