Dexamethasone has been used widely in clinical specialties including anesthesia. It is regarded as one of the ideal peri-operative agent being readily available, cheap, anti-inflammatory agent, prevents and treats post-operative nausea and vomiting (PONV), promotes appetite, suppress inflammation, a good analgesic agent both as intravenously or as an adjuvant to peripheral nerve blocks, it provides a sense of well-being and is considered to have a good quality of recovery and early discharge in patients from anesthesia. Controversial role of dexamethasone in causing post-operative surgical site infections have been solved and overall adverse effects of dexamethasone are rare and its benefits out-weighs the risks involved. The author did a literature search in Google Scholar and PubMed databases (latest articles related to the role of dexamethasone in peri-operative period over a period of two years 2015-17).

KEY MESSAGES:Dexamethasone has a tremendous role in preventing post-operative nausea and vomiting, it has a fair analgesic action if given intravenously, epidurally or perineurally, patients receiving dexamethasone have enhanced recovery profiles after surgery and single dose would usually not increase the risk of surgical site infections. Overall adverse effects of dexamethasone are rare and its benefits out-weighs the risks involved.Dexamethasone has been used widely in clinical specialties including anesthesia. The biological half-life is about 3 hours, although the duration of action may be much longer. Dexamethasone is bound to plasma proteins in much lower-levels than other glucocorticoids. Hepatic metabolism (both glucuronidation and sulfation) occurs to produce inactive metabolites, with 65% of the dose of dexamethasone excreted in the urine within 24 hours, with less than 3% unchanged.
