Stress Dose Steroids

WHEN IS STRESS DOSE STEROIDS INDICATED?

  • depends on history of steroid intake and likelihood of HPA supression + type and duration of surgery
  • NONSUPPRESSED HPA AXIS: 
    • < 3 weeks of steroids at any dose
    • prednisone <5mg/daily for any duration
    • prednisone <10mg every other day
    • PLAN:  continue same regimen perioperatively; no need for cosyntropin test or stress dose steroids
  • SUPPRESSED HPA AXIS
    • prednisone >20mg/day x 3 weeks or more OR Cushingoid appearance
    • PLAN:
      • give stress dose steroids based on type and duration of surgery (see below)
  • INTERMEDIATE HPA SUPPRESSION (Unknown HPA Axis suppression, previous 3 or more intraarticular or spinal steroid injections within 3 mos prior to suregery)
    • PLAN
      • evaluate HPA axis 
        • check AM cortisol (8a.m.) after 24h off steroids
        • if <5 ug/dL – likely suppressed axis; give stress dose steroids
        • if >10 ug/dL – likely no supression; continue current dose on day of surgery
        • if 5-10 ug/dL – ACTH stim test or empiric stress dose steroids
      • ACTH stim test (standard is 250 ug):
        • if serum cortisol <18 ug/dL 30 mins after ACTH – give stress dose steroids
        • if >serum cortisol >18 ug/dL 30 mins after ACTH – no stress dose steroids

 

STEROIDS BASED ON TYPE AND DURATION OF SURGERY

MINOR PROCEDURES / LOCAL ANESTHESIA – stress dose not necessary, take AM steroids

MODERATE SURGICAL STRESS: (eg. LE revascularization, total joint replacement)

  1. take AM steroids
  2. hydrocortisone 50mg IV prior to procedure, 25mg IV q8h x 24h
  3. resums usual dose after

MAJOR SURGICAL STRESS (e.g open heart surgery, proctocolectomy, esophagogastrectomy)

  1. take AM steroids
  2. hydrocortisone 100mg IV before induction of anesthesia
  3. hydrocortisone 50mg q8h x 24h
  4. taper by half per day to maintenance dose
