Oral care and photobiomodulation protocol for the prevention of traumatic injuries and lip necrosis in critically ill patients with COVID-19: an observational study.

Abstract

It is well reported that severe cases of COVID-19 frequently need critical care in the ICU to manage respiratory complications, often requiring orotracheal intubation (OTI). Due to complex systemic conditions, the patient may remain intubated for a long period of time and be placed in prone position. This positioning and the pressure of the intubation device on the lips may lead to the development of traumatic injuries. Oral care and the use of photobiomodulation (PBM) can be successfully implemented to promote oral mucosa healing and prevent soft tissue necrosis. We describe the outcomes of the management protocol that was routinely used by the ICU oral medicine team, leading to the implementation of a preventive protocol for the OTI-related oral injuries. We retrospectively analyzed the records of 472 patients with COVID-19 in the ICU from May 2020 to February 2021. 60/472 patients developed traumatic injuries and were managed with the oral care protocol and PBM, to prevent the progress to lip necrosis. When appropriated, in addition to oral care and PBM, other measures were taken to prevent further local trauma (lip hydration, changes in tube fixation). The proposed oral care protocol associated with PBM successfully prevented the progress of traumatic lesions, ulceration, necrosis, and loss of tissue associated with IOT. The quality of life of patients in the ICU and after their recovery was preserved.
