Optimization for Laryngeal Mask Removal Strategy and Evaluation of Transitional Criteria From PACU in Children

Optimization for Laryngeal Mask Removal Strategy and Evaluation of Transitional Criteria From PACU in Children

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.

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.

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
