Overview
Brief Summary
This prospective, randomized, double blind, controlled study evaluates the effect of perioperative IV steroids versus saline on swallowing after anterior cervical spine surgery.
Detailed Description
This investigation is a prospective, randomized, double-blind, controlled trial testing peri-operative steroids versus saline and the effect on swallowing after anterior cervical spine surgery. Swallowing symptoms will be measured using the patient reported Bazaz (Bazaz) scale and the Dysphagia Short Questionnaire (DSQ). Swallowing data will be obtained pre-operatively, one day and two days post-operatively and then one week, two weeks, four weeks, three months, six months, and one year post-operatively. Patient clinical outcomes will be captured using web-based progress reports. Patients will complete the Quality of Life (QoL-12), Neck Disability Index (NDI), and Visual Analog Scale (VAS) questionnaires electronically pre-operatively and at one year post-operatively. This outcome data will help us analyze the swallowing function or symptoms with the overall clinical course of the patients enrolled in this study.

Arms & Interventions
Treatment 1; Dexamethasone
Patients undergoing elective anterior cervical spine surgery will be seen by spine surgeons. After consent the Bazaz and Dysphagia Short Questionnaire will be administered at baseline prior to surgery, Day 1, Day 2, 1 week, 2 weeks, 1 month, 3 months, 6 months, and 12 months after surgery. Patients will be randomized to either the steroid administration group or the saline administration group. Patients randomized to the experimental (steroid) group will receive 0.3 mg/kg of intravenous dexamethasone within one hour of the incision, then 0.15 mg/kg every eight hours for two doses. This dosage is approximately 20 mg, 10 mg, and 10 mg of dexamethasone. Patients in the control(saline) group will receive a similar volume of saline on the same schedule for three doses.
Intervention: Treatment 1; Dexamethasone
Treatment 0; Saline placebo

Outcomes
Primary Outcomes
Swallowing Difficulty
Time Frame: 1 day; 2 days; 1 week; 2 weeks; 1 month; 3 months; 6 months;12 months
Two measurement surveys were used: The Dysphagia Short Questionnaire: An Instrument for Evaluation of Dysphagia (DSQ) and Bazaz Dysphagia Scale (Bazaz). The DSQ and Bazaz determine levels of dysphagia over time after anterior cervical spine surgery. A DSQ score of zero indicates no symptoms. Any number above zero indicates difficulty swallowing. The Bazaz score of Zero indicates no symptoms. Any number above zero indicates difficulty swallowing. Numbers of subjects reporting any difficulty swallowing (had to have a score of at least 1) at various time points are listed below associated with the randomization assignment and survey used.
Secondary Outcomes
- Fusion Rate Steroid vs Placebo(1 year)
- Change in Quality of Life(Baseline and 1 year (or last visit as appropriate). Not all subjects followed up at 1 year.)
