Perioperative medicine (London, England)·2025

Recent upper respiratory infections (URI) did not predict or prevent perioperative respiratory complications in afebrile children undergoing elective surgery. Anesthesiologists can proceed with surgery in this population, even with a URI, using specific criteria.

Area of Science:

  • Anesthesiology
  • Pediatric Surgery
  • Respiratory Medicine

Background:

  • Upper respiratory infections (URI) can increase the risk of perioperative respiratory complications.
  • Current thresholds for canceling surgery due to URI vary widely among clinicians.
  • Predicting and preventing these complications is crucial for patient safety.

Purpose of the Study:

  • To investigate if capnometry could predict autonomically-mediated complications during emergence from anesthesia.
  • To determine if preoperative bronchodilator administration could reduce these complications.
  • To assess the association between URI and adverse respiratory events in children undergoing elective surgery.

Main Methods:

  • A randomized controlled trial involving 109 afebrile children (2 months to 18 years) undergoing short, elective surgeries.

  • Patients received either bronchodilator premedication or placebo, with preoperative capnometry performed.
  • Respiratory events (cough, wheeze, stridor, laryngospasm, desaturations) were recorded during emergence from anesthesia.

    • Main Results:

    • No association was found between recent or active URI and adverse respiratory events.
    • Neither bronchodilator premedication nor preoperative capnometry predicted or prevented complications.
    • Endotracheal intubation was linked to increased desaturations, and saline placebo to increased coughing.

    Conclusions:

    • In this highly selected group of afebrile children, URI did not correlate with adverse respiratory events.
    • The findings suggest that anesthesiologists may safely proceed with elective surgery in afebrile children with URI, provided specific criteria are met.
    • Neither capnometry nor bronchodilators proved effective in predicting or preventing these complications in this population.
