Evaluation of American Society of Anesthesiologists classification as 30-day morbidity predictor after single-level elective anterior cervical discectomy and fusion

Although we did not detect associations between ASA class >II and adverse 30-day outcomes following SLE-ACDF, imprecision of estimates precludes definitive inferences. Although ASA classification allows simple assessment of patients' physiological status, their overall perioperativerisk factors need to be considered collectively for adequate optimization and improved outcomes in SLE-ACDF.
