Abstract

Post-extubation dysphagia (PED) has been studied in depth in a variety of populations including elective heart surgeries, trauma, critical illness, traumatic brain injury, and those requiring mechanical ventilation, but has not been researched in the overdose population (OD). This study aims to research factors of PED in the OD population. A retrospective study was conducted and found 24 participants who fit the inclusionary requirements. Correlation statistics were run between age and duration of intubation, age or duration of intubation and gender, and between intubation duration, age, and scores on Penetration-Aspiration Scale (P/A) (thin by cup and thin by straw). The preliminary results found that there were no significant correlations between the factors listed above. The authors of the study conclude that the one factor linking all of the participants is OD of drugs. Due to the overlaid function of the respiratory and swallowing systems; copious intake of drugs impacting the respiratory system will result in the swallowing mechanism being impacted. As this study was the first of its kind for this population, further research will need to be conducted to explore PED in the OD population.
