Key Takeaway
Note that awake laryngeal mask removal is associated with lower airway obstruction risk than deep removal in pediatric patients.

This meta-analysis evaluated the safety of awake versus deep laryngeal mask (LMA) removal in 1,713 pediatric patients undergoing non-airway surgery. The study analyzed overall airway complications including laryngospasm, desaturation, and breath-holding. The primary finding indicated no significant difference in overall airway complications between the two methods (RR 0.93; 95% CI [0.65-1.32], p=0.68).

Despite similar overall rates, specific outcomes differed significantly. Deep LMA removal was associated with a higher risk of airway obstruction compared to awake removal. Conversely, deep removal was associated with lower incidence of excessive secretions. Subgroup analyses indicated that sevoflurane and isoflurane universally increased airway obstruction risk. Additionally, lateral positioning during deep removal uniquely lowered desaturation risk but increased the risk of airway obstruction.

The authors noted limited data specifically for infants under 2 years of age. Clinical practice suggests awake LMA removal may be preferable to reduce airway obstruction risks, while lateral positioning may mitigate desaturation during deep removal. These findings are based on an association from a meta-analysis of RCTs.

How this fits prior evidence

This finding addresses the safety of anesthetic management in pediatric surgical settings. While previous evidence noted that sevoflurane and isoflurane can be used in head-and-neck cancer surgery, this meta-analysis specifically highlights that the use of these inhalational agents universally increased airway obstruction risk during deep LMA removal.

When surgeons remove a laryngeal mask (a device used to keep an airway open) from a child, the method of removal matters. Doctors often choose between removing the mask while the child is awake or while they are in a deep sleep under anesthesia. This study looked at 1,713 pediatric patients undergoing non-airway surgery to see which method was safer for their breathing.

The data shows that removing the mask while the child is awake leads to a lower risk of airway obstruction compared to deep sedation. While both methods showed similar rates for issues like coughing or breath-holding, the specific risk of an obstructed airway was higher when the child was deeply sedated. Additionally, using certain inhalational gases increased this risk across the board.

Positioning also plays a role in how well a child breathes during deep sedation. For example, placing a child on their side can lower the risk of oxygen levels dropping too low. However, it is important to note that there is limited data specifically for infants under two years old, so caution is advised for that very young age group.

What this means for you:
Awake laryngeal mask removal reduces airway obstruction risks in children compared to deep sedation methods.

Common questions

Is it safer to remove the breathing mask while a child is awake?

Yes, the study found that removing the laryngeal mask while a child is awake is associated with a lower risk of airway obstruction than removing it while they are in a deep sedation. While both methods had similar rates for coughing or breath-holding, the awake method specifically lowered the risk of an obstructed airway.

Are there specific risks when using certain gases during surgery?

The study found that using sevoflurane or isoflurane (common inhalational agents) universally increased the risk of airway obstruction. Because these gases increase risk, doctors must carefully weigh the choice of medication when performing a deep sedation for mask removal.

Is this finding safe for infants under two years old?

There is limited data specifically for infants under 2 years old. Because of this lack of information, caution is advised when making treatment decisions for children in this specific age group.

OBJECTIVE: This meta-analysis was designed to compare airway complication rates between deep . awake laryngeal mask airway (LMA) removal in pediatric non-airway surgery, while discussing the impact of anesthetic agents, patient position and age. METHODS: We systematically searched PubMed, Web of Science, and Cochrane Library to identify studies meeting the inclusion criteria. The primary outcome measured was the incidence of overall airway complications, which included laryngospasm, airway obstruction, desaturation, breath-holding, cough, and excessive secretions. Secondary outcomes included subgroup analyses stratified by patient positioning during LMA removal, inhalational anesthetic agents and age. RESULTS: Pooled analysis of 10 randomized controlled trials (RCTs) ( = 1,713) revealed no significant difference in overall airway complications (relative risk (RR) of 0.93, 95% confidence interval (CI) [0.65-1.32], = 0.68) or specific outcomes (laryngospasm, desaturation, breath-holding, cough) between deep and awake LMA removal; however, deep removal was associated with a significantly higher airway obstruction risk and a lower incidence of excessive secretions. Subgroup analyses demonstrated that inhalational anesthetic agents type (sevoflurane/isoflurane) did not alter most complications but universally increased airway obstruction risk, whereas positioning during deep removal reduced secretions in both lateral/supine positions yet increased obstruction, with lateral positioning uniquely lowering desaturation risk. Notably, age did not modulate the airway obstruction risk profile: children under 6 years and over 6 years exhibited comparably elevated obstruction risks with deep removal. CONCLUSIONS: This meta-analysis suggests awake LMA removal is associated with lower airway obstruction risk than deep removal, which primarily reduces secretions. Given the higher clinical severity of obstruction, clinicians may prioritize its prevention. This finding appears consistent across age groups, though caution is advised for infants (<2 years) due to limited data. Lateral positioning may mitigate desaturation during deep removal. We suggest risk-stratified protocols, with lateral positioning and monitoring advised if deep removal is performed.
