The purpose of this retrospective study was to investigate the incidence and risk factors for DI and airway management in RH evacuation following ACSS. A series of 37 consecutive patients who developed RH following ACSS were retrospectively identified at Peking University Third Hospital from March 2010 to March 2022. Patients were categorized into the DI group or no-DI group. Demographic, clinical symptom, and airway assessment data were recorded to identify risk factors for DI. Continuous variables conforming to a normal distribution are expressed as the mean ± standard deviation, and comparisons between two groups were performed via Student’s t test. A nonnormal distribution was represented by the median (interquartile range), and the Mann–Whitney U test was used for comparisons between two groups. Significant differences in categorical variables were assessed using Fisher’s exact test. P < 0.05 was considered to indicate statistical significance. A binary logistic regression model was applied to distinguish multivariate predictors, with odds ratios (ORs) and 95% confidence intervals (95% CIs) used to indicate the intensity of association. All the statistical analyses were performed using IBM SPSS Statistics for Windows, version 22.0 (IBM Corp., Armonk, NY, USA).
