Atelectasis is a common perioperative complication. It has been reported [Day surgery refers to operations that require the participation of anesthesiologists within 24 h from admission to discharge. These children were hospitalised for a shorter period of time for observation and are prone to complications such as pulmonary infection after discharge due to the presence of atelectasis. Therefore, it is important to pay more attention to postoperative atelectasis in children who underwent day surgery.Laryngeal mask is a supraglottic airway tool, which has been commonly used in clinical because of its non-invasiveness, less damage, and easy to insert. Now, the use of laryngeal mask instead of tracheal intubation for airway management has been achieved in day surgery, therefore, how to performe a respiratory management with a laryngeal mask is particularly important.It was reported that muscle relaxants may lead to an increase in postoperative pulmonary complications, and laryngeal mask retention of spontaneous breathing can reduce the incidence of reflux aspiration, so laryngeal mask retention of spontaneous breathing has become a common method of respiratory management for children [
