In this study we had no case of severe laryngospasm
, desaturation, and negative pressurepulmonary oedema and there was no case of aspiration.
We believe that the incidence of complications associated with LMA use, include breath holding, laryngospasm
, bronchospasm, increased air leakage, desaturation and ETI requirement, increase when adequate anesthesia depth cannot be achieved by volatile anesthetics due to air leaks secondary to the incomplete placement of the LMA.
The complications of hypoxemia and laryngeal edema were evenly spread between the CV and SV technique groups, and there was a high incidence of complete laryngospasm
in the SV group [Table 1].
The use of muscle relaxant at the correct dose before attempting intubation will prevent laryngospasm
. Extubating the patient fully awake or at a sufficiently deep level of anaesthesia is advised to prevent laryngospasm
on extubation and emergence.
Two neonates in cuffed tube group developed laryngospasm
immediately after induction with sevoflurane.

In a meta-analysis of studies comparing sevoflurane and desflurane for paediatric surgeries, it was found that desflurane had a higher overall incidence for laryngospasm
reported that topical anesthesia of respiratory tract during endoscopy with tetracaine or lidocaine to avoid laryngospasm
is very effective.
Presence of complications such as arrhythmia, laryngospasm
and agitation were recorded.
In the anaesthetic room suction apparatus should be instantly accessible, along with atropine and refrigerated suxamethonium, in case of unpredicted laryngospasm
or other airway problems occurring causing hypoxia and bradycardia (Paul 2006).
The risks of using anAEC for management of a difficult airway include dislodgement of the tube, airway trauma (e.g., endobronchial rupture (11) and lung laceration (12)), cough, laryngospasm
, failed reintubation, hypercapnia or hypoxemia, aspiration, and barotrauma.
