LMA removal strategy

Details and patient eligibility

About

Laryngeal mask airway(LMA) is now a widely accepted airway device in general anesthesia for children. LMA removal after operation is always practiced in post-anesthesia-care-unit(PACU). The removal timing depends on recovery of spontaneous respiration and wash-out of inhalation anesthetics. This study focuses on the optimization for LMA removal strategy. Moreover, this study also discusses the transitional criteria from PACU to the ward.

Full description

The study recruits 180 children aged under 6-year-old undergoing elective general anesthesia. Laryngeal mask is used in procedure. The children are carried into PACU to get monitored and removal the LMA. The children are randomized into 4 groups.

Enrollment: 3 patients

Sex: Male

Ages: Under 6 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Children aged under 6 years old undergoing selected eye surgery
• Scheduled for general anesthesia

Exclusion criteria

• With systemic disease
• Respiratory system deformity
• Respiratory infection in 4 weeks

Trial design

3 participants in 4 patient groups

movement,high Aldrete score group (MH group)

Description:

LMA removal be conducted when the child's spontaneous respiratory recovers with body movement spontaneously, and the child be transited from PACU when Aldrete score reaches 9

Treatment:

Behavioral: LMA removal

movement,low Aldrete score group (ML group)

Description:

LMA removal be conducted when the child's spontaneous respiratory recovers with body movement spontaneously, and the child be transited from PACU when Aldrete score reaches 7

Treatment:

Behavioral: LMA removal

sedation,high Aldrete score group (SH group)

Description:

LMA removal be conducted when the child's spontaneous respiratory recovers but with no body movement, and the child be transited from PACU when Aldrete score reaches 9

Treatment:

Behavioral: LMA removal

sedation,low Aldrete score group (SL group)

Description:

LMA removal be conducted when the child's spontaneous respiratory recovers but with no body movement, and the child be transited from PACU when Aldrete score reaches 7

Treatment:

Behavioral: LMA removal
