Sleep Quality - Comparing the Effect of Ondansetron or Dexamethasone Given as Routine Prophylaxis Intraoperatively to Prevent Post Operative Nausea and Vomiting

Nausea and vomiting are common complications after anaesthesia, and anaesthetists routinely give medications to prevent them. Dexamethasone and ondansetron are the two most commonly used agents and have a long safety record. However, their effects on sleep, behaviour, and overall recovery are not well studied. Understanding these will guide future care. The aim of this study is to determine if dexamethasone or ondansetron given during an anaesthetic affect post-operative sleep, behaviour and recovery in children.

Patients enrolled in the study will be randomised to receive either dexamethasone or ondansetron during their procedure. This randomisation will be blinded to patients, their families and their treating anaesthetist. Information about the patient's pain, recovery and sleep will be collected over 7 days post-operatively using online surveys.

A subset of patients will also be asked to complete additional pre-operative non-invasive monitoring using an oximeter and an actigraph to measure their sleep quality before and after surgery. In addition to the postoperative surveys, these patients will be asked to wear the oximeter and actigraph for 3 nights before and immediatey after surgery. Patients who are admitted overnight postoperatively will also have additional transcutaneous carbon dioxide monitoring on the night of their surgery.

Detaljert beskrivelse

Postoperative nausea and vomiting (PONV) are a common complication after anaesthesia. Therefore, it is standard practice to administer either ondansetron and/or dexamethasone intraoperatively as prophylaxis. PONV affects up to 30-40% of the general surgical population and up to 80% of high-risk patients, making it one of the most distressing complications of the perioperative period.Uncontrolled PONV prolongs recovery room stay, increases unplanned hospital re-admissions, and is consistently identified by patients and families as one of the most undesirable aspects of the surgical experience. It was ranked in the top 10 research priorities in perioperative medicine in a recent large consumer engagement study involving over 350 children.

Ondansetron, a 5-HT3 receptor antagonist, and dexamethasone, a corticosteroid, are the two most widely used agents for PONV prophylaxis in paediatric anaesthesia, often administered in combination.Dexamethasone exerts well-documented glucocorticoid effects, including modulation of the hypothalamic-pituitary-adrenal (HPA) axis, suppression of endogenous cortisol secretion, and direct actions on brain structures involved in arousal and sleep regulation, including the hippocampus, hypothalamus, and limbic system.a single intraoperative dose of dexamethasone (0.1-0.5 mg/kg) has been shown to produce measurable HPA axis suppression lasting 24-48 hours postoperatively in children, as well as transient elevations in blood glucose and behavioural changes including hyperactivity, irritability, and emotional lability.

Sleep is a critical component of paediatric postoperative recovery. Disrupted postoperative sleep has been associated with increased pain perception, impaired immune function, heightened parental anxiety, and prolonged behavioural disturbance following surgery. Glucocorticoids are known to disrupt sleep architecture, including fragmentation of sleep, suppression of slow-wave sleep, and reductions in total sleep time. In children, the effects of a single perioperative dose of dexamethasone on sleep remain poorly characterised. In contrast, ondansetron does not directly affect the HPA axis or glucocorticoid receptors, and its central effects are limited primarily to 5-HT3 receptor blockade, with no established direct mechanism for sleep disruption. Postoperative negative behavioural changes (PNBC) in children, sometimes referred to as "new-onset behavioural problems", are a recognised sequela of paediatric anaesthesia and surgery, affecting up to 54% of children in the first 2 weeks following surgery. The potential role of perioperative dexamethasone in exacerbating these changes through glucocorticoid-mediated effects on the developing brain has not been systematically examined. Understanding whether the choice of PONV prophylaxis agent influences postoperative sleep quality and behaviour could have important implications for anaesthetic practice and family-centred postoperative care.

This study aims to investigate the impact of intraoperative intravenous dexamethasone vs ondansetron administered for prophylaxis of postoperative nausea and vomiting (PONV) on postoperative sleep, behaviour and recovery in children undergoing general anaesthesia.

Each individual PRAE (laryngospasm, bronchospasm, desaturation, airway obstruction, severe persistent coughing and post-operative stridor) will be considered separately.
