• Research summary

  Postoperative nausea and vomiting (PONV) is one of the most common complications affecting patients after major surgery. Patients undergoing bowel surgery are at a relatively high risk of developing these symptoms. This is often multifactorial and such patients are often exposed to various causative agents. Following surgery, patients view nausea and vomiting as a very undesirable effect, often reported as even more unpleasant than pain. It can cause significant consequences and given that over 60,000 bowel operations are performed in the UK annually, PONV is important because of its implications. Although the final outcome of surgery is rarely affected, PONV can cause significant complications such as dehydration, delayed return to oral diet, physiological disturbances and thus prolonging hospital stay. Delayed recovery predisposes to serious and life threatening complications such as hospital acquired pneumonia and thromboembolic events (deep vein thrombosis and pulmonary embolism). The delay in resuming an oral diet affects nutrition and subsequent general well being, predisposing to tissue breakdown, wound infection, fatigue, and weakness. For these reasons, reducing the severity of PONV is particularly important. Dexamethasone is a steroid drug widely but not universally used in attempt to prevent PONV by anaesthetists, and single dose dexamethasone has been reported to reduce PONV and perioperative fatigue. Its precise mechanism of action is unknown but it has anti-emetic properties and is known to improve appetite aiding early recovery. Small studies have shown a reduction in PONV amongst patients undergoing various types of surgery who are given dexamethasone. However no multicentre trial has been undertaken. Its potential benefits for patients undergoing bowel surgery need to be investigated. The findings would ensure its appropriate use in the future.
