A Phase 4 interventional study of Dexamethasone postoperative and Standard of Care in Adolescent Idiopathic Scoliosis (AIS), sponsored by Emory University. Completed at 1 site in United States. Open to participants aged 10 Years to 18 Years. Per ClinicalTrials.gov, last updated 2026-06-09.
Sponsored by Emory University · Phase 4, Interventional, and Treatment
The objective of this study is to perform a prospective, randomized controlled trial investigating the clinical usage of perioperative dexamethasone usage on APR activation, postoperative morphine usage, postoperative nausea, and hospital length of stay.
There will be a control control and a Dexamethasone cohort. Participants will be randomized into one of the two cohorts. Patients in the control group will receive one 8mg dose of dexamethasone intraoperatively as per standard of care anesthesia protocols. Patients randomized to the dexamethasone cohort will be administered 8 mg of dexamethasone with 3 additional doses administered at 8-hour intervals following surgery for a total of 4 doses. All study activities will tale place at Egleston during the patient's planned inpatient stay for their posterior spinal fusion.
This project has the potential to validate the utility of dexamethasone as a way to optimize postoperative care following PSF for AIS by minimizing the need for opioid medications and enhancing mobility and recovery.

The acute phase response (APR) is the body's response to induced tissue injury to facilitate, survive, and activate tissue repair. Posterior spinal fusion (PSF) is one source of tissue injury that has the potential to evoke an exuberant APR which can lead to a hyper-inflammatory state that can be associated with increased pain and patient morbidity. Perioperative steroid use has emerged as one potential method to minimize the activation of the APR as well as decrease postoperative pain and also narcotic utilization. However, the extent of the steroid usage on abating the activation of the APR in PSF for adolescent idiopathic scoliosis (AIS) has not been previously investigated.
The APR plays significant roles not only in the activation of inflammation postoperatively, but also for hemostasis as it helps trigger the initial fibrin clot to seal bleeding vessels.1 The inflammatory response is a later effect, that again plays a role in coagulation but also guides the transition from the survival phase response following tissue injury to the reparative phase. However, when a hyper-inflammatory state is present due to an exuberant APR activation, this transition to the reparative phase is unable to progress, resulting in a perpetuation of inflammation activation resulting in increased pain, nausea, respiratory distress, venous thromboembolism, infection, and even death.2 The ability to minimize or prevent the development of this hyper-inflammatory state holds significant implications not only for improved post-operative pain and nausea, but also for decreased postoperative complications, decreased length of stay, and resultant decreases in hospital costs.

Exclusion Criteria:
Patients will be screened for participation following indication for surgery by the treating surgeon and/or research assistant. Patients who elect to participate will then be randomized into either the dexamethasone or control groups. Patients in the control group will receive one 8mg dose of dexamethasone intraoperatively as per standard of care anesthesia protocols. No sham medication will be utilized for control subjects.
Drug: Standard of Care
Patients will be screened for participation following indication for surgery by the treating surgeon and/or research assistant. Patients who elect to participate will then be randomized into either the dexamethasone or control groups. Patients randomized to the dexamethasone cohort will be administered 8 mg of dexamethasone with 3 additional (8mg doses) administered at 8-hour intervals following surgery for a total of 4 doses.
Drug: Dexamethasone postoperative
Patients randomized to the dexamethasone cohort will be administered 8 mg of dexamethasone with 3 additional (8mg doses) administered at 8-hour intervals following surgery for a total of 4 doses. All patients will undergo a standardized post-operative pathway in the hospital following surgery that has been utilized for all AIS patients at our center since 2014.

All patients will undergo a standardized post-operative pathway in the hospital following surgery that has been utilized for all AIS patients at our center since 2014.
Changes in C-Reactive Protein
Laboratory studies to be collected will include c-reactive protein (CRP). Laboratory studies will be performed prior to surgery, post-operatively in the post-anesthesia care unit, and every morning during the in-hospital stay up to 48 hours. Studies will be analyzed in the hospital laboratory using standard sample analysis. No more than 10cc will be collected at each lab draw.
Time frame: Immediately pre-surgery, immediately post-surgery, 24 hours post-surgery, 48 hours post-surgery
Changes in Interleukin-6
Laboratory studies to be collected will include IL-6. Laboratory studies will be performed prior to surgery, post-operatively in the post-anesthesia care unit, and every morning during the in-hospital stay up to 48 hours. Studies will be analyzed in the hospital laboratory using standard sample analysis. No more than 10cc will be collected at each lab draw.
Time frame: Immediately pre-surgery, immediately post-surgery, 24 hours post-surgery, 48 hours post-surgery
Changes in Total morphine usage
Changes in total morphine dosage (measured in morphine equivalents) during the hospital stay will be assessed and compared between the two groups.
Time frame: Immediately post surgery, 24 hours post-surgery and 48 hours post-surgery
