On April 7, 2020, theFOAM Think Tank (www.dasfoam.org) published a highly interesting article entitled: "Reanimation and Covid-19: The Renaissance of the Laryngeal Tube?" online.
The article deals with the risk of SARS CoV-2 infection during cardiopulmonary resuscitation of patients suspected of having Covid-19.
The study has published in July 2020 in the journal "Resuscitation" [Ott M, Milazzo A, Liebau S, Jaki C, Schilling T, Krohn A, Heymer J, Exploration of strategies to reduce aerosol-spread during chest compressions: A simulation and cadaver model, Resuscitation (2020), doi: https://doi.org/10.1016/j.resuscitation.2020.05.012].
The authors of this paper have considered the risk for the personnel involved, especially in the management of the airway through patient aerosol, and which aids could minimize the risk of infection. The examination was carried out using a modified resuscitation manikin. The result of the examination shows that the use of the LTS-D in combination with a breathing system filter can best minimise the risk of infection. Compared with the LTS-D were chest compressions with-out ventilation, the use of a mouth and nose protector or alternatively an oxygen mask on the patient, bag-mask ventilation with a breathing system filter, a laryngeal mask and endotracheal intubation by direct laryngoscopy. The authors were able to confirm the results of the study in a further study on human cadavers. The attached illustrations impressively show the different aerosol distribution.
