This study compares two methods of dosing methadone for complex spine cases

Patients with spine surgery experience a significant amount of pain that can interfere with
healing, rehabilitation and contribute to morbidity in the post-operative period. This study
will compare post-operative opioid requirement at 24 and 48 hours to determine if methadone
given in small aliquots until respiratory depression can act as a self-control to determine
the correct dose required.

Inclusion Criteria:

- Patients must consent to participate and sign the Institutional Review Board (IRB)
approved informed consent prior to beginning any study specific procedures.
