The safety of healthcare workers is a priority for public health protection. This is the basic principle we teach apprentices in paramedics, nursing and medicine. Only a safe specialist can help those in need. The COVID-19 pandemic suddenly appeared and resulted in more attention being paid to the possibility of droplet transmission. Until now, medical staff only paid attention to blood-borne and contact infections, and the air-borne route was underestimated. Current painful experiences raised by SARS-CoV-2 require us to verify the current procedures performance and introduce the principles of safe for the staff to perform endotracheal intubation with appropriate protection measures. Healthcare workers should use barrier surgical caps, goggles or face shield, FFP3 mask, protective gowns, double gloves and utilize proper hand washing technique. Additionally, some protective barriers might be used to minimize aerosol dispersion during endotracheal intubation.

Bezpieczeństwo pracowników służby zdrowia jest priorytetem publicznego systemu ochrony zdrowia. To jest podstawowa zasada, której uczymy praktykantów w zakresie ratownictwa medycznego, pielęgniarstwa i medycyny. Tylko odpowiednio zabezpieczony specjalista może pomóc potrzebującym. Pandemia COVID-19 pojawiła się nagle, w wyniku czego zwrócono większą uwagę na możliwość przenoszenia zakażeń drogą kropelkową. Aż do chwili obecnej personel medyczny zwracał uwagę tylko na infekcje krwiopochodne i kontaktowe, a droga powietrzna była niedoceniana. Obecne bolesne doświadczenia związane z SARS-CoV-2 wymagają od nas weryfikacji aktualnych procedur i wprowadzenia zasad bezpiecznego dla personelu wykonywania intubacji dotchawiczej przy zachowaniu odpowiednich środków ochronnych. Pracownicy służby zdrowia powinni używać ochronnych czepków chirurgicznych, okularów ochronnych lub osłony twarzy, maski FFP3, fartuchów ochronnych, podwójnych rękawic i stosować odpowiednią technikę mycia rąk. Dodatkowo w celu zminimalizowania ryzyka można zastosować dodatkowe bariery ochronne zapobiegające dyspersji aerozolu podczas intubacji dotchawiczej.

This study reports the results of field research into variability of the scavenging coefficient (Λ) of suspended dust comprising particles with aerodynamic diameters less than 10 mm. Registration of PM10 over 7 years in conditions of the occurrence of rainfall (convective light showers, large-scale precipitation and storms) was undertaken in an undeveloped rural area. The analysis involved 806 observations taken at constant time intervals of 0.5 hour. The measurements of the concentration of PM10 were performed by means of a reference method accompanied by concurrent registration of basic meteorological parameters. It was found that, for PM10, the scavenging efficiency is considerably influenced by rainfall intensity R and the type of precipitation. In the case of convective precipitation, data on Λ are only partially related to “classical approach” of rain scavenging. Within the range of comparable values of rainfall intensity, the type of wet deposition (except for storms) does not influence the effectiveness of scavenging PM10 from the ground-level zone. The large number of observations conducted in real-time conditions yielded a proposal of simple regression model, which can be deemed suitable for the description of variability Λ (DPM10), but only to a limited extent for large-scale precipitation. The collected results can be applied in air pollution dispersion models and deposition and were found to be generally representative for areas with similar climatic characteristics.
