Perioperative Temperature Management in Children: What Matters?

Area of Science:

• Pediatric Anesthesiology
• Perioperative Medicine
• Patient Safety

Background:

• Inadvertent perioperative hypothermia is a common complication in children undergoing surgery.
• Existing guidelines for pediatric temperature management are often based on adult data and may not be effective.
• There is a need to identify specific risk factors and effective interventions for pediatric hypothermia.

Purpose of the Study:

• To identify risk factors associated with inadvertent perioperative hypothermia in pediatric patients.
• To evaluate the effectiveness of current interventions in preventing hypothermia in this population.

Main Methods:

• A prospective observational study was conducted in 869 pediatric patients (<16 years) undergoing anesthesia.
• Data collected included patient demographics, surgical and anesthetic details, monitoring, warming measures, and operating theater (OT) temperature.
• Hypothermia was defined as tympanic core temperature < 36°C upon arrival to the postanesthetic care unit.

Main Results:

• The incidence of postoperative hypothermia was 12.3%.
• Factors independently protective against hypothermia included: higher ambient OT temperature, intraoperative temperature monitoring, use of occlusive dressings, and active forced-air warming.
• Emergency procedures were associated with a lower incidence of hypothermia compared to elective procedures.

Conclusions:

• Routine core temperature monitoring and active forced-air warming are effective in preventing pediatric hypothermia.
• Occlusive covers and maintaining optimal ambient OT temperatures are cost-effective and safe preventive measures.
• These findings support the implementation of targeted interventions to improve pediatric perioperative temperature management.
