AbstractAmong some kinds of cervical spine surgeries, combined anterior-posterior cervical spine surgery (CAP-CS surgery) requires prolonged operative time and highly invasive procedure. This study was performed to determine whether CAP-CS surgery was associated with increased risk of emergency airway management compared with other cervical spine surgeries (O-CS surgeries). The records of the patients who underwent cervical spine surgery between July 2001 and March 2003 at our institution were reviewed retrospectively, and we determined whether the CAP-CS surgery was associated with an increased risk of emergency airway management in comparison with O-CS surgeries, using the logistic regression analysis. A total of 165 were eligible for inclusion in the study. A total of 127, 20, 11, 5, and 2 patients suffered from cervical myelopathy, traumatic cervical spinal cord injury, atlantoaxial dislocation, cervical spinal tumors, and cervical pyogenic spondylitis, respectively. The operative approaches were CAP-CS surgery, anterior surgery, posterior surgery, and atlantoaxial surgery in 10, 56, 88, and 11 patients, respectively. Thus, the operative approaches were CAP-CS surgery in 10 patients and O-CS surgeries in 155 patients. Postoperative emergency airway management was required in 7 of the 10 patients (70%) who underwent CAP-CS surgery, and 2 of the 155 patients (1%) who underwent O-CS surgeries. The increased risk of postoperative emergency airway management imposed by CAP-CS surgery was 178.5 by an odds ratio, with a 95% confidence interval of 25.6 to 1246. The results show that CAP-CS surgery provides a major risk factor for postoperative emergency airway management.
