Summary

Halothane anesthesia during pediatric bronchoscopy significantly exposes medical staff to the anesthetic gas, exceeding safe limits in poorly ventilated rooms. Total intravenous anesthesia is recommended as a safer alternative when ventilation is inadequate.

Area of Science:

  • Anesthesiology
  • Occupational Health
  • Pediatric Pulmonology

Background:

  • Inhalation anesthesia, specifically halothane, is commonly used for pediatric bronchoscopy.
  • Rigid bronchoscopes and inhalation anesthesia can lead to environmental contamination.
  • Occupational exposure limits for anesthetics exist to protect healthcare professionals.

Purpose of the Study:

  • To measure halothane exposure for anesthetists and endoscopists during pediatric bronchoscopy.
  • To assess exposure in a worst-case scenario (poor ventilation, no scavenging system).
  • To compare measured exposure levels with international occupational exposure limits.

Main Methods:

  • Ten pediatric patients (ASA I-III) underwent diagnostic bronchoscopy under halothane anesthesia.

  • Anesthesia was maintained with halothane (0.5-2.0 vol%) in 100% oxygen.
  • Halothane concentrations were measured in the breathing zones of staff using a direct-reading instrument in an operating room without air conditioning or scavenging.

    • Main Results:

    • Mean halothane exposure was 57.7 ppm for anesthetists and 96.3 ppm for endoscopists.
    • These levels significantly exceeded international threshold values (2-50 ppm).
    • Peak concentrations over 200 ppm were detected, indicating substantial exposure.

    Conclusions:

    • Halothane anesthesia during pediatric rigid bronchoscopy in poorly ventilated operating rooms leads to unacceptable occupational exposure.
    • Current international health guidelines for anesthetic gas exposure were significantly surpassed.
    • Total intravenous anesthesia is suggested as a safer alternative in environments with inadequate ventilation.
