A 3-year-old with sleep-disordered breathing after a recent cold: proceed, postpone, or admit?
A 3-year-old boy (15 kg) is scheduled for adenotonsillectomy for recurrent tonsillitis and sleep-disordered breathing. His parents report loud snoring every night, witnessed apnoeas three to four times a week, and he falls asleep in the car within minutes. He has no syndromic features, no cardiac history and a normal examination apart from large tonsils. Two weeks ago he had a febrile upper respiratory tract infection; he is now afebrile with clear rhinorrhoea, a moist cough and a clear chest on auscultation. He was born at term, has had no previous anaesthesia and takes no regular medicines. The family lives 45 minutes from the hospital. The surgeon plans same-day discharge. The anaesthetic department has a policy that children under 3 years with obstructive sleep apnoea require overnight admission, but the surgeon disputes it.
1. Do you proceed with anaesthesia today, and how does the recent respiratory infection influence your decision?

The decision rests on distinguishing a resolving, afebrile upper respiratory infection from an active one, and on balancing the risks of proceeding against those of delay. Perioperative respiratory adverse events, particularly laryngospasm, bronchospasm and desaturation, are increased for up to about 2–4 weeks after a respiratory infection, and the risk is highest in the first two weeks and in children with reactive airways or sleep-disordered breathing. This child is at the favourable end of the spectrum: afebrile, chest clear, secretions clear rather than purulent, no malaise and no lower respiratory signs.
Given that this is elective surgery and that untreated obstructive sleep apnoea itself carries risk, I would proceed today, but with an explicit plan to minimise airway events. If he had fever, purulent sputum, productive cough, wheeze, crepitations or systemic upset, I would postpone for 2–4 weeks.
The airway plan should include a deep enough anaesthetic before any airway instrumentation, avoidance of unnecessary suctioning, a reinforced tracheal tube with a throat pack for surgical access, and either a carefully conducted deep extubation by an experienced anaesthetist or an awake extubation after thorough oropharyngeal suctioning. Volatile anaesthesia, adequate analgesia and antiemetic prophylaxis reduce coughing and laryngospasm. I would also confirm the child has been fasted appropriately and document the shared decision with the parents.
2. Outline an opioid-sparing analgesic and anaesthetic technique for this child.

The aim is to provide good analgesia while minimising respiratory depression in a child with sleep-disordered breathing. Give paracetamol 15 mg/kg intravenously and ibuprofen 10 mg/kg (if no contraindication) at induction, plus dexamethasone 0.15–0.5 mg/kg up to a maximum of about 8 mg for antiemesis and reduction of airway oedema. Ask the surgeon to infiltrate the tonsillar beds with a long-acting local anaesthetic, taking care to avoid excessive volume and intravascular injection.
Codeine is contraindicated after tonsillectomy in children, particularly those with obstructive sleep apnoea, because ultrarapid CYP2D6 metabolisers convert it to morphine and fatal respiratory depression has occurred. Tramadol is also best avoided in this group. If an opioid is needed, use small titrated doses of morphine (for example 0.05 mg/kg increments) and assess sedation and respiratory rate before each further dose rather than relying on a fixed regimen.
For anaesthesia, a volatile-based technique with a reinforced tube avoids the need for a large opioid dose. Avoid nitrous oxide to reduce postoperative nausea and vomiting, and give ondansetron 0.1 mg/kg. Extubate either deep with an experienced team or awake after suctioning. In recovery, continuous pulse oximetry and apnoea monitoring are essential, and the child should be observed for at least several hours before any discharge decision, with clear parental instructions about when to seek help.
3. How do you resolve the disagreement about same-day discharge?
Read the worked answer
The anaesthetist should frame this as a risk discussion rather than a territorial dispute. This child has three recognised risk factors for postoperative respiratory complications after adenotonsillectomy: age under 3 years, clinically significant obstructive sleep apnoea with witnessed apnoeas, and a substantial distance from hospital. Postoperative events, including apnoea, desaturation and opioid-related respiratory depression, tend to occur in the first postoperative night, when the family would be at home 45 minutes away.
Guidelines and the departmental policy both support overnight admission with continuous oximetry for young children with obstructive sleep apnoea. The surgeon can be offered a compromise: the child is listed first on the operating list, observed in a monitored recovery area for an extended period, and admitted only for one night with discharge the following morning if feeding and oxygen saturation are satisfactory. If the surgeon still disagrees, escalation to the clinical lead is appropriate, and the discussion should be documented.
It is also worth checking whether the child has features of severe disease, such as growth failure, cor pulmonale or very frequent apnoeas, which would strengthen the case for admission and possibly preoperative investigation. The parents should be involved in the decision and told why the overnight stay is recommended, so that they do not experience it as an arbitrary delay.
