5. Equipment management after endotracheal intubation • All used airway equipment should be placed in double zip-locked plastic bags and removed for disposal or disinfection. • Used laryngoscopes should be sealed in double zip-locked plastic bags as soon as the endotracheal intubation is complete, to prevent further contamination of the surroundings. • End-tidal carbon dioxide sample lines and traps should be replaced. • Take care to avoid contaminating various instruments in the operating room, such as stethoscopes, pens, and telephones.
