Abstract
PURPOSE: Acute supraglottitis (SG) can potentially lead to rapid airway obstruction. The last few decades have witnessed a shift towards a more conservative approach in airway management of adult SG. This study aims to evaluate this watchful approach based on a large case series combined with a high-level meta-analysis of all reports in the English literature. METHODS: Retrospective case series and meta-analysis. The medical records of all adult patients diagnosed as having SG who were hospitalized in a large-volume tertiary referral center between January 2007 and December 2018 were reviewed. A meta-analysis was conducted on all English literature published between 1990 and 2018. RESULTS: A total of 233 patients (median age 49.1 years, 132 males), were admitted due to acute SG during the study period. No airway intervention was required in 228 patients (97.9%). Five patients (2.1%) required preventive intubation, and two of them (0.9%) were later surgically converted to a tracheotomy. Patients who required airway intervention had higher rates of diabetes (P = .001), cardiovascular diseases (P = .036) and other comorbidities (P = .022). There was no mortality. The meta-analysis revealed that the overall intubation rates random effects model was 8.8% [95% confidence interval (CI) 4.6%-14.0%] and that the tracheotomy random effects model was 2.2% (95% CI; 0.5%-4.8%). The overall mortality rate was 0.89%. CONCLUSIONS: This study provides evidence of low rates of surgical airway intervention in patients diagnosed with SG worldwide. A conservative approach in adult SG is safe and should be advocated. LEVEL OF EVIDENCE: 2.
