Risk factors for reintubation after anterior cervical discectomy and fusion surgery: evaluation of three observational data sets.

Overview
abstract
PURPOSE: Postoperative loss of airway requiring reintubation is a rare but potentially catastrophic complication following anterior cervical discectomy and fusion (ACDF). We sought to identify risk factors asscociated with reintubation within one day following ACDF. Attention was focused on patient demographics, comorbidities, and factors potentially linked to soft tissue swelling and hematoma formation that could compromise the upper airway. METHODS: We performed a retrospective cohort study of patients who underwent ACDF procedures at a high-volume institution from 2005 to 2014 (n = 3,041), participating hospitals in the National Surgical Quality Improvement Program (NSQIP) (n = 47,425), and Premier Healthcare (n = 233,633) databases from 2006 to 2016. Separate multivariable logistic regression models using the NSQIP and Premier samples were used to identify risk factors for reintubation within one day of ACDF. Odds ratios (OR) and 95% confidence intervals (CI) are reported. RESULTS: Incidence of reintubation within one day of ACDF was 0.19% in the institutional database and 0.21% in NSQIP and Premier databases. Risk factors for reintubation included older age, male sex, high comorbidity burden, procedures performed at large hospitals, non-elective procedures, Medicaid insurance, and use of heparin or more than one anticoagulant. Intravenous or oral steroid use (OR, 0.45; 95% CI, 0.36 to 0.56; P < 0.001) and delayed extubation (OR, 0.28 95% CI, 0.16 to 0.49; P < 0.001) were found to decrease risk of reintubation. CONCLUSIONS: Across three complementary data sets, incidence of reintubation within one day of ACDF was approximately 0.20%. Increased risk of reintubation associated with anticoagulant administration suggests upper airway hematoma as an underlying etiology. Steroid administration and delayed extubation may be useful in patients considered to be at higher risk for reintubation.
