Cardiovascular and plasma cortisol responses to surgery in corticosteroid-treated R. A. patients

Perioperative Evaluation and Management of Patients on Glucocorticoids

Myriad questions regarding perioperative management of patients on glucocorticoids (GCs) continue to be debated including which patients are at risk for adrenal insufficiency (AI), what is the correct dose and duration of supplemental GCs, or are they necessary for everyone? These questions remain partly unanswered due to the heterogeneity and low quality of data, studies with small sample sizes, and the limited number of randomized trials. To date, we know that although all routes of GC administration can result in hypothalamic-pituitary-adrenal (HPA) axis suppression, perioperative adrenal crisis is rare. Correlation between biochemical testing for AI and clinical events is lacking. Some of the current perioperative management recommendations based on daily GC dose and duration of therapy may be difficult to follow in clinical practice. The prospective and retrospective studies consistently report that continuing the daily dose of GCs perioperatively is not associated with a higher risk for adrenal crises in patients with GC-induced AI. Considering that oral GC intake may be unreliable in the early postoperative period, providing the daily GC plus a short course of IV hydrocortisone 25 to 100 mg per day based on the degree of surgical stress seems reasonable. In patients who have stopped GC therapy before surgery, careful assessment of the HPA axis is necessary to avoid an adrenal crisis. In conclusion, our literature review indicates that lower doses and shorter duration of supplemental GCs perioperatively are sufficient to maintain homeostasis. We emphasize the need for well-designed randomized studies on this frequently encountered clinical scenario.

Stress Dose Steroids: Myths and Perioperative Medicine

Perioperative medication management for patients with systemic autoimmune inflammatory diseases has focused on strategies to improve outcomes and mitigate risks. The emphasis has been to minimize the risk of infection associated with most antirheumatic medications, while attempting to avoid flares of disease precipitated by medication withdrawal. Management of glucocorticoids in the perioperative period has been based on an assumption that supraphysiologic increases in dose were always necessary to avoid hypotension and shock in glucocorticoid treated patients, and alternative strategies were rarely considered despite the known infectious, metabolic, and wound healing risks associated with glucocorticoid administration. This paper will review current recommendations for perioperative glucocorticoid administration for glucocorticoid treated patients with systemic inflammatory autoimmune diseases and discuss glucocorticoid physiology to analyze the basis for these recommendations and consider alternative perioperative management strategies.

Supplemental corticosteroids for dental patients with adrenal insufficiency: reconsideration of the problem

BACKGROUND

Dental patients with primary or secondary adrenal insufficiency, or AI, may be at risk of experiencing adrenal crisis during or after invasive procedures. Since the mid-1950s, supplemental steroids in rather large doses have been recommended for patients with AI to prevent adrenal crisis.

METHODS

To evaluate the need for supplemental steroids in these patients, the authors searched the literature from 1966 to 2000 using MEDLINE and textbooks for information that addressed AI and adrenal crisis in dentistry. Reference lists of relevant publications and review articles also were examined for information about the topic.

RESULTS

The review identified only four reports of purported adrenal crisis in dentistry. Factors associated with the risk of adrenal crisis included the magnitude of surgery, the use of general anesthetics, the health status and stability of the patient, and the degree of pain control.

CONCLUSIONS

The limited number of reported cases strongly suggests that adrenal crisis is a rare event in dentistry, especially for patients with secondary AI, and most routine dental procedures can be performed without glucocorticoid supplementation.

CLINICAL IMPLICATIONS

The authors identify risk conditions for adrenal crisis and suggest new guidelines to prevent this problem in dental patients with AI.
