Supplemental perioperative steroids for surgical patients with adrenal insufficiency

Peri-operative Replacement of Exogenous Steroids (PREdS): a national audit of current peri-operative prescribing for patients taking therapeutic steroids

INTRODUCTION

Approximately 1% of the UK population take oral corticosteroids for ≥ 28 days each year, for broadly two reasons: deficiency in corticosteroid requiring replacement; or therapeutic corticosteroid for inflammatory conditions. Acute deficiency can occur at times of physiological stress (e.g. surgery), potentially leading to major complications. The Association of Anaesthetists' 2020 consensus guideline provides detailed advice for the management of glucocorticoids during the peri-operative period for patients with adrenal insufficiency. This national audit aimed to assess compliance with this guideline.

METHODS

Data were collected from 59 Trusts over 14 consecutive days for all eligible patients undergoing procedures under the care of an anaesthetist. Patients who were prescribed ≥ 5 mg oral prednisolone equivalents pre-operatively, in whom supplementary corticosteroid would be indicated, were compared with those prescribed < 5 mg oral prednisolone equivalents.

RESULTS

Operations for 21,731 patients were audited: 277 (1.3%) patients were taking therapeutic corticosteroids. Detailed peri-operative data were collected for all patients receiving therapeutic corticosteroids: 201/277 (73%) were ASA physical status ≥ 3; 184/277 (66%) underwent elective procedures; and 252/277 (91%) were prescribed prednisolone pre-operatively, of whom 219/277 (79%) were prescribed ≥ 5 mg oral prednisolone equivalents. In the patients who were prescribed ≥ 5 mg oral prednisolone equivalents, 186/219 (85%) received pre-operative glucocorticoid supplementation and 97/219 (42%) received it postoperatively; however, only 67/219 (31%) and 43/219 (20%) respectively received glucocorticoid supplementation according to the guidelines. Overall, peri-operative prescribing was compliant in 19/219 (9%) patients. A similar proportion, 30/219 (14%), received no supplementation. In the patients taking < 5 mg oral prednisolone equivalents pre-operatively, 28/58 (48%) received inappropriate supplementation.

CONCLUSIONS

Despite 125/277 (45%) of anaesthetists reporting Association of Anaesthetists' guidelines use, compliance remained low, with adherence in only 27/125 (22%) patients. Further research is required to identify the correct peri-operative strategy for patients taking therapeutic corticosteroids.

Survival of conventional dental implants in the edentulous atrophic maxilla in combination with zygomatic implants: a 20-year retrospective study

PURPOSE

Implant-supported prosthetic rehabilitation in the resorbed maxilla is a great challenge. The aim of this study was to determine the survival rate of conventional anterior implants placed in combination with zygomatic implants according to the Brånemark technique, and to identify risk factors for implant failure.

METHODS

We collected data retrospectively from 72 consecutive patients who received treatment from 1998 to 2018 at our center, according to Brånemark's original technique. Kaplan-Meier analysis was conducted to assess survival rate, and a survival regression model was used with the patient as the random factor, applying the Weibull distribution.

RESULTS

A total of 236 maxillary anterior implants were included, with a mean follow-up of 12.1 years. Kaplan-Meier analysis showed overall cumulative survival rates of 95.3% at 1 year, 94.8% at 2 years, 93.0% at 5 years, 90.5% at 10 years, 81.6% at 15 years, and 67.7% at 20 years. Survival regression showed an association between bruxism and implant failure as well as implants bearing an overdenture. Implants with length ≤ 10 mm had a significantly lower survival time. No significant association was found between the number of anterior implants and survival rate.

CONCLUSIONS

We found acceptable long-term anterior conventional implant survival. Significant risk factors for failure were bruxism, overdentures, and implants shorter than 10 mm.

Perioperative corticosteroid administration: a systematic review and descriptive analysis

Background

Perioperative administration of corticosteroid is common and variable. Guidelines for perioperative corticosteroid administration before non-cardiac non-transplant surgery in patients with current or previous corticosteroid use to reduce the risk of adrenal insufficiency are lacking. Perioperative use of corticosteroid may be associated with serious adverse events, namely hyperglycemia, infection, and poor wound healing.

Objective

To determine whether perioperative administration of corticosteroids, compared to placebo or no intervention, reduces the incidence of adrenal insufficiency in adult patients undergoing non-cardiac surgery who were or are exposed to corticosteroids.

Methods

We searched MEDLINE via Ovid and PubMed, EMBASE via Ovid, and the Cochrane Central Register of Controlled Trials, all from 1995 to January 2017.

Selection criteria

We included randomized controlled trials (RCTs), cohort studies, case-studies, and systematic reviews involving adults undergoing non-cardiac non-transplant surgery and reporting the incidence of postoperative adrenal insufficiency.

Data collection and analysis

Two authors independently assessed studies' quality and extracted data. A descriptive and bias assessment analysis was performed.

Results

Two RCTs (total of 37 patients), five cohort studies (total of 462 patients), and four systematic reviews were included. Neither RCT showed a significant difference in the outcome. This result was like that of the five cohort studies. The quality of the evidence was low.

Conclusion

The current use of perioperative corticosteroid supplementation to prevent adrenal insufficiency is not supported by evidence. Given the significant studies' limitations, it is not possible to conclude that perioperative administration of corticosteroids, compared to placebo, reduces the incidence of adrenal insufficiency.

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.

Perioperative management in myasthenia gravis: republication of a systematic review and a proposal by the guideline committee of the Japanese Association for Chest Surgery 2014

Thymectomy is regarded as a useful therapeutic option for myasthenia gravis (MG), though perioperative management in MG patients is largely empirical. While evidence-based medicine is limited in the perioperative management of MG patients, treatment guidelines are required as a benchmark. We selected issues faced by physicians in clinical practice in the perioperative management of extended thymectomy for MG, and examined them with a review of the literature. The present guidelines have reached the stage of consensus within the Japanese Association for Chest Surgery.

Perioperative stress-dose steroids

Supraphysiologic corticosteroid doses have routinely been considered the perioperative standard of care over the past six decades for patients on long-term steroid therapy. However, the accumulation of data over this period is beginning to suggest that such a practice may not be necessary. The majority of these studies are retrospective reviews or small prospective cohorts, but there are two small prospective, randomized placebo-controlled trials, one prospective primate trial, and several systematic reviews addressing the issue. Based on this developing evidence, patients on long-term exogenous steroids do not require high-dose perioperative corticosteroids and should instead remain on their baseline maintenance dose, with the understanding that secondary adrenal insufficiency should be considered for unexplained perioperative hypotension in these patients.

Reducing surgical site infection in arthroplasty of the lower limb: A multi-disciplinary approach

Objectives

To review the current best surgical practice and detail a multi-disciplinary approach that could further reduce joint replacement infection.

Methods

Review of relevant literature indexed in PubMed.

Results

Surgical site infection is a major complication following arthroplasty. Despite its rarity in contemporary orthopaedic practice, it remains difficult to treat and is costly in terms of both patient morbidity and long-term health care resources.

Conclusions

Emphasis on education of patients and all members of the health-care team and raising awareness in how to participate in preventative efforts is imperative.

Supplemental perioperative steroids for surgical patients with adrenal insufficiency

BACKGROUND

Adrenal crisis is a life threatening condition which can be induced by stress during surgery in patients with adrenal insufficiency. This may be prevented by perioperative administration of high doses of steroids. There is disagreement on whether supplemental perioperative steroids are required and, when administered, on the amount and frequency of doses. The review was originally published in 2009 and was updated in 2012.

OBJECTIVES

To assess whether it is necessary to administer supplemental perioperative steroids in adult patients on maintenance doses of glucocorticoids because of adrenal insufficiency.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 2); MEDLINE (1966 to February 2012); EMBASE (1980 to February 2012); LILACS (1982 to May 2012); and the databases of ongoing trials. We handsearched the Journal of Clinical Endocrinology and Metabolism (1982 to 2008), Clinical Endocrinology (1972 to 2008), Surgery (1948 to 1994), Annals of Surgery (1948 to 1994), and Anaesthesia (1948 to 2001). The original search was performed in January 2009.

SELECTION CRITERIA

We included randomized controlled trials that compared the use of supplemental perioperative steroids to placebo in adult patients on maintenance doses of steroids and who required surgery.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial quality and extracted data. Study authors were contacted for missing information. We used mean differences and standard deviations to summarize the data for each group.

MAIN RESULTS

Two trials involving 37 patients were included. These studies reported that supplemental perioperative steroids were not required during surgery for patients with adrenal insufficiency. Neither study reported any adverse effects or complications in the intervention and control groups. Both studies were graded as having a high risk of bias.

AUTHORS' CONCLUSIONS

Owing to the small number of patients, the results may not be representative. Based on current available evidence, we are unable to support or refute the use of supplemental perioperative steroids for patients with adrenal insufficiency during surgery.

Intraoperative adrenal insufficiency in a patient with prader-willi syndrome

Prader-Willi syndrome (PW) is a rare genetic disorder with multi-organ system involvement. These patients present many perioperative challenges including sleep-related breathing disorders, morbid obesity, thick salivary secretions, mental retardation, and difficult intravenous access. PW has been suggested to be associated with central adrenal insufficiency. We report a novel case of persistent severe hypotension from previously undiagnosed and asymptomatic adrenal insufficiency in a pediatric patient with Prader-Willi syndrome during spine surgery that resolved upon treatment with hydrocortisone.

[Preoperative evaluation of adult patients prior to elective, non-cardiac surgery. Joint recommendations of German Society of Anesthesiology and Intensive Care Medicine, German Society of Surgery and German Society of Internal Medicine]

Evaluation of the patient's medical history and a physical examination are the cornerstones of risk assessment prior to elective surgery and may help to optimize the patient's preoperative medical condition and to guide perioperative management. Whether the performance of additional technical tests (e.g. blood chemistry, ECG, spirometry, chest-x-ray) can contribute to a reduction of perioperative risk is often not very well known or controversial. Similarly, there is considerable uncertainty among anesthesiologists, internists and surgeons with respect to the perioperative management of the patient's long-term medication. Therefore, the German Scientific Societies of Anesthesiology and Intensive Care Medicine (DGAI), Internal Medicine (DGIM) and Surgery (DGCH) have joined to elaborate and publish recommendations on the preoperative evaluation of adult patients prior to elective, non-cardiac and non-lung resection surgery. In the first part the general principles of preoperative evaluation are described (part A). The current concepts for extended evaluation of patients with known or suspected major cardiovascular disease are presented in part B. Finally, the perioperative management of patients' long-term medication is discussed (part C). The concepts proposed in these interdisciplinary recommendations endorsed by the DGAI, DGIM and DGCH provide a common basis for a structured preoperative risk assessment and management. These recommendations aim to ensure that surgical patients undergo a rational preoperative assessment and at the same time to avoid unnecessary, costly and potentially dangerous testing. The joint recommendations reflect the current state-of-the-art knowledge as well as expert opinions because scientific-based evidence is not always available. These recommendations will be subject to regular re-evaluation and updating when new validated evidence becomes available.
