Intraoperative Steroid Administration Guidelines

Introduction to Intraoperative Steroid Use

The primary rationale for administering IV steroids intraoperatively is to prevent adrenal crisis in patients on chronic steroid therapy who cannot produce adequate endogenous cortisol in response to surgical stress, and to provide equivalent dosing when patients are unable to take oral medications 1, 2

Patients on chronic steroid therapy (≥20 mg/day prednisone or equivalent for ≥3 weeks) must continue their usual steroid dose during surgery via IV route when oral intake is not possible 1, 2
The conversion is straightforward: prednisolone 5 mg = hydrocortisone 20 mg = methylprednisolone 4 mg 3
If unexplained, fluid-unresponsive hypotension occurs intraoperatively, administer 100 mg IV hydrocortisone immediately as a rescue dose, followed by 50 mg IV hydrocortisone every 6 hours 1, 2, 4

Current evidence does NOT support routine "push-dose" or "stress-dose" steroids (200-300 mg hydrocortisone) for all patients on chronic steroids 1, 2, 5, 6
The World Journal of Emergency Surgery guidelines explicitly state there is no evidence supporting routine stress dosing, and patients can maintain adequate endogenous steroid production if they continue their usual dose 1, 2, 5

Do not routinely administer high-dose stress steroids to all patients on chronic steroids—continue their usual equivalent IV dose instead 1, 2, 5
Reserve rescue dosing (100 mg hydrocortisone IV) for unexplained hypotension unresponsive to fluids and vasopressors 1, 2, 4
Patients on chronic steroids have a 7-fold increased risk of anastomotic leak in colorectal surgery and higher rates of wound dehiscence, infections, and mortality 4
The British Society of Gastroenterology recommends stopping or minimizing steroids before elective surgery when possible to reduce complications 3

Chronic steroid therapy = ≥20 mg/day prednisone equivalent for ≥3 weeks 1, 2
Convert oral dose to IV equivalent (prednisolone 5 mg = hydrocortisone 20 mg) and administer as scheduled doses or continuous infusion 3
Watch for unexplained hypotension unresponsive to fluids/vasopressors and if suspected, give 100 mg hydrocortisone IV immediately, then 50 mg IV q6h 1, 2, 4

The World Journal of Emergency Surgery defines chronic steroid therapy as taking ≥20 mg/day prednisone or equivalent for at least 3 weeks 7, 8
Patients on steroids for >1 year may have hypothalamic-pituitary-adrenal (HPA) axis suppression, according to the World Journal of Emergency Surgery 9, 10

The World Journal of Emergency Surgery recommends reviewing steroid dosage, duration, and indication 7, 11
Assess for signs of Cushing's disease (moon facies, buffalo hump, central obesity, skin thinning), as suggested by the World Journal of Emergency Surgery 10

Patients should continue their usual daily steroid dose during the perioperative period, as recommended by the World Journal of Emergency Surgery and Gut 7, 12
For patients on oral steroids, convert to equivalent IV dose while nil by mouth (prednisolone 5 mg = hydrocortisone 20 mg = methylprednisolone 4 mg), according to Gut 12

Be prepared to administer rescue steroids if unexplained hypotension occurs: 100 mg IV hydrocortisone followed by 50 mg IV hydrocortisone every 6 hours, as recommended by the World Journal of Emergency Surgery 9, 10
Monitor closely for signs of adrenal crisis (unexplained hypotension unresponsive to fluid resuscitation), as suggested by the World Journal of Emergency Surgery 7, 9

Patients on chronic steroids have a 7-fold increased risk of anastomotic leak in colorectal surgery, according to the World Journal of Emergency Surgery 9
Consider diverting stoma for high-risk anastomoses, especially in patients with inflammatory bowel disease on high-dose steroids, as recommended by the World Journal of Emergency Surgery 9
