Purpose
Analyse the evolution and outcomes of COVID-19 tracheostomised patients. Clarify if this cohort presents an increased risk of haemorrhagic complications and verify the correlation between some risk factors with increased mortality.
Methods
A retrospective single-centre observational study of a prospective cohort of all COVID-19 patients admitted to our centre between March and April 2020. A control group was obtained from a historical cohort of patients who required tracheostomy due to prolonged invasive mechanical ventilation (IMV) before 2020.
Results
A total of 1768 patients were included: 67 tracheostomised non-COVID-19 patients (historic cohort), 1371 COVID-19 patients that did not require ICU admission, 266 non-tracheostomised COVID-19 patients and 64 tracheostomised COVID-19 patients. Comparing the obesity prevalence, 54.69% of the tracheostomised COVID-19 patients were obese and 10.53% of the non-tracheostomised COVID-19 patients (
p
< 0.001). The median of ICU admission days was lower (
p
< 0.001) in the non-tracheostomised cohort (12.5 days) compared with the COVID-19 tracheostomised cohort (34 days). The incidence of haemorrhagic complications was significantly higher in tracheostomised COVID-19 patients (20.31%) compared with tracheostomised non-COVID-19 patients (5.97%) and presented a higher percentage of obesity, hypertension, diabetes and smoking, significantly different from the historic cohort (
p
< 0.001). A Cox model showed that tracheostomy had no statistically significant effect on mortality in COVID-19 patients.
Conclusion
Obesity and smoking may be risk factors for tracheostomy in COVID-19 patients, tracheostomised COVID-19 patients present a higher risk of bleeding complications than those admitted for other reasons and an elevated LDH and INR on ICU admission may be associated with increased mortality.
Purpose
The purpose is to analyze the incidence of acute infectious supraglottitis in our center between 2010 and 2020, define the characteristics and trends of those patients and identify factors associated with the need of airway intervention.
Methods
A retrospective single-center observational study of a cohort of patients diagnosed with acute infectious supraglottitis between January 2010 and December 2020. Patients were stratified according to airway management.
Results
Eighty eight patients were included: 59 men (67%) and 29 women (33%). A significant upward trend of 9% in the annual incidence rate of supraglottitis was seen during 2010–2020, with an important increase in cases during 2019. Muffled voice (41%) and respiratory distress (38%) were the most common presenting symptoms; and the median duration of symptoms before hospital admission was 2 days [IQR 1; 3]. Airway intervention was performed in fifteen patients (17%). Nine patients (10%) were intubated and six required tracheotomy (7%). Comparing the patients who required airway intervention with those who received a conservative treatment, younger patients (
p
< 0.01) were more likely to need airway intervention. In logistic regression analysis, we found that epiglottic abscess (
p
= 0.015), hypersalivation (
p
= 0.027) and smoking (
p
= 0.036) were independent factors with a significant association with airway intervention.
Conclusion
There was an important increase in cases and its severity in 2019, but due to COVID-19 pandemic, it was not possible to define if it was an isolate event or an upward trend. Epiglottic abscess, hypersalivation and smoking could be possible risk factors for airway intervention.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
